Preface

Welcome to Soundtrack Pro

Most experienced film and television producers know that “audio is more than half the
picture.” The art and techniques of sound recording, dialogue editing, sound effect
recording and placement, mixing, and sound design play a substantial role in how
audiences perceive the (visual) quality of a film or video. Soundtrack Pro is designed to
serve the art of motion picture sound post-production. Like the other applications in
Final Cut Studio, Soundtrack Pro was created for the film and video industry. Soundtrack Pro
gives you many specialized tools and powerful features that you can use to create
high-quality audio.
Most audio applications focus on multitrack editing or waveform editing, but not both.
Furthermore, most waveform editing applications handle media destructively—making
permanent changes to your media files. Soundtrack Pro provides the best of both worlds:
nondestructive waveform editing while working in a multitrack project.
This preface covers the following:
• About Soundtrack Pro (p. 11)
• About the Soundtrack Pro Documentation (p. 12)
• Additional Resources (p. 12)

About Soundtrack Pro
Soundtrack Pro provides film and video professionals streamlined workflows for editing
everything from individual audio files to large multitrack sound projects, including
synchronizing audio and video, editing sound in place, working with automatic dialogue
replacement (ADR), analyzing and fixing common audio problems like clicks and pops,
and creating stereo and surround sound design. Add interoperability with the other
applications in Final Cut Studio to this list of features, and you have a professional-quality
audio application designed to meet the needs of the most discerning audio editors and
mixers.

Soundtrack Pro features two types of projects: audio file projects and multitrack projects.
You use audio file projects to edit individual audio files. This is sometimes known as
waveform editing. However, unlike most waveform editing applications, Soundtrack Pro
allows you to edit your audio files nondestructively by keeping track of the actions you
have performed on your audio file. You can edit down to the file’s individual sample level
and perform tasks ranging from audio repair to sound design. You can perform edits
nondestructively using actions, which include processing effects and other operations.
You can analyze audio files for a range of common audio problems, including clicks and
pops, hum, and phase issues, and automatically fix problems that are found.
Multitrack projects look and function similarly to Final Cut Pro projects. You arrange a
multitrack project’s audio clips on the tracks in the Timeline. Multitrack projects contain
the features you expect from a high-performance and professional-quality audio editor,
including features to synchronize audio and video, work with ADR and multitake editing,
and automate volume, pan, and other changes over time using envelopes. You can record
over multiple channels to the Timeline or the File Editor or to multiple tracks in the
Timeline.

Preface

Welcome to Soundtrack Pro

Setting Up Your System

The way you set up your system depends on the audio equipment you plan to use. You
can use your computer’s speaker or headphone jack to monitor the audio output from
Soundtrack Pro. For better results, you may want to connect external monitors or speakers
to your system, so that you can monitor the audio output at a higher level of quality. You
may want to connect other external audio equipment such as an audio interface or a
mixer, particularly if you plan to record your own audio in Soundtrack Pro.
For information on system and hardware requirements, see the Read Before You Install
document on the installation DVD.
For information on installing the software, see the Installing Your Software booklet.
This chapter covers the following:
• System Considerations (p. 15)
• Connecting Equipment (p. 17)
• Example Hardware Setups (p. 21)

System Considerations
To achieve the most effective results, you should consider the following issues when
setting up your system:
• Editing and managing digital audio files can require intensive processing by your
computer. For more information, see Processor Speed and RAM.
• Storing digital audio files can require a large amount of hard disk space. For more
information, see Hard Disks.
• To make the most of Soundtrack Pro, you may wish to use a variety of audio input and
output devices. For more information, see Setting the Audio Input and Output and
Audio MIDI Setup.
• Audio units plug-ins from other manufacturers can extend the capabilities of
Soundtrack Pro. For more information, see Adding Audio Units Plug-ins to Your
Computer.

Processor Speed and RAM
Digital audio files require intensive processing by your computer. If you plan to work on
longer or more complex projects, or use multiple effects plug-ins in your projects, a
computer with a faster processor can facilitate your productivity.
Soundtrack Pro is optimized for use with computers that have a multiprocessor
architecture. Working with Soundtrack Pro projects on a multiprocessor-equipped
computer can make your workflow more efficient, especially when creating longer or
more complex projects.
If you plan to work on large projects, it’s useful to have extra random-access memory, or
RAM, installed in your computer. Additional RAM allows you to play back more files
simultaneously, use a greater number of effects plug-ins, and keep several multimedia
applications open at the same time.

Hard Disks
In addition to having a computer with a fast processor and a lot of extra RAM, it’s also a
good idea to have a large hard disk with plenty of available space to store the media
(audio and video) files you use with Soundtrack Pro. As you work with the application,
you’ll likely want to acquire a large collection of sounds to use in your Soundtrack Pro
projects. Hard disk performance is a critical aspect of your editing system: the storage
capacity and data rate of your disks must match or exceed the requirements of the audio
(and video) formats you are using.
If you store media files on an external hard disk, make sure the disk has a fast enough
seek time and a high enough sustained data transfer rate for use with video and audio
files. Consult the manufacturer’s specifications.
Important: Every minute of stereo digital audio (recorded using a 44.1 kHz sample rate
and 16-bit depth) requires roughly 10 MB of hard disk space. If you plan to record large
amounts of audio in Soundtrack Pro, you may want to record to a hard disk dedicated to
storage for your Soundtrack Pro projects.

Setting the Audio Input and Output
You can set the default input and output devices for Soundtrack Pro with the Audio MIDI
Setup utility.
To select a default output device
Do one of the following:

Double-click Audio MIDI Setup in the Utilities folder, then choose the device from the
Default Output pop-up menu.

Choose Apple menu > System Preferences, click Sound, then click Output. Select the
audio interface in the list that appears.

Chapter 1 Setting Up Your System

To select a default input device
Do one of the following:

Double-click Audio MIDI Setup in the Utilities folder, then choose the device from the
Default Input pop-up menu.

Choose Apple menu > System Preferences, click Sound, then click Input. Select the audio
interface in the list that appears.

Audio MIDI Setup
The Audio MIDI Setup utility is a program that comes with Mac OS X for adjusting a
computer’s audio input and output settings and managing MIDI devices. You can select
audio channel input and output devices, configure output speakers, set clock rates, and
control levels. You may also be able to open a configuration utility provided by your audio
device.
For more information, go to http://developer.apple.com/audio/overview.html.

Adding Audio Units Plug-ins to Your Computer
Soundtrack Pro includes an extensive set of professional-quality effects plug-ins.
Soundtrack Pro uses effects in the Audio Units plug-in format, the native plug-in format
of Mac OS X.
Audio Units plug-ins are also available from third-party manufacturers. When adding
third-party effects to your computer, be sure to read the documentation, including any
Read Me and installation files, that came with the plug-in. Supported Audio Units effects
plug-ins appear in the Effects window under the manufacturer’s name.
Soundtrack Pro does not support VST, ASIO, MAS, or RTAS effects plug-ins.

Connecting Equipment
You can use a variety of audio equipment with Soundtrack Pro for both recording and
playback. For information on connecting a specific piece of equipment to your computer,
read the documentation that came with the equipment. For general information about
connecting a control surface to your computer, see Connecting Control Surfaces.
Final Cut Studio editing systems can be configured to meet the most demanding
professional requirements. An advanced editing system can be built by expanding the
basic system described in the Final Cut Pro User Manual. The following list includes
equipment commonly used in Final Cut Studio editing systems:
• Macintosh computer with Final Cut Studio installed: The core of your editing system
• Professional video and audio devices: For capturing footage and outputting finished
projects. (For more information about video and audio devices, see Working with
Professional Video and Audio Equipment.)

Chapter 1 Setting Up Your System

• External video and audio monitors: For viewing and listening to your program in its final
image and audio quality
• Video and audio interfaces: For connecting professional and non-FireWire devices to
your editing system
• RS-422 serial device control interfaces: For remote device control during capture and
output
• Video, audio, and remote device control cables: For separate video, audio, and remote
device control connections. Unlike a basic DV editing system that uses a solitary FireWire
cable to transfer video, audio, and remote control signals, many professional
configurations require separate cables for each of these signals.
• Additional scratch disks: One or more internal or external hard disks, a RAID, or a
connection to a storage area network (SAN)
• Control surfaces: Hardware controls that let you mix and edit your projects with greater
flexibility and precision than using a mouse to move onscreen controls

Video and Audio Input and Output Devices
An input device is used to transfer footage into your computer. For output, you record
your finished movie to an output device. Basic editing systems use a DV camcorder or
deck as both an input and output device. Professional editing systems may use multiple
video decks to capture and output to different video formats. Although Soundtrack Pro
does not support video capture from devices such as camcorders or VTRs, it does support
recording from a variety of digital audio devices.
To connect non-FireWire devices to your computer, you also need a third-party video or
audio interface. For more information, see Video Interfaces.
Video Device
This is a VTR or camcorder you connect to your computer to capture and output media.
The connectors and signal format on your video device determine what kind of video
interface your computer needs to connect to your device.

Audio Device
This is a device, such as a digital audio tape (DAT) recorder or multitrack audio recorder,
that lets you capture or output audio independently from video.

Chapter 1 Setting Up Your System

Note: When using external audio devices, it’s a good idea to connect them before opening
Soundtrack Pro.

Video and Audio Interfaces
An interface is a device that adds physical video or audio connectors to your computer
so that you can connect your Final Cut Studio system to other professional equipment
(such as video or audio decks and monitors).
Interfaces provide input and output connectors that aren’t included with your computer.
For example, if you want to output multiple audio channels to an analog audio mixer or
digital multitrack, you need an audio interface that has XLR, 1/4" tip-ring-sleeve (TRS),
AES/EBU, or ADAT Lightpipe output connectors.
You may also want to consider adding a third-party interface to your system if:
• You need to capture or output many audio channels at once
• You are integrating Final Cut Studio into a professional broadcast environment that
requires SDI, HD-SDI, or other non-FireWire video and audio connections
• You need to capture, edit, and output full-resolution, uncompressed video signals
instead of DV video (which is compressed)
• You are digitizing video from an older analog VTR (such as a Betacam SP deck) that
does not have digital video outputs or remote control via FireWire
Third-party video and audio interfaces can be installed in one of your computer’s PCI
Express slots, connected to the USB port, or connected via FireWire.
For more information about selecting and connecting an audio interface for use with
Soundtrack Pro, see Setting Up an Audio Interface.

External Audio and Video Monitoring
In the final stages of post-production, external video and audio monitors are essential to
ensure the quality of your movie. Editing systems focused on these final phases of
post-production are often called finishing systems.

Chapter 1 Setting Up Your System

External Audio Speakers and Monitors
You can play back audio through your computer’s speakers or headphone jack, but the
audio output may not be high enough for you to evaluate your music at a professional
level of quality. Connecting external speakers or monitors to your system allows you to
hear the audio output with greater fidelity and a wider dynamic range. During the final
mix, it is important to monitor your audio so that it matches the listening environment
where the final project will be shown. For detailed information on connecting external
speakers to your audio interface, see the documentation that came with the speakers.

Setting Up a Proper Audio Monitoring Environment
Room shape and material are just as important as the quality of the speakers themselves.
Every surface in a room potentially reflects sound, and these reflections mix together
with the sound originating from the speakers. Rooms with parallel walls can create standing
waves, which are mostly low-frequency sound waves that reinforce and cancel each other
as they bounce back and forth.
Standing waves cause some frequencies to be emphasized or attenuated more than
others, depending on your listening position. When you mix in a room that creates
standing waves, you may adjust certain frequencies more than necessary. However, you
may not notice until you play back your audio in a different listening environment, in
which those frequencies may sound overbearing or nonexistent.
Tip: A much cheaper alternative to building new walls is to mount angled pieces of
material to the existing walls to eliminate parallel surfaces.
If the material in a room is very reflective, the room sounds “brighter” because high
frequencies are easily reflected. Mounting absorbing material (such as acoustic foam) on
the walls can reduce the brightness of a room. A “dead room” is one that has very little
reflection (or reverberation). Try to cover any reflective surfaces in your monitoring
environment.
Amplifiers
If you are recording audio from microphones and are not running the microphone’s signal
through a mixer with a microphone pre-amplifier, you need to connect an amplifier to
boost the microphone’s signal before sending it to the computer. If you are connecting
monitors or speakers that are not self-powered, you also need to connect them through
an amplifier.

Chapter 1 Setting Up Your System

Mixers
Connecting a mixer to your system allows you to record audio from multiple microphones
or instruments simultaneously, to play back the output from your computer through
connected monitors or speakers, and to control the volume levels of both the audio input
and output. Professional-quality mixers have a number of additional features, including
equalization (EQ) controls, auxiliary sends and returns for adding external effects, and
separate monitor and mix level controls. Mixers may also include inboard preamplification
for microphones, making the use of a separate amplifier unnecessary.
Control Surfaces
Soundtrack Pro supports control surfaces that use the Mackie Control, Logic Control, and
Euphonix EuCon protocols. For information on connecting and using control surfaces,
see Using Control Surfaces with Soundtrack Pro.
External Video Monitors
When you design and edit a video soundtrack, it’s ideal to watch the video on a monitor
similar to the one you will use for the final screening. An external video monitor can
display color, frame rate, and interlaced scanning more accurately than your computer
display. (For information on connecting professional video devices, see Connecting
Professional Video Devices.)

If you are working on an NTSC or a PAL project, you should watch it on an external video
monitor that shows the video interlaced. For more information about external video
monitoring, see the Final Cut Pro User Manual.

Setup with a PCI Express Video Interface Card with Breakout Box
Many PCI Express cards aren’t big enough to fit all of the necessary video and audio
connectors. In these situations, a breakout box is connected to the PCI Express card via
a multipin connector on a long cable, and the connectors are accessible on the breakout
box instead of on the back of the PCI Express card. A breakout box is also useful because
it allows you to place the connectors somewhere more convenient than the back of your
computer, such as on an equipment rack or a desktop.
This setup uses the following equipment:

Setup for Stereo Mixing
By default, Soundtrack Pro is set up for stereo mixing. Most video editing suites use
nearfield monitors, which are speakers designed to be listened to at fairly close range.
Speakers should be at least a foot or two away from any walls to prevent early reflections
of sound that combine with and muddy the original sound.
Position the speakers as far from your listening position as they are from each other
(forming an equilateral triangle). For example, if the distance between the speakers is six
feet, you should place yourself six feet from each speaker. The apparent width of the
sound stage, or stereo image, increases as the distance between the speakers increases.
However, if the two speakers get too far apart, sound information appearing in the center
(between both speakers) starts to disappear.

Setup for Surround Mixing
For complete instructions on setting up the surround mixing tools in Soundtrack Pro, see
Setting Up Soundtrack Pro for Surround.

Chapter 1 Setting Up Your System

The Soundtrack Pro Interface

Soundtrack Pro is designed to handle every aspect of creating audio for a video or film
project, from multitrack recording to advanced audio processing and mixing. You can
use Soundtrack Pro together with Final Cut Pro as a complete audio post-production
solution that is powerful, yet also elegant and flexible.
This chapter covers the following:
• Soundtrack Pro Window Organization (p. 28)
• Project Pane (p. 35)
• Toolbar (p. 36)
• Transport Controls (p. 36)

Soundtrack Pro Window Organization
There are several panes that comprise the Soundtrack Pro window that you’ll use while
you are creating audio projects. You may want to open Soundtrack Pro so you can view
these panes and familiarize yourself with the interface.

To open Soundtrack Pro
In the Finder, double-click the Soundtrack Pro icon in the Applications folder.
You may also choose to add the Soundtrack Pro icon to the Dock for easier access. For
more information, see Mac Help.
The Soundtrack Pro window is arranged into several areas.

Project pane

Left pane

Right pane

Lower pane

Transport controls (project pane)

• Project pane: This is reserved as the central “canvas” for the multitrack Timeline and
for individual audio file projects.
• Left, lower, right panes: Task-specific tabs are docked in the left, lower, and right panes.
By default, the tabs are grouped by function and are laid out for a streamlined audio
post-production workflow.
• Transport controls: Use these controls at the bottom of the window to play back projects
that you open in the project pane.

Chapter 2 The Soundtrack Pro Interface

Below is the standard, default layout of the Soundtrack Pro window. You can easily
rearrange the tabs and resize the panes to suit your needs and then save the custom
layouts for future use.
Video tab

Standard layout
Toolbar

Meters tab

Browser tab

Details tab

Transport controls

Note: At any time, you can revert to the default layout by choosing Window > Layouts
> Standard, or pressing F1. Also, you can save any custom layouts you create. For more
information on managing layouts, see Using Project Layouts.

Chapter 2 The Soundtrack Pro Interface

Showing and Hiding the Panes
Tabs are grouped by function to optimize your workflow. For example, the media tabs
related to input and output functions (Meters, Recording, Search, Browser, and Favorites)
are located in the right pane by default. When you are finished with media input, you
can close the entire right pane by choosing Window > Toggle Right Pane, and thereby
allow more horizontal space for the project pane and the lower pane. If you hide a pane,
then later choose to show a tab that is in the hidden pane, the pane reappears and shows
all tabs in that pane.

Chapter 2 The Soundtrack Pro Interface

Or, for example, you may wish to work exclusively in the Timeline or the File Editor project
view and dedicate the entire Soundtrack Pro window to that view.

Timeline view

File Editor view

Chapter 2 The Soundtrack Pro Interface

Because hiding and showing different panes of the Soundtrack Pro window is so
convenient, you will probably use this feature frequently during the course of a project.
Press Control–A to toggle the left pane, Control–S to toggle the bottom pane, and
Control–D to toggle the right pane. For more information, see Soundtrack Pro
Keyboard Shortcuts. The default toolbar also contains buttons to toggle the appearance
of the panes.

If your portable computer has a Multi-Touch trackpad, you can use the swipe gesture to
show and hide panes. A swipe is quickly sliding one or more fingers across a Multi-Touch
trackpad. Swipe left and right to show and hide the left pane or right pane. The pane
affected by horizontal swipe gestures is determined by the Horizontal Swipe Gesture
Affects preference setting in Soundtrack Pro Preferences. For more information, see
General Preferences. Using the swipe gesture up or down shows or hides the bottom
pane.

Chapter 2 The Soundtrack Pro Interface

Showing and Hiding Tabs
In addition to showing and hiding entire panes, you can also choose to show and hide
individual tabs in panes. You can toggle the appearance of individual tabs by choosing
Window > Tab and then choose the name of the tab you wish to show or hide. A
checkmark next to a tab in the menu list indicates the tab is currently showing. If a tab
is part of a hidden pane, and you choose to show the hidden tab, the pane holding the
tab reappears with all tabs in that pane.

Tab menu

Chapter 2 The Soundtrack Pro Interface

Rearranging Tabs
At any time, you can rearrange the layout by tearing off individual tabs and docking them
in other panes, or simply have them float over the Soundtrack Pro window. There are
numerous possible combinations. Mix and match the tabs to suit your particular workflow
needs.

The Meters, Search, and
Browser tabs have been
moved from the right
pane and docked in
the left pane.

Chapter 2 The Soundtrack Pro Interface

Project Pane
The project pane is the central “canvas” where you work on your projects in either the
multitrack Timeline or the File Editor project view. Use the Timeline (shown below) to
arrange audio clips in multitrack projects. Use the File Editor project view for individual
audio file projects.

Conform
The Conform tool helps sound editors handle picture changes. Conforming a sequence
is the act of incorporating changes sent from the picture editor into a different, changed
version of a sequence being used by the sound editor. The sound editor revisits all of the
audio edits, ensuring that they line up with new video footage and inserting or deleting
any added or deleted media. Soundtrack Pro Conform makes this merging procedure
more efficient and less tedious.
For more information about the Conform tool, see Using Conform with Final Cut Pro.

About Multitrack and Audio File Projects
Soundtrack Pro has two native project file formats to support state-of-the-art multitrack
audio editing and powerful nondestructive audio waveform editing:
• Multitrack project (.stmp): Similar to a Final Cut Pro project, this file contains multiple
tracks with clips that refer to media files elsewhere on your disk.
• Audio file project (.stap): This format allows nondestructive editing of audio files.

Multitrack Projects
Multitrack projects contain multiple audio tracks in the Timeline. As in a Final Cut Pro
project, importing a media file creates a clip in Soundtrack Pro that then refers to the
original media file. You can arrange audio clips within tracks and synchronize them to a
single video clip in the video track.

You can mix a multitrack project using track controls for volume, pan, mute, solo, effects,
and effect parameters. These controls are available both in the Timeline and in channel
strips in the Mixer. You can create additional audio busses for effect sends. You can group
audio track outputs together with submixes. Tracks, busses, and submixes can be exported
to individual audio files, or a mixdown of all the tracks can be exported to a stereo or
multichannel audio file. These exported files can then be imported into Final Cut Pro.

Audio File Projects
Soundtrack Pro allows you to edit individual audio files (sometimes known as waveform
editing) using Soundtrack Pro audio file projects. However, unlike most waveform editing
applications, Soundtrack Pro allows you to edit your audio files nondestructively by
keeping track of the actions you have performed on your audio file. For more information
about Soundtrack Pro audio file projects, see Working in the File Editor.
You can remove, disable, or reorder past actions at any time or save actions as AppleScript
documents that you can use to batch process other audio files. Actions you can perform
include trimming audio, copying and pasting parts of the waveform, normalizing or
amplifying levels, applying effects, and applying noise, pop, and click reduction.
Soundtrack Pro audio file projects are stored in Mac OS X packages (or bundles). A package
appears to be a single file in the Finder but actually contains a collection of files such as
the original audio file, temporary render files, and the list of actions applied to your audio
file.
Important: So that you benefit from nondestructive editing, the default option for saving
edited audio files is as a Soundtrack Pro audio file project. Soundtrack Pro usually does
this automatically any time you apply any command or effect from the Process menu to
a clip in the Timeline. For more information on when Soundtrack Pro automatically creates
audio file projects, see How Source Audio File Editing Works in a Multitrack Project.

Supported Audio File Formats
You can open and add audio files in the following formats:
• AIFF
• WAVE
• Broadcast WAVE
• Sound Designer II
• NeXT
• QuickTime (.mov) audio files
• CAF (Apple Core Audio Format)
• Soundtrack Pro audio file project

Chapter 3 Basics of Working in Soundtrack Pro

Compressed formats such as MP3 and AAC (except protected AAC) files are also supported,
although these must be internally decompressed to a linear PCM format.
Soundtrack Pro supports audio files with any sample rate between 8 kHz and 192 kHz
and any of the following bit depths: 8, 16, 24, 32, and 32-bit floating point. Up to 24 audio
channels are supported in a single file.
When you set a sample rate and play a file, Soundtrack Pro plays at the nearest sample
rate your hardware can support.
Note: Files with lower bit depths or sample rates do not have the same playback quality
as formats with higher bit depths or sample rates.
You can also open and add the following types of multichannel files:
• AIFF
• WAVE
• Broadcast WAVE
• QuickTime
• Single Folder Multi-mono AIFF and WAV

Supported Video File Formats
Soundtrack Pro supports the following file formats:
• Standard QuickTime-compatible file formats. You can import a QuickTime movie (.mov)
file into a Soundtrack Pro project, and you can import an MPEG-2 (.m2v) file if you have
installed the QuickTime MPEG-2 Playback Component.
• Video files using NTSC, PAL, HD, and other formats supported by QuickTime
For more information about importing video files, see Working with Video in
Soundtrack Pro.

About Looping and Non-Looping Files
Soundtrack Pro supports two types of audio files: looping and non-looping files. Most
audio files are non-looping files unless they contain tags for tempo, key, and other
information.
Many of the Apple Loops that come with Soundtrack Pro, as well as other tagged audio
files, can be looping files. Looping files may contain music, rhythmic sounds, or other
repeating patterns. You can resize a looping file to fill any amount of time. Looping files
adjust to the project tempo and key, letting you use loops recorded in different keys and
at different tempos in the same project.

Chapter 3 Basics of Working in Soundtrack Pro

Non-looping files do not adjust to the project tempo and key. You can shorten or lengthen
a non-looping file, but lengthening it beyond the size of the original file adds only silence
to the lengthened part. You can search for non-looping files in the Search tab using the
Search text field.
Both looping and non-looping files can contain tags with information about the file,
including mood, genre, and musical instrument. Soundtrack Pro recognizes tags in audio
files intended for use with loop-based music applications. You can open an audio file in
Apple Loops Utility and add tags, and can convert a looping file to a non-looping file, or
convert a non-looping file to a looping file. For information about tagging audio files
using Apple Loops Utility, see the Apple Loops Utility User Manual.

Setting Up Your Workspace
You can choose from several ways to set up the Soundtrack Pro workspace to suit your
display size and workflow, depending on the type of project you are creating. You can
arrange, reorder, and detach tabs throughout Soundtrack Pro and add and reorder buttons
in the Toolbar. You can show and hide different panes (areas) of the Soundtrack Pro
window. You can also create layouts for different tasks and switch between them.

Basic Window Controls
You can move, resize, or minimize a project’s windows. Most windows feature tabs, which
give you flexibility in arranging the visual elements of a project.

Using Tabs
Soundtrack Pro uses tabs so you can quickly access different project views and controls.
You can switch between projects and between different tabs. Clicking the tab you want
makes it active and brings it to the front. You can rearrange and reorder the tabs to easily
access the ones you use frequently.

Chapter 3 Basics of Working in Soundtrack Pro

To reorder tabs
Drag a tab left or right in the window’s tab area.

You can also detach a tab from its docked position, which creates a separate resizable
window for the tab that can be dragged or resized. For example, you can drag the Favorites
tab to a new location so that you can easily move items from the Search tab to the Bin
tab.

To detach a tab
Drag the tab out of its docked position in the window to create a separate window for
the tab.

To attach (dock) a tab
Drag the tab to the top of any pane of the Soundtrack Pro window (except the top center
project pane, which is reserved for the Timeline and the File Editor project view).

Using Project Layouts
Soundtrack Pro lets you save and recall preset window arrangements called layouts, so
that you can optimize your workspace for different tasks and different display sizes. You
can show, hide, and resize windows, then save each window arrangement as a layout.
To save a project layout
1 Arrange the application windows as you want them to appear.
2 Choose Window > Save Layout.
3 In the Save dialog, type a name for the layout, then click Save.
The layout is saved and appears in the Layouts submenu.

Using Keyboard Shortcuts and Shortcut Menus
Soundtrack Pro offers several methods for performing commands. You can choose
commands from the menu bar at the top of the screen or from contextual shortcut menus,
or you can use keyboard shortcuts to perform many commands. Most people work fastest
using keyboard shortcuts; others prefer to use shortcut menus or the mouse to access
commands in the menu bar. Experiment to find out which method best suits your editing
style.

Using Keyboard Shortcuts
Keyboard shortcuts let you perform commands in Soundtrack Pro by using the keyboard
instead of by pointing and clicking. These shortcuts can help you work more efficiently.
For example, to create a new audio file project, you’d press Command-Shift-N; to zoom
in, you’d press Command–Equal Sign (=).
Note: The default keyboard shortcuts for tasks are presented throughout this volume as
well as in menu commands and tooltips (tooltips appear when you move the pointer
over a control in Soundtrack Pro and show the name of the control, as well as the current
shortcut key or keys assigned to that control).

Using Shortcut Menus
Shortcut menus (also called contextual menus) are available in nearly every window or
pane and offer a quick way to perform various tasks. The commands available in a shortcut
menu depend on the location of the pointer. For example, a shortcut menu in the File
Editor shows options different from those available in a shortcut menu in the Timeline.

Chapter 3 Basics of Working in Soundtrack Pro

To view and use a shortcut menu
1 Do one of the following:
• Press the Control key, then click an item (this is called Control-clicking).
• Control-click an area in a window or pane in Soundtrack Pro.
• If you have a three-button mouse connected to your computer, you can right-click.
2 In the shortcut menu that appears, choose the command you want, then release the
mouse button.

Undoing and Redoing Changes
As you edit clips and perform other operations in both multitrack and audio file projects,
you might need to use the Undo and Redo commands. For example, if you don’t like the
last change you’ve made to a project, it can usually be undone. Then, if you decide you
prefer to keep the change you just undid, you can redo the command immediately after
using Undo.
You can also use the Undo and Redo commands as a quick way of trying out changes to
your project. You can make changes to any aspect of the project, then use Undo to step
back through changes you don’t like to the project’s previous state. If you change your
mind after undoing a change or set of changes, you can always use Redo to recover the
changes. At any point, you can save a new version of the project using the File > Save
As command.
You can use the Undo command repeatedly to undo every change made since the project
was last saved.

To undo the last change
Choose Edit > Undo [item] (or press Command-Z).
The [item] in the menu changes to show the last command or operation.
You can use the Redo command repeatedly to redo every undone change since the
project was last saved.

To redo the last change
Choose Edit > Redo [item] (or press Command-Shift-Z).
The [item] in the menu changes to show the last command or operation.

About Changing Values and Timecode Entries
Soundtrack Pro includes several types of value entry methods. Most of them have features
that can make changing the values or timecode fields easy to do.

Using Value Sliders
There are two methods used to enter general numeric values:
• Traditional sliders with separate numeric entry fields
Separate slider and
numeric entry field

• Value sliders that combine the slider with the numeric entry field. Value sliders allow
you to enter a specific number in the value field or to drag in the value field to set a
value. When using the value sliders, you can use a modifier key to make normal, small,
or large value adjustments. Dragging in the middle area (where the number is) works
the same as an ordinary slider; dragging to the right increases the value and dragging
to the left decreases the value. Additionally, you can click the right or left arrow to
change the value one step at a time. You can also double-click the number itself and
type a new number to enter a specific number in the value field.
Value slider with
combined slider and
numeric entry field

To change values in normal increments
Do one of the following:

µ
µ
µ

Drag left or right in the value field.
Click the left arrow to decrease a value, or click the right arrow to increase a value.
If you have a three-button mouse with a scrollwheel, click in the value field and use the
scrollwheel on the mouse.
To change values in fine increments
Do one of the following:

µ
µ

Option-drag in the value field.

If you have a mouse with a scrollwheel, Option-scroll in the value field.

Option-click the left arrow to decrease a value, or Option-click the right arrow to increase
a value.

Chapter 3 Basics of Working in Soundtrack Pro

To change values in coarse increments
Do one of the following:

µ
µ

Shift-drag in the value field.

If you have a mouse with a scrollwheel, Shift-scroll in the value field.

Shift-click the left arrow to decrease a value, or Shift-click the right arrow to increase a
value.

When a value slider or value field is active (highlighted), press Tab to move to the next
field.

Using Timecode Value Sliders
Soundtrack Pro uses timecode value sliders for timecode entry fields. In addition to being
able to enter timecode values directly, you are able to scrub the timecode value by
dragging.
If you place the pointer over a segment of the timecode, small arrows appear above and
below that segment.

You can drag up or to the right to increase the value in that segment (values in segments
to the left also increment if your dragging causes the selected segment to roll over).
Dragging to the left or down decreases the value. You can hold down the Option key to
make the value changes slower or the Shift key to make them faster.
Alternatively, you can click the up and down arrows on each side of the timecode value
or press the keyboard’s Up Arrow and Down Arrow keys to increase or decrease the
timecode value.

You can control which segment is affected by the up and down arrows by selecting a
segment so that a caret (^) appears below the segment. You can also use the keyboard’s
Left Arrow and Right Arrow keys to select other segments.

Scrubbing Audio
You can scrub a multitrack project in the Timeline or scrub an audio file project in the
File Editor. Scrubbing the project lets you hear the audio at the playhead position as you
drag the playhead, so you can find a particular sound or event in the audio file.

Chapter 3 Basics of Working in Soundtrack Pro

You can scrub audio using either the Scrub tool or the playhead. For information about
scrubbing, see Scrubbing Audio Files.

Scrubbing Video
In projects containing a video file, the video scrubs in the Video tab in sync with the audio
as you scrub in the Timeline or the File Editor tab.
As you drag audio clips, markers, envelope points, or other items in the Timeline or the
File Editor tab, the video scrubs at the start point of the item being dragged. Dragging
multiple items scrubs the video at the start point of the item under the pointer.
You can use the Multipoint Video HUD as a visual tool for precisely positioning sound
effects and other audio clips in a video program. For more information, see Scrubbing
and Spotting with the Multipoint Video HUD.

Controlling Playback with the Transport Controls
You use the transport controls to control playback of your project. The transport controls
let you set the playhead to various points in time, start and stop playback, activate the
cycle region, and start a recording session to record your own audio.

region is active or inactive. If no cycle region is set, clicking the Cycle button sets the
project to repeat from the beginning when the playhead reaches the end of the project.
For information on setting the cycle region, see Working with the Cycle Region.
• MIDI Sync button: Synchronizes playback with incoming MIDI Clock and MIDI Timecode
(MTC) signals.

Controlling Playback Using Keyboard Shortcuts
There are a number of keyboard shortcuts you can use to control playback of your project.
To use keyboard shortcuts, the pointer cannot be in a text field.
• Space bar: Plays back the project from the current playhead position. If the project is
playing, pressing the Space bar stops project playback. This is equivalent to clicking
the Play button.

As the project plays, the playhead shows the point in the project currently playing.

Chapter 3 Basics of Working in Soundtrack Pro

Soundtrack Pro lets you set the playhead and control playback of your projects in several
different ways. You can use the transport controls or keyboard commands to start and
stop playback and set the playhead to different points in time. You can also set a cycle
region to repeat playback of a specific part of the project.

Setting the Playhead Quickly
The playhead appears as a thin black line running vertically through the Timeline in
multitrack projects, and through the waveform display in audio file projects. Where it
crosses the Time ruler, the top of the playhead has a triangular handle that makes it easier
to see its position onscreen and drag the playhead.
To set the playhead
Do one of the following:

Click anywhere in the Timeline (in a multitrack project) or the File Editor (in an audio file
project) to set the playhead to that position.
Note: You can set Soundtrack Pro to require a click in the Ruler to move the playhead.
For more information, see General Preferences.

Drag the triangular handle at the top of the playhead to the position you want to set it.
As you drag the playhead, you hear the audio at the current playhead position.

Drag the playhead
where you want it
or click in the Timeline.

Drag the playhead
where you want it
or click in the
waveform display.

Chapter 3 Basics of Working in Soundtrack Pro

When you set the playhead, it snaps to the nearest Snap To position if snapping is turned
on. For information on setting the Snap To value, see Using Snapping. You can also set
the playhead by using the transport controls or the Playhead Location value slider.
Note: If you click the Time ruler, you may accidentally activate the cycle region. Press
Option-X to remove the cycle region. Press C to turn the cycle region on or off. For more
information about using the cycle region, see Working with the Cycle Region.

Setting the Playhead Using the Time Display
When a project is playing, the Time display constantly updates to show the current
position of the playhead in both Time-based and Beats-based formats. You can also set
the playhead to a new position by entering the position in the Time display.
The arrangement of the Time-based and Beats-based positions in the Time display changes
depending on the time format of the project. The position matching the time format of
the project appears in large, white numerals in the upper part of the Time display, and
the other position appears below it in smaller, gray numerals. Each position is labeled for
quick visual recognition.
For information on setting the project time format, see Setting Project Properties.

To set the playhead using the Time display
Select either the Time or Beats position in the Time display, then enter a new position.
You can select the entire position or part of the position.
Enter a time position
in the Time area.
Enter a beat position
in the Beats area.

Entering Time-Based Units
When you set the playhead by entering a Time-based position in the Time display, you
don’t need to enter all of the punctuation. Soundtrack Pro automatically adds the correct
punctuation for the format of the Time display.
If you enter a partial number, Soundtrack Pro formats it with the rightmost pair of numbers
as frames and with each successive pair of numbers to the left as seconds, minutes, and
hours. Numbers omitted from a complete time position are interpreted as zeros. For best
results, always enter delimiters to separate each division of time.

Chapter 3 Basics of Working in Soundtrack Pro

For example:
• If you enter 01234321: Soundtrack Pro interprets it as 01:23:43;21. This stands for 1 hour,
23 minutes, 43 seconds, and 21 frames.
• If you enter 01.23: Soundtrack Pro interprets it as 00:00:01;23. This stands for 1 second
and 23 frames.
You can select only part of the position in the Time display and enter a new number for
that position. For example, you can select only seconds, or minutes and seconds. The
other categories keep their present values. You can enter a time position in timecode
format, in a way similar to the way you enter timecode in Final Cut Pro.
Entering Beats-Based Units
When you set the playhead by entering a Beats-based position in the Time display, you
enter periods between numbers to separate measures, beats, and beat divisions.
Soundtrack Pro fills out the digits in the beat division category with zeros.
For example:
• If you enter 123: Soundtrack Pro interprets it as 123.1.000. This stands for the 123rd
measure, 1st beat, with no added beat divisions.
• If you enter 12.3: Soundtrack Pro interprets it as 12.3.000. This stands for the 12th
measure, the 3rd beat, with no added beat divisions.
• If you enter 1.2.3: Soundtrack Pro interprets it as 1.2.300. This stands for the 1st measure,
the 2nd beat, and 300/1000 of a beat (because each beat division is 1/1000 of a beat).
You can select only part of the position in the Time display and enter a new number for
that position. For example, you can select only measures, or measures and beats. The
other categories keep their present values.

Setting the Playhead Using the Playhead Location Value Slider
Below and to the left of the transport controls is the Playhead Location value slider. When
a project is playing, the Playhead Location value slider constantly updates to show the
current position of the playhead. You can set the playhead by entering a new position
in the Playhead Location value slider.

Chapter 3 Basics of Working in Soundtrack Pro

Using Snapping
When you move and resize clips in the Timeline, or select part of an audio file in the File
Editor, you usually want them to start and end at a specific point in time. To synchronize
clips with a video, you may want to position them in line with a specific frame. In a
music-based project, you may want to align clips with measures and beats. Soundtrack Pro
includes a snapping feature that causes clips, the playhead, and other items in the Timeline
and File Editor to “snap” to the nearest Snap To position.
Snapping applies to the following operations:
• Dragging audio clips to the Timeline
• Moving audio clips
• Resizing audio clips
• Setting the playhead
• Setting the cycle region
• Inserting markers
• Moving markers
• Selecting Timeslices
• Adding envelope points
• Moving envelope points
• Moving crossfade edges
You can use snapping to ensure that audio clips are synchronized to a measure or beat,
that they begin playing back at a precise point in time, and that they are precisely aligned
with other clips in the Timeline.
When you turn on snapping, the item you are moving snaps to the nearest Snap To
position in the Timeline. The available Snap To values depend on the time format of the
project.
For projects set to Time-based format, the available Snap To values are:
• Ruler ticks
• Seconds
• Frames
• Clips on Adjacent Tracks
• Markers
For projects set to Beats-based format, the available Snap To values are:
• Ruler ticks
• 1/4 notes

Chapter 3 Basics of Working in Soundtrack Pro

• 1/8 notes
• 1/16 notes
• 1/32 notes
• 1/64 notes
• Markers
• Clips on Adjacent Tracks

To turn snapping on
Choose View > Snap (or press N).
A checkmark next to the menu item indicates that snapping is turned on. Choose View
> Snap again to turn snapping off.

To set the Snap To value
Choose View > Snap To, then choose a value from the submenu.

You can temporarily reverse the current snapping state while you work in the Timeline.
When snapping is turned on and Markers is chosen in the Snap To submenu, clips in the
Timeline snap to the playhead as well as to markers.

To temporarily reverse the snapping state
Select the item in the Timeline, then hold down the Command key as you drag the item.
If snapping is turned on, Command-dragging lets you move the item without having it
snap to the nearest Snap To position. If snapping is turned off, the item snaps to the
nearest Snap To position. When you release the Command key, items moved in the
Timeline follow the normal snapping state.

Chapter 3 Basics of Working in Soundtrack Pro

Reconnecting Media Files
Because Soundtrack Pro multitrack projects contain references to media files, and not
the files themselves, a multitrack project cannot play back if the media files it uses are
erased or moved. When you open a multitrack project in Soundtrack Pro, the application
checks to see if the media files it uses exist in the same location as they did when the
project was last opened. If the media files are not in the expected location, Soundtrack Pro
displays a Can’t Find File dialog with three choices:
• Skip All: Opens the project without reconnecting any missing files.
• Skip File: Opens the project without reconnecting the missing file.
• Locate: Presents a dialog that lets you locate the missing file and reconnect it to the
project.
If you choose to open the project without reconnecting its files, you can reconnect
individual audio files from the Timeline or the Bin tab and reconnect a video file in the
video track in the Timeline. You can also use the Reconnect Offline Files command to
reconnect multiple files.
Important: When reconnecting media files that include QuickTime movies, the reconnect
operation obeys the Referential QuickTime Movies option set in the Soundtrack Pro
Preferences window. For more information, see General Preferences.
To reconnect an audio file
1 Do one of the following:
• Select the clip in the Timeline, then choose Clip > Reconnect [filename].
• Control-click the clip in the Timeline, then choose Reconnect [filename] from the shortcut
menu.
• Select the clip in the Bin tab, then choose Reconnect [filename] from the Media pop-up
menu.
• Control-click the audio file in the Bin tab, then choose Reconnect [filename] from the
shortcut menu.
2 In the dialog that appears, locate the audio file you want to reconnect.
3 Click Open to reconnect the file.
To reconnect a video file
1 Control-click the video clip in the video track, then choose Reconnect Media Files from
the shortcut menu.
2 In the dialog that appears, locate the video file.
3 Click Open to reconnect the file.
To reconnect all offline files
1 Choose File > Reconnect Offline Files.

113

You can also open a recently open project by choosing it from the File > Open Recent
menu, or open a project by dragging it onto the Soundtrack Pro icon in the Dock.
You can have multiple projects open in Soundtrack Pro and cut and paste between them,
but you can only play one project at a time. You can open projects created with earlier
versions of Soundtrack and Soundtrack Pro, but you can only save them as multitrack
projects (with the extension .stmp).
At any time while you are working, you can close a multitrack project.

To close a project
Select the project’s tab in the project pane, then choose File > Close Project (or press
Command-W).

Creating a Multitrack Project from Final Cut Pro Clips or
Sequences
A convenient and powerful audio post-production workflow for any film or video project
is sending a Final Cut Pro sequence or clip to a Soundtrack Pro multitrack project. For
example, when the picture edit in a Final Cut Pro sequence is near completion, you simply
choose File > Send To > Soundtrack Pro Multitrack Project. Soundtrack Pro opens a new
multitrack project with the tracks, clips, and edits from the Final Cut Pro sequence,
including the synchronized video.
For information on sending Final Cut Pro sequences and clips to Soundtrack Pro, see
Using Soundtrack Pro with Final Cut Pro.

Setting Project Properties
Each project has a set of project properties that include sample rate, overlap mode,
selection mode, timecode, file management, and music-related properties. You can change
the project properties for a particular project using the multitrack project controls at the
top of the project pane or the Project tab.

Each project property has a default setting. You can also change the default project
properties for new projects in the Project pane of the Preferences window. For information
on setting preferences, see Setting Soundtrack Pro Preferences.

Sample Rate
The project sample rate determines the number of samples per second Soundtrack Pro
uses for audio playback and export. When you add audio files to your project, their sample
rate is matched (upsampled or downsampled) on the fly to the project sample rate with
no change to their pitch or file duration. The available sample rates are 32 kHz, 44.1 kHz,
48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. The default is 48 kHz, which is the
standard for digital video and DVD projects.
Note: When creating a soundtrack for a video, be sure you save and export your project
at the same sample rate the final video project will use.

• 176.4
• 192.0
Sample Rate pop-up
menu

Note: If you open your project on a computer that cannot support the project sample
rate, the project is resampled to the nearest rate the hardware supports for playback.
When you export your project, it is exported at the project sample rate, regardless of
hardware limitations. For more information on hardware sample rates, see Setting Up
Your System.

Overlap Mode
The project overlap mode determines what happens when you move an audio clip so
that it partially or completely overlaps another clip in the Timeline. There are two overlap
modes—crossfade mode and truncate mode.
In crossfade mode, when you drag an audio clip so that it partially overlaps another audio
clip in a track in the Timeline, a crossfade is created for the overlapped part of the two
audio files. You can adjust the boundaries of the crossfade in the Timeline. In truncate
mode, when you drag an audio clip so that it partially overlaps another audio clip in a
track in the Timeline, the overlapped part of the clip is truncated.

To set the project overlap mode
Click the Crossfade Mode button to set the project to crossfade mode, or click the Truncate
Mode button to set the project to truncate mode.

Press Option-E.
For more information about the envelope selection mode, see Selecting and Moving
Envelope Points with Clips.

Choosing the Project Time Format
Each multitrack project has a project time format, which can be either Time (seconds)-based
or Beats-based. Setting the time format controls the appearance of the Time display, Time
ruler, Timeline gridlines, and available Snap To values. For projects set to Time-based
format, time is displayed using the Time Ruler units chosen in the View menu. For projects
set to Beats-based format, the time is displayed in measures, beats, and beat divisions.
The default format is Time-based.
Setting the format to Time-based lets you align clips and other items in the Timeline with
specific points in time, for example, specific frames in a video file. Setting the format to
Beats-based lets you align items in the Timeline with measures, beats, and other musical
units of time, regardless of tempo. You can switch between Time-based and Beats-based
formats while working on a project. You can also set individual tracks to use a different
time format than the project’s time format. For information on setting a track’s time
format, see Changing Track Time Format.
Setting the Project Ruler Units
You can switch the ruler units for a project in the Project tab and define the details for
the ruler units in the View menu.

To choose the ruler units for a project
In the Project tab, use the Ruler Units pop-up menu to choose either Seconds or Beats.

Chapter 5 Working with Multitrack Projects

117

When you import a video file into a Soundtrack Pro project, the Time display and Time
ruler adjust to show the timecode format of the video. The Time display and Time ruler
can display time in seconds, frames, drop frames, or non-drop frames. You can choose
the format for timecode display, and you can set the video frame rate for projects not
containing a video file. You can also set the default frame rate for new projects in the
Project Preferences pane.
To specify the details of the units shown in the Time display and Time ruler
1 Choose View > Time Ruler Units, then choose one of the following time formats from the
submenu:
• HH:MM:SS
• Seconds
• Samples (Audio file projects only)
• Frames
• Drop frame (timecode)
• Non-drop frame (timecode)
2 If your project does not contain video, you can also specify the following settings:
• Set Video Frame Rate: Choose from the following: 23.98, 24, 25, 29.97, 30, 59.94, 60.
• Set Starting Timecode: Enter the timecode for the first frame of your project.
Time Ruler Units and Gridlines
The number of gridlines drawn will depend on the dominant ruler type and zoom level.
For example, when the dominant ruler is Seconds and the Timeline is zoomed out, gridlines
appear only on the hour marks. As you zoom in, gridlines are drawn on the minute mark.
Zoom in more, and gridlines are drawn on the second marks, and so on.

Setting the Project Length
By default, the length of a project depends on the media in the project. The project length
is set to the end of the last clip in the project. If the project uses a time-based effect, and
the effect extends past the end of the last clip, the project length extends to include the
effect’s “tail.” Adding a clip to the end of the project, or adding an effect that produces
a “tail,” extends the project length to include the new clip or the effect’s tail. You can
optionally set the project to a definite length.

118

Chapter 5 Working with Multitrack Projects

To set the project length
In the Timeline, place the playhead at the point where you want the project to end, then
choose Mark > Set End of Project.

End-of-project marker

You can move the end-of-project marker to change the length of the project, or delete
it if you decide you no longer want it in the project.

To delete the end-of-project marker
Select the marker in the Timeline, then choose Edit > Delete (or press the Delete key.)

Setting Default Locations for Saving Media Files
During the course of a large sound editing project, you may generate numerous project
files, clips, render files, and audio recordings. Soundtrack Pro helps you manage all this
media by saving the files to default scratch locations. You can change the scratch locations
using Soundtrack Pro preferences.

Edited Media Location
When Soundtrack Pro saves audio file projects created automatically in the multitrack
Timeline, the default location for those files is /Users/username/Documents/Soundtrack Pro
Documents/Edited Media/Multitrack Project Name/.
To change the edited media location
Do one of the following:

µ
µ

Choose Soundtrack Pro > Preferences > General, then click Choose to enter a new location.
In the Project tab, choose one of the following in the Create Media section:
• In Edited Media (from Preferences)
• In Media folder with project

Scratch Location
When Soundtrack Pro automatically creates audio file projects for edited media in the
multitrack Timeline, the default location for those files is
/Users/username/Documents/Soundtrack Pro Documents/Temporary Files/. These files
are moved to the Edited Media Location when the multitrack project is saved.

Chapter 5 Working with Multitrack Projects

119

To change the scratch location
Choose Soundtrack Pro > Preferences > General, then click Choose to enter a new location.

Recordings Location
When you record audio in the Soundtrack Pro multitrack Timeline, the default location
for those audio recordings is /Users/username/Documents/Soundtrack Pro
Documents/Recordings/.

To change the recordings location
Choose Soundtrack Pro > Preferences > Recording, then click Choose to enter a new
location.

Collecting Media for a Project
When you save a Soundtrack Pro multitrack project, you have the option to collect the
associated audio and video files in one folder, alongside the multitrack project. You can
make these choices at the time you save a project, or in the Project tab in the Project File
Management section. For more information on these options, see Saving Multitrack
Projects.

Saving Multitrack Projects
At any time while you are working, you can save your multitrack project.
To save your project
1 Choose File > Save.
2 In the dialog that appears, enter a name for the project in the Save As field.
3 Navigate to the folder in which you want to save the project.
4 Select any of the following checkboxes:
• Save Compacted: Saves the project without display data, which can save disk space,
but the project may take longer to open.
• Collect Audio Files: Saves a copy of every audio file the project uses to the selected
location. This makes it easy to move projects between computers, and ensures that all
needed audio files are available for playback. When you select this checkbox, the setting
is retained for any subsequent saves. In other words, the File > Save menu option
changes to File > Save (Collected), and any new media you add to the project is collected
the next time you save the project.
Note: To play a project on another computer, you must install the audio files the project
uses on that computer, or on a disk it can access. If you remove the audio files used in
a project so that your computer cannot access them, missing files will not play.

120

Chapter 5 Working with Multitrack Projects

• Collect Unused Audio Files: Includes media files you have deleted from the project but
that remain in the Bin. If you do not want to include these media files, deselect this
checkbox.
Note: Optionally, you can open the Bin, select the audio files you want to remove, then
choose Remove Unused from the Media pop-up menu.
• Collect Video File: Saves the project’s video file in the same folder as the project.
• Save Edited Media Locally: Saves the project’s edited audio files in the same folder as
the project (in a subfolder named Media). If this checkbox is not selected, edited media
is saved to the edited media location defined in Soundtrack Pro preferences.
Note: Multitrack projects are saved as documents with the extension.stmp.
5 You can optionally click the New Folder button to create a new folder for the collected
project.
6 Click Save to save the project.
If the folder already contains any of the media files, an alert appears, asking if you want
to replace the existing files.
Note: Because video files can be very large, if you save a multitrack project collected (by
selecting the Collect Audio Files or Collect Video File checkbox in the Save As dialog), it
may take several minutes and may require a large amount of disk space to save the
project.

Adding Files to a Multitrack Project
Once you’ve located and previewed an audio file you want to add, you drag the file to
the Timeline to add it to the project. When you drag an audio file to the Timeline,
Soundtrack Pro creates an audio clip from the audio file and adds the clip to the project.
An audio clip does not contain the actual audio data; instead, it contains a reference to
the file stored on disk. Editing an audio clip in the Timeline does not change the source
audio file.
To add an audio file from the media tabs
Do one of the following:

µ
µ

Drag the file from one of the media tabs to a track in the Timeline.
Drag the file from the File list to the strip between two existing tracks.
A new track is created and the clip is added to the track.

Drag the file from the File list to the empty part of the Timeline below the Master bus.
A new track is created and the clip is added to the track.

To add an audio file from the Finder
Drag the file from the Finder to the Timeline (to a track, between two existing tracks, or
to the area below all existing tracks).
When the Bin tab is active, the Bin shows all of the audio clips in the project. You can
drag a clip from the list to the Timeline to add a new clip from the same audio file at a
different point in time, or to a different track.

To add an audio file from the Bin tab
Drag the file from the Bin tab to the Timeline, either to a track or to the area below the
existing tracks.
Note: When you drag an audio file to the Timeline, the file snaps to the nearest Snap To
position if snapping is turned on. For information on setting the Snap To value, see Using
Snapping.

122

Chapter 5 Working with Multitrack Projects

Clip Properties
When you create an audio clip by dragging an audio file to the Timeline, the audio clip
has a set of properties. These properties are specific to the clip and can be different for
two clips created from the same source audio file. Properties for a selected clip are
displayed and can be edited in the Details tab. For more information, see Details Tab.

Some properties can be changed by editing the clip in the Timeline. For detailed
information on editing audio clips, see Selecting Audio Clips in the Timeline. Other clip
properties, such as color, can be applied to clips directly. For more information, see Editing
Clip and Track Properties.
The name of an audio clip appears on the clip in the Timeline. By default, the entire name
appears on the clip if the clip is long enough to display it. You can change the default
behavior in the General pane of the Preferences window, so that long clip names are
truncated from the center. For information on setting preferences, see Setting
Soundtrack Pro Preferences.

Chapter 5 Working with Multitrack Projects

Tracks, Busses, Submixes, and the Master Bus
Multitrack projects contain tracks, busses, and submixes. Tracks, busses, and submixes
appear as horizontal rows in the Timeline and as vertical channel strips in the Mixer. In
both the Timeline and Mixer, tracks, busses, and submixes are grouped together, with a
separator between each category. You can move each type within its own category but
cannot move it to either of the other categories. Each track, bus, and submix has a header
with its icon, name, and a set of controls. The Master bus represents the final mix that
goes to physical outputs. The Master bus has no icon or editable name.

Tracks
Tracks contain the audio you add to your project in the Timeline. Each track has a color
label, a name, an icon, and a set of controls that appear in the track’s header in the Timeline
and in its channel strip in the Mixer. Track controls include a volume slider, a pan control,
a submix pop-up menu, and buttons to mute or solo the track, bypass effects, and enable
the track for recording. In addition, each channel strip includes level meters you can use
to watch the track’s levels and a set of effects slots where you can add and order track
effects and sends.

Busses
In Soundtrack Pro, a bus is a separate but parallel audio signal created with a send. A send
can tap an audio signal and create a separate signal known as a bus. (Some might call
this an auxiliary bus.) Busses can be processed or combined independently of the main
signal. They can be combined with other signals in a submix or at the final mix, or they
can be routed to altogether separate outputs.

Volume fader

Each bus has a color label, a name, an icon, and a set of controls that appear in the bus’s
header in the Timeline and in its channel strip in the Mixer. Bus controls are the same as
track controls, except that a bus does not have an Arm for Recording button (because
you can’t record audio to a bus). The bus controls affect the audio of every track sent
(routed) to that bus.

124

Chapter 5 Working with Multitrack Projects

For example, you could route every dialogue track for a particular actor to a bus with the
actor’s name. You could adjust the volume of all the actor’s dialogue using the bus volume
fader and add an EQ effect that brings out the actor’s voice in the mix. You could then
route that audio bus to a particular submix. The main reason to apply effects this way
(rather than directly on the track) is so you can control the amount and characteristics of
the effect on multiple tracks using one set of controls.
For more information about using busses and sends, see Using Sends and Busses.

Submixes
Submixes let you combine the audio from different tracks and busses and route the audio
to physical outputs. If you are using external audio hardware that supports multiple
physical outputs, you can add submixes to a project and choose the physical output to
which each submix routes its audio. For more information about signal routing in
Soundtrack Pro, see Basic Signal Routing in Soundtrack Pro.
For example, you could route the audio from the dialogue tracks for each actor to a
submix called “Dialogue” and then route all of the dialogue from that submix to a single
output jack. You could route all music tracks to another submix and all effects tracks to
a third submix. Then you could adjust the volume or add effects separately to each submix.
For a final stereo mix, you could route all submixes to the same pair of physical output
channels (channels 1 and 2, for example), or to separate outputs. In the case of a surround
mix, you could route all submixes to channels 1–6. For a detailed explanation of this
example, see Example: Mixing a Project with Submixes.

Chapter 5 Working with Multitrack Projects

125

Each submix has a color label, a name, an icon, and a set of controls that appear in the
submix’s header in the Timeline and in its channel strip in the Mixer. Submix controls
include a volume slider, a pop-up menu where you can choose the physical output
channels for the submix, and buttons to mute or solo the submix and add effects. Each
submix channel strip includes level meters you can use to watch the submix’s levels and
a set of effects slots where you can add and order effects and sends. Submixes do not
have pan controls or Arm for Recording buttons.

Chapter 5 Working with Multitrack Projects

The Master Bus
The Master bus represents the final mix from Soundtrack Pro: what will be heard from
physical output jacks. On a signal routing basis, the Master bus is practically a mirror
image of the connected hardware output device. It has a single volume control but does
not have panners. You can apply effects to the Master bus, but you cannot automate
those effects. Effects applied to the Master bus are placed across all channels.
For more information about the Master bus, see Using the Master Bus.

Working in the Timeline

The Timeline is where you arrange audio clips to build your soundtrack. You can also
adjust volume and panning, add effects, and edit envelopes to control automation. You
can select, cut, copy, and paste clips, move, resize, transpose, split and join them, and
edit them in other ways.
This chapter covers the mechanics of working with clips, tracks, busses, and submixes in
the Timeline.

About the Timeline
The Timeline displays a visual representation of a project, showing the point in time when
audio clips start playing and their duration. You control when and how long clips play
by moving and resizing them in the Timeline.
The Timeline also displays vertical gridlines that make it easy to position clips precisely
in time. The gridlines correspond to the divisions of time in the Time ruler. The units of
time the gridlines display change depending on the Ruler Units setting in the Project tab
and the current zoom level. The Timeline is arranged in three sets of horizontal
rows—tracks, busses, and submixes. You add audio clips to tracks, create submixes using
busses, and send audio to physical output devices using submixes. For information about
working with tracks, busses, and submixes, see Tracks, Busses, Submixes, and the Master
Bus.

Using the Timeline Editing Tools
The Timeline includes editing tools you can use to edit and adjust clips in the Timeline.

130

Chapter 6 Working in the Timeline

Selection Tool
When you open the Timeline, the pointer is a selection pointer (arrow). You can use the
Selection tool to select clips and tracks by clicking them and use it to make marquee
selections across multiple tracks. When you are done using another Timeline editing tool,
you can return the pointer to a selection pointer by clicking the Selection Tool button or
by pressing A.

Selection tool

Timeslice Tool
You can use the Timeslice tool to make time-based selections. Timeslice tool selections
are entirely time-based, so you can use the Timeslice tool to select portions of clips or
portions of multiple clips. (This is unlike selections across multiple tracks with the default
Selection tool, which can only select whole clips.) Timeslice selections in the Timeline will
also appear as selections in the File Editor tab. You can select the Timeslice tool by pressing
W. For more information about the Timeslice tool, see Editing with the Timeslice Tool.

Timeslice tool

Blade and Blade All Tools
Using the Blade tool, you can perform many splits consecutively without moving the
playhead each time. Use the Blade All tool to split across all tracks. You can select the
Blade tool by pressing B, and the Blade All tool by pressing BB. For more information
about the Blade and Blade All tools, see Splitting and Joining Audio Clips.

Lift and Stamp Tools
The Lift and Stamp tools provide an efficient way to transfer properties from one clip to
one or more other clips. Use the Lift tool to copy properties from selected clips and create
a processing template in the Sound Palette that can be applied to other clips. Use the
Stamp tool to apply those properties to the other clips. You can select the Lift tool by
pressing UU, and the Stamp tool by pressing U. For more information about the Lift and
Stamp tools, see The Lift and Stamp Tools and the Sound Palette.

Scrub Tool
The Soundtrack Pro Scrub tool provides detailed scrubbing that realistically approximates
the “rock-the-reels” scrubbing on analog tape decks. You can select the Scrub tool by
pressing H. For more information about the Scrub tool, see Scrubbing Audio Files.

Scrub tool

Timeline Editing Tools HUD
The Timeline includes a handy HUD that provides all of the graphical Timeline editing
tools at the stroke of a single keyboard shortcut. This saves you the time and effort of
having to move the pointer up to the top of the Timeline whenever you need to select
(or deselect) a Timeline editing tool.
To use the Timeline Editing Tools HUD
1 Press the grave accent key (`).
The Timeline Editing Tools HUD appears at the pointer location.

2 In the HUD, do one of the following to choose the Timeline editing tool that you want
to use:
• Click the tool’s icon.
• Press the corresponding number key (1–7, left to right).
• Use the Left Arrow and Right Arrow keys and press Enter.

Chapter 6 Working in the Timeline

When you have finished using a Timeline editing tool, it is a good idea to immediately
return to the default Selection tool.

Moving Around in the Timeline
Soundtrack Pro provides several controls that let you change the view of the Timeline
and move to different parts of your project. You can zoom in or out for a closer or wider
view of the Timeline, control how many tracks are displayed in the Timeline, create an
area in the Timeline that plays back repeatedly, and change which part of the project is
currently visible using the scroll bars and project controls. You can split the Timeline view
and use the Global Timeline view to quickly move to different parts of your project.

Using the Scroll Bars
If the entire project cannot be displayed in the Timeline, you can scroll through the project
using the horizontal scroll bar located at the bottom of the Timeline. Drag the horizontal
scroll bar left or right to move the visible part of the Timeline.
If your project contains more tracks than can be displayed in the Timeline, a vertical scroll
bar appears along the right edge of the Timeline. Drag the vertical scroll bar up or down
to change which tracks are visible.

In the lower left of the project pane are the Timeline controls, including the Track Height
control and Zoom control.

Using the Zoom Control
You can zoom in to make precise edits in the Timeline, or zoom out for a wider view of
your project using the Zoom control.

Chapter 6 Working in the Timeline

The Zoom control features a slider on a graduated scale. Moving the slider to the left or
clicking the left side of the control zooms in for a closer view, displaying a smaller area
of the Timeline close up. Moving the slider to the right or clicking the right side of the
control zooms out for a wider view, displaying a wider area of the Timeline.

time the gridlines display change depending on the Ruler Units setting in the Project tab
and the current zoom level.
For a complete list of keyboard shortcuts, see Soundtrack Pro Keyboard Shortcuts.

Using Multi-Track Gestures to Control Playback
If your portable computer has a Multi-Touch trackpad, you can use the rotate gesture to
play back audio in the Timeline. The speed of playback is determined by the speed of
the rotate gesture. For example, a very slow clockwise rotate gesture scrubs the audio
forward from the position of the playhead. For more information on scrubbing audio,
see Scrubbing Audio Files.

To move the playhead to the right
Use the rotate gesture clockwise.

To move the playhead to the left
Use the rotate gesture counterclockwise.

Setting Track Height
You set the height of tracks, busses, and submixes in the Timeline using the Track Height
control. The Track Height control has four settings. The smallest rectangle sets the track
height to a minimized setting, with each track (and track header) reduced to half-height,
allowing more tracks to be displayed in the Timeline.
To set the height of tracks, busses, and submixes
Do one of the following:

Note: Track header controls for setting up recording appear in the two tallest track heights
only.

Using the Global Timeline View
The Global Timeline view, located above the Time display and Time ruler, shows a
miniature view of the entire project. The playhead appears as a black vertical line with a
triangular handle. The part of the project currently visible in the Timeline is indicated by
a blue rectangle in the Global Timeline view.

To move to a new area of the Timeline using the Global Timeline view
Drag the visible area rectangle to a new position.
Drag this rectangle
to a new position.

You can quickly move to different parts of the Timeline by dragging the blue rectangle.
This is especially useful when working on longer projects. You can also drag the rectangle
up or down to move vertically in the Global Timeline view. This is useful if your project
contains more tracks, busses, and submixes than can be displayed in the project pane.

Using the Time Ruler
The Timeline has a Time ruler that shows the divisions of time in a project. You can set
the playhead to a precise frame, point in time, or sample number using the Time-based
units on the Time ruler, or to a specific musical measure or beat using the Beats-based
units, to synchronize playback of audio clips in the Timeline.
The Time ruler changes depending on the time format of the project and the Time ruler
units. If the project is currently set to Time-based format, Time-based units appear in the
upper part of the ruler. If the project is set to Beats-based format, Beats-based units appear
in the upper half of the ruler.

You can use the Time ruler to position clips or the playhead at a precise point in time,
including synchronizing them to a specific timecode reference in a video file.

To set the playhead to a specific point in the Time ruler
Click the Time ruler at the point where you want to set the playhead.

Working with the Cycle Region
You can create a cycle region in a project, an area that plays back repeatedly. This is
sometimes called cycling or looping playback. A project has only one cycle region, but
you can move and resize it as often as you want. Additionally, for selecting, marking, and
exporting purposes, the cycle region functions much like In and Out points in Final Cut Pro.

138

Chapter 6 Working in the Timeline

You also use the cycle region when recording multiple takes. For information on recording,
see Recording Audio in Soundtrack Pro.
To set the cycle region
Do one of the following:

Drag in the Time ruler from the beginning of where you want the cycle region to the end.

Drag in the Time ruler
to set the cycle region.

Position the playhead and press I to set the cycle region In point. Position the playhead
and press O to set the cycle region Out point.

Press X to set the cycle region In and Out points at the boundaries of the clip that currently
intersects the playhead. The clip on the uppermost track is used.
Note: For a complete list of keyboard shortcuts, see Soundtrack Pro Keyboard Shortcuts.
The cycle region is lighter in color than the rest of the Time ruler, with triangular markers
indicating its start and end points. If a cycle region already exists, you can drag anywhere
in the Time ruler outside of the current cycle region to set the cycle region to a new
position.
If cycling is turned off, you must turn it on for the cycle region to be active. The Cycle
button darkens to indicate that the cycle region is activated.
To activate or deactivate the cycle region
Do one of the following:

µ

139

Working with Tracks, Busses, and Submixes in the Timeline
The Timeline is arranged sets of horizontal rows—tracks, busses, and submixes. You add
audio to tracks in your project, use busses to create effect sends, and route audio to
physical output channels using submixes.
The tracks in a project appear in the upper part of the Timeline. Busses appear below
tracks, and submixes appear below busses. The Master bus appears below submixes. The
Master bus represents the final mix that will be heard from physical output jacks. It has
a single volume control and no panners or meters. You can apply effects to the Master
bus.
A separator between each set of Timeline rows helps visually distinguish them, and
disclosure triangles on each separator let you show or hide the different sets. Tracks,
busses, and submixes in the Timeline correspond to channel strips in the Mixer. When
you add a track, bus, or submix, adjust its controls, or add effects, the same changes
appear in the corresponding channel strip when you open the Mixer.
Tracks, busses, and submixes are described in greater detail in Tracks, Busses, Submixes,
and the Master Bus.

Adding Tracks, Busses, and Submixes
There are several ways to add tracks, busses, and submixes.
To add a track

Grouping Tracks, Busses, and Submixes
You can create groups of tracks, groups of busses, and groups of submixes. Groups provide
a way to easily select and make changes (such as volume, mute, solo, and lock adjustments)
to many tracks, busses, or submixes at once. When Mixer objects are grouped, selecting
one item in the group selects all items in that group.
Note: It is not possible to group Mixer objects from different categories. For example,
you cannot group tracks with busses or tracks with submixes.
To group tracks, busses, or submixes

Managing Track Selections with the Tracks Tab
The Soundtrack Pro Tracks tab is a convenient tool for selecting and grouping tracks,
busses, and submixes. The Tracks tab consists of three sections: the Mixer Objects outline,
the Groups outline, and a channel strip for the currently selected item.

Mixer Objects Outline
The upper left of the Tracks tab displays an outline view of the Timeline, including all
tracks, busses, and submixes. Use this outline to quickly manage, select, and group Mixer
objects (track, bus, or submix) without having to view the entire Timeline.

To select an individual Mixer object (track, bus, or submix) in the Tracks tab
Click the track, bus, or submix in the Mixer Objects outline.
You can also use the Up Arrow and Down Arrow keys to navigate through individual
Mixer objects.

Channel Strip
The right side of the Tracks tab displays a single channel strip for the currently selected
track, bus, or submix. (This channel strip is identical to the corresponding channel strip
in the Mixer in every way, including all controls and current settings.) It is a quick way to
access the mixing controls for a particular Mixer object.

Note: The channel strip is displayed only if a single track, bus, or submix is selected.
For more information about channel strips, see Using the Mixer.

Moving and Copying Tracks, Busses, and Submixes
As you work on your project, you may want to rearrange tracks, busses, and submixes.
You can move and copy them to change their vertical arrangement in the track, bus, or
submix section of the Timeline. You cannot move one to the area for another (as indicated
by the rows labeled “Tracks,” “Busses,” “Submixes,” and “Master” in the Timeline).
You can only move or copy one track, bus, or submix at a time.

To move a track, bus, or submix
Drag the track, bus, or submix header up or down to a new vertical position.

A copy of the track, bus, or submix appears when you release the mouse button.

Renaming Tracks, Busses, and Submixes
By default, tracks are numbered when created and take the name of the first audio clip
you add to them. Busses and submixes are numbered starting from 1 (Bus 1, Submix 1,
and so on). You can rename a track, bus, or submix and use the names to distinguish the
type of audio it contains (for example, dialogue, voiceovers, music, or sound effects), its
part in the overall project, or to identify it in some other way.

To rename a track, bus, or submix
Click the name field in the header for the track, bus, or submix and type a new name.
Note: You cannot rename the Master bus.

Muting and Soloing Tracks, Busses, and Submixes
The Mute button mutes (silences) the track, bus, or submix. You can mute multiple tracks,
busses, and submixes, which allows you to hear only the remaining, unmuted ones.
Muting lets you compare the sound of the project using different combinations of tracks,
busses, and submixes, and hear the result of changes you make to them.
The Solo button solos the track, bus, or submix, muting all others. Soloing a track, bus, or
submix lets you quickly isolate it from the rest of the project, so you can adjust the sound
of the soloed track, bus, or submix and make changes.
Soundtrack Pro supports multiple solo and exclusive solo. Clicking the Solo button for
multiple tracks, busses, or submixes solos them and mutes all others. When you exclusively
solo a track, bus, or submix, all others are muted, regardless of whether they are soloed.

Changing Track Time Format
By default, tracks use the same time format as the project (Time-based or Beats-based).
You can change the time format of a track, which changes the behavior of tagged clips
when you change the project tempo.
When the track time format is Time-based, clips remain at the same time position (the
same second or frame) when you change the project tempo. When the track time format
is Beats-based, clips remain at the same beat position (the same measure, beat, and beat
division) when you change the project tempo.
When you set a track to Beats-based time format, a metronome appears in the corner of
the track icon.
To change a track’s time format
1 Select the track.

them to close a gap or to create space to accommodate new clips in your project. After
selecting a track’s contents, you can perform different operations on all the track’s items
at once, such as moving, copying, or deleting them. This feature also works with multiple
tracks.
To select all the clips on selected tracks
1 Select one or more tracks.

Chapter 6 Working in the Timeline

153

For more information on selecting tracks, see Selecting Tracks, Busses, and Submixes.
2 Choose Edit > Select > Across Tracks (or press Shift-T).
All clips in the track are selected.
If you make this selection in Selection tool mode, all clips on currently selected tracks are
selected. Any clips that were selected before choosing the menu item are included in the
new selection.
Note: Double-clicking a track in Selection tool mode selects all clips in that track. Any
previously selected clips are not included in the new selection. Triple-clicking a track
selects all clips in the Timeline.
If you make this selection in Timeslice tool mode, any existing Timeslice selection is
extended horizontally to cover the entire duration of the project. If there is no existing
Timeslice, Soundtrack Pro creates a Timeslice across the entire length of all selected tracks
(or all tracks if none are selected).
Note: Double-clicking a track in Timeslice tool mode creates a timeslice over the
double-clicked area (either a clip or the gap between two clips). Triple-clicking a track
creates a Timeslice across the entire track.

Selecting Partial Contents of One or More Tracks
When there are many clips in a multitrack project, it’s difficult to see and select many of
them at once, especially if you don’t want to zoom in and out frequently. The Select
Forward and Select Backward commands let you easily select all clips before or after the
playhead.
To select all the clips to the right or the left of the playhead on selected tracks
1 Make sure no clips are selected by clicking in the Timeline in a space between clips.
2 Select one or more tracks.

the playhead
are selected.

If you make this selection in Selection tool mode, all clips to the right (Forward) or left
(Backward) of the playhead in the selected tracks are selected. Any clips that were selected
before choosing the menu item are included in the new selection.
If you make this selection in Timeslice tool mode, any existing Timeslice selection is
extended to the end of the project (for the Forward option) and to the beginning of the
project (for the Backward option). If there is not an existing Timeslice, Soundtrack Pro
creates a Timeslice across selected tracks starting at the playhead and extending to the
end of the project (for the Forward option) and to the beginning of the project (for the
Backward option).
Note: If you hold down the Option key, the menu items read Select > All Forward and
Select > All Backward and behave the same as described above except the selection is
across all tracks instead of just the selected tracks.

Cutting, Copying, Pasting, and Removing Audio Clips
You can cut, copy, paste, and remove audio clips in the Timeline. You can also paste
multiple copies of a clip.

To cut an audio clip
Select the clip in the Timeline, then choose Edit > Cut (or press Command-X).

The clip is pasted in the currently selected track, starting at the current playhead position.
If no track is selected, the clip is pasted in the track from which it was cut or copied.
When pasting clips cut or copied from different positions in the Timeline or from multiple
tracks, the following conditions apply:
• Pasting clips from different Timeline positions: The clip closest to the beginning of the
project is pasted at the current playhead position, and the remaining clips are pasted
at the same positions in time relative to the first clip as when they were cut or copied.
• Pasting clips from multiple tracks: The clip from the topmost track is pasted in the
currently selected track, and the remaining clips are pasted at the same positions relative
to the first clip as when they were cut or copied. If there are not enough tracks to
accommodate the clips being pasted, a dialog appears asking if you want to create
new tracks for the clips. If you choose not to create new tracks, only the clips for which
tracks already exist are pasted.
When pasting audio clips, you can choose to paste multiple copies of the clip in succession.
Using the Paste Repeat command, you can paste any number of copies of a clip in the
selected track.

To paste multiple copies of a clip

Note: Holding down the Command key while trimming or moving a clip toggles the
current snapping state.

To move an audio clip to a new track
Drag the clip up or down to a different track.
You can also move an audio clip using the Left Arrow and Right Arrow keys with various
modifier keys. Using the Command key with the arrow keys moves the clip the default
nudge amount; using the Command and Shift keys with the arrow keys moves the clip
to the next gridline in the Timeline.
You can lock the horizontal (time) position of an audio clip when moving the clip between
tracks in the Timeline. This makes it easy to keep the clip’s start point when moving the
clip or copying it by Option-dragging.
If the Timeline is in Select Only Clips mode, envelope points are not moved along with
clips. If you wish to move envelope points and clips together, the Timeline must be in
Select Envelope Points With Clips mode. For more information, see Selecting and Moving
Envelope Points with Clips.

To lock the time position of a clip as you move it between tracks
Hold down the Shift key while dragging the clip up or down to a different track.

Moving Clips Numerically
When you want to move clips precisely, you can move them by entering positive or
negative timecode values.
To move an item by entering a timecode value
1 In the Timeline, select the clip item or items you want to move.
2 Type a relative timecode value for where you want the clip to be positioned.
For example, type +48 (or simply 48) to move the item 48 frames forward. To move
48 frames backward in time, type -48. When you type a number, a Move field appears at
the top of the Timeline.
Note: Don’t click in the Current Timecode field before you do this, or you’ll move the
playhead instead.

Moving Clips with Keyboard Shortcuts
Soundtrack Pro provides a variety of keyboard shortcuts to move selected clips. For more

Snapping Clips to Clips on Other Tracks
If Snap To is set to All Edits, you can snap a clip to the edges of a clip in any other track.
This is especially useful when the start and end points of clips do not fall on the current
Snap To value.

To snap a clip to a clip on another track
Choose View > Snap To > All Edits.

Resizing Audio Clips
You control the duration of an audio clip (the amount of time the clip plays back) by
resizing the clip. When you add a clip to the Timeline, the clip has the same duration as
the source audio file.
You can shorten clips to play back only a part of the source file. When you resize a clip
by shortening its left edge, you change the point in the source audio file at which the
clip starts playing, making the earlier part of the source audio inaudible. When you resize
a clip by shortening its right edge, the part you shorten becomes inaudible. You cannot
lengthen the left edge of a clip with non-looping playback mode beyond the beginning
of the source audio file.
When you lengthen a regular, non-looping clip beyond its original length, Soundtrack Pro
adds blank space at the end of the clip.
A blank space appears
when a non-looping clip
is lengthened beyond
its original length.

When you lengthen a looping clip, it repeats the source file multiple times. The notches
at the top and bottom of the clip indicate the end of each repetition of the source audio
file.
Drag the clip to the left
or right to resize it.
Notches indicate the
points where a looping
clip repeats.

To resize an audio clip
1 Place the pointer at either the left or right edge of the audio clip.
The pointer changes to a Clip Resize pointer.

Chapter 6 Working in the Timeline

163

2 Click the edge of the clip and drag left or right to resize it.
Note: Holding down the Command key while trimming or moving a clip toggles the
current snapping state.
When you resize a clip, the edge being resized jumps to the nearest Snap To position if
snapping is turned on. If you want to resize the clip independently of the Snap To value,
change the Snap To value or turn off snapping before you resize the clip. For information
about snapping, see Using Snapping.
To resize an audio clip to the boundaries of adjacent clips
1 Place the pointer at either the left or right edge of the audio clip.
The pointer changes to a Clip Resize pointer.
2 Click the edge of the clip.
3 Hold down the Shift key and drag left or right to resize the clip.
Resizing clips is limited to the boundaries of adjacent clips.

Using the Trim Command
Soundtrack Pro lets you adjust the In and Out points of clips in the multitrack Timeline
using the Trim command. You can either trim the In point of a clip to the playhead or

Changing the Offset of an Audio Clip
When you add an audio clip to the Timeline, the clip plays back from the beginning of
the source audio file. The point in the audio file where the clip starts playing is called the
offset. By default, a clip’s offset is zero, the beginning of the source audio file. You can
change the offset so that the clip starts playing from a later point in the source audio file.
(In Final Cut Pro, this is known as a slip.) This allows you to use the audio from a later part
of the source file without splitting the clip.

166

Chapter 6 Working in the Timeline

To slip (change the offset of) a clip
Select the clip, then Command-Option-drag left (toward the beginning of the project).

Command-Option-drag
left to change the
clip’s offset.

The waveform moves
inside the clip’s
boundary to indicate
the change in offset.

Once you have changed the offset by dragging to the left, you can also drag to the right
to change the offset.
Note: You can only drag the offset to a later part of the clip’s source audio file, not to a
point before the beginning of the file.
When you change the offset of a clip, the waveform moves inside the clip’s boundary to
indicate the change in offset. The length of the clip stays the same. If you slip past the
end of the media, looping files repeat and non-looping files play silence. For looping
clips, notches appear to show the point at which the clip starts looping.

Creating Fades and Crossfades in the Timeline
One of the most common tasks of a sound editor is adding fade-ins and fade-outs to
individual clips and crossfades between clips to smooth the overall sound of a video or
motion picture soundtrack.
Tip: Fades and crossfades can be applied using keyboard shortcuts. For more information,
see Soundtrack Pro Keyboard Shortcuts.

Types of Fade-Ins and Fade-Outs
This list describes the different types of fade-ins. The reverse behavior is true for fade-outs
in the logarithmic and exponential cases.

Chapter 6 Working in the Timeline

167

Note: The default fade type is +3 dB. Choose Soundtrack Pro > Preferences > Project to
change the default fade type.
Logarithmic
Linear

S-curve
Exponential

• Linear: The rate of attenuation stays constant over the length of the fade.
• Logarithmic: Starts quickly, then slowly tapers off toward the end.
• Exponential: Starts slowly, then moves quickly toward the end.
• S-curve: Eases in and out of the fade, with the midpoint at 0 dB.

Creating Fade-Ins and Fade-Outs in the Timeline
Soundtrack Pro lets you easily add fades and crossfades and adjust the fade type directly
in the multitrack Timeline.
To create a fade-in or fade-out on a clip in the Timeline
1 Move the pointer Over the top-left edge of the clip (for a fade-in) or top-right edge of
the clip (for a fade-out).
The pointer becomes a fade pointer.

Creating Crossfades Between Audio Clips
Crossfades let you create smooth transitions between one audio clip and the next and
avoid clicks or sudden changes in loudness that can result when placing audio files one
after another.
One of the ways to create a crossfade between audio clips is to use the Timeslice tool to
select a timeslice, then use the crossfade command. Another way is to set the project to
crossfade mode, then drag an audio clip so that it overlaps another clip. A crossfade is
created for the length of the overlapped area.
To use the crossfade command
1 Choose the Timeslice tool (or press W).

Chapter 6 Working in the Timeline

171

2 Select a timeslice overlapping two clips in the Timeline.

3 Choose Clip > Crossfade (or press Command–F).
The crossfade appears in the area selected by the Timeslice tool.
Note: This command works whether your multitrack project is set to crossfade mode or
truncate mode.

To set the project to crossfade mode
Click the Crossfade Mode button, located above the Global Timeline view.
Crossfade Mode button

In crossfade mode, when you drag an audio clip so that it partially overlaps another audio
clip in a track in the Timeline, a crossfade is created for the overlapped part of the two
audio files. You can adjust the boundaries of the crossfade in the Timeline.

To create a crossfade
In the Timeline, drag an audio clip so that it overlaps another audio clip.
The crossfade appears in the overlapped area of the two clips.
Crossfade

As with other edits you make in the Timeline, creating a crossfade between two audio
clips does not change the source audio files.
You can adjust crossfades in several ways. You can change the edges of the crossfaded
clips or move the position of the crossfade without changing its length.
To adjust crossfade boundaries
1 Move the pointer over the left or right edge of the crossfade.
The pointer becomes a crossfade pointer.
2 Drag the edge of the crossfade to adjust the crossfade boundary.

left clip.
The crossfade in the Timeline is updated to reflect your choice of fade type.

3 Click one of the four buttons in the column on the right to select a fade-in type for the
right clip.
The crossfade in the Timeline is updated to reflect your choice of fade type.

Truncating Overlapping Audio Clips
You can have Soundtrack Pro truncate the overlapping part of audio clips in the Timeline
instead of crossfading them. To truncate audio clips, you set the project to truncate mode,
then drag an audio clip so that it overlaps another clip.

To set the project to truncate mode
Click the Overlap Mode button, located above the Global Timeline view.
In truncate mode, when you drag an audio clip so that it partially overlaps another audio
clip in a track in the Timeline, the overlapped part of the clip is truncated.

To truncate an audio clip
In the Timeline, drag another audio clip over part of the clip.

Working with Markers
Markers have a variety of uses in the Timeline and the File Editor. For example, you can
use markers to:
• Mark the start and end points of major sections in your project
• Indicate places you want to come back to and work on later
• Mark points where you want to synchronize the audio with the picture in a video
• Indicate where particular sounds begin and end in an audio file
Markers extend vertically through the Timeline, like the playhead. Each marker has a
handle in the area above the Time ruler, letting you position the marker precisely in the
Timeline.

Types of Markers
Soundtrack Pro displays Final Cut Pro scoring markers and lets you add your own markers
to a project. You can add two kinds of markers: time markers and beat markers. The two
types can be distinguished by their handles: time markers have green handles, and beat
markers have purple handles. Final Cut Pro scoring markers have orange handles. By
default, time and beat markers can only occupy a single frame of time, but their duration
can be extended to any length.
The following sections discuss how to work with time markers and beat markers in a
project. For information about working with Final Cut Pro scoring markers, see Using
Final Cut Pro Scoring Markers.
Time marker (green)

Beat marker (purple)

End-of-project

Inserting Markers
You can insert a beat marker or time marker at any point in the Timeline.

174

Chapter 6 Working in the Timeline

To insert a time marker
Set the playhead to the point where you want to add the marker, then choose Project >
Insert Time Marker (or press the M key).

To insert a beat marker
Set the playhead to the point where you want to add the marker, then choose Project >
Insert Beat Marker (or press Option-B).

Naming Markers
You can name time markers and beat markers, so that each marker can provide a unique
visual cue to a specific point in the Timeline or File Editor. For example, you can name
markers to define sections of your project (Introduction, Verse, or Chorus), to reflect what’s
happening in the music (Latin Rhythm or Fast Groove), or to serve as reminders for your
workflow (Add Horns Here, Transpose to D, Insert Delay Effect).

To name a time marker or beat marker
Make the Details tab active, select the marker, then type a name in the Name field of the
Details tab.

Type a name in the
Marker Name field.
Enter a time position
here to move the
marker to that position.

To view marker titles in the Timeline
Choose View > Show Marker Titles.

Moving Markers
You can move a marker either by dragging the marker’s handle or by entering a new
position for the marker in the Details tab.
To move either a beat marker or time marker
Do one of the following:

Drag the marker by its handle, located in the area above the Time ruler, to a new position
in the Timeline.

Show the Details tab, click the marker you want to move, then enter a new position in
the Position field.

Chapter 6 Working in the Timeline

175

Note: You can also select and drag multiple markers. When you move a marker by
dragging, the marker’s position snaps to the nearest Snap To position if snap is turned
on. For information on setting the Snap To value, see Creating Fades and Crossfades in
the Timeline.

Adjusting a Marker’s Duration
By default, Time markers and Beat markers have a duration of zero, but you can create
Time or Beat region markers by changing the duration of any marker. You adjust a marker’s
duration either by entering a new duration for the marker in the Details tab, or, if it is
already a region marker, by dragging the ends of a marker handle.
To adjust a marker’s duration
Do one of the following:

Show the Details tab, click the marker you want to adjust, then enter a new duration in
the Duration field.

Adjust a region marker by dragging the end of its handle.

Deleting Markers
If you decide you don’t want a time or beat marker that you’ve added, you can delete it
at any time.

To delete a marker
Click the marker handle to select the marker, then choose Edit > Delete (or press Delete).
Note: You cannot delete Final Cut Pro scoring markers in Soundtrack Pro.

Using Markers with Video
Soundtrack Pro displays Final Cut Pro scoring markers included in a video file imported
from Final Cut Pro. You can add time markers at points in time corresponding to specific
timecode positions in the video clip, and align audio clips with markers using the snapping
feature. When you add a marker to a project containing a video, the video clip displays
the frame of the video that occurs at the marker’s position in time.
For more information about adding and moving markers, see Working with Markers.
You can score both Final Cut Pro scoring markers and time markers to the playhead,
letting you synchronize the audio with specific points in the video.

176

Chapter 6 Working in the Timeline

Using Final Cut Pro Scoring Markers
When you import a video file from Final Cut Pro or Final Cut Express HD, Soundtrack Pro
displays any Final Cut Pro scoring markers included in the video file in the Timeline.
Scoring markers have an orange handle in the area above the Time ruler. You cannot
move or edit Final Cut Pro scoring markers in Soundtrack Pro.
Using Markers to Align Audio Clips to Timecode
You can add a time marker at a specific timecode position in a video clip, and align audio
clips with the time marker or with a Final Cut Pro scoring marker.
Note: In order to add a marker at a specific timecode position, the Time ruler units must
be set to the timecode format of the video in your project.
To add a time marker at a specific timecode position in a video clip
Do one of the following:

Type the timecode position where you want to add the marker in the Time display, press
Return, then choose Mark > Insert Time Marker (or press M).

Make the Details tab active, add a time marker, select the marker handle, then enter a
new position in the Position value slider in the Details tab.

To align an audio clip with a marker
Make sure that snapping is turned on and that Markers is selected in the View > Snap to
menu, then drag the clip to the position of the marker in the Timeline.

With Markers selected,
you can align a clip
with a marker.

Note: You can temporarily turn snapping on or off by pressing N.
Scoring a Marker to the Playhead
For tracks set to Beats-based time format, you can score a time marker or Final Cut Pro
scoring marker to the playhead, so that you can synchronize the audio with the video.
Scoring a marker to the playhead adjusts the tempo so that the required number of beats
exactly fills the amount of time between the last tempo change and the marker’s position
in the Time ruler.

Chapter 6 Working in the Timeline

177

When you score a marker to the playhead, a set of special envelope points is created in
the project’s tempo envelope, from the previous envelope point (or the beginning of the
tempo envelope, if no previous envelope point exists) to the position of the marker. These
special envelope points are locked and cannot be moved (but can be deleted). The locked
envelope points, and the segment of the tempo envelope between them, appear red.
The tempo change created when you score a marker to the playhead is always
instantaneous; that is, the tempo changes from the previous tempo immediately, without
ramping. The distance between the two envelope points determines whether the resulting
tempo change can be heard easily. If the resulting change in tempo sounds too abrupt,
you can edit the tempo envelope to make the tempo change less noticeable.
To score a marker to the playhead
1 Select the marker’s handle at the top of the Timeline, above the Time ruler.
Click the marker
handle at the top
of the Timeline.

2 Choose Mark > Score Marker to Playhead.

The marker is scored
to the playhead.

Note: If you score a marker to the playhead, and the tempo change resulting from the
scoring operation sounds too noticeable or extreme, you can undo the scoring operation.
After undoing the scoring operation, add an envelope point to the tempo envelope at a
point after any audio clips you do not want to be affected by the tempo change, but
before the marker to be scored, then repeat the scoring operation.
You can also adjust the tempo relative to a marker’s position, so you can synchronize the
marker’s position with the Beats-based units.

178

To adjust the tempo relative to a marker’s position
Option-drag the marker in the Timeline.

Chapter 6 Working in the Timeline

As you drag, the red segment of the tempo envelope moves vertically as the tempo
changes.

Transposing Tagged Audio Clips
Soundtrack Pro includes a large selection of Apple Loops that you can use to add Foley
effects, background ambience, sound effects, and music transitions to your projects.
Apple Loops tagged as looping files automatically match the tempo and key of the project.
When you drag an audio file tagged with key information to the Timeline, Soundtrack Pro
transposes the clip to the project key. You can transpose tagged clips to another key to
create chord progressions from the same audio file or to achieve other musical effects.
You can transpose a tagged clip to any interval from one octave above (+12 semitones)
to one octave below (-12 semitones) its current key.
Note: Soundtrack Pro uses the key tag in the audio file to transpose it. In order to be
correctly transposed, the file must be tagged.
To transpose a tagged audio clip
Do one of the following:

Select the clip, choose Clip > Transpose, then choose the number of semitones by which
you want to transpose the clip up or down.

Select the clip, open the Details tab, then use the Transpose pop-up menu to choose the
number of semitones by which you want to transpose the clip up or down.

Replacing the Source Audio in a Clip
Each audio clip in the Timeline has a set of properties specific to the clip, including
duration, speed, and transposition. You can replace the source audio in the clip while
preserving the clip’s properties. This feature has a variety of uses, such as letting you try
out similar audio files (for example, music beds or sound effects) while maintaining the
clip’s duration, position in the Timeline, and transposition.
For information about properties of audio clips, see Reconnecting Media Files.
To replace the source audio file for a clip
1 In the Timeline, select the clip for which you want to replace the source audio.

Chapter 6 Working in the Timeline

2 In any media tab, Control-click the audio file that will replace the selected clip’s audio,
then choose Replace Selected Clips With [filename] from the shortcut menu.

...then choose the
Replace option from
the shortcut menu.

Select a clip, Control-click
the audio file that will
replace the original
audio...

When you replace the source audio in a clip, the clip’s duration and offset stay the same.
Only the portion of the new source audio file equal to the clip’s length plays. If the new
source audio file is a music loop and it is shorter than the clip’s length, the clip loops
when it reaches the end of the new source audio file. Notches appear on the clip to
indicate the point at which the clip starts looping.
You can replace the source audio in all clips using the same source audio file with another
source audio file by using the Select All Occurrences and Replace Selected Loops
commands together.
To replace the source audio file in all clips using the same source file
1 Select all occurrences of the clip for which you want to replace the source audio file,
following the steps described in Selecting Audio Clips in the Timeline.
Every clip using the same source audio file is selected.
2 In the Timeline, select the clip for which you want to replace the source audio.

Replacing Audio with Related Files
Once an audio clip is in the multitrack Timeline, Soundtrack Pro provides an easy way for
you to access other related audio files from a field recorder or other source. Files that
represent the same scene, shot, or take as recorded by multiple microphones are gathered
together based on a similar base filename or by the iXML Family UID. iXML metadata is
displayed in the Project tab, Details tab, and the Bin. For more information on viewing
iXML metadata, see Project Tab, Details Tab, and Viewing and Editing Projects in the Bin.
For more information about the iXML metadata specification, see the iXML website at
http://ixml.info. Soundtrack Pro looks for related recordings in the media folder, the
location of individual clips, and in the Bin.
You can easily select any related files in the multitrack Timeline on a per clip basis.

To replace a clip with a related file
In the Timeline, Control-click the audio file you want to replace, choose Replace with
Related File from the shortcut menu, then choose the audio file from the submenu that
will replace the selected clip’s audio.
If the file contains the iXML channel name, it is displayed next to the filename. The full
path to the file is shown as a tooltip if you hover over the filename.

Making Clip Channel Selections
A production sound recording often results in a stereo file or a multichannel file that
contains distinct data on different channels (for example, a lapel microphone on one
channel and a boom microphone on another channel). In such cases, you may want to
adjust a stereo clip so that it represents just one of its two channels in the Timeline. You
can also adjust a multichannel clip to represent just one of its channels, an adjacent pair
of its channels, or six channels. Soundtrack Pro provides two different ways to make these
channel selections in a clip.

Chapter 6 Working in the Timeline

181

Using the Shortcut Menu to Make a Channel Selection
Once a clip is in the Timeline, you can select (solo) an individual channel of a stereo file,
or you can select an individual channel or various pairs of channels of a multichannel file.
The clip retains this channel selection throughout the life of the multitrack project. If you
duplicate the clip, the copy also inherits the same channel selection. Changing any one
instance of a clip does not affect any other instance. For stereo files, there are two
options—channel 1 and channel 2. For six-channel files, there are nine different options.
If you select a number of clips that have been separated with the Blade tool, you are able
to make the same channel selections as if the clips were still attached. If you select multiple
clips, each with a different number of channels, and try to make a channel selection, you
can choose from any available mono options or choose All from the shortcut menu to
enable all of the channels in your selection.
Note: You can change the channel selection at any time by repeating the following steps.

To use the shortcut menu to make a mono channel selection from a stereo clip
Control-click the clip in the Timeline, then choose one of the following options from the
shortcut menu:
• Channel Select > Mono > 1
• Channel Select > Mono > 2

Choose a channel from
the shortcut menu.

The clip waveform display changes to a single (mono) waveform, and the clip functions
in the project as a mono file.

The clip’s waveform
display updates to a
single (mono) waveform.

182

Chapter 6 Working in the Timeline

To use the shortcut menu to make a channel selection from a multichannel clip
Control-click the clip in the Timeline, then choose one of the options from the shortcut
menu.
If you choose a mono option, the clip waveform display changes to a single (mono)
waveform, and the clip functions in the project as a mono file. If you pick a stereo option,
the clip waveform display changes to a stereo waveform, and the clip functions in the
project as a stereo file.

Separating Channels by Option-Dragging
You can separate the channels of stereo and multichannel clips into individual clips as
you drag them to the Timeline. When adding a clip to the Timeline from either the Browser,
Bin, or Finder, holding down the Option key while dragging will automatically generate
mono clips from a stereo or multichannel file. The dragged clip becomes a vertical stack
of clips, with the first under the pointer and the rest on subsequent tracks.
To convert the channels of a stereo or multichannel clip into individual clips as you
add it to the Timeline
1 Option-click the clip in any of the Soundtrack Pro media tabs.
2 Continue to press the Option key as you drag the clip to the Timeline.
Option-drag a stereo
file from the Browser
to the Timeline.

The stereo file is split
into two mono
files—each in its
own track.

Chapter 6 Working in the Timeline

183

The dragged clip becomes a vertical stack of clips, with the top clip under the pointer
and the rest on subsequent tracks. If you dragged a stereo clip, the stack consists of two
clips, one for each channel. If you dragged a six-channel clip, the stack consists of six clips,
one for each channel.

Combining Separate Clips to Create Multichannel Clips
In Soundtrack Pro, you can create a single multichannel clip by combining separate clips.
To create a single multichannel clip from separate clips
1 Select up to 24 separate source clips in any one of the Soundtrack Pro media tabs (Bin,
Browser, Search, or Favorites).
2 Drag the clips to a track in the Timeline.
The clips are combined into a single multichannel clip.
Drag multiple mono
source files into the
Timeline to create a
multichannel clip.

Note: This feature is available for mono source files only.

Editing Clip and Track Properties
In Soundtrack Pro, you can easily view and adjust the specific details about individual
clips and tracks.

Setting Clip and Track Colors
Soundtrack Pro allows you to set colors for clips and tracks. Setting a clip or track color
is a useful way to differentiate a set of clips from the rest of the clips or tracks in the
Timeline. For example, you could color-code your clips by category: dialogue, music, and
effects. This helps you organize your project visually. By default, video clips are set to blue
and audio clips are set to green, but you can change the color of audio clips and tracks
at any time.

You can change the
colors of audio clips
and tracks.

There are four ways to set the color of a clip or a selection of clips.
To set the color of a clip
Do one of the following:

Select the clip in the Timeline or the Bin, choose Clip > Color, then choose a color from
the submenu.

Editing Audio in the Multitrack
Timeline

You can edit the contents of clips with actions and operations in the Process menu, in
addition to the operations such as trimming and moving described in Working in the
Timeline. You can apply these actions and operations after first making a selection in the
Timeline or in the File Editor tab using the Selection tool or the Timeslice tool.
This chapter covers the following:
• How Selection Type Affects Actions (p. 189)
• Editing in Place (p. 191)
• How Clips Are Affected by Media File Editing (p. 192)
• How Source Audio File Editing Works in a Multitrack Project (p. 192)
• Making an Independent Copy of a Clip (p. 193)
• Using the Multitrack Timeline and the File Editor Together (p. 193)
• Editing with the Timeslice Tool (p. 196)
• Processing Audio Clips (p. 201)
• The Lift and Stamp Tools and the Sound Palette (p. 201)

How Selection Type Affects Actions
The region of media affected by actions and operations in the Timeline is determined by
the type of selection:
• When using the Selection tool, the operation affects the media from the In point to
the Out point of the selected clip in the Timeline.
• When using the Timeslice tool, the operation affects the selected regions of the media
of the clips in the Timeslice.
• When making a selection in the File Editor tab, the operation affects the selected region
of the media.

189

In Soundtrack Pro, actions and process menu operations are not applied directly to a clip,
but to an audio file project Soundtrack Pro creates that is shared by all clips referencing
the original source media. This means that you can apply common cleanup
operations—such as noise reduction—to a single source media file that is referenced by
multiple clips. If you need to apply actions to a single, specific instance of a clip, you must
make an independent copy of that clip. For more information, see Making an Independent
Copy of a Clip.

Multitrack Timeline before an edit is made

190

Chapter 7 Editing Audio in the Multitrack Timeline

Multitrack Timeline after an edit is made

If you prefer, you can also double-click a clip in your multitrack project and its media file
opens in the File Editor project view, ready for waveform editing. Changes you make to
the file are instantly reflected in the multitrack project.

Editing in Place
You can view and modify a clip’s media file in the File Editor tab without losing the context
of your multitrack Timeline. This is called editing in place. Simply select a clip in the Timeline
and it appears in the File Editor tab below. The playheads in the Timeline and the File
Editor tab are synchronized so you can play the media file within the context of your
whole multitrack project. Any changes you make to the media file are updated in the
Timeline immediately.
Editing a clip’s media file in place (directly in the Timeline) is nearly identical to editing
the same media file in the Soundtrack Pro File Editor. All of the same effects, editing tools,
and waveform views are available. However, there are a few differences:
• Timeline and File Editor playhead synchronization: When you edit a clip’s media file in
place, the Timeline and File Editor playhead are synchronized so you can work with
the media file within the context of your multitrack project.

Chapter 7 Editing Audio in the Multitrack Timeline

191

• Multiple region markers: Because a media file may be referred to by multiple clips in a
multitrack project, you may see multiple region markers above a media file in the File
Editor. Each region marker shows the In and Out points of a clip in the Timeline that
refers to this media file. This alerts you to the fact that changes you make to this media
file may affect multiple clips.

Multiple In and
Out points

How Clips Are Affected by Media File Editing
When you modify a media file in a multitrack project, all clips that refer to that media file
are updated simultaneously. For example, if you have ten clips referring to the same
media file and you double-click one of the clips to modify its underlying media file, any
changes you make to the media file affect all ten clips.

How Source Audio File Editing Works in a Multitrack Project
When you edit a clip in place or open a clip in the File Editor tab, the way the source
audio file is handled depends on its file format.
• If the clip’s audio file format is a native Soundtrack Pro audio file project: The audio file
project is opened directly in the File Editor tab, allowing you to make nondestructive
changes to the media.
• If the clip’s audio file format is a flat file such as an AIFF or WAVE file: Soundtrack Pro
automatically creates a Soundtrack Pro audio file project for the flat file and relinks all
clips in the project to the new audio file project. This allows you to work with this media
nondestructively. Each time you save your multitrack project, any newly created audio
file project media files are saved to the Edited Media Location on your hard disk. (You
can change this location by choosing Soundtrack Pro > Preferences and then clicking
General.)

192

Chapter 7 Editing Audio in the Multitrack Timeline

Making an Independent Copy of a Clip
Any time you use multiple instances of the same clip in a multitrack project, the clip refers
to the same source media file. This means that any time you modify the media file, all of
the clips that refer to the media file are affected. How do you edit just one clip without
editing its source media? In cases where you only want to make changes to a single clip,
you can make a new copy of the clip’s media file in a new audio file project and link this
clip to the new audio file project.
To create a copy of a clip’s media file and link the clip to the new audio file project
1 Select the clip whose source media file you want to copy.
2 Control-click the clip in the Timeline, then choose Replace with Independent Audio File
Project from the shortcut menu.

A new Soundtrack Pro audio file project is created that includes a copy of the original
audio file. Only media between the clip’s In and Out points is copied, plus handles on
either side for later trimming, if necessary.
The new audio file project opens in the File Editor tab and the clip now links to the new
audio file project.
Note: The default handle duration is 5 seconds. To adjust the handle duration, go to
Soundtrack Pro > Preferences > General.

Using the Multitrack Timeline and the File Editor Together
One of the unique advantages of Soundtrack Pro is the combination of nondestructive
waveform editing in the context of a multitrack Timeline. This section focuses on how
you can exploit this powerful toolset in your sound editing project.

Chapter 7 Editing Audio in the Multitrack Timeline

193

Making Changes in the File Editor and Hearing Them in the Timeline
When you arrange a multitrack project, you frequently need to edit and adjust individual
audio files, and immediately hear the results in the context of the larger multitrack
Timeline. You can do this by using the Timeline and File Editor in tandem.
To make changes in the File Editor and hear the results in the Timeline
1 With the File Editor tab active, select a clip in the Timeline that you would like to adjust.
The waveform for the clip appears in the File Editor.

2 Make adjustments and edits to the clip in the File Editor.

194

Chapter 7 Editing Audio in the Multitrack Timeline

For information on making basic edits, see Working in the File Editor. For information on
processing effects, see Processing Audio Files. For information on analyzing files, see
Overview of Analyzing and Fixing Problems in an Audio File.

3 As you make changes to the clip in the File Editor, the Actions tab records the changes.
You can adjust, edit, and reorder the actions as needed.

For information on using actions, see Working with Actions.
Note: Any time you apply a command from either the Edit menu or the Process menu,
Soundtrack Pro creates an audio file project (.stap) for the source audio file if one doesn’t
exist already. Clips that reference the audio source file all have their audio source replaced
with that audio file project.
4 Play the clip.
Soundtrack Pro plays the clip together with any other active tracks in the Timeline.
5 Make any other adjustments and edits to the clip in the File Editor (or to the actions in
the Actions tab) and play the clip again. Repeat as necessary.

Using the File Editor to Add Part of a File to the Timeline
A common task for sound editors is adding sound effects or ambient clips to a multitrack
project. Often you will use one or more small sections from a longer source file. In addition
to the normal cut or copy and paste operations used to add part of a file to the Timeline,
you can use the File Editor tab in conjunction with the Timeline.
To add small sections of a longer audio file to a multitrack project
1 Open a multitrack project in the Timeline.
2 Select a file in the Browser, Search tab, or Favorites tab.
3 Drag the selected audio file to the File Editor tab.

Chapter 7 Editing Audio in the Multitrack Timeline

195

4 Select a portion of the audio file in the File Editor tab.
5 Drag the selection to a track in the Timeline.
There are multiple techniques you can use to spot audio. For more information, see
Spotting Clips to the Timeline.
Optionally, you can open the Multipoint Video HUD to give you visual context for spotting
the sound effects to the Timeline. For more information about the Multipoint Video HUD,
see Scrubbing and Spotting with the Multipoint Video HUD.

Editing with the Timeslice Tool
You can use the Timeslice Tool to make time-based selections. Unlike selections of multiple
clips with the default Selection tool (which can only select whole clips), Timeslice tool
selections are entirely time-based. This means you can use the Timeslice tool to select
portions of clips or portions of multiple clips. You can also easily move and adjust the
size of a Timeslice tool selection and add or remove entire tracks from the selection. This
is most important for processing effects.

Note: The currently active channel selections are the only channels affected by the
Timeslice tool.
Use the Timeslice tool to select any combination of the following:
• One or more clips or tracks and their envelopes
• Portions of one or more clips or tracks and their envelopes
To make a selection with the Timeslice tool
1 Click the Timeslice tool at the top of the Timeline (or press W).
2 Drag across any portion of the Timeline to make a Timeslice selection.
A Timeslice selection rectangle appears over the area.

196

Chapter 7 Editing Audio in the Multitrack Timeline

To select a portion of a clip with the Timeslice tool
1 Click the Timeslice tool at the top of the Timeline (or press W).
2 Drag across any portion of the clip with the Timeslice tool.

To move a Timeslice selection
Click the center of the Timeslice selection, then drag it to a new location in the Timeline.

To add a noncontiguous track to a Timeslice selection
Command-click anywhere in the track.
Note: You can add tracks that are not adjacent to or contiguous with the selection.

To remove a track from a Timeslice selection
Command-click anywhere in the track.
You can select a master Timeslice that includes the audio content and the envelopes of
all tracks, busses, and submixes, including the video’s audio track. (Only a master Timeslice
contains busses and submixes.)

To make a master Timeslice selection
1 If the Timeline is in Select Only Clips mode, enable Select Envelope Points With Clips
mode (or press Option–E).
2 Using the Timeslice tool, drag in the selection bar of the video track, located above the
Time ruler.
Drag in the selection bar
of the video track to
create a master Timeslice.

Cutting, Copying, and Pasting Timeslices
You can cut or copy a Timeslice and paste it at a different position in the Timeline.

198

Chapter 7 Editing Audio in the Multitrack Timeline

Make sure the Timeline is in Select Envelope Points With Clips mode if you want envelopes
to be cut or copied along with a Timeslice. Timeslice copies do not create extra envelope
points around the perimeter of your selection. To ensure predictable results when pasting
Timeslices, it is a good idea to create extra envelope points at the boundaries of your
Timeslice selection.

To cut a Timeslice
Select the Timeslice, then choose Edit > Cut (or press Command-X).
If you want envelopes to be cut along with your Timeslice, enable Select Envelope Points
With Clips mode (or press Option–E if the Timeline is in Select Only Clips mode).

To copy a Timeslice
Select the Timeslice, then choose Edit > Copy (or press Command-C).
If you want envelopes to be copied along with your Timeslice, enable Select Envelope
Points With Clips mode (or press Option–E if the Timeline is in Select Only Clips mode).

To paste a Timeslice
Set the playhead at the position where you want to paste the Timeslice, then choose Edit
> Paste (or press Command-V).
The topmost track of the Timeslice is pasted in the currently selected track, and any
remaining tracks are pasted in the tracks below the selected track. If there is no track
selected, the Timeslice is pasted on the first track of the project. If not enough tracks exist
for the number of tracks in the Timeslice, a dialog appears asking if you want to create
additional tracks.

To paste insert a Timeslice
Set the playhead at the position where you want to paste insert the Timeslice, then choose
Edit > Paste Special > Paste Insert.
If the Timeslice is from a single track, it is inserted in the first selected track at the current
playhead position. If the Timeslice is from multiple tracks, the Timeslice is inserted in the
first selected track, and any remaining tracks are pasted in the tracks below the selected
track. In both cases, audio at the position of the playhead is rippled along the Timeline
the length of the pasted audio. If not enough tracks exist for the number of tracks in the
Timeslice, a dialog appears asking if you want to create additional tracks.
Note: The Paste Insert command works only with Timeslices.
Any tracks that you want to be rippled must be included in the original Timeslice selection.
Important: Because the Paste Insert command shifts audio, care must be taken to ensure
your project remains in sync.

Deleting the Contents of Timeslices
You can delete the contents of a Timeslice if you want.

Chapter 7 Editing Audio in the Multitrack Timeline

199

To delete the contents of a Timeslice selection
Select the Timeslice, then choose Edit > Delete (or press the Delete key).

Changing the Timeslice Selection Area
You can change the height or the length of a Timeslice selection area to include more of
the Timeline, either graphically or numerically.

To extend the Timeslice selection area graphically
Shift-click any track at the point to which you want to extend it.

Shift-click the Timeline to
extend a Timeslice.

To change the In point, Out point, or duration of a Timeslice numerically
1 Make a Timeslice selection in the Timeline.
The Details tab displays Timeslice controls.
2 In the Details tab, type a new value in the In value slider, the Out value slider, or the
Duration value slider.

3 Press Tab or Enter to confirm the new value.
Note: To the right of the Timeline transport controls is the Selection Length value slider.
When a Timeslice is active, the Selection Length value slider shows the length (duration)
of the active Timeslice. You can use this value slider the same way you use the Duration
value slider in the Timeslice section of the Details tab.
For more information on how to use value sliders, see About Changing Values and
Timecode Entries.

Processing Audio Clips
You can process audio files in the Multitrack Timeline in a variety of ways. You can choose
processing effects and other operations from the Process menu and apply them to part
or all of the clips visible in the Multitrack Timeline. When you choose an item from the
Process menu, the item appears as an action in the Actions list. Each of the processing
effects available in the File Editor is also available in the Multitrack Timeline. For more
information on processing effects and other operations from the Process menu, see
Processing Audio Files.

The Lift and Stamp Tools and the Sound Palette
The Lift and Stamp tools provide a time-saving way to apply work you have done on one
clip to one or more other clips. Use the Lift tool to copy properties from selected clips
and create a processing template in the Sound Palette that can be applied to other clips.
Use the Stamp tool to apply those properties to the other clips.

Using the Lift and Stamp Tools
When you first lift properties with the Lift tool, Soundtrack Pro creates a temporary
template in the Sound Palette named Lifted Data (Track Name), with Track Name being
the track holding the source clip.

Chapter 7 Editing Audio in the Multitrack Timeline

201

To lift properties from a clip in the Timeline
1 Click the Lift tool at the top of the Timeline (or press UU).
The Sound Palette appears. As you move the pointer over clips in the Timeline, it changes
into the Lift pointer.
2 If you want to limit the type of properties lifted, deselect any of the three checkboxes at
the top of the Sound Palette:
• Lift Equalization Print: When this checkbox is turned on, the Lift command copies the
average frequency spectrum of the selected clip.
• Lift Voice Level: When this checkbox is turned on, the Lift command copies the average
amplitude of the selected clip. The algorithm used when this option is turned on is
designed to focus on vocal qualities only; non-dialogue artifacts like loud crashes or
coughs are ignored when calculating the average amplitude.
• Lift Process Items: These include processing effects in these categories: Dynamics,
Distortion, EQ and Filter, Modulation, Reverb/Delay, Miscellaneous, and Mac OS.
3 Click a clip in the Timeline whose properties you want to lift.
Soundtrack Pro creates a temporary template named Lifted Data (Track Name) with Track
Name being the track holding the source clip. The clip properties appear in the list on
the right of the Sound Palette HUD. The pointer immediately changes to the Stamp
pointer, ready for you to stamp the template of lifted properties to another clip. The
properties in the Sound Palette template appear in the same order they appear in the
Actions tab for the source clip.
To stamp properties on one or more clips in the Timeline
1 If you are stamping on more than one clip, select the target clips in the Timeline.
2 In the Sound Palette, select the template or preset containing the properties you want
to stamp. (This is only necessary if there are already presets on the left side of the Sound
Palette.)

202

Chapter 7 Editing Audio in the Multitrack Timeline

3 Choose one of the following from the pop-up menu in the center-bottom portion of the
Sound Palette:
• Add: Adds the properties selected in the Sound Palette to the list of actions in the
target clip’s Actions tab.
• Replace: Replaces the actions in the target clip’s Actions tab with the properties selected
in the Sound Palette.

Choose Add or Replace
from the pop-up menu.

4 Do one of the following:
• Click the Stamp tool at the top of the Timeline (or press U), then click the target clip or
clips in the Timeline.
• If the target clip is already selected in the Timeline, click Stamp in the lower-right corner
of the Sound Palette.
Actions appear in the target clip’s Actions tab for each property listed in the selected
template or preset in the Sound Palette. They appear in the same order as they appear
in the Sound Palette.
Note: By default, Soundtrack Pro applies equalization every time you use the Lift and
Stamp feature. This equalization automates the Match EQ effect, which matches the
average frequency spectrum of the target clip to that of the source clip.

Working with Sound Palette Presets
You can use the Sound Palette to customize the processing template by enabling and
disabling various properties, naming the template, and saving it as a preset. You can also
add a thumbnail image to represent the preset. Presets are saved in the Sound Palette
so that you can select and edit them and apply them in multiple multitrack projects.

About the File Editor
The Soundtrack Pro File Editor gives you extensive audio file editing capabilities. You can
edit audio files in many different ways in the File Editor tab and File Editor project view.
You can edit the entire file or select part of the file to edit. You can cut, copy, and paste
audio, and graphically edit audio files using a variety of tools in the File Editor.

207

You can open and edit an audio file with up to 24 channels in the File Editor, view it in
Waveform or Frequency Spectrum view, process the file using actions, analyze it for
common audio problems, fix analyzed problems individually or together, and then save
the edited file as an audio file project or as a standard audio file. And you can do all this
while working interactively with same audio file in the multitrack Timeline and while
hearing (and seeing) the file in the context of other audio files in a multitrack project.

If there is an existing selection, the selection is extended to the end of the audio file (for
Forward) or to the beginning of the audio file (for Backward).
If there is not an existing selection, Soundtrack Pro creates a new selection across active
channels from the end of the audio file (for Forward) or from the beginning of the audio
file (for Backward).
Note: If you hold down the Option key, the menu items will read Select > All Forward
and Select > All Backward, and behave the same as described earlier except the selection
will be across all channels instead of just the selected channels.

Adjusting Selections to a Zero Crossing
A zero crossing is a point in an audio file where the amplitude is zero. When you edit an
audio file in the File Editor, if the beginning or end points of your edit do not occur at a
zero crossing, the edited audio file can have unwanted noise at the beginning or end of
the edited area or both. Subsequent editing of the file, such as normalizing or increasing
the gain, can increase this unwanted noise.
Once you have made a selection in the File Editor, you can fine-tune the selection so that
it begins or ends at the nearest zero-crossing point.

Chapter 8 Working in the File Editor

215

To adjust a selection to the zero crossing
1 Make a selection in the File Editor.
2 Choose Edit > Adjust Selection to Zero Crossing and choose one of the following from
the submenu:

Use the Audio Stretching
tool to shorten or
lengthen the selected
area of the waveform.

Note: You can edit a graphically performed time stretch by double-clicking the action in
the Actions tab. For more information about audio stretching, see Time Stretch.
When you shorten a selection of an audio file using the Audio Stretching tool in the File
Editor, the empty part of the selection area is filled with ambient noise if an ambient
noise print exists. If no ambient noise print exists, the empty part of the selection area is
filled with silence. Shortening a selection using the Audio Stretching tool does not change
the length of the audio file.
When you lengthen the selection using the Audio Stretching tool, any audio overlapped
by the lengthened selection area is deleted. Lengthening the selection past the end of
the file changes the length of the audio file.
If you hold down the Option key while dragging the selection with the Audio Stretching
tool, the audio following the selection area ripples forward when you lengthen the
selection and ripples backward when you shorten the selection. In both cases, using the
Option key changes the length of the audio file.
Note: Stretching an audio file by a large amount can degrade the sound quality of the
audio file.
For information about stretching an audio file numerically using the Process menu, see

Using Frequency Spectrum View
When you first open the File Editor, it shows the audio file in Waveform view. You can
also view and edit an audio file in Frequency Spectrum view. Frequency Spectrum view
gives you a way to find areas of significant frequency change that aren’t visible in a
waveform.

Viewing an Audio File in Frequency Spectrum View
In Frequency Spectrum view, the display shows the frequency spectrum of each channel
of a stereo audio file on a scale from 0 Hertz (Hz) to half the sample rate of the file. For
example, for a 48 kHz audio file, the scale progresses from 0 Hz to 24 kHz.

high frequency content.
• Minimum Frequency slider and value field: Allows you to view a subset of the frequency
range (for example, only the frequencies over 1 kHz).
• Maximum Frequency slider and value field: Allows you to view a subset of the frequency
range (for example, only the frequencies under 9 kHz).
• Minimum Power slider and value field: Defines the bottom of the scale (where the blue
portion of the gradient starts).
• Maximum Power slider and value field: Defines the top of the scale (where the red portion
of the gradient ends).

Chapter 8 Working in the File Editor

227

• Analysis Window pop-up menu: To display the audio file in Frequency Spectrum view,
part of the audio data for each given point in time is analyzed. Each method of analysis
represents a slightly different compromise between frequency resolution and spectral
leakage. You can choose between several different analysis methods, called analysis
windows, used to display the frequency spectrum in Frequency Spectrum view.
• Window Size pop-up menu: The number of samples used for Frequency Spectrum view.
This parameter trades off frequency resolution for time resolution. Smaller window
sizes are more accurate timewise, but smear frequency information across adjacent
frequencies (vertical lines, or transients, appear sharper). Larger window sizes provide
a more accurate frequency display, but will smear things horizontally (horizontal lines
appear sharper, but transients are smeared).
• Frequency Scale buttons: Use Frequency Scale to switch between linear display (in which
harmonics appear evenly spaced) and logarithmic display (in which octaves appear
evenly spaced).
• Color pop-up menu and gradient slider: Use the menu and slider to customize the gradient
for Frequency Spectrum view.

Guidelines for Using the Frequency Selection Tool
Here are some further guidelines for editing in Frequency Spectrum view with the
Frequency Selection tool:
• All paste edits, including paste, paste mix, and paste repeat, are supported for frequency
selections.
• Pasting to an ordinary (full frequency range) selection follows the same conventions
as in the Waveform view.
• Pasting to a narrow frequency range causes the contents of the Clipboard to be filtered
before being pasted. This filtered result is added to the result of applying the
complementary filter to the original audio with any necessary truncation or zero-padding
if the length of the selection is greater than or less than, respectively, the length of the
Clipboard audio data.
• When you switch between Frequency Spectrum view and Waveform view, ordinary
(full frequency range) selections are preserved, but any narrow frequency range
selections are reset.

Chapter 8 Working in the File Editor

Working with Actions
Actions give you an extremely flexible and powerful way to edit audio files in the File
Editor. You can apply an action to an entire file or a selected part of the file, including
applying an action to only one channel of a stereo audio file. You can turn individual
actions on or off and reorder actions in the Actions list, changing the sequence in which
the actions change the audio file. You can adjust action settings after applying the action,
and can flatten actions.

Applying Actions
You start working with actions by applying an action to the audio file or the currently
selected part of the file.
To apply an action
1 With the file open in the File Editor, choose an item from the Process menu.
The item appears in the Actions list.
Actions tab

Actions

Resulting waveform

Action Insert bar

2 Some actions have a dialog that appears when you choose the item from the Process
menu. Adjust the settings in the dialog, then click Apply.
The action is added to the Actions list, and the waveform display updates to show the
change to the audio file. You can hear the change when you play the project. Some
actions may take a moment to apply. In this case, a progress bar appears, indicating that
the action is being applied.
Some effects, including reverb and delay, add audio that extends past the end of the file.
This is called an effect tail. When you apply a processing effect that produces an effect
tail to an audio file in the File Editor, the file is lengthened to include the tail until the
point at which the tail falls below -96 dB. If you apply a processing effect that produces
a tail to a selection, the tail is mixed with the audio following the selection. If the tail
extends past the end of the file, the file is lengthened to include the effect tail until the
point at which the tail falls below -96 dB.
When you apply an action that adds a short (0.1 second or less) tail to an Apple Loops
audio loop, the tail is shortened to preserve the overall length of the loop.

Chapter 8 Working in the File Editor

231

Editing Actions
Many actions have settings that you can edit. When you apply an action that has editable
settings, a dialog appears, letting you edit the action’s settings. You can edit an action’s
settings any time you are working in the File Editor.
To show an action’s settings
Do one of the following:

In the Actions list, Control-click the action you want to edit, then choose “Edit Settings
For [action name]” from the shortcut menu.

µ
µ

Double-click the action in the Actions list.
In the Actions list, select the action you want to edit, then choose “Edit Settings For [action
name]” from the Actions pop-up menu.
If the action has no editable settings, the Edit Settings menu item appears dimmed.

Adjusting and Applying Action Selections
You can adjust the selection for an action or set the current selection in the File Editor to
an action’s selection.
To adjust an action’s selection
Do one of the following:

Make a selection in the File Editor, then in the Actions list, Control-click the action, then
choose “Set Selection For [action name]” from the shortcut menu.

Make a selection in the File Editor, then in the Actions list, choose “Set Selection For
[action name]” from the Actions pop-up menu.
The action is shifted to the selected region.
To set the File Editor’s current selection to the action’s selection
Do one of the following:

In the Actions list, Control-click the action, then choose “Selection For [action name]” from
the shortcut menu.

In the Actions list, choose “Selection For [action name]” from the Actions pop-up menu.
The action’s selection becomes the current selection in the File Editor.

Turning Actions On and Off
You can turn individual actions on and off in the Actions list and hear the result when
you play the audio file. The waveform display updates to show the change to the audio
file. Depending on the length of the file, turning actions on and off can take time.

232

To turn an action off
In the Actions list, deselect the checkbox next to the action name.

Chapter 8 Working in the File Editor

To turn an action on
In the Actions list, select the checkbox next to the action name.

Reordering Actions
You can reorder actions after applying them to an audio file. The order in which effects
and other actions occur can drastically change the resulting sound of the audio file.
Depending on the length of the file, reordering actions can take time.

To reorder actions
In the Actions list, drag the actions you want to reorder up or down to new positions.
You hear the change when you play the audio file. The waveform display updates to
show the change to the audio file.

Using the Action Insert Bar
The Action Insert bar appears as a purple marker along the left side of the Actions list
with an associated bar that extends across the list. As you apply actions, the Action Insert
bar moves below the last action applied.

Action Insert bar

You can move the Action Insert bar up or down to a new position in the Actions list. Only
actions before the Action Insert bar are heard when you play the project, so you can
control which actions are heard by moving the bar. The purple strip to the left of the
checkboxes in the Actions list indicates the actions that are heard when you play the
project.
When you choose an item from the Process menu, it is applied directly following the
Action Insert bar. By moving the bar, you set where in the list the next action is applied.

Chapter 8 Working in the File Editor

233

To set the position of the next applied action
Drag the Action Insert bar up or down in the Actions list to the position you want.

Drag the Action Insert
bar to the position
you want.

Reversing the Order of the Actions List
You can reverse the order in which actions are shown in the Actions list, so the last action
applied appears at the top of the list. This is useful when your project has a large number
of actions.

To reverse the order of the Actions list
Click the triangle at the upper-right corner of the Actions list. Click the triangle again to
return the list to its default order.
Click the triangle to
reverse the order of
the Actions list.

When you reverse the order of the Actions list, the Action Insert bar appears at the top
of the list instead of at the bottom. You hear actions below the Action Insert bar in the
list, rather than above it. When you choose an item from the Process menu, it is applied
directly above the position of the Action Insert bar.
Reversing the order of the Actions list affects only the visual appearance of the list. The
order in which actions are applied to the audio file is unchanged.

Flattening Actions
You can flatten the actions in a project to a single action. Flattening actions renders the
actions into the file, reducing the complexity of the file and the file size. When you flatten
actions, all existing actions are removed from the Actions list, and you can no longer
reorder the actions or edit their action settings, unless you undo flattening the actions.
Some items in the Process menu, including Convert to Mono and Resample, flatten all
actions in the project.

2 Click Play or press the Space bar.
When you deselect an action, its settings are saved and are available when you select
the action again.

Comparing the Last Two Actions
You can quickly compare the last two actions applied to an audio file or selection. This
is helpful when you want to try out two similar actions, and hear which one you like
better.
To compare the last two actions
1 Do one of the following:
• Choose Process > A/B Last Two Actions.
• Choose A/B from the Actions pop-up menu (or press Command-F1).
2 Click Play or press the Space bar.

Chapter 8 Working in the File Editor

235

You hear the first of the two actions. The checkbox of the second action appears deselected
in the Actions list.
3 Do one of the following:
• Choose Process > A/B Last Two Actions again.
• Choose A/B from the Actions pop-up menu (or press Command-F1) again.
You hear the second of the two actions. The checkbox of the first action appears deselected
in the Actions list.

Deleting Actions
You can delete an action if you decide you no longer want it in the project.

To delete an action
Select the action in the Actions list, then press Delete.

Limitations of Actions That Change the File’s Length
Some actions change the overall length of the audio file by inserting or deleting audio.
These include inserting silence, noise, or a waveform, time stretching, and deleting part
of a file. Recording audio, pasting, and adding an effect with a “tail” can also change the
file’s length. In the Actions list, the selection checkbox for each action that changes the
file’s length appears red, making it easy to visually distinguish those actions.
Each selection you make in the File Editor applies to a specific range of time, and each
action applies to a range of time defined by the selection at the time the action is applied.
Because selections and actions apply to a range of time, changing the file’s length can
change the audio to which a selection or action applies. In the File Editor, you see the
selection remain in the same place (the same range of time as shown in the Time ruler)
and see the waveform under the selection change.
When you apply an action that changes the file’s length, any existing selections apply to
the same range of time, but the audio occupying that range of time may be different
than when you applied the action. For example, if you select a range of time beginning
five seconds after the start of an audio file, then insert one second of silence at the
beginning of the file, the selection still begins five seconds after the start of the file, but
the audio at the beginning of the selection corresponds to what was previously four
seconds after the start of the file.

236

Chapter 8 Working in the File Editor

If a project includes an action that increases the file’s length, and you turn off or reorder
that action, any selection that includes audio added by the length–changing action may
extend past the end of the shortened file. In this case, the selection applies to the
remaining audio in the selected range of time, but has no effect past the end of the file.
For example, if you have a five-second project that includes a one-second Insert Silence
action at the beginning of the project, and you select the last half-second of the project,
then turn off the Insert Silence action, the selection applies to the last half-second of the
project. However, the remaining half-second of the selection is empty.

Overview of Analyzing and Fixing Problems in an Audio File
Soundtrack Pro includes a set of audio analysis tools. You can analyze an audio file for
common problems and fix them individually or in a single operation.
There are different types of analysis you can perform:
• Clicks and Pops: Sudden, short peaks in the audio file can result from a variety of causes,
including mechanical defects in analog recordings. You can set the threshold above
which Soundtrack Pro considers peaks to be clicks or pops.
• (Power Line) Hum: Power lines and other electrical equipment can produce a steady
hum, often at 50 or 60 Hz. The hum can also include low-order harmonics of the
fundamental frequency.
• DC Offset: DC offset is a shift in the audio, causing the positive and negative parts of
the signal not to average to zero. DC offset can limit the dynamic range of an audio
file.
• Phase Issues: Phase issues can result from a distorted or inaccurate stereo image, caused
by poor microphone placement or other issues. When converting a stereo file to mono,
the presence of phase issues can cause the left and right channels to cancel each other
out partially or completely.
• Clipped Signal: A clipped or overloaded signal can result from several causes, including
poor gain staging in a preamp during recording, bad electrical cables, or surface damage
to an analog recording. If analysis identifies a clipped signal, Soundtrack Pro gives you
the option to soften the abrasive nature of the truncation.
• Silence: Silence detects the parts of the audio file at which the audio signal falls to zero
(0). You can set the threshold below which Soundtrack Pro considers the signal to be
silence.
The Power Line Hum, DC Offset, and Phase analysis types determine whether the audio
file or selection exhibits these problems. Because hum, DC offset, and phase issues tend
to last for long times, up to the entire length of the file, better results might be achieved
when analyzing the entire audio file or the part of the file you think has the problem.

Chapter 8 Working in the File Editor

237

On the other hand, the Clicks and Pops, Clipped Signal, and Silence analysis types tend
to be momentary and isolated rather than constant. If part of an audio file or selection
contains a large number of clicks and pops, for example, the analyzed waveform might
display the entire region as being problematic, rather than each individual click or pop.
However, when you fix these problems using the Fix button, Soundtrack Pro correctly
fixes each individual click or pop.

Analyzing and Fixing Problems in an Audio File
There are three steps in fixing problems in an audio file.
• Stage 1: Analyzing an Audio File
• Stage 2: Viewing and Interpreting the Analysis Results
• Stage 3: Fixing Analyzed Problems

Stage 1: Analyzing an Audio File
When you analyze an audio file, you can select which types of analysis to perform.
To analyze an audio file
1 In the File Editor, select the audio clip you want to analyze.
Note: When analyzing an audio file in the File Editor, some analysis types might produce
better results if you select a part of the audio file instead of the entire audio file. For more
information, see Selecting All or Parts of an Audio File.
2 Click the Analyze tab.

238

Chapter 8 Working in the File Editor

3 In the Analysis Type list that appears, select the checkboxes next to the types of analysis
you want to perform on the audio file.

Analysis Type list

Analysis tab

4 Click the disclosure triangle for the analysis types for which you want to set parameters
(there is a disclosure triangle next to these).
The Clicks and Pops and Silence analysis types have parameters you can set. Each type
has a Threshold slider you can drag to set the threshold for detecting clicks and pops or
detecting silence.
5 In the Parameter list on the right, do one of the following:
• Drag the Threshold slider left to lower the threshold or right to raise the threshold.
• Type a value in the Threshold field.
The Clicks and Pops Threshold slider uses an algorithm to detect transients that are clicks
or pops. Moving the slider to the right results in fewer clicks or pops being detected.
The Silence Threshold slider ranges from 0% to 10% of the full-scale level of the audio
file, which corresponds to a range of -infinity dB to -20 dB.

Parameter list

Analyze button

6 When you’re ready to analyze the file, click the Analyze button, located below the
Parameter list.

Chapter 8 Working in the File Editor

239

Stage 2: Viewing and Interpreting the Analysis Results
When you analyze an audio file, the problems detected through analysis are shown in
the Results list in the bottom section of the Analyze tab.

Results list

For each item, the following information appears in columns:
• Status: Shows whether the problem is fixed or not fixed.
• Problem: Shows the analysis type to which the problem belongs.
• Start: Shows the point at which the problem begins.
• Length: Shows the duration of the problem.
• Ch: Shows whether the problem occurs in the left channel (L), the right channel (R), or
both channels (LR) of a stereo audio file. If you analyze all or part of a monaural file, a
dash (-) appears in the column.

To view analysis results
In the Results list, select one or more items.
The part of the audio file to which the problem applies becomes red in the waveform
display, making it easy to see where in the audio file the problem occurs. If you select
multiple items, the parts of the audio file to which any of the selected problems apply
become red.
By default, the region shown in red in the waveform display includes some extra time
before the first sample with the problem and some extra time after the last sample with
the problem. This extra time is included so that when you play or loop the problem area,
you can hear the problem in context.

240

Chapter 8 Working in the File Editor

If you want, you can narrow the problem area to include only the samples identified as
having the problem, with no extra time.

To narrow the problem area to include only problem samples
Option-click the item in the Results list.
You can zoom in on an item in the Results list so you can see the problem area of the
audio file closely.

To zoom in on an item in the Results list

You can close the project when you no longer want to work on it, or close the
Soundtrack Pro window and close all open projects (both multitrack and audio file
projects).

To close a project
Choose File > Close Tab (or press Command-W).

To close all open projects and close the Soundtrack Pro window
Click the close button in the upper-left corner of the window.

Applying Realtime Effects in the File Editor Project View
Using the File Editor project view, you can apply realtime effects to an individual audio
file project and automate those effects. You can also render realtime effects to actions.
To add a realtime effect to an audio file project in the File Editor project view
1 Open an audio file or audio file project in the File Editor project view.
2 In the Effects tab, select a category in the Category list to display the effects for that
category in the Effect list.
3 In the Effect list, do one of the following:
• Double-click the effect you want to add to the track.
• Select the effect name, then click the Add Effect button.
• Drag the effect to the Effect Parameters area.
The effect’s advanced settings window appears, and the effect name appears in the Effect
Parameters area with its checkbox selected.
For more information on applying realtime effects, see Working with Realtime Effects.

Automating Realtime Effects in the File Editor Project View
Once you have applied realtime effects to an individual audio file project, you can
automate those effects in the File Editor project view.
To automate a realtime effect parameter
1 In the Effects tab, select the Auto checkbox next to the parameter’s control.
2 In the File Editor project view, click the Master Envelope button (in the lower-left corner
of the project pane) to show the envelopes for the audio file project.

244

Chapter 8 Working in the File Editor

3 Add and adjust envelope points in the effect’s envelope.

For information on adding and adjusting envelope points, see Working with Automation.

Rendering Realtime Effects to Actions
Choosing this command renders any realtime effects applied to the audio file project and
the project’s envelopes to an action in the Actions list, letting you turn these effects and
envelopes on or off, reorder them in the list, and save them with the audio file project.

To render realtime effects and envelopes to an action
Choose Process > Render to Action.
Once you render realtime effects and envelopes to an action, the realtime effects are
deleted from the project, and the envelopes are reset to their default values.
Some effects, including reverb and delay, add audio that extends past the end of the file.
This is called an effect tail. When you render realtime effects to an action, if any of the
effects creates an effect tail that extends past the end of the audio file, the file lengthens
to include the effect tail.

How Files Are Saved in the File Editor Project View
When you edit an audio file in the File Editor project view, the source audio file is handled
as follows:
• If the clip’s audio file format is a native Soundtrack Pro audio file project: Any changes you
make are saved to the audio file project, allowing you to make nondestructive changes
to the media.

Chapter 8 Working in the File Editor

245

• If the clip refers to a standard-format audio file (such as AIFF or WAVE): Soundtrack Pro
automatically creates a Soundtrack Pro audio file project for the flat file. When you
attempt to save the changes to the audio file project, the default File Type is Audio File
Project, which retains the nondestructive changes in the form of an Actions list. If you
change the File Type in the Save dialog to a flat file format (such as AIFF or WAVE), you
lose the nondestructive characteristics of a Soundtrack Pro audio file project.

Saving Audio File Projects from the File Editor Project View
You can save a project as an audio file project or as a standard audio file and can choose
other options when you first save the file. Audio file projects are saved with the extension
.stap. Saving a project as an audio file project lets you make changes to actions and other
edits when you reopen the project in the File Editor.
To save a project as an audio file project
1 Choose File > Save.
2 In the Save dialog, type a name for the file and browse to the location where you want
to save it.
3 Choose the file type for the project from the File Type pop-up menu.
The available choices in the Save dialog change depending on whether you choose Audio
File Project or an audio file format as the file type.
4 Click Save.

Saving Audio File Projects Containing Video
For audio file projects containing video, the video file is saved as a reference movie. If
the video file is moved or deleted, or if you copy the project to another computer, the
video may be missing when you open the project. To add the video to the project again,
drag the video file into the Video tab or the video track of the Timeline.

246

Chapter 8 Working in the File Editor

When you open a QuickTime movie in the File Editor as an audio file project, or send an
audio clip from Final Cut Pro to an audio file project, by default the source audio is
referenced. When you save the project by choosing File > Save As, you can include the
source audio in the project. If the source audio is moved or deleted, or if you copy the
project to another computer, the audio might not play correctly.
The first time you save an audio file project with referenced audio, a dialog appears asking
if you want to include or reference the source audio. Your choice becomes the default
behavior for new audio file projects and can be changed in the General preferences pane.
About Saving QuickTime Movies and File Size
When you lengthen or shorten the duration of a QuickTime movie in the File Editor by
adding or deleting audio, the file size of the movie might be larger than expected when
you save the movie. For example, if you shorten the duration of the movie by deleting
audio, the file size of the movie does not decrease.
When you change the sample rate, bit depth, or number of channels in a QuickTime
movie, the file size of the saved movie might be larger than expected. Also, when saving
to a QuickTime movie that uses a compressed audio format, the audio is saved
uncompressed and the file size might be larger than expected.
In all of the above cases, saving the movie to a different location results in the file being
saved at the correct file size.

Saving Audio Files from the File Editor Project View
You can also save a project as a standard audio file from the File Editor project view. In
this case, the edits you have made are rendered into the audio file and cannot be changed
or undone the next time you open the audio file in the File Editor.
To save a project as an audio file
1 Choose File > Save As.
2 In the Save dialog, type a name for the file and browse to the location where you want
to save it.
3 Choose the file type for the project from the File Type pop-up menu.
You can save a project to any of the following standard audio file formats:
• AIFF
• WAVE
• NeXT
• Sound Designer II
• Core Audio File
• QuickTime Movie

Chapter 8 Working in the File Editor

247

4 Choose the bit depth for the project from the Bit Depth pop-up menu.
5 Choose the sample rate for the project from the Sample Rate pop-up menu.
6 Optionally, select any of the following checkboxes:
• Dither: Select to dither the file. Dithering is useful when saving a project at a lower bit
depth or sample rate. In general, you should dither a project only when saving it as a
standard audio file, and only when you have finished all bit depth or sample rate
conversions. Dithering is not appropriate for 32-bit files.
• Include Source Audio: Select to include the source audio in the project. If you don’t
select this checkbox, the project refers to the external source audio file. Referenced
files must be present to open the project correctly.
• Save Flattened Copy: Select to additionally update the linked flat file. Saving a flattened
copy enables integration with applications that do not support .stap files.
7 Click Save.

Note: When you save an audio file with the same name, location, and extension as the
original audio file, you overwrite the existing audio file.

Using the Timeline Controls in the File Editor Project View
You can use the Timeline controls, located at the lower-left corner of the project pane,
while working in the File Editor project view.
Some of these controls have slightly different functions in the File Editor than they do in
the Timeline.
• Master Envelopes button: You can show or hide the envelopes for the audio file.
• Snapping button: You can turn snapping on or off in the File Editor.
• Snap To button: You can choose the Snap To value that the playhead and other items
snap to. In the File Editor, the choices for snap are Ruler Ticks and Zero Crossings.

248

Chapter 8 Working in the File Editor

• Track Height control: This sets the height of the envelope rows when you show envelopes
in the File Editor.

Scripting Actions in the File Editor Project View
You can save a series of actions in the File Editor project view as an AppleScript droplet
and use the droplet to modify other audio files. You can apply the actions in a saved
droplet while you are working in Final Cut Pro using the Send To shortcut menu. You can
also drag files or folders onto a droplet, making it easy to batch process files.
You can edit the droplet in the AppleScript Script Editor to adjust action settings. This is
especially helpful when you want to apply the same series of actions to multiple files, or
when you want to apply actions repeatedly, changing one or several settings each time.
You can apply a droplet to another audio file, or group of files, by dragging files or folders
containing a group of files onto the droplet.
To save a series of actions as a droplet
1 Open an audio file in the File Editor.
2 Apply the actions to the audio file.
3 Choose File > Save as AppleScript.
4 In the Save dialog, type a name for the droplet.
By default, droplets are saved to the location
/Users/username/Library/Scripts/Soundtrack Pro Scripts/. Do not change the location or
Soundtrack Pro and Final Cut Pro may not be able to find and use your saved droplets.
You can apply a series of actions saved as a droplet to a clip in Final Cut Pro.

To apply a saved droplet to a clip in Final Cut Pro
In the Final Cut Pro Timeline or Bin, Control-click the clip, choose Send To > Soundtrack Pro
Script from the shortcut menu, then choose the droplet you want to apply from the
submenu.
Soundtrack Pro opens with the clip visible in the File Editor. The actions are applied to
the clip, the clip is saved with the changes, and the File Editor moves to the background,
behind the Final Cut Pro windows.

Using the Global Waveform View
The File Editor includes a Global Waveform view, located directly above the main waveform
display. The Global Waveform view displays a miniature view of the entire audio file and
shows the current playhead position. The part of the audio file visible in the waveform
display appears inside a blue rectangle. You can quickly move to different parts of the
audio file by dragging the visible area rectangle.

Chapter 8 Working in the File Editor

249

To move to a different part of the audio file using the Global Waveform view
Drag the blue visible area rectangle to a new position.
Drag this rectangle
to a new position.

Using Markers in the File Editor Project View
You can insert markers in an audio file project in the same way as in a multitrack project.
Markers can be useful for indicating where a specific sound, cue, or event begins or ends
in the audio file. They can also be useful for indicating an area of an audio file you want
to time stretch.
When an audio file project has two or more markers, you can select the area between
two markers by double-clicking in the waveform display. For more information, see
Selecting All or Parts of an Audio File.
For information about inserting, naming, moving, and deleting markers, see Working
with Markers.

Processing Audio Files

You can process audio files in the File Editor in a variety of ways. You can choose
processing effects and other operations from the Process menu and apply them to an
entire file, or select part of the file and apply the effect to the selection. When you choose
an item from the Process menu, the item appears as an action in the Actions list. The
Process menu contains the items described in the following sections.
Note: In addition to processing effects, you can apply realtime effects to an audio file
project. You can apply realtime effects in the Effects tab, and you can automate realtime
effect parameters in the File Editor project view. For more information, see Applying
Realtime Effects in the File Editor Project View.
This chapter covers the following:

Choosing Processing Effects
The Effects submenu contains an extensive set of professional audio effects you can apply
to an audio file or a selection. The audio effects in the Effects submenu are the same as
the realtime effects you can apply to tracks, busses, and submixes in the Timeline. For
information about individual effects in the Effects submenu, see Audio Effects Included
with Soundtrack Pro and the Soundtrack Pro Effects Reference document, available in the
Help menu.
The effects included with Soundtrack Pro are categorized by type in the Effects submenu.
Below these effect categories is a submenu for Mac OS effects. If you have installed
third-party Audio Units effects on your computer, additional submenus for the third-party
effects appear at the bottom of the Effects submenu.
When you apply a processing effect from the Effects submenu, the floating advanced
settings window for the effect appears. Processing effects windows are nonmodal, allowing
you to click a window behind the effects window (for instance, the Timeline or File Editor
window) to move the playhead or adjust the selection range.
The advanced settings window contains controls for previewing the effect in the File
Editor, bypassing, applying, or canceling the effect, resetting effect parameters, and
applying effect presets.

Fade In
Choosing this command fades in the audio file or selection. The fade-in progresses in
linear fashion from the beginning to the end of the audio file or selection.

Fade Out
Choosing this command fades out the audio file or selection. The fade-out progresses in
linear fashion from the beginning to the end of the audio file or selection.

Normalize
Choosing this command normalizes (adjusts the gain of ) the audio file or selection to the
decibel level shown in the Normalization Level field. There are two different methods
you can use to normalize an audio file or selection: Peak (the default) or RMS (root mean
square). If you choose the peak method, the highest peak in the file or selection is raised
or lowered to the level you set, and the rest of the audio file is raised or lowered by the
same amount. If you choose the RMS method, the average level in the file or selection is
raised or lowered to the level you set. In general, use the peak method if you wish to set
the loudest part of your selection to a particular value, and use RMS if you wish to set the
average decibel level to a more consistent perceived volume. When you choose Process
> Normalize, the level is set to 0 dB by default.

You can preview the audio file at the normalization level before closing the Normalize
dialog. This makes it easy to set the level before normalizing the file.

To preview the file at the normalization level
In the Normalize dialog, select the Preview checkbox.

Adjust Amplitude
Choosing this command raises or lowers the gain of the audio file or selection by the
amount shown in the Amplitude Level field. When you choose Process > Adjust Amplitude,
the level shown in the field is zero (0) dB, or unity gain.

Noise Reduction
Some audio files contain unwanted noise, making it difficult to hear the voices, music, or
other content of the file. Soundtrack Pro features two commands, Set Noise Print and
Reduce Noise, that you can use together to reduce noise in an audio file or selection.

Set Noise Print
The Set Noise Print command lets you select part of an audio file containing only the
noise that you want to remove as a “noise print.” The noise print provides a signature of
the frequencies to reduce or remove from the file.
Setting the noise print before reducing noise is optional. If you do not set a noise print
before using the Reduce Noise command, Soundtrack Pro extracts a noise print from the
selected part of the audio file. If there is an existing noise print, it will be used, even if it
is from a different audio file, unless you set a new noise print.
To set part of an audio file as a noise print
1 In the waveform display, select the part of the audio file containing only the noise you
want to reduce.
2 Choose Process > Noise Reduction > Set Noise Print.
The selected noise is stored as a noise print.
Note: The noise print is saved along with the Soundtrack Pro project, allowing you to use
different noise prints in different projects without saving presets. If you wish to work with
multiple noise prints in a single project, or across multiple projects, see Save a Noise Print
Preset.

258

Chapter 9 Processing Audio Files

Save a Noise Print Preset
In a normal workflow, Soundtrack Pro only stores a single noise print at a time. Every time
a new noise print is set, any previous noise print is overwritten. If you wish to work with
multiple noise prints, each one must be saved as a preset.
To save a noise print preset
1 In the waveform display, select the part of the audio file containing only the noise you
want to reduce and save as a preset.
2 Choose Process > Noise Reduction > Set Noise Print.

3 In the Reduce Noise dialog that appears, you can optionally set the following:
• The noise threshold: The noise threshold determines the level below which audio in the
noise print is considered to be noise. Lowering the threshold results in only very low
signals being reduced, while raising the threshold results in more high-level signals
being reduced.
• The tone for noise reduction: The Tone Control slider controls whether low-frequency
content (bass) or high-frequency content (treble) is preserved during noise reduction.
You can also preview the noise reduction with the dialog open.

Adding Ambient Noise
When editing an audio file, you may want to remove some sounds from the file while
preserving the room tone or other ambient background noise in the file. Soundtrack Pro
features commands you can use to set a selection as an ambient noise print and add the
noise print to existing audio or replace the audio with the noise print.

Set Ambient Noise Print
The Set Ambient Noise Print command lets you copy part of an audio file containing only
ambient noise that you want to add to another part of the file (or another file).
To set part of an audio file as an ambient noise print
1 In the waveform display, select the part of the audio file containing only ambient noise.
2 Choose Process > Set Ambient Noise Print.
The ambient noise is stored in a special buffer separate from the Clipboard and is saved
to the project.
If you have copied audio to the Clipboard, you can set the contents of the Clipboard as
an ambient noise print.

To set the contents of the Clipboard as an ambient noise print
Choose Process > Set Ambient Noise From Clipboard.

Add Ambient Noise
The Add Ambient Noise command adds the ambient noise stored in the ambient noise
buffer to the audio file or selection.
To add ambient noise to an audio file
1 In the waveform display, select the part of the audio file to which you want to add the
ambient noise.
2 Choose Process > Add Ambient Noise.
The ambient noise is added to the selected audio. If the selection is longer than the copied
ambient noise, the ambient noise repeats to fill the selection.

ambient noise, the ambient noise repeats to fill the selection.

Equalization Matching
Equalization matching matches the average frequency spectrum of the target clip to that
of the source clip.

Set Equalization Print
The Set Equalization Print command lets you select part of an audio file and create an
equalization print from it. The equalization print provides an equalization signature that
you can apply to other parts of the same file. To match parts of a different file, use the
Multitrack Editor. For more information on using equalization prints in the Multitrack
Editor, see The Lift and Stamp Tools and the Sound Palette.
To set an equalization print
1 Select the part of the audio file containing the equalization you want to match.
2 Choose Process > Equalization Matching > Set Equalization Print.
The selection is stored as an equalization print.
Note: Only one equalization print can be saved at a time. If you set a new equalization
print, the last one is overwritten.

Apply Equalization

print to match the equalization in the audio file or selection.
To match equalization using the equalization print
1 Select another part of the audio file in which you want to match the equalization.
2 Choose Process > Equalization Matching > Apply Equalization.
The equalization print is applied to the selection.

Convert to Mono
Choosing this command converts a stereo audio file to mono. You can choose whether
to convert the file to mono by using only the left channel, using only the right channel,
or combining the two channels. Combining the left and right channels sums them as an
equal gain mix.

Working with Audio Effects

You can modify the sound of your project in many ways using audio effects. Soundtrack Pro
includes a complete set of professional-quality audio effects you can use in your projects.
This chapter covers the following:
• Processing Effects and Realtime Effects (p. 267)
• Working with Effect Presets (p. 269)
• Audio Effects Included with Soundtrack Pro (p. 270)
• Working with Realtime Effects (p. 283)
• Working with Processing Effects (p. 293)

Processing Effects and Realtime Effects
Soundtrack Pro gives you two ways to use audio effects in your projects: processing effects
and realtime effects. Audio effects can be applied as processing effects to entire audio
clips or regions of audio clips, resulting in nondestructive actions that can be adjusted
at any time. Audio effects can also be applied to tracks, submixes, and busses as realtime
effects, enabling parameters of the effects to be automated so that they change over
time.
The same audio effect can be applied either as a realtime effect or a processing effect,
with different results.

Applying Processing Effects
You can apply processing effects to clips and regions of clips in the multitrack Timeline
as well as to audio file projects (or regions thereof ) in the File Editor. The Process menu
includes an Effects submenu where you choose processing effects to add to your project.
Processing effects are added as actions, which you can turn on or off, reorder, and adjust
in the Actions list.
To apply a processing effect to a clip in the Timeline
1 In the Timeline, select one or more clips, or portions of one or more clips.

267

For more information about selecting clips, see Selecting Audio Clips in the Timeline and
Editing with the Timeslice Tool.
2 Choose Process > Effects and choose one of the effects from the submenu.
The effect’s advanced settings window appears.

Advanced settings
windows can contain
different kinds of
controls.

You can adjust the effect’s parameters by moving the controls in the window. Each
advanced settings window may have unique controls in addition to sliders, buttons, and
value fields.
For detailed information on adjusting the parameters of specific effects, see the
Soundtrack Pro Effects Reference document, available in the Help menu.
4 Optionally, do any of the following:
• Click the Play button to hear the effect and your adjustments to it.
• Click the Reset button to reset the parameters to their default values.
• Click the Toggle Effect Bypass button to hear the audio without the effect.
• Click the Show Presets button to display the available presets.

Chapter 10 Working with Audio Effects

A corresponding action appears in the Actions tab for the clip.
For more information about working with processing effects, see Processing Audio Files.
For information on working with actions, see Working with Actions.

Applying Realtime Effects
You can add realtime effects to entire tracks, busses, and submixes in a multitrack project
or to an entire audio file project. You can automate realtime effects parameters to create
changes over time. Realtime effects modify the audio as it passes through them, so you
hear any changes you make, or any new audio you add, through the sound of the effect.
Each realtime effect has effect parameters you can adjust to control how the effect
modifies the audio.
You can create effects chains on a track, bus, submix, or audio file using realtime effects.
An effects chain is a series of effects that modify the audio in a set order. Using busses in
the Timeline and Mixer, you can create submixes, and apply the effect to all the tracks in
a submix with one set of controls.
For information on working with realtime effects in both multitrack and audio file projects,
see Working with Realtime Effects.
Note: This chapter describes the various categories of effects included with Soundtrack Pro.
For complete information on the details of each realtime effect, see the Soundtrack Pro
Effects Reference document, available in the Help menu.

Rendering Realtime Effects to Actions
You can also convert any realtime effect that you have applied in the File Editor project
view to an action in the Actions list, which enables you to turn these effects on or off,
reorder them in the list, and save them with the audio file project. For more information,
see Working with Realtime Effects.

Working with Effect Presets
Many effects come with several combined parameter settings called presets. Presets are
a handy way to get up and running with Soundtrack Pro effects without having to learn
a lot of details about their various parameters. For example, the MatrixReverb effect (in
the Mac OS category) has presets for various sizes of room, hall, and chamber settings,
as well as Plate reverb and Cathedral settings. If an effect has presets, the presets appear
in a Factory Presets pop-up menu in the list of effect parameters.
You can show an effect’s presets, add and delete presets, apply a preset, adjust preset
parameters, and create your own presets.

To show effect presets from the advanced settings window
Click the Show Presets button in the advanced settings window.

Audio Effects Included with Soundtrack Pro
Soundtrack Pro includes the following types of audio effects:
• Dynamics: Dynamics effects let you shape the volume of your projects over time.
Bundled dynamics effects include Compressor, Multipressor, Adaptive Limiter, Noise
Gate, Expander, and Limiter.
• Distortion: Distortion effects change the tone of the audio signal to re-create the sound
of overdriven tube amplifiers or digital distortion. Bundled distortion effects include
Bitcrusher, Clip Distortion, Distortion, Distortion II, Exciter, Overdrive, and Phase
Distortion.

270

Chapter 10 Working with Audio Effects

• EQ and Filter: EQ (short for equalization) effects let you change the level of selected
frequencies. EQ provides a powerful way of shaping the sound of your projects. Bundled
EQ effects include AutoFilter, Fat EQ, High Cut and Low Cut, High Pass and Low Pass
filters, Channel EQ, High and Low Shelving EQ, Linear Phase EQ, Match EQ, Parametric
EQ, and Soundtrack Pro Autofilter.
• Modulation: Modulation effects delay an audio signal and shift (modulate) when the
delayed signal plays back relative to the original signal. Bundled modulation effects
include Chorus, Ensemble, Flanger, Modulation Delay, Phaser, Scanner Vibrato, and
Tremolo.
• Reverb and Delay: Reverb effects can be used to simulate the sound of acoustic spaces,
both realistic and unnatural. Delay effects can be used to add echoes and other recurring
sounds. Bundled reverb and delay effects include PlatinumVerb, Soundtrack Pro Reverb,
Stereo Delay, Tape Delay, and Space Designer, a powerful tool for sound design.
• Meters and Diagnostic: You can use realtime diagnostic effects to clean up audio files
in a variety of ways, including pitch, intensity, and phase problems. Bundled diagnostic
effects include Correlation Meter, MultiMeter, Test Oscillator, and Tuner. These are only
available as realtime effects, not processing effects.
• Miscellaneous: Miscellaneous effects fall outside the other categories, providing
additional ways to modify your audio. Bundled miscellaneous effects include Delay
Designer, Denoiser, Direction Mixer, Enveloper, Gain, Multichannel Gain, PitchShifter II,
Ringshifter, Spectral Gate, Stereo Spread, SubBass, Surround Compressor, and Vocal
Transformer.

Dynamics Effects
Dynamics effects let you adjust the dynamic range (the range between the softest and
loudest sounds) of your projects. You can use dynamics effects to make sounds more
focused and to optimize the sound for specific playback situations. Dynamics effects
include compressors, limiters, and noise gates.

Chapter 10 Working with Audio Effects

271

Compressors
Compressors work like an automatic volume control, lowering the volume whenever it
rises above a certain level, called the threshold. But why would you want to reduce the
dynamic level? By cutting the peak levels, the compressor lets you raise the overall volume
of the signal. This gives the sound more focus by making the foreground parts stand out
while preventing the background parts from becoming lost in the mix. Compression also
tends to make sounds tighter or “punchier.” Because the peaks are lower, the maximum
volume is reached more quickly.

Compressor plug-in

In addition, a compressor can make a project sound better when played back in different
situations. For example, the speakers on a television set or in a car sound system typically
reproduce a narrower dynamic range than does the sound system in a theater.
Compressing the overall mix can help make the sound reproduce more clearly in
lower-fidelity situations.
Compressors have two main parameters. The threshold lets you set the amplitude above
which the compressor lowers the volume. The ratio lets you control the amount by which
sounds above the threshold will be lowered, as a percentage of the original signal.
For example, if you set the threshold to –12 dB, and the ratio to 2:1, a sound at –7 dB
(5 dB above the threshold) is reduced by 2.5 dB, and a sound at –2 dB (10 dB above the
threshold) is reduced by 5 dB.
Compressors can also include parameters for attack and release. These parameters let
you set how quickly the compressor reacts once the threshold is reached (for attack) or
once the signal falls below the threshold again (for release). Use these parameters to
make the compressor’s effect more subtle or more pronounced. Another parameter on
some compressors is the knee (or soft knee), which lets you control how gradually the
compressor transitions between no compression and the compression ratio at the
threshold.

272

Chapter 10 Working with Audio Effects

Compressors are typically used on vocal tracks to make the vocals prominent in the overall
mix. They can also be used on music and sound effects tracks, but are rarely used on
ambience tracks.
Limiters
Limiters (also called peak limiters) prevent the audio signal from exceeding a maximum
volume level. A compressor gradually attenuates levels above the threshold, but a limiter
puts a hard limit on any signal louder than the threshold, usually at a high ratio. You use
a limiter mainly to prevent clipping.
Noise Gates
A noise gate alters the signal in the opposite direction from a compressor. While a
compressor lowers the volume of sounds above the threshold, a noise gate lowers the
sounds below the threshold. Loud signals pass through unchanged, but softer signals,
such as the decay of a loud instrument, are cut off. Noise gates can be used to eliminate
low-level noise or hum from an audio signal.

Distortion Effects
Distortion effects simulate the sound of analog and digital distortion. After working to
eliminate the digital distortion caused by clipping from a project, why would you add
distortion as an effect? The distortion produced by overdriven vacuum tubes (which were
used in amplifiers and music recording equipment before the development of digital
recording technology) produces an effect which many people find pleasing, and which
is integral to many styles of popular music. Analog tube distortion adds a distinctive
warmth and bite to the signal.
There are also distortion effects that intentionally cause clipping and digital distortion of
the signal. These can be used to modify vocal, music, and other tracks to produce an
intense, unnatural effect, or for creating sound effects.
Distortion effects include parameters for tone, which let you shape the way in which the
distortion alters the signal, and for gain, which let you control how much the distortion
increases the output level of the signal.

EQ and Filter Effects
EQ is likely the most common audio effect used in post-production. You can use EQ to
shape the sound of a project by adjusting specific frequencies or frequency ranges. Using
EQ, you can create both subtle and extreme changes to the sound of your projects.
Most EQ effects make use of filters. As the name suggests, a filter allows certain frequencies
to “pass through” to the output while stopping or attenuating other frequencies. EQ
effects include highpass, lowpass, and band pass filters.

Chapter 10 Working with Audio Effects

273

When the audio signal passes through an EQ filter, the frequencies that pass through can
be raised or lowered in volume. Raising and lowering frequencies using EQ is often referred
to as boosting and cutting frequencies. You can create many changes to the sound of
your project by boosting and cutting various frequencies.

Channel EQ plug-in

Frequency Ranges Used with EQ
Sounds can be categorized into one of three basic frequency ranges: bass, midrange, or
high (also called treble). These can be further divided to include low bass, low and high
midrange, and low and high highs. The following table describes some of the sounds
affected by each range:

274

Name

Frequency range

Description

High High

8–20 kHz

Includes cymbal sounds and highest harmonics
of instruments. Boosting frequencies in this range
slightly can add sparkle and presence.

High

5–8 kHz

This range corresponds roughly to the treble tone
control on a stereo. Boosting frequencies in this
range can add brightness and shine.

Low High

2.5–5 kHz

Includes the higher harmonics of voices and
musical instruments. This range is important for
adding presence. Excessive boosting in this range
can sound shrill or harsh.

High Midrange

1.2–2.5 kHz

Includes the consonants of voices and the high
harmonics of musical instruments, especially brass
instruments. Excessive boosting in this range can
create a pinched, nasal sound.

Midrange

750 Hz–1.2 kHz

Includes the vowels of voices and the harmonics
of musical instruments that create tone color.

Chapter 10 Working with Audio Effects

Name

Frequency range

Description

Low Midrange

250–750 Hz

Includes the fundamentals and lower harmonics
of voices and musical instruments; careful EQing
of each can keep them from competing. Excessive
boosting in this range can result in muddy and
unclear audio; excessive cutting can produce
thin-sounding audio.

Bass

50–250 Hz

Corresponds roughly to the bass tone control on
a stereo. Includes the fundamental frequencies of
voices and of musical instruments. Excessive
boosting in this range can sound boomy and thick.

Low Bass

50 Hz and below

Also calledsub bass. Very little of the sound of
voices or musical instruments falls in this range.
Many sound effects used in movies, such as
explosions and earthquakes, fall in this range.

Note: The frequencies shown for each range are approximate. Any division of sound into
frequency ranges is somewhat arbitrary and is meant only to give a general indication
of each range.
Roll-Off Filters
The simplest types of EQ effects are roll-off filters, which include lowpass, highpass,
bandpass, and shelf filters. Lowpass filters affect all frequencies above a specific frequency,
called the cutoff frequency. Frequencies above the cutoff are attenuated or “rolled off”
gradually, usually by a fixed number of decibels per octave. Highpass filters, by contrast,
affect all frequencies below their cutoff frequency. Bandpass filters exclude all frequencies
close to their center frequency. You can set the center frequency, and also set the bandwidth
or Q, which specifies how wide a range of frequencies around the center frequency is
affected.
These EQs include parameters for setting the cutoff frequency. Shelf filters add parameters
to control the gain (the amount of boost or cut). You can use roll-off filters as “broad
brush” effects to boost or cut a large range of frequencies.
Graphic EQs
Graphic EQs give you a set of filters (often with 10 or 31 filters), each with a set center
frequency and bandwidth. Using a graphic EQ, you can shape a wide variety of frequencies
throughout the frequency range. Graphic EQs can be used to shape the sound of the
overall project mix.
Parametric EQs
Parametric EQs are similar to bandpass EQs, but provide a greater amount of control, and
can be used for extremely precise adjustments. With a parametric EQ, you can set the
center frequency, the gain, and the bandwidth. Used carefully, a parametric EQ can help
a track cut through the mix, or help a track or project sound fuller. Parametric EQs can
also be used to remove specific, unwanted frequencies from a mix.

Modulation Effects
Modulation effects begin with a delayed signal, like time-based effects, but vary (or
modulate) the delay time, typically using a low-frequency oscillator (LFO). This can be
used to double a sound, making it seem stronger and “fatter,” to simulate a group of
voices or instruments playing together, or to add a distinctive character to the sound.
Modulation effects include chorus, phase shifters, and flangers.
All of the modulation effects include parameters for the delay rate (also called speed or
frequency), which let you set the minimum delay time; depth (also called width or intensity),
which you use to set how much the LFO modulates the delay time; and mix, which you
use to control the ratio of the effected (wet) signal to the original (dry) signal. They can
also include parameters for feedback (or regeneration), which add part of the output back
into the input signal.
Chorus
Chorus effects play back multiple repetitions of the delayed signal (like reverbs), but vary
the delay time for each one, using an LFO. As the name implies, this effect can strengthen
the sound, and create the impression that the sound is being played by many instruments
or voices in unison. The slight variations in delay time created by the LFO simulate the
subtle differences in timing and pitch heard when several people play together. Using
chorus also adds fullness or richness to the signal and can add movement to low or
sustained sounds.
Phase Shifters
Phase shifters produce a characteristic “whooshing” sound by combining the original
signal with a copy of the signal that is slightly out of phase with the original. This means
that the amplitudes of the two signals’ sound waves reach their highest and lowest points
at slightly different times. The time between the two signals is modulated, typically using
an LFO. As the two signals go in and out of phase, certain frequencies, called notch
frequencies, are created, which give phase shifters their distinctive sound.
The main difference between chorus and phase shifting is the amount of delay time.
Chorus effects typically use delay times between 20 and 30 milliseconds (ms), while phase
shifters (and flangers, discussed next) typically use shorter delay times, between 1 and
10 ms.
Flangers
Flangers work in much the same way as do phase shifters, but additionally change the
pitch of the delayed signal slightly. Flanging is typically used to create a more extreme
change than phase shifting, sometimes described as adding a “spacey” or “underwater”
effect.

276

Chapter 10 Working with Audio Effects

Reverb and Delay Effects
Reverbs and delays work by copying a part of the audio signal, delaying it for a brief
period of time, and then playing it back with the original signal. The delayed signal can
be played back multiple times and can be modified in a variety of ways.
Delay
A delay effect stores the audio signal and then plays back each repetition at a regular
rate of time after the original signal. Delays can be used to double individual sounds (for
example, making it sound as if a group of instruments is playing the same melody), to
achieve echo effects (making it sound as though the sound was occurring in an immense
space), and to enhance the stereo position of tracks in a mix. Delay effects are not
commonly used on an overall mix except to achieve special effects (such as to create an
“otherworldly” sound).
Delay effects let you set the delay time, the time between the original signal and the
delayed signal. Delays often provide parameters for feedback (also called regeneration),
which let you set how much of the delayed signal is fed back into the delay’s input,
creating more repetitions of the delay (like the number of “bounces” in an echo). Specific
types of delay have other parameters: tap tempo delays let you set the delay time by
physically tapping a key or controller; stereo delays include parameters for the pan position
of the output signal, which can be shifted over time using a low-frequency oscillator
(called an LFO).

Chapter 10 Working with Audio Effects

Reverb
Reverberation, usually shortened to reverb, simulates the sound of acoustic environments
such as rooms, concert halls, caverns, or the sound of infinite space. In any acoustic space,
sounds echo off the surfaces of the space (the floor, walls, and ceiling) over and over,
gradually dying out until they become inaudible. Reverb effects consist of thousands of
delays, of varying lengths and intensities, that simulate these natural echoes. Reverb helps
define the sense of space in which sounds take place and can be used to simulate both
realistic and fantastic acoustic environments.

Space Designer plug-in

The first form of reverb actually used a room with hard surfaces (called an echo chamber)
to add echoes to the signal. Mechanical devices, including plates and springs, were also
used to add reverberation to the output of instruments and microphones. Digital sound
recording has made it possible to use digital reverbs, which use complex algorithms (sets
of equations) to simulate various acoustic environments with greater accuracy and
flexibility.
Simple reverb effects provide parameters for the decay time or reverb time, which let you
set how long the reverb lasts before dying away, and the mix or level, which you use to
set the ratio of the effected signal (called the wet signal) to the original (the dry signal).
More sophisticated reverbs can include the following parameters:
• Room type: Lets you set the type of space the reverb will simulate: a small or large
room, a hall, or another type of acoustic space.

278

Chapter 10 Working with Audio Effects

• Predelay time: In an acoustic space, there is a short period of silence between a sound
and the time when the initial echoes of the reverb begin. Different spaces have different
amounts of predelay, which helps “tell” our ears how large the space is. Longer predelay
settings also help separate the original (dry) signal from the effected (wet) signal, making
it sound clearer and sometimes larger.
• Early reflections: The first echoes to arrive from the surrounding surfaces in a space are
determined by the size and shape of the space, and “tell” our ears what type of space
it is.
• Diffusion: Lets you set the number of the echoes in the reverb. Hall reverbs typically
have low diffusion settings, while plate reverbs typically have high diffusion settings.
• High-frequency and low-frequency reverb time: These parameters let you specify the
decay of higher and lower frequencies separately. Different surfaces, such as wood
floors and concrete walls, absorb high and low frequencies at different rates, and these
parameters let you simulate the sound of different environments more closely.
• Reverb envelope: Lets you control how much the volume of the reverb changes over
time. In natural acoustic situations, the reverb echoes decay gradually over time. You
can re-create this gradual decay, or gate the reverb so that it cuts off more abruptly.

Meters and Diagnostic Effects
Diagnostic effects help you analyze and clean up audio in a variety of ways. Each type of
diagnostic effect provides a different way to “look at” an audio clip or file, and each has
a unique set of parameters. These effects are available only as realtime effects in the
Effects tab and the Mixer, not as processing effects.
Correlation Meter
The Correlation meter displays the phase relationship of a stereo signal. A correlation of
+1 (plus one, the far right position) means that the left and right channels “correlate”
100% (that is, they are completely in phase). A correlation of 0 (zero, the center position)
indicates the widest permissible left/right divergence, often audible as an extremely wide
stereo effect. Correlation values less than zero indicate that out-of-phase material is
present, which can lead to phase cancelations if the stereo signal is combined into a
monaural signal.
MultiMeter
The MultiMeter combines the functions of the Level Meter and Correlation Meter (as
described above) with several other analysis tools:
• A Spectrum Analyzer
• A Goniometer for judging the phase coherency in the stereo sound field

Chapter 10 Working with Audio Effects

279

The control panel to the left of the display allows you to switch between the Analyzer
and Goniometer and contains parameter controls for the MultiMeter. The Stereo Level
and Correlation Meter are always visible.

MultiMeter with Spectrum Analzyer active

Spectrum Analyzer
The Spectrum Analyzer divides the audio signal into 31 independent frequency bands.
Each frequency band represents one third of an octave. The filter curves comply to IEC
document 1260.
You turn on the Spectrum Analyzer by clicking the Analyzer button. Turning on the
Spectrum Analyzer turns off the Goniometer. The four buttons under the Analyzer button
determine what portion of the input signal the Analyzer is displaying. You can choose
between Left or Right channel only. LR max shows the maximum band levels of either
channel, while Mono displays the levels of the stereo signal summed to mono.
The View options determine the level represented by the top line of the scale in the
display (Top; range: -40 to +20 dB) and the overall dynamic range of the Spectrum Analyzer
(Range; range: 20 to 80 dB). These two parameters can also be set directly in the display:
by dragging directly on the bar graph, you can shift the top line of the display. Dragging
directly on the dB scale allows you to compress or expand the scale’s range. The View
options are useful when analyzing highly compressed material as you can identify smaller
level differences more easily by moving or reducing the display range.
There are three display respond modes: RMS Slow, RMS Fast, and Peak. RMS Slow and
RMS Fast modes show the effective signal average (Root Mean Square) and offer a good
representation of the perceived volume levels. Peak mode shows level peaks accurately.

280

Chapter 10 Working with Audio Effects

Goniometer
The Goniometer helps you to determine the coherence of the stereo image. Using the
Goniometer, you can see phase problems as trace cancelations along the center line
(M=mid/mono). Goniometers developed when early two channel oscilloscopes first
appeared. Users would connect the left and right stereo channels to the X and Y inputs
while rotating the display by 45 degrees, resulting in a useful visualization of the signal’s
stereo phase.

MultiMeter with Goniometer active

The signal trace slowly fades to black, imitating the glow of the tubes found in older
Goniometers, and at the same time enhancing readability.
Clicking the Goniometer button turns on the Goniometer and turns off the Spectrum
Analyzer. You can use the Auto Gain display parameter in order to obtain a higher readout
on low-level passages. Auto Gain allows the display to automatically compensate for low
input levels. You can set the amount of compensation with the Auto Gain parameter, or
set Auto Gain by dragging directly in the display area of the Goniometer.
Note: Auto Gain is a display parameter only and increases the display for better readability.
The actual audio levels are not touched by this parameter.

Miscellaneous Effects
Miscellaneous effects don’t fall into any of the other categories. They include denoising
effects, pitch shifting effects, stereo enhancers, bass enhancers, and effects used to
transform the sound of vocals. Each effect gives you a different way to modify the audio,
and includes a unique set of parameters.

Chapter 10 Working with Audio Effects

281

Denoiser
Using the Denoiser, you can eliminate or reduce many kinds of low-level noise (noise
floor) from an audio signal. The main parameters of the Denoiser are Threshold, Reduce,
and Noise Type. The Threshold parameter sets how high the noise floor is for the audio
signal. The recommended method for setting the Threshold is to find a passage where
you hear only noise, then set the Threshold so that signals at this volume level are filtered
out.
The Reduce parameter sets the level to which the noise floor is reduced. You use the
Noise Type parameter to set the type of noise that the Denoiser reduces. There are three
choices of noise type:
• Setting the Noise Type to 0 (zero) causes the Denoiser to reduce “white noise” (all
frequencies reduced equally).
• Setting the Noise Type to a positive value causes the Denoiser to reduce “pink noise”
(harmonic noise; greater bass response).
• Setting the Noise Type to a negative value causes the Denoiser to reduce “blue noise”
(hiss, sibilants, tape noise).
The Denoiser recognizes frequency bands with a lower volume and less complex harmonic
structure, and then reduces them to the desired dB value. This method is not completely
precise, and neighboring frequencies are also reduced. Using the Denoiser at too-high
settings can produce the “glass-noise” effect, which is usually less desirable than the
existing noise.
There are three smoothing parameters that you can use to minimize the “glass-noise”
effect: Frequency smoothing, Time smoothing, and Level smoothing. Raising the Frequency
smoothing slider results in a smoother transition of denoising to the neighboring
frequencies. When the Denoiser recognizes that only noise is present in a certain frequency
band, the higher the Frequency Smoothing parameter is set, the more it will also change
the neighboring frequency bands to avoid glass noise.
By adjusting the Time smoothing slider, you can set the amount of time the Denoiser
takes to reach maximum noise reduction. By adjusting the Level smoothing slider, you
can set a factor for a smoother transition between adjacent volume levels. When the
Denoiser recognizes that only noise is present in a certain volume range, the higher the
Transition smoothing parameter is set, the more it will also change similar level values
to avoid glass noise.

Chapter 10 Working with Audio Effects

Stereo Spread
The Stereo Spread plug-in is a useful effect for sound design or audio clean-up. It enhances
the perception of stereo by extending the stereo base. Some stereo enhancing algorithms
function by changing the phase of the signal, which can distort your mix and produce
unpredictable results. Instead, the Stereo Spread plug-in extends the stereo base by
distributing a selectable number of bands in the middle frequency range alternately left
and right. This increases the perception of stereo without causing unnatural-sounding
distortion of the mix.
The main parameters of the Stereo Spread plug-in are Order, Upper Intensity (Upper Int.),
and Lower Intensity (Lower Int.). The Order parameter determines number of frequency
bands into which the signal is divided. The Upper Intensity parameter controls the intensity
of the base extension of the upper frequency bands. The Lower Intensity parameter
controls the intensity of the base extension of the lower frequency bands.
Human beings perceive stereo placement of sounds mainly in the middle and high
frequencies. If very low frequencies are distributed between the left and right speakers,
the energy distribution for both speakers will be significantly worse. Therefore, it is always
best to select a lower intensity setting for the lower frequency bands, and avoid setting
the Lower Freq. below 300 Hz.

Working with Realtime Effects
You can add realtime effects to a track, bus, submix, or the Master bus in a multitrack
project, or to an audio file project, and then adjust the effect parameters to control the
way in which the effects alter the sound of the track or project.

Important: Some effects, including reverb and delay, add audio that extends past the
end of the file. This is called an effect tail. When you export a project mix, or export a
track, bus, or submix with an effect that produces a tail, the exported file is lengthened
to include the effect tail until the point at which the tail falls below –96 dB. Also, when
you choose Process > Render To Action for an audio file project with a realtime effect
that produces a tail, the rendered project is lengthened to include the effect tail until the
point at which the tail falls below –96 dB.

Adjusting Realtime Effect Parameters
Once you’ve added a realtime effect, you can adjust the effect parameters to change the
way the effect alters the sound of the track, bus, submix, or audio file project. Each type
of effect has its own parameters, as discussed earlier. Many realtime effects have an
advanced settings window. The advanced settings window appears as a floating window
with related controls grouped together, and may provide an appearance that simulates
a hardware effects device. Effects with an advanced settings window have an Advanced
button at the top of the Effect Parameters area in the Effects tab.
Note: Generally, you use the advanced settings window to make adjustments to the
effect. While you can also make adjustments in the Effect Parameters area of the Effects
tab, its primary purpose is to enable automation, to chain, reorder and bypass effects,
and to add and adjust sends.
To adjust realtime effect parameters in the advanced settings window

Chaining and Reordering Realtime Effects
You can add more than one realtime effect to a track, bus, submix, or audio file project.
Adding multiple effects to an effects chain is called chaining effects.
When you add multiple effects, the effects are applied in sequence, meaning that the
output of the first effect becomes the input for the next effect, and so on, for each effect
in the chain. The order in which effects are applied is important, because each alters the
input signal, which includes the output of previous effects in the chain. You can reorder
effects and hear the difference in the way they alter the sound.

Using the Multitake Editor

The Multitake Editor presents a new way of dealing with layered audio clips. You use the
Multitake Editor to edit multitake (multiple-take), synchronized audio that is created by
performing multiple-take recordings (such as in automatic dialogue replacement, or ADR).
With this flexible tool, you can mix and match parts of different takes and make
adjustments at any time. Once you are done editing a multitake clip, you can collapse it
into a single (composite) clip, hiding the constituent edits that are not relevant to the
surrounding multitrack Timeline, and move it anywhere in your project as a single item.

This chapter covers the following:

What Is Automatic Dialogue Replacement?
Automatic dialogue replacement (ADR) is a process of re-recording dialogue in the studio
in synchronization with the picture. There are at least three roles in the ADR process: the
actor, the recording engineer, and the sound editor. The actor has to recreate his or her
performance and perfectly match up his or her speech to that of the film. The recording
engineer has to recreate acoustic spaces so that it doesn’t sound like an actor is in a
recording studio. The sound editor has to pick and choose the best parts of multiple
takes, combine them into one composite clip, and keep everything synchronized to the
picture. The Multitake Editor in Soundtrack Pro was created to address the needs of the
sound editor in this scenario.

Multitake Clips
A multitake clip is a “layered” audio clip. This means it contains multiple versions or “takes”
of the same audio material, such as a line of dialogue. Generally, these takes represent
overlapping spans of time in your program. In an ADR recording session, an actor may
repeat the same line many times. A single multitake clip can contain all of those takes as
distinct items.

Creating Multitake Clips
You can create a multitake clip by either recording one or converting a standard clip to
a multitake clip.

Recording Multitake Clips
For information about recording multitake clips, see Recording Multiple Takes.

Converting Standard Clips to Multitake Clips
You can convert any clip to a multitake clip.
To convert a standard clip to a multitake clip
1 Select a clip in the Timeline.
2 Do one of the following:
• Control-click the clip, then choose Convert to Multitake Clip from the shortcut menu.
• Select the Multitake tab and click the Make Multitake Clip button that appears in the
center of the Multitake tab.
The new multitake clip appears in the Multitake Editor.
3 Add any additional takes, as needed.
For information on adding takes, see Adding and Deleting Takes.

Chapter 11 Using the Multitake Editor

Overview of the Multitake Editor
You can think of the Multitake Editor as a simplified multitrack Timeline that is focused
entirely on the contents of a single multitake clip. In the Multitake Editor, you can audition
and choose which take will be used for each section of dialogue. The top row in the
Multitake Editor is the comp (or composite) track. This track represents a combination of
all of the edits that you make in the Multitake Editor. The other tracks represent individual
takes. You use the Blade tool to split the takes into regions. Use the Selection tool to
select the active take for each region. Use transition points to adjust the timing and to
create crossfades between the selected portions of takes.

Editing in the Multitake Editor
Fundamentally, there are three steps in making any multitake edit: splitting, selecting,
and adjusting.
• Stage 1: Splitting the Takes into Regions Using the Blade Tool
• Stage 2: Selecting the Active Take for Each Region
• Stage 3: Adjusting the Timing and Creating Crossfades

Stage 1: Splitting the Takes into Regions Using the Blade Tool
When you use the Multitake Editor, a take must be divided into regions.
To split a take using the Blade tool
1 Select the Blade tool by clicking the Blade tool in the upper-left corner of the Multitake
Editor (or by pressing B).

298

Chapter 11 Using the Multitake Editor

2 Click one of the take tracks using the Blade tool pointer.

Click a take track using
the Blade tool to create
a transition point.

A transition point appears in the Multitake Timeline at the point where you clicked.

Stage 2: Selecting the Active Take for Each Region
You can select active regions in the Multitake Editor with the Selection tool.
To select an active take for a region
1 Select the Selection tool by clicking the Selection tool in the upper-left corner of the
Multitake Editor (or by pressing A).
2 In the region, click the take track you want to select.

Select the take track
to make it the active
take for that region.

The take you clicked becomes the active take for that region.

Stage 3: Adjusting the Timing and Creating Crossfades
In this stage, you’ll use transition points to adjust the timing and to create crossfades
between the selected portions of takes. Slip (offset) take regions to synchronize them
with the picture.
To adjust a transition point
Do one of the following:

Drag the vertical transition point line left or right to adjust the timing of the cut.

Chapter 11 Using the Multitake Editor

299

Drag the left or right arrow handle at the top of a transition point to create a crossfade
between two takes, then double-click the fades to use the Fade Selector.

Drag the transition point
handles to create a
crossfade between takes.

You can also adjust the fade type by double-clicking either part of the crossfade. For more
information on fade types, see Creating Fade-Ins and Fade-Outs in the Timeline.
To delete a transition point
1 Select the vertical transition point line.
2 Press Delete.

Slipping Take Regions
Because it’s common for a particular take to be good but out of sync, you can slip (offset)
an individual take region.
To slip a take region
1 Command-Option-click the take region.
2 Without releasing the mouse button, drag to the left or to the right.
For more information about slipping (the offset of ) a take region, see Changing the Offset
of an Audio Clip.

Adding and Deleting Takes
You can easily add audio files to a multitake clip. Added takes can be any audio files that
Soundtrack Pro supports. The takes do not have to be from the same recording session.
It is just as easy to remove takes from a multitake clip. The sample rate and the channel
valence (mono, stereo, surround, and so on) of the files you want to add must match the
sample rate and the channel valence of the files already in the Multitake Editor.

Renaming Takes
By default, Soundtrack Pro names takes according to the order in which they were recorded
and the track in which they were recorded, for example, “Take 3 - Track 1 Recording 3.aiff.”
You can easily rename any take to suit your needs.

To rename a take in a multitake clip
Click the name field in the header for the take and enter a new name.

Reordering Takes
You can vertically rearrange the order of takes in a multitake clip.

Example: A Multitake Editing Workflow
The following example demonstrates how you might create a comp from multiple takes
of an ADR session using the Multitake Editor. In this case, there are four takes of the same
line: “Would you like to try a sample of our organic Peruvian blend?”
To edit multiple takes of a line of dialogue using the Multitake Editor
1 Select the multitake clip in the Timeline.
2 Control-click the ruler at the top of the multitrack Timeline, then choose Cycle Region
from the shortcut menu and Create Cycle Region from Selection from the submenu (or
press Shift-A).
3 Click the Multitake Editor tab to open it.
The comp track and, in this example, four take tracks, appear in the Multitake Editor.
4 Click the Solo button on the Take 1 track and click the Play button to listen to the first
take.
Take 1 plays.
5 Repeat this playback for each take to familiarize yourself with how they sound.
6 Optionally, you can choose to add a take from the original sync-sound production audio
to use a guide track. (See Slipping Take Regions for more information.)
7 When you are ready to make the first cut, click the Blade tool in the upper-left corner of
the Multitake Editor (or press B).
In this example, Take 3 contains the best version of the first couple of words.
8 Using the Blade tool, click just after the waveform for the second word in the Take 2 track.

Chapter 11 Using the Multitake Editor

Basic Mixing in Soundtrack Pro

Soundtrack Pro gives you the tools to create sophisticated audio mixes for your projects.
When you have added audio clips to your project and placed them in the Timeline, you
mix the project. Mixing is where you balance different elements, such as dialogue, music,
and sound effects, bring focus to key moments and events in the project, and create a
sense of perspective by placing sounds in space. When you finish mixing, you have one
or more final mixes that you can export.

Soundtrack Pro offers you professional mixing capabilities, including the abilities to create
busses and submixes and to send audio to multiple physical outputs. The Mixer provides
a visual representation of your project in a virtual mixing console, with channel strips
where you control different aspects of the sound. You can adjust volume and pan, mute
and solo tracks, choose track submixes, add effects, and observe levels as the project
plays. This chapter covers basic mixing. For information about mixing surround sound,
see Mixing Surround Sound.
This chapter covers the following:
• Steps in Mixing (p. 306)
• Structuring an Audio Post-Production Project (p. 306)
• Using the Mixer (p. 316)

305

Steps in Mixing
Mixing a project typically involves the following tasks:
• Balancing relative volume levels
• Panning tracks to create perspective
• Adding EQ, compression, and other processing using effects
• Using automation to create changes over time
• Setting the overall project volume and eliminating clipping
You can perform these steps in any order, and move back and forth between them as
you create the mix. In most situations, you finish mixing the individual tracks before
making changes to the overall project.
The following suggested order provides a guideline that may be useful for common
situations:
Stage 1: Mixing Main Dialogue Tracks
Solo the main voice tracks and pan to your liking. Add any EQ, compression, or other
processing. Adjust relative volume, leaving some headroom (typically around -6 dB) for
peaks in the signal, in case you need to raise levels later.
Stage 2: Mixing Other Dialogue and Middle Ground Tracks
With main voice tracks still soloed, solo the other dialogue, ADR, and voiceover tracks
one at a time and adjust volume and pan relative to the main voice tracks. Add any
processing if needed.
Stage 3: Mixing Background Tracks
With the previously mixed tracks still soloed, solo the background tracks one at a time
and adjust volume and pan relative to the other tracks. Add any processing if needed.
Stage 4: Making Changes to the Overall Mix
Once you have mixed all the individual tracks in your project, add any EQ, compression,
or other processing to the overall project. Adjust the overall volume to an appropriate
level and remove any clipping before exporting the project.

Structuring an Audio Post-Production Project
To organize their projects, most video and motion picture sound editors combine the
signals of related tracks and busses into submixes (also known as stem mixes). Then they
combine these submixes to build a final mix. Soundtrack Pro is designed with this workflow
in mind.

306

Chapter 12 Basic Mixing in Soundtrack Pro

What Is a Submix and How Do You Use It?
In Soundtrack Pro, you use a submix to combine (or “sum”) the audio from different tracks
and busses, and route the audio to physical outputs. The name of this feature implies its
purpose—to mix the audio signals of a subset of the tracks and busses in your project.
If you are using external audio hardware that supports multiple physical outputs, you
can have multiple submixes in your project and then choose the physical output to which
each submix routes its audio. By default, all tracks are routed to Submix 1, and Submix 1
is routed to the Stereo 1, 2 outputs. You can easily add more submixes, reroute audio,
and change the hardware output setting using the Output pop-up menu in each submix.

Basic Signal Routing in Soundtrack Pro
At a minimum, any audio that you edit in the Soundtrack Pro Timeline passes through
the following “mixer objects” on its way out to the physical audio outputs: a track, a
submix, and the Master bus.

Audio post-production projects typically include many tracks and submixes. The following
diagram shows the signal flow of multiple tracks to just one submix. While this is an
unlikely scenario, it illustrates the fact that you can route as many tracks to a submix as
you like. See Example: Mixing a Project with Submixes for a typical example.

Setting the Submixes for Tracks and Busses
To be included in a project, the audio signal of each track and each bus must be routed
to a submix. By default, in new multitrack projects, there is only one submix (Submix 1)
and all tracks are routed to Submix 1. You can add as many submixes as you like and
route as many signals from tracks and busses to those submixes as you want.
To create a more elaborate project (as described in Example: Mixing a Project with
Submixes), you create additional submixes.

Chapter 12 Basic Mixing in Soundtrack Pro

307

To add a submix
Do one of the following:

µ
µ

Choose Multitrack > Add Submix.
Control-click a submix, then choose either Insert Submix Before or Insert Submix After
from the shortcut menu.
Once you have created multiple submixes, you can route any combination of tracks or
busses to any submix.

To set the submix for a track or bus
Choose the submix from the Submix pop-up menu in the track header or at the bottom
of the Mixer channel strip for the track or bus.

If you choose None from the pop-up menu, you are effectively removing that track or
bus from the mix and from the final output.
Setting Hardware Outputs
Use the Output pop-up menu in each submix to choose an output channel or set of
output channels. Your choice defines the output of that submix as either mono, stereo,
or surround.

To select the hardware output jacks for a submix
Click None, Surround, Stereo, or Mono from the Output pop-up menu in the track header
of each submix, then choose a channel or set of channels from the submenu.

The available choices within each of these output categories depend on the number of
available physical outputs and number of submixes in your project.
If you choose None from the Output pop-up menu, you are effectively removing that
submix from the mix and from the final output.

308

Chapter 12 Basic Mixing in Soundtrack Pro

Note: You can create submixes independently of the audio hardware connected to your
computer and can route audio to an output that does not correspond to a physical output.
In most situations, each submix in a project should correspond to a physical output on
the audio interface or other hardware connected to your computer. Submixes that do
not correspond to a physical output will not be heard. You may set as many submixes in
a project to the same physical output device or output channel as you like.
For more information about system output settings, see Setting the Audio Input and
Output. For more information about connecting an audio interface, see Setting the Audio
Input and Output.
For more information about working with tracks, busses, and submixes in the Timeline,
see Tracks, Busses, Submixes, and the Master Bus and Working with Tracks, Busses, and
Submixes in the Timeline.

Example: Mixing a Project with Submixes
A classic audio post-production practice for film and video is creating separate submixes
for the dialogue, the music, and the sound effects. This provides an appropriate degree
of flexibility, both in the mixing phase and in distributing the final product.
Creating Submixes
In this example project, all tracks containing dialogue are routed to a submix called
“Dialogue.” The tracks containing sound effects are routed to a submix called “FX.” The
tracks containing music are routed to a submix called “Music.”

Dialogue tracks

Effects tracks

into their respective submixes.

Stage Mic
FX: Foley

Effects

Music: Music 1

Audio clip

Stereo panner

Once the audio signals are organized in this way, you can apply (and automate) volume
settings and effects on any of the submixes, rather than on the individual tracks or busses.
You might, for example, add a compressor or EQ effect to a Dialogue submix to enhance
all of the dialogue signals at once. Obviously, this saves a lot of time and effort (when
compared with applying all of these settings to each dialogue track individually). Using
submixes to segment your project provides you with greater control over all aspects of
your final mix.
Creating a Stereo Mix
The next routing decision is the choice of hardware outputs. The following example
diagram shows the routing for a traditional final product: a stereo mix. To do this, you
would simply choose the Stereo 1,2 output for each of the three submixes. (This also
happens to be the default output for every submix in Soundtrack Pro.)

In this case, the left and right channels for each submix are routed to the left and right
(1 and 2) channels of the hardware output device. All three submixes are combined into
one stereo (left and right) signal. This is a “stereo mixdown,” suitable for any stereo-capable
playback device. At this stage, the Master bus presents a (final) opportunity to make
volume adjustments and apply effects. For information about the Master bus, see Using
the Master Bus.
Creating a Separate Music and Effects Mix
Using submixes in your workflow becomes very powerful when you consider the many
different ways you might be delivering the final program. One common practice is creating
a separate music and effects (M & E) submix for foreign distribution. This gives distributors
the option to create versions of the program with the dialogue dubbed in foreign
languages but to still include the program’s original music and effects in the dubbed
versions.

As in the stereo mixdown example, the Dialogue submix is routed to the Stereo 1,2 output.
But the Music and Effects submixes are routed to the Stereo 3,4 output channels, isolating
the dialogue signal from the music and effects signals. Technically, only one output
channel is required for the dialogue, because the Dialogue submix is made up of mono
signals. But in practice, it is usually routed as two identical mono signals to channels 1
and 2. Most likely, producers making the foreign language version will use the original
dialogue as a guide track and then replace it with their edited foreign language track in
the final mix.
This M & E case is just one simple example of how you can structure a project for an
efficient workflow. Each mix project comes with its own particular quirks. The good news
is that Soundtrack Pro has a lot of flexibility. For example, the sends and busses features
in Soundtrack Pro offer additional options for structuring a project. For more information,
see Working with Sends and Busses in the Mixer.

Chapter 12 Basic Mixing in Soundtrack Pro

Signal Routing for a Separate Music and Effects Mix in Surround
When you shift from a stereo project to surround, you need to keep in mind some minor
signal routing consequences. This section discusses what changes you would make to
the submix and output settings. (For information about creating a surround version of a
stereo project, see Converting a Stereo Mix to 5.1 Surround.) First, assuming that the
music and effects are mixed over six surround channels, those submixes must be routed
to the Surround 1-6 output. The Dialogue submix could either remain routed to the Stereo
1,2 output jacks to be added to the Surround 1-6 mix or routed to the center channel at
the submix, or could be panned to the center channel in a surround signal, as shown
below.

Using Sends and Busses
You can use sends to split an audio signal into two or more separate signals. A send taps
a track’s audio signal and routes it down a separate but parallel path. In Soundtrack Pro,
these separate paths are known as busses. (Some might call these auxiliary busses.) This
process is analogous to diverting a portion of a river to an alternate (but parallel) stream.
Busses are like alternate streams of audio. They can be processed or combined
independently of the “main river.” They can rejoin the main signal further “downstream,”
at the final mix, or they can be routed to altogether separate outputs.

By preparing these alternate versions and combinations of track audio signals, you give
yourself more options at the final mix stage, when all of your project’s media elements
and adjustments are in place.
For an example of adding effects with sends and busses, see Example: Adding Effects
with Sends and Busses.
For an example of combining track signals with busses, see Example: Combining Track
Signals with Sends and Busses.

Example: Adding Effects with Sends and Busses
The following example shows how you could add a reverb effect to a music track using
a bus. The main reason to apply effects this way (rather than directly on the track) is so
you can control the amount and characteristics of the effect (in this case, reverb) on
multiple tracks using one set of controls.
For more information on using sends and busses, see Using Sends and Busses.
To add a reverb effect to a music track using a bus
1 Create a new bus. (In this example, the new bus is named “MusicReverb.”)
2 Add a send to the music track.
For specific information about how to add sends to tracks and route them to busses, see
Adding Sends to Tracks.
3 Route the new send to the MusicReverb bus.

As the diagram shows, the new MusicReverb bus represents an alternate version of the
Music track audio signal. Once created, this bus appears as a row in the Timeline and a
channel strip in the Mixer. It becomes a resource to draw from during the final mix. Rather
than having to tweak the effects settings of individual tracks in the mix, you can simply
adjust the volume fader on the MusicReverb bus to increase or decrease the amount of
reverb on that music track.
By default, new sends are post-fader sends. This means the signal is tapped after the
track’s output fader. In this example, adjusting the Volume slider on the Music track would
have a direct effect on the music level in the MusicReverb bus.

In contrast, a pre-fader send taps the track signal before a track’s output fader. You can

In the pre-fader case, adjusting the Volume slider on the Music track would have no effect

Example: Combining Track Signals with Sends and Busses
You can also send the signals from multiple tracks to a single bus, creating “intermediate
submixes.” For example, you could route every dialogue track for a particular actor to a
bus with the actor’s name. You could adjust the volume of all the actor’s dialogue using
the bus volume fader and add an EQ effect that brings out the actor’s voice in the mix.
You could then send (route) the bus to a particular submix.

In the above diagram, tracks 1 and 4 contain dialogue from the actor, Jacob. Each of these

This bus is effectively an intermediate submix. Now, any effects and fader adjustments
applied to this bus will be available during the final mix as a single channel strip (named
“Jacob”).
For more information about using sends and busses in the Mixer, see Working with Sends
and Busses in the Mixer.

Using the Mixer
While most mixing tasks can be accomplished in the Timeline and elsewhere in the
Soundtrack Pro interface, the Mixer offers an interface analogous to hardware mixing
consoles found in most audio post-production facilities. Another advantage of the Mixer
is that you can view levels on all (or at least many) tracks simultaneously in real time.

The Mixer features a series of vertically arranged controls called channel strips, like the
channel strips in a hardware mixing console. The channel strips in the Mixer correspond
to the horizontal tracks, busses, and submixes in the project Timeline.

Channel strip

The controls a channel strip contains depend on whether it is a track, bus, or submix
channel strip. The controls for each type are as follows:

Name

The channel strips in the Mixer make it easy to see the settings for all the tracks, busses,
and submixes in your project at once and to adjust those settings relative to each other
as you create the overall mix.
In the Mixer, the channel strips appear in order corresponding to their order in the
Timeline. Top-to-bottom order in the Timeline corresponds to left-to-right order in the
Mixer. You can reorder tracks in the Mixer and have the new order reflected in the Timeline.
Changes you make to controls such as volume and pan also show up in the track controls
when you open the project in the Timeline.

Using Custom Layouts for Mixing
You can rearrange the Soundtrack Pro layout to suit your particular mixing workflow.
There are numerous possible combinations. You can tear off tabs and have them float
over the Soundtrack Pro window or show them on a second display. One default layout
(in addition to the standard layout) floats the Mixer and the Video tabs as separate
windows. This allows you to further resize the Mixer and the Video windows to an
arrangement that is convenient for mixing.
To display the Mixer and Video tabs as separate windows
Do one of the following:

µ
µ

Choose Window > Layouts > Separate Mixer and Video (or press F2).
Using the pointer, drag the Mixer and Video tabs out of their docked positions.
The Mixer and the Video tabs float over the Soundtrack Pro window as separate windows.

Shift-click the channel strips you want to select.

Chapter 12 Basic Mixing in Soundtrack Pro

To select nonadjacent channel strips
Command-click the channel strips you want to select.

Reordering Channel Strips
You can change the order of channel strips in the Mixer. When you open the Mixer, the
order of channel strips corresponds to the order of tracks, busses, and submixes in the
Timeline. Because channel strips are oriented horizontally in the Mixer, top-to-bottom
order in the Timeline corresponds to left-to-right order in the Mixer. Reordering channel
strips in the Mixer also changes their order in the Timeline.
In the Mixer, as in the Timeline, channel strips of the same type (track, bus, or submix)
are grouped together. You can reorder a channel strip within its own group, but cannot
move it to a group of a different type. You can only move one channel strip at a time.

To reorder a channel strip
Drag the channel strip left or right to a new position.

Copying Channel Strips
You can copy channel strips in the Mixer. You can copy a channel strip within its own
group, but cannot copy it to a group of a different type. You can only copy one channel
strip at a time.

To copy a channel strip
Option-click the channel strip, then drag it left or right.
A copy of the channel strip appears when you release the mouse button.

Setting Channel Strip Volume Levels
You set relative volume levels to balance the various parts of the project. You set the
volume level of a channel strip using the channel strip volume fader or value slider.
Different sounds can have different apparent loudness at the same volume level, so
perceived loudness does not precisely correspond to numeric values on the volume
faders. You determine the appropriate volume level by listening to the track and adjusting
its level in the overall mix.
To set the volume level of a channel strip
Do one of the following:

Drag the volume fader up to raise (increase) the volume, or drag it down to lower
(decrease) the volume.

Setting Channel Strip Output
On a hardware mixing console, you can send signals to different busses and physical
outputs. You can create submixes and busses in Soundtrack Pro, assign tracks and busses
to different submixes, and assign submixes to physical output channels on connected
audio devices. You can send audio from as many tracks and busses to the same output
as you want.

To set the submix for a track or bus
Choose the submix from the Submix pop-up menu at the bottom of the channel strip
for the track or bus.

Submix pop-up menu

For submixes in the Mixer, the Output pop-up menu lists the available output channels.

321

To set the output for a submix in the Mixer
In the channel strip for the submix, choose the output channel or set of channels from
the Output pop-up menu.

The options listed in the Output pop-up menu depend on the number of available physical
outputs and the number of submixes in your project. For more information about setting
the output, see Setting Hardware Outputs.
Note: You can create submixes independently of the audio hardware connected to your
computer and can route audio to an output that does not correspond to a physical output.
In most situations, each submix in a project should correspond to a physical output on
the audio interface or other hardware connected to your computer. Submixes that do
not correspond to a physical output will not be heard. You may set as many submixes in
a project to the same physical output device or output channel as you like.

To select an audio interface as the output device
Choose Apple menu > System Preferences, click Sound, then click the Output button.
Select the audio interface in the list that appears.

Using the Channel Strip Level Meters
Each channel strip includes level meters to the left of its volume fader. You can use the
level meters to observe each channel strip’s level as the project plays. The level meters
range from -96 dB to +6 dB, moving from bottom to top as the level increases. The
segments of the level meters run from green through yellow to orange as the level
increases.
Note: For surround signals, the channel strip meters show the signals in this order: Ls, L,
C, R, Rs, LFE. This matches the surround order in the Meters tab. (See Setting the Overall
Project Volume Level for more information.)
At the top of each set of level meters is a peak indicator. As the project plays, the value
in decibels of the highest level reached appears in the peak indicator. If the level rises
above 0 dB, the peak indicator becomes red. The values shown in each peak indicator
remain until you play the project again, close the project, or reset the peak indicator.

Working with Sends and Busses in the Mixer
This section covers using sends in Mixer channel strips. For more general information
about sends and busses, see Using Sends and Busses and Adding Sends to Tracks.
Adding Sends to a Channel Strip
You can add sends to a channel strip, show send settings in the Effects tab, bypass a send,
or remove a send in the Mixer.

To add a send to a channel strip
Control-click an empty effects slot in the channel strip, choose Add Send from the shortcut
menu, then choose one of the available busses in the submenu.
The new send is added. When you add a send, the audio is routed from the send to a
bus. By default, the first send you add to an effects chain is routed to Bus 1, the second
send is routed to Bus 2, and so on, if the default bus exists. You can choose the bus to
which a send is routed.
By default, new sends are post-fader sends. You can change a send to a pre-fader send.

To make a send a pre-fader send
Click the disclosure triangle for the send in the Effects tab, then select the On button next
to Pre-Fader.
Reordering Sends in the Mixer

Setting the Overall Project Volume Level
As you finalize a project mix, you set the overall project volume to the appropriate level.
Certain formats or methods of distribution may require that the project conform to a
particular maximum level. In general, you set the overall volume of the project to the
highest level at which no clipping occurs at any point in the project.
Clipping occurs when the digital audio signal exceeds the maximum level that can be
reproduced accurately. Unlike analog audio, digital audio is completely unforgiving of
clipping, which creates sharp distortion of the audio signal. Soundtrack Pro projects clip
whenever the output displayed in the level meters exceeds zero decibels (0 dB). It’s
important to eliminate clipping from projects before exporting the final mix. For more
information about digital distortion, see Audio Fundamentals.
You can monitor audio output levels using the level meters in the Mixer, the Meters tab,
and in individual track headers. In the Mixer, each channel strip has level meters that
show the levels for that channel strip. In the Meters tab, the level meters show the levels
for all submixes assigned to physical output channels. For more information about setting
up physical outputs, see Setting the Audio Input and Output.
The Meters tab includes additional controls and displays to help you maintain proper
audio levels and eliminate clipping.

Chapter 12 Basic Mixing in Soundtrack Pro

As a project plays back, the levels in each channel change constantly with the rising and
falling of the audio signal. The level meters show these changes both as bars rising to
varying heights and as changes in color from green to yellow.
In each channel’s meter, a white horizontal bar displays the current signal level; bars
below the white bar display successive levels in a scale that rises from green to yellow
as the signal increases. The meters peak at red when the signal clips (rises above 0 dB).
Note: The meters can be configured via Soundtrack Pro preferences to display either
surround order (Ls, L, C, R, Rs, LFE) or output order (channels 1-n). To change this setting,
choose Soundtrack Pro > Preferences > General.
To change the channel order in the meter display
1 Choose Soundtrack Pro > Preferences.
2 Select the General pane.
3 In the Timeline section, select your preferred channel display order from the Meters
Channel Display pop-up menu.
For more information about Soundtrack Pro preferences, see Soundtrack Pro Preferences.
Using the Peak Indicators in the Mixer Channel Strips
At the top of the level meters in the Mixer channel strips is a rectangular peak indicator
that lights red when that channel clips (exceeds 0 dB). The peak indicators are “sticky,”
meaning that if clipping occurs in either channel, the peak indicator lights red and stays
red until you reset it, or reset all peak indicators.

To reset a peak indicator
Click the peak indicator.

To reset all peak indicators
Option-click any peak indicator in any of the Mixer level meters.
Using the Peaks Value and Location Display in the Meters Tab
The Peaks Value and Location display in the Meters tab displays the highest (peak) value
played in each output channel in decibels (dB) and its timecode. The Time column shows
the location in the Timeline where the peak occurs. You can use the Peaks Value and
Location display to quickly locate a section of your project that is clipping or peaking.

To move the playhead to the highest (peak) value played in a channel
Double-click any item in the Peaks Value and Location display.
The playhead moves to the corresponding point in the Timeline.
The Reset button located in the upper-right corner of the Meters tab display resets the
Peaks Value and Location display to a minimum value (-96 dB) and resets the Time column
to the beginning of the project.

Chapter 12 Basic Mixing in Soundtrack Pro

331

To reset the Peaks Value and Location display values
Click the Reset button.

Using the Master Bus
The Master bus represents the final mix from Soundtrack Pro—what will be heard from
the physical output jacks. On a signal routing basis, the Master bus is practically a mirror
image of the connected hardware output device. It is as wide as either the hardware
device or the number of channels used in the project, whichever number is smaller.
Master Bus Details
The Master bus includes envelopes for volume, transposition, and tempo. By default, only
the Volume envelope is visible. For more information, see Master Bus. The Master bus
does not have panners or meters.
You can apply effects to the Master bus, but you cannot automate those effects. Effects
applied to the Master bus are placed across all channels. You can bypass effects on the
Master bus. For more information about bypassing effects, see Bypassing Realtime Effects.
Adjusting the Master Volume
The steps you take to remove clipping depend on the cause of the clipping. You can
lower the master volume of a project by the amount the highest point in the project (as
shown in the Value display) exceeds 0 dB. You can also use the Go buttons to locate
where clipping occurs and use a different audio clip or lower the volume of individual
tracks until clipping no longer occurs. Sometimes adjusting the gain on effects can remove
occurrences of clipping as well.

Listening to a Temporary Mono Mix
In some situations, even where the final mix is stereo, you may want to listen to the mix
in mono as well as stereo. If the final project is likely to be viewed using equipment with
mono audio output (for example, many television sets have mono output), you may want
to make sure the mix is suitable for mono output. Listening to a mono mix can also help
identify phase issues that can occur when a stereo project is played in mono.
Soundtrack Pro makes it easy to listen to a temporary mono mix of the project so you
can hear how it will sound in mono.
To listen to a temporary mono mix
1 Start the project playing.
2 While the project plays, press and hold the Mono Mix button, located to the right of the
Monitor volume slider below the Mixer.

Mono Mix button

332

Chapter 12 Basic Mixing in Soundtrack Pro

The Mono Mix button becomes darker to indicate that it is active. When you are finished
listening to the temporary mono mix, release the button to hear the project mix.
In addition to listening to a temporary mono mix by holding down the Mono Mix button,
you can “latch” the Mono Mix button. This keeps the mono mix active until you click the
button again or switch to a different project.

To latch the Mono Mix button
Option-click the Mono Mix button.

Recording Audio in the Mixer
You can record audio while working in the Mixer. When you record audio in the Mixer,
recording starts from the current playhead position. Although the playhead is not visible
in the Mixer, you can set the playhead position using the transport controls or the Playhead
Location value slider located at the bottom of the Soundtrack Pro window.
For more information about recording, see Recording Audio in Soundtrack Pro.

Recording Automation in the Mixer
You can record automation for volume and pan changes in the Mixer. You record
automation in the Mixer by choosing either Touch or Latch automation mode in the
project controls, then changing volume or pan settings as the project plays. You can
record automation either using the onscreen volume and pan controls, or using a control
surface connected to your computer.
For more information about working with automation, see Working with Automation.

Creating Multiple Mixes
You might want to create multiple mixes of a project for one of the following reasons:
• To optimize the project for different playback situations
• To try out different settings of the various track and master controls using the same
arrangement
• To try out changes to the arrangement using the same basic material
You can easily create multiple mixes by giving the project a slightly different name when
you save each mix, or by using different combinations of tracks, busses, and submixes
for each mix. If you are saving the project and its media files together, the different
versions can be saved to the same location if they all use the same media files. For
information about saving projects and their media files together, see Saving Multitrack
Projects.

Things to Keep in Mind While Mixing
The following are intended as guidelines or suggestions to follow when mixing your
projects, not as “hard-and-fast” instructions.
• Consider the importance of each element in the overall mix.
• Keep related tracks close together (in the Timeline and the Mixer).
• Don’t create a final mix until the picture is locked.
• Listen to the mix with the best possible equipment.
• Also listen to the mix as the audience will hear it.
• Don’t change output/monitor levels while mixing.
• Mix by what you hear, not by what you see.

Chapter 12 Basic Mixing in Soundtrack Pro

Mixing Surround Sound

Soundtrack Pro gives you the tools to create sophisticated surround mixes for your projects.
Surround sound uses more than two speakers to expand the spatial experience of audio
playback to three dimensions. Surround systems can be found in movie theaters, home
entertainment systems, video games, and a growing number of other applications.
Soundtrack Pro offers an easy-to-use approach to surround panning, mixing, and
automation, including a high degree of flexibility with surround sources and the ability
to easily switch between stereo and surround mixes. Soundtrack Pro also includes
numerous surround sound effects and surround music beds, as well as a collection of
professional surround-specific effect plug-ins for shaping your surround mix.
This chapter covers the following:
• What Is 5.1 Surround? (p. 335)
• Creating a Surround Project (p. 336)
• Setting Up Soundtrack Pro for Surround (p. 336)
• Using Surround Panners to Create a Surround Mix (p. 341)
• Surround Mixing Strategies (p. 347)
• Exporting and Delivering 5.1 Surround Projects (p. 353)

What Is 5.1 Surround?
The most common surround format is a six-channel system called 5.1 surround. This format
is the standard surround configuration in major motion pictures, music, and digital
television. The format consists of three speakers across the front and two speakers in the
rear. The .1 is a sixth channel for low-frequency effects (LFE). A typical 5.1 surround layout
features left and right speakers (from a traditional stereo system) plus a center speaker,
a left surround (rear) speaker, a right surround (rear) speaker, and an LFE speaker, more
commonly known as the subwoofer.
There are other surround standards that range from three channels to seven channels
and nonstandard surround formats that use as many as ten channels.

335

Creating a Surround Project
The following steps outline a general workflow used for editing and mixing surround
sound files.
Stage 1: Acquiring the Sound
As with any audio track, the first step is finding and recording the sound that you want.
Soundtrack Pro is flexible in terms of what kinds of files you can use in the surround mix.
Input files can be mono, stereo, or surround. While Soundtrack Pro also includes numerous
surround clips for music and sound effects, the production audio for most film and video
projects is typically either mono or stereo files.
Stage 2: Editing and Arranging a Multitrack Project
The workflow for editing audio files and arranging them in the multitrack Timeline is very
similar for stereo and surround projects. For more information, see Working with Multitrack
Projects, Working in the Timeline, and Working in the File Editor.
Stage 3: Mixing Surround
Soundtrack Pro provides a flexible toolset for creating and adjusting a surround mix. For
more information, see Surround Mixing Strategies.
Stage 4: Exporting and Delivering Surround Projects
Soundtrack Pro supports a variety of workflows and formats for delivering your final
surround mix. These include separate audio files for each channel or single multichannel
sound files for the entire mix.

Setting Up Soundtrack Pro for Surround
In order to hear your surround project through a surround speaker system, you need to
adjust settings in Soundtrack Pro and set up the related hardware.
In Soundtrack Pro, the difference between mixing in stereo and mixing in surround hinges
on three different elements: the panner type, the submix output, and the number of
physical output channels. All three of these items must be configured correctly to achieve
surround playback. If one of these three conditions is not met, playback will be in stereo.
(For more information about stereo mixdown, see Stereo Mixdown.) Use the instructions
that follow to start using the surround mixing tools in Soundtrack Pro.

The surround panner replaces the stereo panner.

As far as tracks and busses are concerned, switching between surround mode and stereo
mode is that simple. At this point, you are mixing this particular track or bus in surround.
Any surround panning adjustments and automation that you apply are saved with the
current project.
Important: To hear these changes through your speakers, make sure you also set the
submix outputs to surround and connect the physical outputs. For more information, see
Setting the Submix Outputs to Surround and Connecting Physical Outputs.

Setting the Submix Outputs to Surround
In Soundtrack Pro, you route the audio from tracks and busses to physical outputs using
submixes. By default, all tracks are routed to Submix 1, and Submix 1 is routed to the
Stereo 1, 2 outputs. You can easily change this hardware output setting using the Output
pop-up menu.

To switch the hardware output setting from stereo to surround
Choose Surround from the Output pop-up menu in the track header, then choose 1-6
from the submenu.

The menu displays 1-6, indicating that the audio is now routed to the physical output
jacks 1 through 6. At this point, the signal is routed to those six outputs, whether or not
the hardware to support those channels is connected.
Important: To hear these surround signals through loudspeakers, you must also connect
the physical outputs. For more information, see Connecting Physical Outputs.

Connecting Physical Outputs
To hear the six discrete channels of surround sound that Soundtrack Pro can provide, you
need external audio hardware that supports multiple physical outputs. At a minimum,
this would include a multichannel audio interface and a 5.1-channel surround sound
speaker system (totaling six speakers). For more information about audio interfaces, see
Setting Up an Audio Interface.

Chapter 13 Mixing Surround Sound

To connect physical outputs for monitoring surround sound
1 Connect the audio interface to your computer.
For detailed information on connecting your audio interface to your computer, see the
documentation that came with the audio interface.
2 Double-click Audio MIDI Setup in the Utilities folder, then choose the audio interface from
the Default Output pop-up menu.
For more information, see Setting the Audio Input and Output.
3 Connect your 5.1-channel surround sound speakers to the appropriate outputs of your
audio interface.
Soundtrack Pro uses the SMPTE/ITU standard for routing output channels.

Stereo Mixdown
If you have set up a project for surround mixing, including surround panners and surround
channel assignments, but you do not have sufficient output jacks for surround playback,
Soundtrack Pro automatically provides a surround-to-stereo mixdown of what would
otherwise be sent to jacks 1-6. This stereo mixdown follows the Dolby guidelines: the Ls
and Rs channels are attenuated by 3 dB and mixed into the Left and Right channels. The
Center channel is also attenuated by 3 dB and mixed evenly into the Left and Right
channels. The LFE channel is discarded.

Surround Speaker Placement
There are several ways you can arrange 5.1 surround speakers for playback. You can follow
the International Telecommunications Union Operational Bulletin No. 775 or the “ITU
Standard” for 5.1 surround sound. Here are the basic points of this recommendation:
• Place all the speakers on the same plane. In other words, if you place some speakers
on the floor and mount some on the ceiling, you will defeat the psychoacoustical
benefit of having surround speakers in the first place.

Chapter 13 Mixing Surround Sound

339

• With the center speaker directly in front, the Left and Right speakers should be
positioned 30 degrees away from center at about a 60-degree angle aiming for a spot
3 to 6 inches behind the mixer’s (or listener’s) head.
Note: This angle can be reduced to 45 degrees or extended out to 60 or even 90 degrees
and still provide satisfactory results.
• Place the surround (rear) speakers at about 110 degrees off center (to the sides and
somewhat behind the listener). To ensure one cohesive soundfield, do not position
these speakers too far to the rear.

Chapter 13 Mixing Surround Sound

Using Surround Panners to Create a Surround Mix
The following sections explain how to use the surround panners in Soundtrack Pro to
create a surround mix. The surround panners provide a straightforward and flexible way
to control and monitor panning settings. By changing the panner type in the track header,
you can easily switch any track or bus from stereo to surround, or from surround to stereo.
Soundtrack Pro offers two different versions of the surround panner: the mini surround
panner and the surround panner HUD.

The Mini Surround Panner
Use the mini surround panner to switch between stereo and surround mixing, to make
simple surround adjustments, and to quickly check the pan setting for a track or a bus.
To switch the panning controls from stereo to surround
Do one of the following:

µ
µ

Select the track or bus, then choose Multitrack > Use Surround Panner.
Control-click the stereo pan slider in the track header, then choose Use Surround Panner
from the shortcut menu.

The surround panner replaces the stereo panner. This is the smaller of two different views
of the surround panner. To use the larger Surround Panner HUD, see The Surround Panner
HUD.

The Surround Panner HUD
The Surround Panner HUD offers finer panning adjustments, a graphic representation of
the current surround setting for the selected track, and other surround controls.
To display the surround panner HUD
Do one of the following:

Double-click the surround panner in the track header of the track or bus you want to
adjust.

Double-click the surround panner in the Mixer channel strip of the track or bus you want
to adjust.

Chapter 13 Mixing Surround Sound

341

The surround panner HUD appears in a floating window over the Soundtrack Pro window.
The dominant feature of the Surround Panner HUD is the black circle that represents the
virtual surround space. The puck, a dot inside the circle, is the primary surround pan
control. Input channels are represented by color-coded, semi-circular, translucent arcs
emanating from the inside of the circle’s circumference. These arcs indicate the input
channel’s gain (by the height of the arc), the channel’s spread (by the width of the arc),
and location. Overlapping sounds are represented by overlapping arcs, summing
(combining) to white where all channels overlap.

Puck (pan position)

Rotation slider
Width slider
Collapse slider
Center bias slider
LFE balance slider

• Position: The puck is the main control in the panner. To pan the audio, move the puck
by clicking anywhere inside the black circle or by dragging the puck to a different
position in the circle. The speaker icons around the edge of the circle represent the
five main surround channels: L (left), C (center), R (right), Ls (left surround), and Rs (right
surround). The closer you move the puck to one of the speaker icons, the louder the
sound will be from that speaker. For more information about moving the puck to adjust
the position parameter, see Modifier Keys for Moving the Puck.
Note: In automation envelopes, this Position parameter is expressed as Surround Pan
X and Surround Pan Y.

342

Chapter 13 Mixing Surround Sound

• Rotation: Use this slider to alter the angle at which each signal starts out. This slider
ranges from -180 degrees to 180 degrees and affects the input signal. For example,
with no other panning, the right channel emanates from a location 45 degrees to the
right. With rotation at +65 degrees, the signal appears at 110 degrees—directly out of
the right surround speaker.

To alter the angle from
which each signal starts...
...drag the Rotation slider.

Note: This setting interacts with the position parameter when the panner mode is not
fully attenuating.
• Width: Use the Width slider to create a widened surround image. This slider is intended
primarily for stereo sources in that it spreads the left and right inputs into adjacent
channels. This creates the illusion of a widened sound stage without the hole at the
center that moving the puck rearward would create. For some movie theaters, it may
be necessary to use the Width slider to bleed the center signal in to the left and right
speakers. At 0%, all inputs go to their respective outputs. As you drag the Width slider
to the right, L and R inputs start to bleed into Ls and Rs respectively, and to a lesser
extent, L and R bleed into C, C bleeds slightly into L and R, and Ls and Rs start to merge.

Chapter 13 Mixing Surround Sound

343

• Collapse: Typically, panners are either of a collapsing style (panning folds input signals
into output speakers) or an attenuating style (panning simply turns down the gain of
speakers further from the pan location). The Collapse slider goes from a fully attenuating
style, through a hybrid style, to a fully collapsing style. At full attenuate (0% on the
slider), no input bleeds to any other output; each channel remains at its original speaker
position. The only change is to output gain. At full collapse (100% on the slider), no
input gain is changed—instead, inputs have their output divided over adjacent channels.
At 50%, a given input channel panned away has its input attenuated by 50% and
distributed between the two adjacent channels.

Collapse at 0

Collapse at 50

Collapse at 95

• Center Bias: Use this slider to determine how the center channel interacts with the left
and right channels. At 0%, all sound that would have gone to the center speaker is
equally distributed to the left and right speaker. At 100%, the center is used fully, just
like any other speaker. This means that if you move the puck directly in front of the
center speaker, all sound emanates exclusively from that speaker. If you move the puck
halfway between the center channel and an adjacent channel (yet still on the perimeter
of the black circle), the sound is equally and exclusively divided between those two
speakers.
• LFE Balance: Use this slider to balance control between LFE and the other five channels.
At -100, nothing is output from the LFE speaker, even if there was LFE input, and all
other channels pass through at unity gain. At its midpoint (0), all six channels pass
through at unity gain to their respective speakers, meaning that LFE input passes
directly to LFE output. At +100, all six signals get summed to the LFE speaker.

344

Chapter 13 Mixing Surround Sound

• Speaker Disable: Click a speaker icon once to turn it on or off. If you turn off a speaker,
its output goes to adjacent speakers. Each speaker supports a single-click on/off for
that speaker’s output.

Click a speaker to turn
it on or off. A dim gray
color indicates the
speaker is off.

Surround Panner Automation
Automating surround pan settings is very similar to automating stereo pan settings: a
track or bus set to use the surround panner has at least seven different panning envelopes,
and a stereo track or bus has only one pan envelope. Automation for the Position
parameter (the puck) is reflected in two envelopes: Surround Pan X and Surround Pan Y.
These are Cartesian X & Y values referring to the puck position within the black panning
circle. All other surround panning parameters are expressed with one envelope each,
except for Collapse and Speaker Disable, which cannot be automated. For more
information about automation, see Working with Automation.

Modifier Keys for Moving the Puck
Hold down any of the following keys as you move the puck to constrain its movement.
These modifier keys offer finer control as you make adjustments to the position parameter.
• Shift: Fine adjustment
• Option-click: Reset control
• Option-drag: Straight movement, restricted to diversity, constant angle
• Command: Circular movement, restricted to angle, constant diversity
• Command-Option-drag: Restricted to either X or Y movement

Surround Metering
Soundtrack Pro provides a variety of level meters to monitor output levels as you make
surround panning adjustments.

Chapter 13 Mixing Surround Sound

345

Surround Panner HUD Meters
The Surround Panner HUD includes level meters that show volume information from the
specific track or bus that you are panning. These meters can be hidden or displayed by
using the disclosure triangle. Track-specific meters are a useful reference given the possible
psychoacoustical “illusions” in surround mixing, such as the phantom center.

Meters Tab
The Meters tab displays levels for the current multitrack project. The channels displayed
in the Meters tab and in the Mixer meters (described in Mixer Meters) depend on the
audio interface connected to your computer, the current panner settings, and the current
output settings in System Preferences.
For more information about output settings, see Connecting Physical Outputs.

Surround Mixing Strategies
This section includes guidelines and tips for mixing surround projects.

Mixing Surround Files
The basic steps in mixing are almost the same for stereo and surround projects:
• Balancing relative volume levels between tracks
• Panning tracks to create a balanced stereo spread
• Adding EQ, compression, and other final processing effects
• Setting the project’s final volume and eliminating clipping
• Creating a sense of perspective by placing sounds in space
While the creating a sense of perspective step is also a part of stereo mixing, it is what
really sets surround apart from stereo. When mixing, you can enhance the video action
by dynamically moving the sounds within the surround field. To give your listeners a
“surrounding” audio experience, your sound must be created with that goal in mind. For
example, if you want the sound of an explosion coming from behind the listener, you
need to put the sound in the rear channels during mixing. Surround mixing adds not
only two rear channels, but also includes the subwoofer or LFE channel, which would
probably play a part in any onscreen explosion. You’ll have to spend some time planning
what elements go where and how much boom you want in your soundtrack.

Chapter 13 Mixing Surround Sound

347

The following are some common approaches to multichannel sound:
• Use the surround channels for effects only. Create a stereo mix, then add “sweetening”
sound effects in the surround channels. Sound effects and Foley recordings can be
placed in stereo space or specifically located where they occur onscreen or offscreen.
• Create special sounds for the rear and low-frequency channels (the rumble of an
earthquake, the pounding of drums, an airplane buzzing overhead, and so on) and add
them to a standard stereo mix. (To create sound for the LFE channel, you can extract
low frequencies from the rest of your sound using band-pass filters.)
• Position instruments, effects, and voices anywhere in the sound field.

Converting a Stereo Mix to 5.1 Surround
Many post-production projects require both a stereo mix and a surround mix. This section
reviews some best practices for converting projects from stereo to surround. You can
reverse the steps below to convert a project from surround to stereo.
Important: When you switch between stereo and surround panners, panning automation
(envelope) settings are not automatically copied over to the new panning mode. Volume
information is automatically copied over between stereo and surround panners. The
recommended workflow for making a surround version of a stereo mix is to maintain at
least two separate versions of the project: a stereo version and a surround version.
To create a separate copy of your stereo mix for surround mixing
1 Choose File > Save As in your stereo project to save a separate copy.
In the dialog that appears, indicate in the filename that this is the surround version; for
example, “My Great Mix_surround.”

2 Use this copy of the project to make all the necessary surround panning adjustments.

348

Chapter 13 Mixing Surround Sound

In particular, you Control-click the stereo panner in the track header (or Mixer channel
strip) of each appropriate track or bus and choose Use Surround Panner from the shortcut
menu.

Set all panners to
surround panners.

Note: To save time, you can select or group all tracks or busses in the Tracks tab. When
you change the panning settings of one of the tracks or busses, the panning settings on
all the grouped items change as well.
3 If you previously applied any left-right panning to any tracks or busses in the stereo
version of the project, do the following:
a Select the tracks or busses.
b Control-click the panner in the track header, then choose Replace Surround L/R with
Stereo L/R from the shortcut menu.

Any panning automation (envelope) information is copied from the stereo left-right pan
to the surround left-right pan (specifically, to the Surround Pan X parameter) in the
selected tracks and busses. These settings can be used to provide a starting point for
your surround mix.
Note: If you are converting a surround project to a stereo project, you can choose Replace
Stereo L/R with Surround L/R from the shortcut menu to do the reverse of step 3.

Chapter 13 Mixing Surround Sound

349

Placing Dialogue and Voiceover in a Surround Mix
In a surround mix, dialogue usually goes directly into the center channel. This is particularly
true for voiceover narration, which is best left out of the left and right channels. (This is
called stereo plus center.) Soundtrack Pro allows you to place sounds exclusively in a
specific channel or just outside that channel, which would allow some of the sound to
leak into the other speakers. As you get more comfortable with surround mixing, you
may want to experiment with alternative placements to further reinforce the voices that
you place within your mix.
To place dialogue and narration in the center channel
1 If you haven’t already done so, Control-click the stereo pan slider in the track header of
the dialogue track (or bus), then choose Use Surround Panner from the shortcut menu.
2 Double-click the surround panner.
The Surround Panner HUD appears.
3 Drag the puck to the center speaker icon.
Note: You can hold down the Option key as you drag the puck to constrain its movement
to a straight line.
Depending on the current Collapse slider setting, the arc at the center speaker icon either
turns white to indicate exclusive output or is elongated to indicate the increased gain.

350

Chapter 13 Mixing Surround Sound

Placing Stereo Music in a Surround Mix
The simplest option for stereo music in a surround project is to just leave it in stereo. If
you just use the stereo panner for a music track, the left and right signals remain in their
respective channels. However, some surround mixes include a hint of music in the rear
channels as well. With the Surround Panner HUD, you can place the right music channel
somewhere between the right front and right rear position, with more emphasis on the
front speaker. Do the same with the left side and listen to the mix. Make adjustments as
needed.

Using the Center Channel
In a multichannel system, there are three ways to achieve a centrally placed sound image:
Create a “phantom center” (mix sound to the left and right equally, as with stereo)
This is a common strategy, but it assumes the listener is seated exactly between the
speakers. The timbre of sound is not the same as from a direct speaker because of
cross-cancelation effects.
Use the center channel alone
This creates a stable center image for listeners in any location. (To prevent the audio from
sounding too focused or narrow, its reverb can be spread to the left and right channels.)
Use all three front channels equally or in various proportions
This method allows for greater control of the range of spatial depth and width. The
phantom center can be reinforced by additional signals in the center channel, which can
be enhanced by signal spread into the left/right pair. The disadvantage is that sound
from all three speakers may not blend well or may not arrive at the listener at the same
time, causing side effects such as comb filtering, shifts in tone color, or smearing. To
counteract these side effects, you can first process the additional signals to change their
spatial character, timbre, or prominence relative to the main center signal.

Using Surround Channels
Subtle surround effects can greatly enhance the listener’s sense of depth compared to
conventional stereo. Popular music often benefits from creative use of surround. But
don’t overdo it. The film industry guideline for visual effects applies equally well to
surround effects—don’t let effects distract the listeners from the story.

Using Surround Effect Plug-ins
Soundtrack Pro includes a collection of professional surround-specific effect plug-ins for
shaping your surround mix, including Surround Compressor, Delay Designer, Space
Designer, and Multichannel Gain.
For a complete list of these true surround effects and a full description of each, see the
Soundtrack Pro Effects Reference document, available in the Help menu. For information
about using processing and realtime effect plug-ins, see Working with Audio Effects.

Chapter 13 Mixing Surround Sound

351

Limitations of the LFE Channel
Use the LFE (Low Frequency Effects) channel to enhance the low frequencies of a film or
video so you get the extra boom out of an explosion, thump in a car crash, and so on in
dramatic scenes involving plenty of low frequencies. The low frequency effects (LFE)
channel is a separate signal with a limited frequency range (about 25 Hz to 120 Hz). It is
created by the mixing engineer and delivered alongside the main channels in the mix.
In soundtracks comprised entirely of music, the LFE channel is not necessary. (An exception
to this rule might be the famous cannon shots in Tchaikovsky’s “1812 Overture.”) The LFE
signal is also discarded in the downmix process, so that intense bass signals do not stress
small stereo systems. Be sure not to include vital information (such as dialogue) in the
LFE channel that would be missed in mono or stereo playback.
Because LFE is separate from other channels, its ability to blend with higher frequencies
can be affected by filters used to generate the LFE signal. To ensure a cohesive audio
signal, keep the entire signal together in the main channel or channels.
Note: If you are creating Dolby Digital Professional (AC-3) output, avoid creating an LFE
channel for material originally produced without one. Dolby Digital Professional’s five
main channels are all full-range, and the LFE channel does not increase the frequency
response. Dolby Digital Professional decoders offer bass management, directing low
frequencies to a subwoofer or other suitable speakers. An LFE track may interfere with
bass management. For more information about Dolby Digital Professional, see the Dolby
Laboratories Inc. website at http://www.dolby.com.

Accommodating Stereo Playback
Even with the popularity of 5.1 systems, you should always address stereo reproduction.
There are three basic ways to do this:
• Prepare a new stereo mix from the original multitrack elements (using conventional
stereo-mixing sessions).
• Prepare a studio-adjusted downmix from the multichannel mix. This method takes
advantage of the work that has gone into mixing the 5.1 version. It retains flexibility in
the exact proportions of each channel represented in the final stereo mix.
• Let the decoder derive a stereo downmix, based on preset formulas in the decoder.
Downmix options and dynamic range control effects can be previewed and adjusted
in the production studio, and a range of adjustments is possible.
Tip: Always check the mix on an inexpensive surround system to evaluate how well it
sounds on modest playback systems.

352

Chapter 13 Mixing Surround Sound

Exporting and Delivering 5.1 Surround Projects
Delivery of your finished surround mix can take many forms. Different clients have different
file format requirements. In general terms, your options include two broad categories:
mixdowns and project files.

Mixdowns
In this scenario, you would export one of the following:
• Six audio files, one for each of the six surround output channels
• An interleaved multichannel audio file containing all six surround output channels
• A single flat mixdown file either as an exported file or one sent to Final Cut Pro or
Motion
Soundtrack Pro supports the following file formats for six-channel audio export (either
as a set of mono files, or as an interleaved multichannel file):
• AIFF
• WAVE
• NeXT
• Sound Designer II
You can also encode your surround mix directly to the Dolby Digital Professional (AC-3)
format, which is a very common compressed audio format for DVD-Video discs.
For more information about exporting projects, see Exporting Multitrack Projects.

Project Files
You can also deliver either an exported AAF file or a copy of the Soundtrack Pro project
file.
• AAF: Like the Final Cut Pro XML Interchange Format, Advanced Authoring Format (AAF)
is an industry-standard project interchange format that contains the editing decisions
of nonlinear editing projects.
• Soundtrack Pro project file: For the greatest flexibility, you could deliver the entire project
file with its associated media. This would allow for further adjustments in Soundtrack Pro,
as needed.
For information on saving projects, see Saving Multitrack Projects and Distributing a
Multitrack Project and Its Media Files Together.

Working with Video in
Soundtrack Pro

You can import a video into a multitrack or audio file project, view the video as you work
on your project, edit the video’s audio, and use markers to synchronize audio and video.
When you import a video, the video appears in the Video tab. When you import a video
into a multitrack project, a video clip also appears in a video track in the Timeline. The
video’s audio appears as a clip in an audio track in the Timeline and can be moved and
edited like other audio clips. You can mute, solo, and adjust the volume and pan of the
video’s audio, add effects, and automate changes. You can also open the video’s audio
in the File Editor and perform actions or analysis on it.
When you import a video, you can set the Time Ruler units to match the timecode format
of the video. Any Final Cut Pro markers contained in the video appear as markers in the
Soundtrack Pro Timeline. You can also add markers in Soundtrack Pro and export them
to Final Cut Pro with the video file. You can score markers to the playhead, using them
to synchronize your soundtrack to the action in the video.
You can work with video in Soundtrack Pro in several ways. You can add audio clips for
dialogue and voiceover, music, ambience, and sound effects to the Timeline. You can
make exchange files between Final Cut Pro and Soundtrack Pro as you work on both the
video and the soundtrack, or bring the final video into Soundtrack Pro to finalize the
project. When your soundtrack is complete, you can export it as an AIFF file or save it as
part of the video.

Supported Video File Formats
Soundtrack Pro supports standard QuickTime-compatible file formats. You can import a
QuickTime movie (.mov) video file into a Soundtrack Pro project and can import an MPEG-2
(.m2v) if you have installed the QuickTime MPEG-2 Playback Component. Video files using
NTSC, PAL, HD, and other formats supported by QuickTime can be imported into
Soundtrack Pro. Imported video files can be up to four hours in length.

Adding a Video to a Project
You can import a video file by dragging the file from a media tab or from the Finder. You
can import only one video file into a project.
To import a video file into a project
Do one of the following:

Chapter 14 Working with Video in Soundtrack Pro

The video is displayed in the Video tab in its correct aspect ratio, and a video clip appears
in the video track (the top track in the Timeline), letting you see the duration of the video
in the project. The video clip starts at the beginning of the project and cannot be moved
to another point in time. Any Final Cut Pro scoring markers included in the video file
appear in the Timeline with an orange handle.
If the video contains audio, new audio tracks are added below the video track for each
audio track in the movie, and the video’s audio tracks appear as audio clips in the new
tracks. You can move, resize, and edit these audio clips like any audio clip in the Timeline,
and can use the track controls to control volume and pan, mute or solo the track, and
add effects or automation.
Note: When you add a QuickTime movie containing video or a Broadcast Wave (BWF)
file to the File Editor, the Time ruler shows the file’s timecode format if the Time Ruler
Units menu item is set to either Frame or Non-drop Frame.

Playing the Video
When you play the project, the video plays in the Video tab in time with the audio in your
project. You can also control playback using keyboard shortcuts.
To view the video, you can make the Video tab active or detach it and move it to another
location onscreen. You can also view the video using an external video output device.

Controlling Video Playback Using Keyboard Shortcuts
There are a number of keyboard shortcuts you can use to control playback of the video
in the Video tab. To use keyboard shortcuts, the pointer cannot be in a text field.
• Space bar: Plays the video from the current playhead position. This is equivalent to
clicking the Play button.
• Return: Moves the playhead to the closest of the following items to the left of the
playhead: the beginning of the last playback start, the beginning of the cycle region,
or the beginning of the project. This is equivalent to clicking the Go to Beginning button
in the transport controls.
• Option–Left Arrow: Moves the playhead back (closer to the beginning) one video frame.
This is equivalent to clicking the Previous Frame button.

Chapter 14 Working with Video in Soundtrack Pro

357

• Option–Right Arrow: Moves the playhead forward (closer to the end) one video frame.
This is equivalent to clicking the Next Frame button.
• J, K, and L keys: You can use the keyboard commands (the J, K, and L keys) to speed
playback up to eight times normal speed. For complete information on using these
keys, see Using the J, K, and L Keys for Shuttling.
For a complete list of keyboard shortcuts, see Soundtrack Pro Keyboard Shortcuts.

Resizing the Video Tab
You can detach the Video tab and resize it (to any size, up to filling your entire screen).
To resize the Video tab
1 Detach (undock) the Video tab by clicking the tab at the top of the video frame and
dragging it from its pane.
2 Drag the resize control at the lower-right corner of the Video tab until the tab is the size
you want.

Use the window’s resize
control to make the
video larger.

Using Video Output Devices
You can connect an external video output device to your computer and play your project
through the video output device. This can be especially useful in cases where you are
using Soundtrack Pro as the final step in producing the overall project, or when you want
to show the current version of the project to a client or other party while working on the
project in Soundtrack Pro.
When you use an external video output device, the quality of the output is as high as the
device can support. If you connect an output device capable of broadcast-quality output,
the video is displayed with more accurate colors than on a computer display, with true
interlacing, correct pixel sizes, the correct aspect ratio, and broadcast-quality refresh rates.

Chapter 14 Working with Video in Soundtrack Pro

Some broadcast-quality video output devices receive both the video and audio from a
project. When you use a video output device that supports both video and audio output,
Soundtrack Pro automatically routes your audio output to this device to provide the best
possible synchronization of the audio and video.
You can also play a project’s video externally using Digital Cinema Desktop. Using Digital
Cinema Desktop, you can connect an Apple Cinema Display to your computer and play
the video full-screen through the Cinema Display while using another monitor for editing.
To play the video through a video output device, you must configure Soundtrack Pro to
use the device in Soundtrack Pro Video Out Preferences.
To configure Soundtrack Pro for a video output device
1 Choose Soundtrack Pro > Preferences, then click the Video Out button.

pop-up menu.
The menu lists only devices that are connected to your computer.
3 Optionally, select the Use Quarter-size Frames checkbox to reduce the frames sent to the
video output device. Sending quarter-size frames can result in better performance,
especially for devices using FireWire DV output.
4 Click the close button at the upper-left corner of the Preferences window to close the
window.
You can switch the output to the video output device on or off when the project is not
playing. The video appears in the Video tab whether output to the video output device
is switched on or off.

To switch off output to an external video output device
Choose View > Show > Show External Video.
If you have added the Video Out button to the Toolbar, you can also click the button to

Working with the Multipoint Video HUD
The following sections describe some examples of situations in which the Multipoint
Video HUD can provide useful context for your sound editing tasks on a video project.
Making a Selection in the Timeline or in the File Editor
When you make a selection of multiple clips or a Timeslice selection, the Multipoint Video
HUD displays the video frame at the start of the selection and the video frame at the end
of the selection.

Dragging a Clip into the Multitrack Timeline
When you drag a new clip into the Timeline, the Multipoint Video HUD displays the video
frame at the start of the clip and the video frame at the end of the clip.

Tip: You can also press the V key while dragging a clip to show the Multipoint Video HUD
just until you release the clip. Once you release the clip, the Multipoint Video HUD closes
automatically.
Dragging a Clip Around the Multitrack Timeline
When you drag an existing clip around in the Timeline, the Multipoint Video HUD displays
the video frame at the start of the clip on the left, the video frame at the end of the clip
on the right, and the video frame at the current pointer position in the middle. In the
case of dragging multiple clips, the first frame of video would be from the leading edge
of the earliest clip in time and the last frame of video would be for the trailing edge of
the last clip in time.

Chapter 14 Working with Video in Soundtrack Pro

363

For example, if you wanted to synchronize a gunshot sound with the frame in the video
when the flash from the gun is visible, you would first click the gunshot sound effect at
the point where the large transient can be seen in the waveform. Next, you would drag
the clip in the Timeline, pressing V while dragging, until you see the flash in the center
frame.

Resizing a Clip in the Multitrack Timeline
When you resize a clip in the Timeline, the Multipoint Video HUD displays the video frame
at the start of the clip and the video frame at the end of the clip. As you resize one edge
of the clip, that frame updates.
Nudging a Clip in the Multitrack Timeline
When you use the nudge keys to nudge a clip, the Multipoint Video HUD displays the
video frame at the start of the clip and the video frame at the end of the clip.
Horizontally Moving an Envelope Point in the Timeline and File Editor Project View
When you move an envelope point horizontally, the Multipoint Video HUD displays the
video frame at the current envelope point position. If you select multiple envelope points,
two or three frames are shown: one for the first envelope point, one for the last envelope
point, and one for the envelope point you are dragging, if it is not the first or last point.
Time Stretching in the File Editor
When you use the Time Audio Stretching tool, the Multipoint Video HUD displays a single
frame of video that follows the pointer location.
Dragging the Cycle Region
When you modify either end of the Cycle Region, the Multipoint Video HUD displays the
video frame at the start of the Cycle Region and the video frame at the end of the cycle
region. You can quickly remove the Cycle Region at any time by pressing Option-X.
Dragging Markers
When you drag a single marker, the Multipoint Video HUD displays the video frame at
the marker position. When you drag two markers, the Multipoint Video HUD displays the
video frames at both marker positions. When you drag three or more markers, the
Multipoint Video HUD displays three video frames: the first marker, the marker being
dragged, and the last marker.

Working with Automation

Automation offers a powerful way to add drama and interest to your projects. You can
automate volume and pan changes to tracks, busses, and submixes and automate changes
to effect and effect send parameters in multitrack projects. You can also automate volume,
pan, and effects changes in audio file projects.
In Soundtrack Pro, you can manipulate automation manually, or record changes and
movements made in either the application itself, or on a control surface. You can manually
add and adjust envelope points on envelopes in the Timeline and in the File Editor. You
can record changes over time to sliders, faders, and other controls in the Timeline, the
Mixer, and the Effects tab. You can also record movements with faders on a control surface
connected to your computer and mapped to Soundtrack Pro commands and functions.
This chapter covers the following:
• Working with Envelopes (p. 367)
• Recording Automation Data (p. 376)

Working with Envelopes
In the Timeline, each track, bus, and submix has a set of envelopes. The envelopes appear
as horizontal lines stretching across the length of the project directly below the track,
bus, or submix. You adjust an envelope by adding envelope points and moving the
envelope points to new values at different points in the Timeline.
For video editors accustomed to working in Final Cut Pro, envelopes provide the same
type of functionality as keyframes. The difference is that you can edit envelopes at a finer
level of precision than you can using keyframes, allowing extremely powerful control
over automated changes.

367

Track, Bus, and Submix Envelopes
Each track and bus has envelopes for volume and pan, and each submix has a volume
envelope. By default, the envelopes are hidden. When you show the envelopes, they
appear in rows below the track, bus, or submix in the Timeline.
Click the envelope
disclosure triangle.

The envelopes are
displayed below the
track, bus, or submix.

When you add effects to a track, bus, or submix, you can automate the effect parameters
by adding an envelope for any parameter to the envelopes for the track, bus, or submix.
The envelopes are different for each type of effect. For information on adjusting effect
parameters, see Working with Audio Effects.

To show the envelopes for a track, bus, or submix
Click the envelope disclosure triangle in the track header.
Click the disclosure triangle again to hide the envelopes.
Default Stereo Envelopes
The default envelopes for tracks using stereo panners are Volume and Pan. The ranges
of Volume and Pan envelopes are equivalent to the ranges of the corresponding track
controls:
• Volume envelopes: The range is from –96 dB to +6 dB.
• Track pan envelope: The range is from 100% Left to 100% Right pan, with Centered at
the midpoint, 0 (zero).
Default Surround Envelopes
The default envelopes for tracks using surround panners are as follows:
• Volume
• Surround Pan X
• Surround Pan Y
• Rotation
• Width
• Collapse

Command-click the selected envelope point.
Click in the automation row or somewhere else in the Timeline to deselect all selected
envelope points.

Moving Envelope Points
Once you add an envelope point, you can drag it up or down to change its value. As you
drag an envelope point up or down, its value appears to the right of the pointer. You can
drag an envelope point left or right to change its position in time. You can also select
and move multiple envelope points at the same time.
When you move an envelope point, the position of the envelope point snaps to the
closest Snap To position if snapping is turned on. For information on setting the Snap To
value, see Using Snapping.

To move an envelope point
Select the envelope point, then drag it to a new position.

To move an envelope point adjacent to another envelope point
1 Select the envelope point.
2 Hold down the Shift key and drag the envelope point to a position near another envelope
point.
Each envelope has an envelope point, at the beginning of the Timeline. You can make
adjustments by moving this envelope point up or down. If no envelope points have been
added, dragging the envelope’s handle adjusts the envelope for the entire project.

370

Chapter 15 Working with Automation

If you add more than one envelope point to an envelope, you can move envelope points
using the corresponding slider. When you move the slider, the envelope points closest
to the playhead (the closest before and the closest after) move by the same amount as
the slider.

Selecting and Moving Envelope Points with Clips
By default, when you select or move a clip in the Timeline, the associated envelope points
are not selected, and they do not move with the clip. You can set Soundtrack Pro to do
the opposite: to select associated envelope points when you select a clip. In this case, if
you move the clip, the envelope points move with it.

To select and move clips and envelope points together
Click the Select Envelope Points With Clips button at the top of the Timeline.

To select and move clips and envelope points independently of each other
Click the Select Only Clips button at the top of the Timeline.

Cutting, Copying, and Pasting Envelope Points
You can cut and copy selected envelope points and paste them at a different position in
the automation row.
When pasting envelope points, the following conditions apply:
• Envelope points can only be pasted into an envelope of the same type as the envelope
from which they were cut or copied. For example, envelope points from a volume
envelope can only be pasted into a volume envelope, not a pan or tempo envelope.
• Envelope points for an effect parameter can only be pasted into an envelope for exactly
the same effect parameter in exactly the same type of effect. You cannot paste envelope
points from one effect into another, even if they have parameters with the same name.

To cut envelope points
Select the envelope point, then choose Edit > Cut (or press Command-X).

To copy envelope points
Select the envelope points, then choose Edit > Copy (or press Command-C).

To paste envelope points
Set the playhead to the point where you want to paste the envelope points, then choose
Edit > Paste (or press Command-V).
When you paste envelope points into an automation row, the new envelope points
replace any existing envelope points, and the automation takes the shape of the cut or
copied envelope in the pasted area.
Pasting envelope points
into an envelope
replaces the existing area
of the envelope with the
cut or copied area.

Deleting Envelope Points
After listening to the results of your edits, you may decide to delete some envelope points.

374

Chapter 15 Working with Automation

To delete envelope points
1 Select the envelope points.
2 Do one of the following:
• Choose Edit > Delete (or press Command–X).
• Press the Delete key.
When you delete envelope points, the envelope adjusts accordingly, moving evenly from
the preceding envelope point to the next envelope point. If there are no other envelope
points, the envelope becomes horizontal, maintaining its initial value for the entire project.

Automating Effect and Send Parameters
You can automate effect parameters for tracks, busses, and submixes and for audio file
projects by adding envelopes for the effect parameters and then adding and adjusting
envelope points. You can also automate send parameters for tracks by adding an envelope
for the send parameters, then adding and adjusting envelope points.
To add an envelope for an effect or send parameter
1 Open the Effects tab and select the effect you want to automate.
2 In the Effect Parameters area, select the Auto checkbox for the parameter.

Click the Auto checkbox
for an effect parameter
to add an envelope for
the parameter.

To remove an envelope for an effect parameter

Master Bus
Each project has a Master bus that includes envelopes for volume, transposition, and
tempo. By default, only the Volume envelope is visible because Transposition and Tempo
are specifically for projects containing only tagged and looping clips.

The Master bus
envelopes appear
below the Master bus.

To show or hide the Master bus envelopes
Do one of the following:

µ

Click the Master bus disclosure triangle in the Timeline.
Choose Master Envelopes from the Show pop-up menu at the upper-right corner of the
Timeline.
Repeat the procedure to hide the Master bus envelopes.

To show the Transpose or Tempo envelopes
Choose Transpose or Tempo from the Show Envelopes pop-up menu in the Master bus
track header.
The ranges of the master envelopes are as follows:
• Master transpose envelope: Ranges from –12 semitones to +12 semitones.
• Master tempo envelope: Ranges from 60 bpm to 200 bpm.
For more information about the Master bus, see Using the Master Bus.

Recording Automation Data
In addition to working with envelopes, you can record automation data in Soundtrack Pro.
You can record movements you make to faders, sliders, and other onscreen controls using
the pointer. You can also connect a supported control surface to your computer and
record movements to controls and faders on the control surface. When you record
movements to onscreen controls or control surface controls, the corresponding envelope
in the Timeline (or File Editor) changes to display the recorded automation data. You can
edit the envelope to fine-tune the automation data after recording.

376

Chapter 15 Working with Automation

Automation Modes
Soundtrack Pro provides three modes for using and recording automation. The automation
modes determine whether automation data is recorded and what happens when you
release the control.
• Read: In Read mode, existing automation data is active when you play the project, but
no new automation data is recorded.
• Touch: In Touch mode, movements to controls are recorded when you play the project,
overwriting any existing automation data until you release the control. When you
release a control in Touch mode, the control returns to the value it previously had at
the point in the Timeline where you release the control. No envelope points after that
point are added or changed.
• Latch: In Latch mode, movements to controls are recorded when you play the project,
overwriting any data from the point you start recording until you stop playing the
project. When you release a control in Latch mode, the control maintains the same
value at which you released it.
To record automation data for movements to controls
1 Choose either Touch or Latch from the Automation Mode pop-up menu.
2 Set the playhead to a position before the point where you want to start recording.
3 Click Play (or press the Space bar) to start the project playing.
4 While the project plays, move the control you want to record.
Once you have recorded automation data, you can show the envelope for the control
and add and adjust envelope points on the envelope to fine-tune the automation. For
information on working with envelopes, see Working with Envelopes. For more information
on working with control surfaces, see Using Control Surfaces with Soundtrack Pro.

Thinning Envelope Points in Recorded Automation Data
Recording automation data can generate a large number of envelope points. The number
of envelope points recorded can make editing envelopes difficult, and in some cases
affect playback performance.
You can reduce or “thin” the number of envelope points recorded from a control surface
in the project preferences. You set the amount of thinning using the Automation Recording
Sensitivity slider. The automation data is thinned when you finish recording automation.
To set the amount of thinning
1 Choose Soundtrack Pro > Preferences, then click the General button.
2 In the General pane, drag the Automation Recording Sensitivity slider to adjust the amount
of thinning.

Chapter 15 Working with Automation

377

When the slider is set to High, no thinning occurs. The envelope contains every movement
of the control. Dragging the slider to any position other than High results in some thinning
of envelope points. By default, the slider is set to a moderate amount of thinning.
For more information about Soundtrack Pro project preferences, see Project Preferences.

Recording Audio in Soundtrack Pro

You can record your own audio on one or more tracks in the Timeline, the Mixer, or the
File Editor project view as a mono, stereo, or multichannel file. You get ready to record
by setting recording preferences and checking that your audio equipment is working.
For multitrack projects, you enable a track for recording or record audio in a new track.
You can record a single take or record multiple takes. If you record multiple takes, you
can review them after recording and choose which one to use in your project or assemble
a composite take using segments of each recorded take with the Multitake Editor.
This chapter covers the following:
• Getting Ready to Record (p. 379)
• Recording Audio in the Timeline (p. 380)
• Recording Audio in the Mixer (p. 387)
• Recording Audio in the File Editor Project View (p. 387)

Getting Ready to Record
Before you start recording, make sure that any audio equipment you plan to use in your
recording session (such as microphones, musical equipment, mixers, or external processors)
is connected to your computer and is working.
When you record, the recorded audio is saved to disk at the location set in the Recording
pane of the Preferences window. Audio files, while smaller than video files of comparable
duration, can be quite large (each minute of 16-bit, 44.1 kHz stereo audio requires roughly
10 MB of disk space), so you should make sure you have enough free disk space to store
your recordings before you start. You can set the input device and output monitoring
device for recording in the Preferences Recording pane, or change them in the Recording
tab. For detailed information on Recording preferences, see Recording Preferences.
For audio file projects, you record in the File Editor. When you record in the File Editor,
the recording replaces (overwrites) any audio over which you record. If you record for a
longer duration than the current length of the file, the file is lengthened to include the
recorded audio.

379

Recording Audio in the Timeline
You record in the Timeline by enabling a track for recording, setting the playhead, then
clicking Record. You can record a single take or record multiple takes by turning on cycling
before you start recording. When you finish recording, your recorded audio appears in a
track in the Timeline. If you record multiple takes, you can audition each take to choose
which one you want to use in your project. You can also assemble composite takes by
splitting and combining your recorded takes.

Enabling Tracks for Recording
Before you start recording, you enable the tracks you want to record to. You can record
audio only to tracks, not to busses or submixes. If no track is enabled for recording, a new
track is created below the existing tracks, and the take appears on the new track when
you click the Record button.
Note: For details on multitrack recording, see Multitrack Recording.
To enable a track for recording
Do one of the following:

Creating Podcasts in
Soundtrack Pro

Soundtrack Pro gives you the tools to create professional podcasts of your projects.
This chapter covers the following:
• About Podcasts (p. 389)
• Podcasting Media Production (p. 390)
• Displaying the Podcast Track and the Details Tab (p. 391)
• Podcast Marker Information in the Details Tab (p. 392)
• Adding Markers to a Podcast (p. 393)
• Adding Images to a Podcast (p. 396)
• Exporting Podcasts (p. 399)

About Podcasts
You can quickly and easily produce audio and video podcasts directly from within
Soundtrack Pro projects. And you can take video projects from Final Cut Pro and make
podcasts from them using Soundtrack Pro. Podcasts are audio and video broadcasts
available on the Internet. Unlike traditional radio and television shows with set schedules,
podcasts can be listened to at any time in the iTunes application or on an iPod. You can
even publish your podcast to iTunes and reach a potential audience of millions. Besides
democratizing what used to be known as radio, the podcasting movement provides new
avenues of distribution for recorded lectures and educational materials, audio tours of
museums, conference meeting updates, and so on.
Soundtrack Pro provides professional and prosumer podcasters the tools to create
extremely high-quality podcasts. And with the podcasting workflow built right into
Soundtrack Pro, audio post-production personnel can easily create versions of their sound
for picture mix or edit that are ready for iPod. This way, a small audience of clients and
colleagues can enjoy the convenience of listening to or watching the programs using
iPod or iTunes.

389

Podcasts fall into three broad categories:
• Audio-only podcasts: At the very least, a podcast contains an audio file. For information
about types of compressed audio files, see Exporting Audio Podcasts.
• Enhanced podcasts: The audio content may have one or more associated images and
web links that can be synchronized with the audio track. Also, chapter markers can be
embedded that allow listeners to jump to specific sections of the content.
• Video podcasts: Video podcasts typically include both video and audio content. The
technical requirements for video podcasts are more specific. For information about
video file formats for podcasting, see Exporting Video Podcasts.
Podcasts are typically published in a series of episodes. Soundtrack Pro supports the
creation of episodes.
You can add chapter markers, images, and web links to your podcasts using the podcast
track and the Details tab in Soundtrack Pro.
Note: If you want to make a simple audio or video podcast with no markers, images, or
web links, skip to Exporting Podcasts.

Podcasting Media Production
Producing podcasts has a lot in common with producing any other audio or video
program. Soundtrack Pro can help you with the audio production, editing, and mixing
steps as well as with some other tasks unique to podcasting.
There are two main ways to create podcasts:
• Take a Final Cut Pro project and create a podcast from it in Soundtrack Pro.
• Create a podcast from scratch in Soundtrack Pro.
Both of these scenarios involve some version of the following stages:
Stage 1: Recording the Sound (and Video)
There are many different ways to record a podcast, ranging from one-person shows, to
conference calls, to live events on location, to studio recordings. You can record multitrack
and multichannel sound directly into Soundtrack Pro, or you can import prerecorded files.
Stage 2: Editing and Mixing the Sound, Video, and Images
Soundtrack Pro gives you many specialized tools and powerful features that you can use
to create high-quality audio. And the ability to exchange projects and information between
Soundtrack Pro and Final Cut Pro makes video podcasting a very streamlined process.

390

Chapter 17 Creating Podcasts in Soundtrack Pro

Stage 3: Performing Podcast-Specific Editing and Authoring
Podcasts range in complexity from a simple audio or video file to enhanced podcasts
with chapter markers and associated web links. Besides its many sophisticated audio
editing and mixing tools, Soundtrack Pro includes a dedicated podcast track for adding
chapter markers, URL links, and images.
Stage 4: Compressing the Audio (and Video) Files
Soundtrack Pro includes a robust set of export and compression options for both audio
and video podcasting. For complete information about exporting from Soundtrack Pro,
see Exporting Multitrack Projects.
Stage 5: Uploading the Compressed Files
Once your podcast is complete, you upload the file to your web host using a file transfer
protocol (FTP) utility. You can trigger post-export actions (AppleScript documents) to do
this automatically as a part of the export process. For more information, see Using
Post-Export Actions.

Displaying the Podcast Track and the Details Tab
You use the podcast track in conjunction with the Details tab to add enhanced podcast
features to your podcast. Any Soundtrack Pro multitrack project can include information
on how to output the project as a podcast. This podcast-specific information can be
viewed and edited by showing the podcast track.

To display the podcast track
Choose Show > Podcast Track from the Show pop-up menu in the upper-right corner of
the Timeline.

Choose Podcast Track
from the Show pop-up
menu.

The podcast track appears near the top of the Timeline, just above the audio tracks.
By default, the podcast track appears just below the video track (if you have one in your
project) with a single blue podcast marker “region” that spans the entire length of the
project.

audience. Podcast markers are frames in a podcast that can display an image or a web
link synchronized to the audio in the podcast. Chapter markers are podcast markers that
provide enhanced navigation. Chapter markers make it easy for listeners and viewers to
skip ahead to the section they want. Chapter markers appear in the chapter list in both
iTunes and QuickTime Player. To adjust markers, including their respective web links and
images, see Podcast Marker Information in the Details Tab.

Chapter 17 Creating Podcasts in Soundtrack Pro

Note: Enhanced podcasts (using still images) and video podcasts are mutually exclusive.
Information for enhanced and video podcasts can co-exist in your multitrack project, but
you must choose one or the other when you export. See Exporting Podcasts for more
information.

Exporting Podcasts
After you have completed editing and mixing your project, including adding any
podcast-specific enhancements such as images, chapter markers, or web links, you are
ready to export your podcast.
Compression is an important step in exporting any audio or video podcast file. While it
is technically possible to distribute a podcast using standard (uncompressed) file formats,
it is not very practical nor very common. That’s because podcast files inevitably encounter
bandwidth bottlenecks as they travel to the far reaches of the Internet. So, when it comes
to podcasting, small is beautiful.

Exporting Audio Podcasts
Almost all audio-only podcasts use one of two compressed formats: AAC or MP3. In fact,
a podcast must use either the AAC or the MP3 format to be included in the iTunes Store.
AAC (also known as Advanced Audio Coding codec or MPEG-4/AAC) is a newer, more
efficient format. It provides more clarity than MP3 audio at the same bit rate with smaller
file sizes or files of the same size at higher quality.
For additional general information about exporting audio files see Exporting Multitrack
Projects.
Exporting Audio Podcasts as AAC Files
You can export AAC audio files directly from Soundtrack Pro by choosing File > Export
and choosing AAC/Podcast File from the File Type pop-up menu. For complete information
on exporting to the AAC format, see Exporting to AAC/Podcast Files.
Exporting Audio Podcasts as MP3 Files
You can export MP3 audio files directly from Soundtrack Pro. For complete information
on exporting to the MP3 format, see Exporting as MP3 Files.

Exporting Video Podcasts
While iTunes can play a wide variety of video formats, iPod only plays videos that are
created to exact specifications. The specifications include AAC for the audio portion and
one of two related formats (H.264 or MPEG-4) for the video portion. You want to make
sure that your video podcast is encoded correctly so that it will sync to iPod without issue.
Through links to its associated application, Compressor, Soundtrack Pro includes encoding
presets to make video podcasts that can play on iTunes, on a video iPod, or with Apple TV.

Chapter 17 Creating Podcasts in Soundtrack Pro

399

Exporting Video Podcasts Directly from Soundtrack Pro
To export a podcast that includes both video and audio, follow the instructions in Exporting
to AAC/Podcast Files. In step 6 of those export instructions, choose the third option: Video
Track.
This option results in an MPEG-4 (.m4v) file containing both video and audio. The properties
of the exported podcast file are equivalent to the H.264 for iPod Video 640x480 setting
that is included in the Compressor application. The resulting podcast file includes chapters
and web links if you specified them in Soundtrack Pro.
Using this method for exporting video podcasts offers the speed and convenience of
exporting directly from Soundtrack Pro. A tradeoff of this method is you don’t have as
much control over the various details of the transcoding process. For complete control
over all aspects of the transcode, including the various video parameters, use Compressor
(instead of this Export dialog). See Exporting Video Podcasts Using Compressor.
Exporting Video Podcasts Using Compressor
Compressor is the high-speed video and audio encoding tool for Final Cut Studio. You
can use it to convert content so that it can be experienced on many different platforms
and devices (including iTunes, Apple TV, and an iPod, among others).
The Export dialog in Soundtrack Pro offers a direct link to the Compressor application.
When you export using Compressor, you can use the presets included with Compressor
for your exported file or use custom presets that you create in Compressor. For detailed
information, see Exporting a Master Mix Using Compressor.
To export a video podcast using Compressor
1 Choose File > Export (or press Command-E).
2 Choose Master Mix from the Exported Items pop-up menu.
3 Choose Using Compressor from the File Type pop-up menu.
4 Select Encode Video.
5 In the associated pop-up menu, choose H.264 for Video Podcasting.
6 Click Export.
Note: You could also export your podcast project using the Preserve Video option
(retaining the video’s original format and exporting the audio as a standard, uncompressed,
AIFF file) and then import those files into Compressor for final transcoding. This method
gives you the most options in terms of transcoding decisions. For more information about
the Preserve Video option, see Exporting a Master Mix Using Compressor. Once you create
customized versions of the Compressor iPod presets, they are available in the
Soundtrack Pro export via Compressor options. For more information on working with
Compressor presets, see the Compressor User Manual.

Chapter 17 Creating Podcasts in Soundtrack Pro

Using Post-Export Actions for Podcast Production
The Soundtrack Pro Export dialog includes post-export actions that can automate parts
of your podcasting workflow and save you time and effort. You can use the feature to
automatically trigger your own AppleScript documents as a part of any export operation.
You can link your Soundtrack Pro podcast export to custom AppleScript documents that
would execute at the end of an export. For example, at the end of an overnight video
podcast transcode, Soundtrack Pro could automatically trigger a custom AppleScript
document that would transfer the exported podcast to a web server via scriptable FTP
software and send you (or a client) an email notification.
For more information about using post export-actions see Using Post-Export Actions.

Connecting Control Surfaces
There are a variety of control surfaces available for use with video and audio production
applications. Most control surfaces include faders, knobs, and buttons similar to those
found on a hardware mixing console, including channel strip controls for volume, pan,
mute, solo, and track selection, and a set of transport controls. Control surfaces also
typically provide buttons for selecting parameters to edit and for selecting different tracks
or banks of tracks, a jog wheel for moving the playhead precisely, and other controls.
Soundtrack Pro supports control surfaces that use the Mackie Control, Logic Control, and
Euphonix EuCon protocols to communicate with your computer.
To use a control surface, follow the process outlined below.
Important: When connecting a control surface or MIDI interface to your computer, read
the instructions included with the hardware, and install the latest version of any
appropriate firmware or driver software if needed. For more information, refer to the
documentation that came with the hardware.

Using Soundtrack Pro with Other
Applications

You can work with media files and projects from Final Cut Pro, DVD Studio Pro, Motion,
and other applications in Soundtrack Pro projects.
This chapter covers the following:
• Using Soundtrack Pro with Final Cut Pro (p. 409)
• Using Soundtrack Pro with DVD Studio Pro (p. 421)
• Using Soundtrack Pro with Motion (p. 423)
• Using Soundtrack Pro with Logic Pro (p. 424)
• Using Soundtrack Pro with Third-Party Applications (p. 425)

Using Soundtrack Pro with Final Cut Pro
You can use Soundtrack Pro for every aspect of creating audio for a project, from multitrack
recording to advanced audio processing and mixing. For example, you can send a clip’s
media file directly from Final Cut Pro to Soundtrack Pro, modify it, and then immediately
see the changes to your clip back in Final Cut Pro. You can also batch process audio files
using AppleScript documents created in Soundtrack Pro. However, one of the most
powerful advantages of using Soundtrack Pro is the ability to send entire sequences to
Soundtrack Pro and automatically conform them each time you make editorial changes
to a sequence in Final Cut Pro. For more information, see Using Conform with Final Cut Pro.

About Soundtrack Pro Audio File Projects
A Soundtrack Pro audio file project allows you to edit and process an audio media file
nondestructively, which means you can always alter or remove all of the actions you
applied and even get back to the original state of the audio. A Soundtrack Pro audio file
project is stored in a special Mac OS X format called a package (or bundle). A Mac OS X
package appears to be a single file in the Finder but actually contains a collection of files,
such as the original audio file, render files, and the list of actions applied to your audio
file. To take advantage of nondestructive editing, you can create a Soundtrack Pro audio
file project by either saving one from Soundtrack Pro or sending a clip or clips from
Final Cut Pro to a Soundtrack Pro audio file project.

409

Methods for Sending Audio from Final Cut Pro to Soundtrack Pro
You can take several approaches to working with your Final Cut Pro project’s audio in
Soundtrack Pro. The method you choose depends on your situation.
Do you need to make specific changes to audio clips in your project?
Final Cut Pro allows you to open one or more clips in the Soundtrack Pro File Editor, where
you can analyze and process the audio using a variety of powerful tools.
Do you need to batch process multiple audio files?
Using customizable Soundtrack Pro scripts, you can automate repetitive audio processing
tasks such as removing clicks, adding fades, or normalizing levels.
Do you need a complete audio post-production solution for your movie, including
sound editing, sweetening, and mixing?
You can send multiple Final Cut Pro clips—or even an entire sequence—to a
Soundtrack Pro multitrack project, where you can complete your final mix by adding
additional tracks of sound effects, voiceover, and music. Both stereo and surround sound
mixing are supported.

Sending Audio Clips from Final Cut Pro to Soundtrack Pro
There are three methods you can use to open a clip in the Soundtrack Pro File Editor:
• Send a clip item or items to Soundtrack Pro as a Soundtrack Pro audio file project: A
Soundtrack Pro audio file project is created for each item. This allows you to
nondestructively make changes to the audio in the Soundtrack Pro File Editor. The
original clips in Final Cut Pro are automatically reconnected to the new Soundtrack Pro
audio file projects. You have the option to copy the entire media file for each clip item,
or you can create trimmed versions with handles. For more information, see Sending
Clips from Final Cut Pro to the Soundtrack Pro File Editor.
• Process a clip with a Soundtrack Pro script: The clip opens in the File Editor, the actions
in the script are performed automatically, the clip is saved with the changes, and the
File Editor moves to the background so you can continue working in Final Cut Pro. If
your clip’s media file is a standard audio or video file, you have the option to create a
new Soundtrack Pro audio file project, so as to process the file nondestructively. If you
don’t take advantage of this option, the script processes the source media destructively
(permanently). If your clip’s media file is already a Soundtrack Pro audio file project,
the changes are nondestructive. For more information, see Processing a Clip’s Media
File with a Soundtrack Pro Script.
• Open a clip’s media file destructively in the Soundtrack Pro File Editor: If you do not use a
Soundtrack Pro audio file project for editing and you save the changes to the file in its
native format, or in any flat audio file format (such as AIFF, WAVE, and so on), any
changes you make to the audio file are destructive (permanent). For more information,
see Opening a Final Cut Pro Clip’s Media File in Soundtrack Pro.

410

Chapter 19 Using Soundtrack Pro with Other Applications

Sending Clips from Final Cut Pro to the Soundtrack Pro File Editor
When you send an audio clip from Final Cut Pro to the Soundtrack Pro File Editor, a
Soundtrack Pro audio file project is created with the file extension “.stap.” This file can be
edited nondestructively. The Final Cut Pro clip is reconnected to the new Soundtrack Pro
audio file project, so the original media file is not affected by what you do in the File
Editor. You can send single clips or multiple clips to Soundtrack Pro audio file projects.

Sending Linked Clips from Different Media Sources
You cannot send one or more audio clips from Final Cut Pro to Soundtrack Pro as audio
file projects that contain audio linked from different media sources.
Examples of audio linked from different media sources include:
• Audio captured in Final Cut Pro as mono clips that are later linked as stereo pairs or
multichannel clips
• An audio clip linked to video from a different media file
• An audio clip linked to audio from a different audio file
With linked media, you must either send the clip or clips from Final Cut Pro to
Soundtrack Pro as a multitrack project, or you must first unlink the media files in
Final Cut Pro. For more information on sending clips from Final Cut Pro to Soundtrack Pro
as a multitrack project, see Sending a Final Cut Pro Sequence or Clip Selection to a
Multitrack Project. For more information on modifying linked media in Final Cut Pro,
see the Final Cut Pro User Manual.
To send a single Final Cut Pro clip to the Soundtrack Pro File Editor
1 Do one of the following:
• Select the clip in the Final Cut Pro Browser or Timeline, then choose File > Send To >
Soundtrack Pro Audio File Project.
• Control-click the clip in the Final Cut Pro Browser or Timeline, then choose Send To >
Soundtrack Pro Audio File Project from the shortcut menu.

c Select “Send only referenced media” to copy only the used section of the media
(between the In and Out points) to the new Soundtrack Pro audio file project.
This is recommended unless you intend to edit the entire source file.
d To add media handles when the “Send only referenced media” option is selected, enter
handle durations in the In Handle and Out Handle fields.
3 Click Save.
A Soundtrack Pro audio file project is created and opened in the Soundtrack Pro File
Editor. The Final Cut Pro clip is reconnected to the new Soundtrack Pro audio file project
instead of its original media file.
4 Modify the audio as needed.
5 Choose File > Save to save the project with the changes.
A dialog appears allowing you to choose whether the Soundtrack Pro audio file project
should include a copy of the original audio media file or simply refer to it.

412

Chapter 19 Using Soundtrack Pro with Other Applications

6 Choose one of the following, then click OK.
• Include Source Audio: This option copies the original audio media file into the
Soundtrack Pro audio file project package. Because the audio file project has its own
copy of the original media, it is self-contained and doesn’t rely on any external audio
files. This option simplifies media management and makes it easier to transfer the audio
file project to other computers. However, this increases the project file size and therefore
requires more disk space.
• Reference Source Audio: This option creates a link to the original source audio file,
resulting in a smaller project file. However, to use this project file, you always need to
keep track of the original source audio file. If you accidentally delete the original media
file, the Soundtrack Pro audio file project can no longer play back. Choose the Reference
Source Audio option only if the media is in a shared location accessible from any
computer you might use to access the Soundtrack Pro audio file project.
When you return to Final Cut Pro, the clip now connects to the new Soundtrack Pro audio
file project.
To send multiple Final Cut Pro clips to Soundtrack Pro
1 Select multiple clips in the Final Cut Pro Browser or Timeline.
2 Do one of the following:
• Choose File > Send To > Soundtrack Pro Audio File Project.
• Control-click the selection, then choose Send To > Soundtrack Pro Audio File Project
from the shortcut menu.
3 In the Save dialog, choose a location to save the new Soundtrack Pro audio file projects.
To create a new folder, press Command-Shift-N, enter a name for the folder, then click
Create.
4 Click OK.
A Soundtrack Pro audio file project is created for each clip selected in Final Cut Pro. Each
Soundtrack Pro audio file project is then opened in a File Editor tab in Soundtrack Pro.

Processing a Clip’s Media File with a Soundtrack Pro Script
Soundtrack Pro scripts are AppleScript droplets containing Soundtrack Pro File Editor
actions. Scripts can be created in Soundtrack Pro or a script editing application such as
Script Editor, the AppleScript application included with Mac OS X.
When you send a Final Cut Pro clip’s media to a Soundtrack Pro script, the following steps
occur for each unique file:
• With your consent, Final Cut Pro generates a Soundtrack Pro audio file project and
replaces the clip’s media file with it.
• The audio file project or the clip’s media file opens in the Soundtrack Pro File Editor.

Chapter 19 Using Soundtrack Pro with Other Applications

413

• The script actions are applied to the audio file project or the media file.
• The audio file project or the clip’s media file is saved with the changes.
If your clip’s media file is a standard audio or video file, you have the option to create a
new Soundtrack Pro audio file project so as to process the file nondestructively. If you
don’t take advantage of this option, the script processes the source media destructively
(permanently). If your clip’s media file is already a Soundtrack Pro audio file project, the
changes are nondestructive.
To modify one or more clips’ media files using a Soundtrack Pro script
1 Select the clips in the Final Cut Pro Browser or Timeline.
2 Do one of the following:
• Choose File > Send To > Soundtrack Pro Script.
• Control-click the selection, then choose Send To > Soundtrack Pro Script from the
shortcut menu.
3 Choose the script you want to use from the submenu.
Note: If you have not created custom Soundtrack Pro scripts and saved them to the
default Soundtrack Pro script location, no scripts appear in the submenu.
By default, a dialog appears offering to convert each clip’s media file to a Soundtrack Pro
audio file project, which allows for nondestructive editing.
4 Choose one of the following options:
• Yes: Creates a Soundtrack Pro audio file project for each clip and then prompts you for
a location to save these project files. You can create a new folder by pressing
Command-Shift-N.
• No: This option edits the files destructively, making permanent changes to the original
media files.
• Cancel: Cancels the script operation.
Soundtrack Pro opens and each clip is automatically opened, edited, saved, and closed
in the File Editor.
You can also repeat the last script you used to edit a clip, making it easy to edit several
clips with the same set of actions.

To edit a clip with the last script used
Control-click the clip in the Final Cut Pro Browser or Timeline, then choose Send To > Last
Soundtrack Pro Script from the shortcut menu.

To disable the dialog that appears when you use the Send To Soundtrack Pro Script
command
1 Choose Final Cut Pro > User Preferences, then click the Editing tab.

414

Chapter 19 Using Soundtrack Pro with Other Applications

2 Deselect the Warn on “Send to Soundtrack Pro Script” option, then click OK.

Opening a Final Cut Pro Clip’s Media File in Soundtrack Pro
You can open a Final Cut Pro clip’s media file directly in the Soundtrack Pro File Editor by
choosing the Open in Editor command or by opening the file from the Finder.
Important: In either of these cases, if you make changes in the Soundtrack Pro File Editor
and save those changes to the original file, your changes will be destructive and
permanent. To edit nondestructively, you can save the file as a Soundtrack Pro audio file
project and import that file into Final Cut Pro.
You can specify that audio clips open in Soundtrack Pro when you choose the Open in
Editor command. This ensures that Final Cut Pro automatically opens Soundtrack Pro
when you choose the command and that, when you return to Final Cut Pro, the clip is
automatically reconnected to the updated media file. You can also choose Soundtrack Pro
for editing video files if you work with a lot of linked video and audio clip items. For more
information, see the Final Cut Pro User Manual.
To set Soundtrack Pro as the default application to open Final Cut Pro audio clips
1 In Final Cut Pro, choose Final Cut Pro > System Settings, then click the External Editors
tab.
2 Make sure that Soundtrack Pro is the application set to open audio files.
To open a Final Cut Pro audio clip’s media file directly in the Soundtrack Pro File Editor
1 Control-click the audio clip in the Final Cut Pro Browser or Timeline, then choose Open
in Editor from the shortcut menu.
The audio clip’s media file opens in the Soundtrack Pro File Editor.
2 In Soundtrack Pro, modify the audio as needed.
3 Choose File > Save to save the file with the changes.
The Save dialog appears.
4 By default, the File Type pop-up menu is set to Audio File Project, which saves the changes
nondestructively. If you wish to permanently modify the original file, choose the original
file type and filename. Soundtrack Pro will ask if you’re sure you want to overwrite the
file. Click OK only if you’re sure that you no longer need your unedited media.
5 Click Save.
6 If you saved the file with a different filename or different file type, you must manually
add the new file to your Final Cut Pro sequence.
Important: Unless you save a Soundtrack Pro audio file project, this is a destructive process
that permanently modifies the original file.

Chapter 19 Using Soundtrack Pro with Other Applications

415

Creating Multitrack Projects from Final Cut Pro Clips or Sequences
Soundtrack Pro multitrack projects are similar to Final Cut Pro projects: they contain
multiple audio tracks in a Timeline that you can use to arrange clips in sequence. Like
Final Cut Pro sequences, clips in a multitrack project refer to media files stored elsewhere,
so the project file size stays small. Multitrack projects also contain a single video track for
synchronizing your audio to picture.
Multitrack projects have track controls for volume, pan, mute, solo, effects, and effect
parameters. You can create additional audio busses and submixes for grouping signals
from audio tracks together or for effect sends. Tracks, busses, and submixes can be
exported to individual audio files or to a stereo or multichannel mixdown. These
Soundtrack Pro features are particularly useful for creating stem mixes that you can send
back to Final Cut Pro.
You can create a Soundtrack Pro multitrack project from a selection of Final Cut Pro clips
or an entire sequence. The multitrack project opens automatically in the Soundtrack Pro
Timeline, and clips appear just as they did in your Final Cut Pro sequence, complete with
level and pan settings and crossfades. The project tab in Soundtrack Pro displays the
name of the Final Cut Pro sequence from which the project was exported. In
Soundtrack Pro, you can arrange your clips, add effects, and create a finished mix. The
final mix can be exported from Soundtrack Pro and automatically imported into
Final Cut Pro in sync with your original sequence.
Note: Some information from Final Cut Pro is not included in the multitrack project, such
as pan settings for stereo pairs, generators, and effects applied to clips.

Sending a Final Cut Pro Sequence or Clip Selection to a Multitrack Project
Creating a Soundtrack Pro multitrack project from within Final Cut Pro is a simple process.
To create a multitrack project from a sequence or a group of clips
1 Select a sequence in the Final Cut Pro Browser, or select multiple clips in the Timeline.
2 Do one of the following:
• Choose File > Send To > Soundtrack Pro Multitrack Project.
• Control-click the selection, then choose Send To > Soundtrack Pro Multitrack Project
from the shortcut menu.

• Open in Soundtrack Pro Multitrack Editor: Select this option to open the multitrack project
in Soundtrack Pro after it is created.
• Include Background Video: Select this option to render the video in your Final Cut Pro
sequence. The Soundtrack Pro multitrack project will refer to this file in its video track
so you can see your video while you edit. Select what kind of background video you
want to export:
• Fully Rendered Video (slow): Your entire sequence is rendered at full quality to a
QuickTime movie file. This option is recommended if the project is to be moved to
another computer.
• Base Layer Video (fast): Any sequence segment that requires rendering in Safe RT
mode (in other words, any segment with a red render bar) is exported without effects.
These files are not portable to a different computer. For more information, see the
Final Cut Pro User Manual.
• Save project with latest clip metadata (recommended): Select this option to ensure an
accurate change history by having Final Cut Pro automatically save the project after
the send process.
4 Enter a project name or keep the default name, then click Save.

Using Soundtrack Pro with Third-Party Applications
You can use Soundtrack Pro to exchange media and project files with third-party
applications.

Exchanging OMF and AAF Files with Other Applications
When you “send” a Final Cut Pro sequence to a Soundtrack Pro multitrack project, you
are using the Final Cut Pro XML Interchange Format to transfer the data between the two
applications. Open Media Framework (OMF) and Advanced Authoring Format (AAF) are
two industry-standard project interchange formats that Soundtrack Pro can use to share
projects and import the editing decisions from other (third-party) video and audio editing
applications. You can also export a multitrack project from Soundtrack Pro as an AAF file.
For more information on sending Final Cut Pro sequences to Soundtrack Pro multitrack
projects, see Using Soundtrack Pro with Final Cut Pro.
Importing OMF and AAF Files
You can import OMF and AAF Files into Soundtrack Pro.
To import an OMF file
1 Choose File > Import OMF.
The Import OMF dialog appears.
2 Use the dialog to select the file and click Import OMF.
A progress bar shows that the file is being translated and the project opens in
Soundtrack Pro.
To import an AAF file
1 Choose File > Import AAF.
The Import AAF dialog appears.
2 Use the dialog to select the file and click Import AAF.
A progress bar shows that the file is being translated and the project opens in
Soundtrack Pro.
The multitrack projects created from importing OMF and AAF files include any available
pan and volume information.
Using OMF and AAF Files
The OMF and AAF formats provide a way to consolidate all of the audio files and audio
edits from a third-party video or audio editing application into one portable package.
The picture editor can choose to include handles (extra footage beyond the In and Out
points of a clip that provides a safety margin in case you need it during the sound edit
and mix).

Chapter 19 Using Soundtrack Pro with Other Applications

425

Here are some things to keep in mind when using OMF and AAF files:
• OMF and AAF exports generally omit unused media to keep the overall file size low. If
you want to “steal” a performance from another take, you might be out of luck with
an OMF or AAF export.
• OMF or AAF exported files are usually truncated. If a music piece was edited into many
small clips during the picture edit, the OMF and AAF export process applies those edits
permanently on the file level. Sound editors usually prefer to have one original piece
of music with (nondestructive) edits referring to it.
• It is always a good idea to have single-frame “sync pops” at the top and tail of the video
and every single audio track to verify synchronization.
• OMF and AAF files do not include video, so usually a video file needs to be exported
separately.
• To exchange OMF and AAF files with ProTools, you will need DigiTranslator, the
Digidesign interchange application, which is sold separately.
• Volume automation and panning automation are not always included in OMF and AAF
files.
• OMF and AAF exports often include audio files with very long and complicated
filenames.
• OMF and AAF exports support a single sample rate. All the audio files in a single export
must have the same sample rate.
• OMF packages (that contain media) are limited to a 2 GB maximum file size.
Exporting to AAF
You can export Soundtrack Pro multitrack projects as AAF files.
To export a project to an AAF file
1 Choose File > Export AAF.
The Save dialog appears.
2 In the Save dialog, enter a name for the file, then navigate to the location where you
want to save it, then click Save.

Manually Creating Audio File Project and File Links
When working with applications that do not link to Soundtrack Pro audio file projects, it
is useful to manually create a relationship between an audio file and an audio file project.
Once this is done, every time you save the audio file project, a new copy of the flat file is
saved at the same time.
To manually create a link between an audio file and an audio file project
1 Open the audio file you wish to link to an audio file project.
2 Choose File > Save (or press Command–S).

426

Chapter 19 Using Soundtrack Pro with Other Applications

The Save dialog appears.
3 In the Save dialog, enter a name for the file, then navigate to the location where you
want to save it, then click Save.
An audio file project is created with the name you entered.
4 Choose File > Save a Copy As (or press Command–Control–S).
The Save dialog appears.
5 In the Save dialog, navigate to the location of the original file, then select the file.
6 Choose the type of the original source file from the File Type pop-up menu.
7 Click Save.
8 Choose File > Save As (or press Command–S).
The Save dialog appears.
9 In the Save dialog, navigate to the location of the original audio file project.
10 Select the Update Flat Copy checkbox.
11 Click Save.
Every time the audio file project is saved, a new copy of the flat file is saved at the same
time.

Using Exported Audio Files with Other Applications
You can open an audio file exported from Soundtrack Pro (a project mix; an exported
track, bus, or submix; or an audio file project) in any application that supports audio files.
If you save an audio file project as an AIFF file or a QuickTime movie, a link is included in
the AIFF file or movie, letting you reopen the project in Soundtrack Pro and make changes
to action settings and other edits.
If you export a saved multitrack project using File > Export, a link is included in the
exported file, letting you reopen the multitrack project in Soundtrack Pro and make
changes. The project must have been previously saved at least once before you export
the project mix.
When you reopen the exported file, a dialog appears, asking if you want to open the
audio file or the original project. In the dialog, click Open Project.
The multitrack project opens in the Soundtrack Pro Timeline so you can continue working.
When you are finished working in Soundtrack Pro, be sure to save the multitrack project
before exporting a project mix so your changes are retained.

About Exporting
You can export a project to a mono, stereo, or multichannel audio file. You can export
all, or selected, tracks, busses, or submixes to either stereo or multichannel audio files, or
to groups of mono files. And you can create as many mixes of your project as you like by
selecting or muting tracks, busses, and submixes; adjusting controls, effects, and envelopes;
and then exporting each version as a separate mix.
The Soundtrack Pro Export dialog includes a variety of post-export actions that can
automatically open the exported files in a Final Cut Pro sequence or in File Editor project
view, place exported files on new tracks, or export a mix to Motion, Logic, or Waveburner.
You can also add your own custom AppleScript actions using the Export dialog.
To streamline your workflow, you can create custom export presets with any combination
of exported items, file types, bit depths, sample rates, and post-export actions.

Export File Formats Available in Soundtrack Pro
Export file formats include the following standard audio file types:
• AIFF
• WAVE
• NeXT
• Sound Designer II
• MP3
• AAC/Podcast
• Dolby Digital Professional (AC-3)
Note: Dolby Digital Professional encoding is available only on computers that have
Final Cut Studio installed.
• AAF
You can also export a project to a variety of formats using Compressor, the Final Cut Studio
transcoding application. And you can save a multitrack project with all of the media files
it uses together in the same folder.

About Export Options
The Export dialog in Soundtrack Pro is a flexible tool that provides numerous alternatives
for your workflow and distribution needs.

There are several export options that are available no matter which format you choose
to export.

General Options
The following options are available for any format you choose to export.
• Filename: You can enter a filename for the exported file.
• Location: You must choose a location for the exported file.
• Preset pop-up menu: You can create custom export presets with any combination of
exported items, file types, bit depths, sample rates, and post-export actions. For more
information about using export presets and the Preset pop-up menu, see Using Export
Presets.
• Exported Items pop-up menu: Choose to export a master mix or export the component
parts of your multitrack project as individual files or as groups of files.
For more information about exporting the component parts of your multitrack project,
see Exporting Tracks, Busses, and Submixes Separately.
• Master Mix: Also called a project mixdown. This is a single audio file that contains all
of the elements and settings in your multitrack project. When you export a master
mix, all unmuted tracks, busses, and submixes that are routed to hardware output
jacks are included in the exported file. You can exclude any tracks, busses, and
submixes from the exported mix by muting them. For more information about
exporting a master mix, see Exporting a Master Mix.
• Selected Tracks, Busses, and Submixes: Exports selected tracks, busses, and submixes
only. If nothing is selected, each unmuted track, bus, and submix is exported as a
separate file.

432

Chapter 20 Exporting Multitrack Projects

• All Tracks, Busses, and Submixes: Exports each unmuted track, bus, and submix as a
separate file.
• All Tracks: Exports each unmuted track as a separate file.
• All Busses: Exports each unmuted bus as a separate file.
• All Submixes: Exports each unmuted submix as a separate file.
• File Type pop-up menu: Choose the file type for the exported audio file or files. For more

About Export Options for AIFF, WAVE, and Other Formats
In addition to the general options for all export formats (see General Export Options), the
following options are available when you export to the AIFF, WAVE, NeXT, or Sound
Designer II formats.

• Create multiple mono files checkbox: Select this checkbox to export a separate audio
file for each output channel in your multitrack project. For more information, see About
Exporting Multiple Mono Files.
• Bit Depth pop-up menu: Choose a bit depth for the exported file.
• Sample Rate pop-up menu: The sample rate is the number of times an analog signal is
measured—or sampled—per second. The higher the sample rate, the higher the quality
and the larger the file size, but don’t choose a sample rate higher than the rate used
in your multitrack project or you’ll waste space.

434

Chapter 20 Exporting Multitrack Projects

About MP3 Export Options
In addition to the general options for all export formats (see General Export Options), the
following options are available when you export as an MP3 file.

• Stereo Bit Rate pop-up menu: The higher the mono or stereo kilobits per second (Kbps),
the higher the audio quality and the larger the file size. The most common bit rate for
stereo MP3 files is between 128 Kbps and 192 Kbps. Lower bit rates are more appropriate
for sound files containing voice recordings (as opposed to music).
Some example settings and uses include:
• 32 kbps: AM radio quality, suitable for medium-quality speech
• 96 kbps: FM radio quality, suitable for high-quality speech or medium-quality music
• 128 kbps: Suitable for good-quality music
• 256 kbps and 320 kbps: Suitable for music that is near audio CD quality
• Use Variable Bit Rate Encoding (VBR) checkbox: This setting varies the number of bits
used to store the music depending on the complexity of the music. This can help keep
file size to a minimum.
• Sample Rate pop-up menu: The sample rate is the number of times an analog signal is
measured—or sampled—per second. The higher the sample rate, the higher the quality
and the larger the file size, but don’t choose a sample rate higher than the rate used
in your multitrack project or you’ll waste space.
• Channels pop-up menu: If your project is monaural or if the target playback device is
mono, choose Mono. (Mono files are about half the size of stereo files.) If your project
output is in stereo and the target playback device is stereo, choose Stereo.

Chapter 20 Exporting Multitrack Projects

435

• Joint Stereo checkbox: When deselected, your MP3 files contain one track for the right
stereo channel and one track for the left. In many cases, the two channels contain
related information. When the Joint Stereo checkbox is selected, one channel carries
the information that’s identical on both channels, and the other channel carries the
unique information. At bit rates of 160 Kbps and below, this can improve the sound
quality of your converted audio.
• Smart Encoding Adjustments checkbox: Select this to have Compressor analyze your
encoding settings and music source, and then adjust settings to maximize quality.
• Filter Frequencies Below 10 Hz checkbox: Filtering inaudible frequencies results in smaller,
more efficient files without perceptible loss of quality.

About AAC/Podcast Export Options
In addition to the general options for all export formats (see General Export Options),
there are additional options when you export as AAC/Podcast files. The AAC/Podcast
export options are divided into three separate panes: Audio, Streaming, and Podcast.

About Options in the Audio Pane for AAC/Podcast Export
The following export options are available in the Audio pane:

• Channels pop-up menu: Choose either mono or stereo for the exported media file.
• Sample Rate pop-up menu: Choose from one of the following sample rates: 8, 11.025,
12, 16, 22.050, 24, 32, 44.1, or 48 kHz. You can also choose Recommended to have
Soundtrack Pro automatically choose a sample rate that is suitable for the Channels
and Bit Rate settings.

436

Chapter 20 Exporting Multitrack Projects

• Quality pop-up menu: Choose one of the following for the audio quality of your output
media file:
• Low: This allows for fast transcoding, but at the expense of output file quality.
• Medium: The audio quality is better than Low, but this takes longer to transcode.
• High: This is the best audio quality setting available. Use this setting when the audio
quality is important for the output media file and you don’t mind how long it takes
to transcode.
• Bit Rate slider and field: Move the slider to set the overall audio bit rate for an exported
media file between the range of 16 Kbps (2 KB/sec.) to 256 Kbps (32 KB/sec.), or enter
a specific number in the accompanying field.

About Options in the Streaming Pane for AAC/Podcast Export
The following export options are available in the Streaming pane:

• Streaming hints enabled checkbox: Make sure that this box is selected if you want the
MPEG-4 Part 2 output format streaming settings to be applied.
• QuickTime Streaming Server Compatibility (pre v4.1) checkbox: Select this checkbox if
you want your exported file to work with an older QuickTime Streaming Server (version
4.1 or earlier). You don’t need to select this box if you are using a newer version of
QuickTime, because any streaming compatibility issues are automatically resolved.
• Maximum Packet Size field: Enter a number to specify the largest file size allowable (in
bytes) for a streaming packet in your output media file. The packet size you choose
should be no larger than the largest packet used on any network between the streaming
server and the viewer.
• Maximum Packet Duration field: Enter a number to specify the longest duration allowable
(in milliseconds) for a streaming packet in your output media file. The duration affects
MPEG-4 Part 2 audio only. It limits the maximum amount of audio (in milliseconds) in
any packet, which limits the audio dropout created by the loss of a packet.

About Dolby Digital Professional (AC-3) Export Options
In addition to the general options for all export formats (see General Export Options),
there are additional options when you export as Dolby Digital Professional (AC-3) files.
The Dolby Digital Professional (AC-3) export options are divided into three separate panes:
Audio, Bitstream, and Preprocessing.

About Options in the Audio Pane
The following export options are available in the Audio pane:

• Target System pop-up menu: Available settings are limited to those appropriate for the
selected target system. If you’re encoding for use with DVD Studio Pro, choose DVD
Video. Choose DVD Audio only if you are encoding for use in a DVD Audio authoring
application. Choose Generic AC-3 to remove the setting limits.

Chapter 20 Exporting Multitrack Projects

439

• Audio Coding Mode pop-up menu: Specifies the audio channels of the encoded stream.
The audio coding mode affects settings such as the available bandwidth and surround
channel preprocessing.

Choose the audio
channel grouping for
the encoded stream
from the Audio Coding
Mode pop-up menu.

For example, “3/2 (L, C, R, Ls, Rs)” means three front channels (left, center, right) and
two rear (surround) channels. “2/0 (L, R)” is essentially a standard stereo file. If you
choose the Automatic setting, Compressor makes its best guess at the intended audio
coding mode, based on available source audio files.
Note: “S” stands for a single rear “Surround” channel.

• Enable Low Frequency Effects checkbox: Select this option to include the LFE channel in
the encoded stream.
Note: This option is not available for 1/0 mono or 2/0 stereo.
• Sample Rate pop-up menu: Specifies the sample rate. All files intended for video and
audio DVD authoring must have a 48 kHz sample rate as per the DVD specification. The
32 kHz and 44.1 kHz sample rates are only available when Generic AC-3 is the target
system.

440

Chapter 20 Exporting Multitrack Projects

• Data Rate pop-up menu: The choices depend on the coding mode and target system.
The higher the rate, the better the quality. Dolby Digital Professional (AC-3) streams
have a constant data rate. At 448 kbps, which is the default for 5.1 encoding, one minute
of AC-3 audio takes about 3.3 MB of storage space. For stereo encoding, rates of 192 kbps
and 224 kbps are typical and will produce good results.
• Bit Stream Mode pop-up menu: Defines the purpose of the encoded audio material. The
information is included in the finished stream and can be read by some decoding
systems.
• Dialog Normalization field: Specifies the average volume of the dialogue, using decibels
of full scale (dBFS), in your sound files relative to full modulation. The playback device
uses this information to maintain similar volume among different AC-3 streams. The
goal is to make all AC-3 encoded audio files have the same listening level, regardless
of the source file.
It is especially important to properly use the Dialog Normalization feature if you have
different audio files (with different volume levels) going on to a DVD. If you know the
average level for each of them, enter that number in the Dialog Normalization field for
each file. For example, if the dialogue in your project averages around –12 dB on the
level meter, enter –12 in the Dialog Normalization field.
Note: This normalization is between the audio streams on the DVD, not within an
individual audio stream itself.
You can enter values from –1 dBFS to –31 dBFS. The louder the source file, the smaller
the value you enter, and the more the audio in the encoded file is attenuated during
playback.
The difference between the value you enter and 31 dBFS (which represents the normal
dialogue listening level) is the amount that the source audio is attenuated. For example:
• If you enter –31 dBFS: The attenuation is 0 dB (31 dBFS–31 dBFS), and the source
audio levels are not affected at all.
• If you enter –27 dBFS: The attenuation is 4 dB (31 dBFS–27 dBFS).
• If you enter –12 dBFS: The attenuation is 19 dB (31 dBFS–12 dBFS).
Important: It is critical that you have set the Dialog Normalization setting correctly if
you intend to use any of the Compression Preset settings. The Compression Preset
settings assume that the audio, after the dialogue has been normalized, is at the normal
listening level of 31 dBFS. Levels that are consistently louder than that result in distorted
sound and erratic levels.
If you want to ensure that the AC-3 encoder does not affect your sound levels, enter
–31 for the Dialog Normalization and choose None from the Compression Preset pop-up
menu (located in the Preprocessing pane).

Chapter 20 Exporting Multitrack Projects

441

About Options in the Bitstream Pane
These settings are stored in the finished stream for use by the playback device. Leave
them at their default values unless you have a specific technical reason for changing
them. The following export options are available in the Bitstream pane:

• Center Downmix and Surround Downmix pop-up menus: If your encoded audio has these
channels, but the player does not, the channels are mixed into the stereo output at
the specified level.
• Dolby Surround Mode pop-up menu: When encoding in 2/0 (stereo) mode, specifies
whether the signal uses Dolby Surround (Pro Logic).
• Copyright Exists checkbox: Select this option to specify that a copyright exists for this
audio.
• Content is Original checkbox: Select this option to specify that this audio is from the
original source and not a copy.
• Include Audio Production Information: Select this checkbox and fill in the fields below
to specify how the encoded audio content was mixed. Playback devices may use this
information to adjust output settings.
• Peak Mixing Level field: Specifies peak sound pressure level (SPL) (between 80 dB and
111 dB) in the production environment when this mix was mastered.
• Room Type pop-up menu: Specifies information about the mixing studio.

442

Chapter 20 Exporting Multitrack Projects

About Options in the Preprocessing Pane
Preprocessing options are applied to the audio data before encoding. With the exception
of the Compression Preset setting, leave these settings at their default values unless you
have a specific technical reason for changing them. The following export options are
available in the Preprocessing pane:

• Compression Preset pop-up menu: Specifies one of the dynamic range processing modes
built in to the Dolby Digital Professional (AC-3) format. The default of Film Standard
Compression should only be used when you are encoding an original mix intended for
cinema. In almost all cases, you should choose None.

Choose a compression
setting from the
Compression Preset
pop-up menu.

Important: It is critical that you have set the Dialog Normalization setting correctly in
the Audio pane if you intend to use any of these Compression Preset settings. The
Compression Preset settings assume that the audio, after the dialogue has been
normalized, is at the normal listening level of 31 dBFS. Levels that are consistently
louder than that result in distorted sound and erratic levels.
Note: If you are building a Dolby Digital Professional 5.1 channel surround sound DVD,
you will use Film Standard Compression.
• General: Select the Digital Deemphasis checkbox to specify whether input audio data
is pre-emphasized and needs to be de-emphasized before encoding.
• LFE Channel: Select the Low-Pass Filter checkbox to apply a 120 Hz low-pass filter to
the Low Frequency Effects (LFE) channel. Turn off this filter if the digital signal fed to
the LFE’s input does not contain information above 120 Hz.

Chapter 20 Exporting Multitrack Projects

• Full Bandwidth Channels: You can select two options:
• Low-Pass Filter checkbox: Select this option to turn on a low-pass filter with a cutoff
near the available audio bandwidth that is applied to the main input channels. If the
digital signal fed to the main input channels does not contain information above the
available audio bandwidth, you can turn off this filter. Compressor automatically
determines the available bandwidth.
• DC Filter checkbox: Select this option to turn on a DC high-pass filter for all input
channels as a simple way to remove DC offsets. Most mixed audio material is already
free of DC offsets.
• Surround Channels: You can select two options:
• 90° Phase-Shift checkbox: Select this option to generate multichannel AC-3 streams
that can be downmixed in an external 2-channel decoder to create true Dolby
Surround-compatible output.
• 3 dB Attenuation checkbox: Select this option to apply a 3 dB cut to the surround
channels of a multichannel film soundtrack being transferred to a consumer home
theater format. Cinema surround channels are mixed 3 dB “hot” (higher) relative to
the front channels to account for cinema amplifier gains.

About Export Options Using Compressor
In addition to the general options for all export formats (see General Export Options),
there are additional options when you export using Compressor.
Note: Because Soundtrack Pro can tap the power of Compressor as a background process,
many of these export options are identical to the corresponding options in the Compressor
application.

• Format to Export Video: These settings allow you to choose settings for your video
export.
• Preserve Video button: This allows you to export the video in its original format. Once
you select this option, you must then choose an export preset from the adjacent
preset pop-up menu. A summary of the preset appears below it in the dialog. When
you export, the video is copied unchanged to the exported file. For more information,
see Using Compressor Export Presets.

444

Chapter 20 Exporting Multitrack Projects

• Encode Video button: This allows you to export the video in a different format. Once
you select this option, you must then choose an export preset from the adjacent
preset pop-up menu. A summary of the preset appears below it in the dialog. For
more information, see Using Compressor Export Presets. Encoding the video
transcodes it to the new export format. Transcoding the video can take longer than
copying and can result in a loss of quality. In most cases, when the video format of
the exported file is the same as the source video, you should preserve the video
when exporting. If the video format of the exported file is different than the source
video, you should encode the video when exporting.
• Edit Channel Layout button: If you are exporting a multichannel project and want to
change the channel layout for the exported file, click this button and the Channel
Layout dialog appears. For more information, see Exporting Multichannel Projects with
Compressor.
• Edit Presets button: If you wish to edit Compressor presets used for export, click this
button and Compressor opens. For more information, see Using Compressor Export
Presets and the Compressor User Manual.

Exporting Part of a Multitrack Project
You can export just a portion of your multitrack project by selecting it with the cycle
region.
To select a portion of a multitrack project with the cycle region
Do one of the following:

Drag in the bottom half of the Time ruler from the beginning of where you want the cycle
region to the end.

Position the playhead and press I to set the cycle region In point. Position the playhead
and press O to set the cycle region Out point.

Press X to set the cycle region In and Out points at the boundaries of the clip that currently
intersects the playhead. The clip on the uppermost selected track is used.

Exporting a Master Mix
A master mix (or project mixdown) is a single audio file that contains all of the elements
and settings in your multitrack project. When you export a master mix, all unmuted tracks,
busses, and submixes that are routed to hardware output jacks are included in the
exported file. You can exclude any tracks, busses, and submixes from the exported mix
by muting them. For more information about routing to hardware output jacks, see
Setting Hardware Outputs and Setting the Submix Outputs to Surround.

Setting Submix Outputs
By default, all submix outputs in Soundtrack Pro are set to Surround 1-6. This setting
affects how audio signals are routed and how files are exported from multitrack projects.
Use the Output pop-up menu in each submix to choose an output channel or set of
output channels. Your choice defines the output of that submix (and any files exported
from that submix) as either mono, stereo, or surround.
If you export a master mix using multiple submixes, the output channel or set of output
channels of the first submix defines the channels used for the output of the exported file
as either mono, stereo, or surround.

Exporting a Master Mix to a Standard Audio File
You can export a mixdown of your project to any of the following standard (uncompressed)
audio formats: AIFF, WAVE, NeXT, and SoundDesigner II.
To export a master mix as a standard audio file
1 Choose File > Export (or press Command-E).
The Export dialog appears.

2 If you want, choose an export preset to export a master mix from the Preset pop-up
menu.

446

Chapter 20 Exporting Multitrack Projects

For more information, see Using Export Presets.
3 Choose Master Mix from the Exported Items pop-up menu.
4 Use the File Type pop-up menu to choose a file type for the exported audio file.
If you choose any of the last four menu items (MP3 File, AAC/Podcast File, Dolby Digital
Professional (AC-3) File, or Using Compressor), the central section of the Export dialog
displays options for the selected format type. For information about these menu items,
see Exporting a Master Mix.
5 To export a separate mono audio file for each output channel in your multitrack project,
select the “Create multiple mono files” checkbox.
For more information, see About Exporting Multiple Mono Files.
6 Choose a bit depth for the exported file from the Bit Depth pop-up menu.
7 Choose a sample rate for the exported file from the Sample Rate pop-up menu.
8 If you like, use the After Export pop-up menu to choose a post-export action.
For more information, see Using Post-Export Actions.
9 Enter a name for the exported file, then navigate to the location where you want to save
the file.
10 Click Export.
Note: When you bounce or export a project with an effect tail (sound that extends past
the end of the audio file, usually caused by reverb or another effect), the length of the
tail is limited to a maximum of 30 seconds. If the tail extends beyond this amount of time,
it is cut off after 30 seconds in the bounced or exported file.

Exporting as MP3 Files
MP3 is a specific type of MPEG encoding known formally as MPEG audio layer 3. MP3 uses
perceptual audio coding and psychoacoustic compression to remove all superfluous
information (specifically the redundant and irrelevant parts of a sound signal that the
human ear doesn’t hear anyway). The result is that MP3 encoding shrinks the original
sound data from a CD (with a data rate of 1411.2 kilobits per one second of stereo music)
by a factor of 12 (down to 112–128kbps) without sacrificing very much sound quality.
Proponents of MP3 claim there is no sacrifice in sound quality, but audio professionals
can usually hear the difference on good equipment.
To export a master mix as an MP3 file
1 Choose File > Export (or press Command-E).
The Export dialog appears.
2 If you want, choose an export preset from the Preset pop-up menu.
For more information, see Using Export Presets.

For more information, see Using Post-Export Actions.
7 Enter a name for the exported file, then navigate to the location where you want to save
the file.
8 Click Export.

Exporting to AAC/Podcast Files
AAC (Advanced Audio Coding) provides audio encoding that compresses much more
efficiently than older formats, such as MP3, yet delivers higher-quality results with smaller
file sizes. AAC is the default audio format for the iPod and iTunes, as well as the default
audio codec for the .m4v format used in all video files sold on iTunes.
To export a master mix as an AAC/Podcast file
1 Choose File > Export (or press Command-E).
The Export dialog appears.
2 If you want, choose an export preset from the Preset pop-up menu.
For more information, see Using Export Presets.

8 If you like, use the After Export pop-up menu to choose a post-export action.
For more information, see Using Post-Export Actions.
9 Enter a name for the exported file, then navigate to the location where you want to save
the file.
Output files are given the same names as the tracks, busses, or submixes being exported.
For example, “Track 1” results in “Track 1.aif.” If you select the “Create multiple mono files”
checkbox, the Mixer object name (for example, “Track 1”) serves as the base name to
which channel codes are appended (for example, “Track 1.R.aif” and “Track 1.L.aif”). For
more information, see About Exporting Multiple Mono Files.
10 Click Export.
When you export a project, track, bus, or submix that includes an effect (for example, a
reverb or delay) that produces a tail that extends past the end of the project, the exported
file lengthens to include the tail.
You can also select part of an audio file and add an effect to a selection. When you add
an effect that produces a tail to a selection, the tail is blended with the audio following
the selection until the effect level falls below –96 dB. The project lengthens to include
the tail if necessary.

About Exporting Multiple Mono Files
You can select the “Export multiple mono files” checkbox to export a separate mono
audio file for each output channel in your multitrack project. If you do this, a separate
audio file for each hardware output (jack) is created.

Chapter 20 Exporting Multitrack Projects

455

For example, by default, all tracks are routed to Submix 1, and Submix 1 is routed to the
Stereo 1, 2 outputs. With this setup, selecting the “Export multiple mono files” checkbox
exports two mono files. The letter L is appended to the filename of the left mono file,
and the letter R is appended to the right mono file.

If the Output pop-up menu is set to Surround >1-6, six mono files are exported, each
with the corresponding code appended to its filename: L, R, C, LFE, Ls, and Rs.

For more information about routing to hardware output jacks, see Connecting Physical
Outputs and Setting the Submix Outputs to Surround.

Exporting to AAF
Advanced Authoring Format (AAF) is an industry-standard project interchange format
for sharing projects and editing decisions between different video and audio editing
applications. For more information on using AAF files, see Exchanging OMF and AAF Files

Using Post-Export Actions
The Export dialog includes post-export actions that can automate parts of your workflow
and save you time and effort. The post-export actions range from opening the exported
files in a Final Cut Pro sequence to bouncing mixes to new tracks. You can also use the
feature to automatically trigger your own AppleScript documents as a part of any export
operation. Soundtrack Pro comes with a set of default actions (see General Export Options).

You can save a series of actions in the File Editor as an AppleScript droplet. Those droplets
will appear as actions in the After Export pop-up menu (provided you save them to the
default location: /Users/username/Library/Scripts/Soundtrack Pro Scripts/). For more
information about creating your own AppleScript droplets in Soundtrack Pro, see Scripting
Actions in the File Editor Project View.
You can also add your own AppleScript scripts (that you create outside of Soundtrack Pro)
to this default location, and they will appear in the After Export pop-up menu. Such
custom actions could include an AppleScript script to send an email notification or to
automatically transfer the exported file to a web server.

Custom actions
appear here.

For information about writing AppleScript scripts, go to the following websites:
• Apple developers: Go to http://developer.apple.com/applescript.
• General Apple customers: Go to http://macscripter.net.

Chapter 20 Exporting Multitrack Projects

457

To add your own AppleScript scripts to the After Export pop-up menu
1 Confirm that your AppleScript script uses the following syntax (to ensure that it works in
the After Export pop-up menu):
on run argv
repeat with anItem in argv
set posixItem to POSIX file anItem

Using Conform with Final Cut Pro

One of the biggest hurdles faced by sound editors is dealing with picture changes. When
a picture editor moves clips or changes edit durations, the sound editor receives the new
edit and then must manually conform the sound mix to the new picture edit. This process
is time-consuming and it’s easy to make mistakes. Worse, manually conforming a mix
distracts a sound editor from the most important job at hand: completing the mix.
This chapter covers the following:
• About Conforming Manually (p. 463)
• About Soundtrack Pro Conform (p. 463)
• Conforming a Soundtrack Pro Multitrack Project (p. 464)
• Reviewing and Approving Changes in a Conform Result Project (p. 468)

About Conforming Manually
When manually conforming a sound mix to a new picture cut, a sound editor imports
the picture editor’s new audio clips into an existing multitrack project on new tracks.
Next, the sound editor has to walk through the new edits one by one, comparing the old
placement of clips to the new ones. Clips in the old mix must be adjusted so that they
line up with new cuts in the video. Clips may also need to be deleted or added because
a shot was cut or added.

About Soundtrack Pro Conform
Soundtrack Pro Conform makes conforming multitrack projects much more efficient. The
picture editor and sound editor can work in parallel and then use Conform to easily merge
the results of their work.
Here is how a picture editor and a sound editor might work together using Conform:
• A Final Cut Pro sequence is sent to a Soundtrack Pro multitrack project.
• Changes and edits are made in parallel to both the Final Cut Pro sequence and the
Soundtrack Pro multitrack project. The Soundtrack Pro project that the sound editor
uses is referred to as the “original” audio mix.

463

• An “updated” send is performed to provide Soundtrack Pro with a new version of the
project containing the edits performed in Final Cut Pro. This creates a second
Soundtrack Pro multitrack project, referred to as the “updated project.”
• When you initiate Conform, Soundtrack Pro analyzes both the “original” audio mix and
the “updated” send from Final Cut Pro, including all possible clip moves and media
changes and generates a third project, referred to as the “result” project, that has every
change made with the highest confidence. For more information, see Conforming a
Soundtrack Pro Multitrack Project.
• You can use the Conform interface to review, modify, and approve all the changes
needed to best perform the process of editing the audio mix to match the new project.
For more information, see Reviewing and Approving Changes in a Conform Result
Project.

Conforming a Soundtrack Pro Multitrack Project
This section shows you how to conform a multitrack project to changes that were made
to the source sequence in Final Cut Pro.
To conform a Soundtrack Pro multitrack project to changes made to the source
sequence in Final Cut Pro
1 Select a sequence in the Final Cut Pro Browser.
2 Do one of the following:
• Choose File > Send To > Soundtrack Pro Multitrack Project.
• Control-click the selection, choose Send To from the shortcut menu, then choose
Soundtrack Pro Multitrack Project from the submenu.
3 In the Save dialog that appears, confirm that the “Save project with latest clip metadata
(recommended)” checkbox is selected.

Select the “Save project
with latest clip metadata
(recommended)” checkbox.

464

Chapter 21 Using Conform with Final Cut Pro

This ensures an accurate change history by having Final Cut Pro automatically save the
project after the sequence is sent to Soundtrack Pro. If you are planning to use Conform
frequently, the “Save project with latest clip metadata (recommended)” checkbox should
always be selected.
4 Click Save.
For more information on sending sequences to Soundtrack Pro, see Creating Multitrack
Projects from Final Cut Pro Clips or Sequences.
5 At this point, changes and edits are made in parallel to both the Final Cut Pro sequence
and the Soundtrack Pro multitrack project:
• Sound editor: Makes changes to the Soundtrack Pro multitrack project. This project is
referred to as the “original” audio mix project.
• Picture editor: Makes changes to the Final Cut Pro sequence.
6 In Final Cut Pro, do one of the following:
• Choose File > Send To > Soundtrack Pro Multitrack Project.
• Control-click the selection, choose Send To from the shortcut menu, then choose
Soundtrack Pro Multitrack Project from the submenu.
7 In the Save dialog that appears, confirm that the “Save project with latest clip metadata
(recommended)” checkbox is selected, then enter a new name for the multitrack project
and click Save.

Select “Save project
with latest clip metadata
(recommended)” checkbox.

This creates a new Soundtrack Pro project that will be referred to as the “updated” project.
8 Make sure that both the “original” audio mix project and the “updated” project are open
in Soundtrack Pro.

Chapter 21 Using Conform with Final Cut Pro

9 Do one of the following:
• Choose File > Conform Projects.
• Open the Conform tab, then click the Conform Projects button.
This initiates the conform process.
10 In the dialog that appears, do the following:
a Select the “original” audio mix project (the “sound editor version”) on the left.
b Select the “updated” project (the more recent send from Final Cut Pro—the “picture
editor version”) on the right.

Note: Only projects that have embedded Final Cut Pro clip metadata (projects sent from
Final Cut Pro or opened via XML documents) appear in this dialog.
11 Determine whether Soundtrack Pro should make comparisons during the conform to
filenames only, then do one of the following:
• If the conform should make comparisons based the filename only, make sure the “Only
Compare Backing File Filenames (instead of full path names)” checkbox is selected.
• If the conform should follow full pathnames, make sure the “Only Compare Backing
File Filenames (instead of full path names)” checkbox is deselected.
If the “Only Compare Backing File Filenames (instead of full path names)” checkbox is
deselected, Soundtrack Pro makes comparisons against the files and file path names as
well. For example, an original Soundtrack Pro audio mix file is located in
/users/username/Documents/ and the filename is “conform (sent).stmp.” If the checkbox
is selected, Soundtrack Pro ignores the full path name, and just compares the filename
itself. If the checkbox is deselected, Soundtrack Pro follows the full path name during the
conform.
12 Click Continue.
Soundtrack Pro analyzes the clip positions in your “original” audio mix and the clip
positions in the “updated” picture edit from Final Cut Pro, and determines the best
position/duration and media to use for each clip. Soundtrack Pro will attempt to conform
the audio mix from the “original” project to match the video from the “updated” project.

Reviewing and Approving Changes in a Conform Result Project
Once you have a Conform worklist, you can inspect the changes, reviewing the playback
in the original, updated, or result projects, and can change and accept choices for each
clip individually or multiple clips or groups of clips all at once. The goal is to walk through
the changes made to generate the result project and verify that all the clips have been
moved into the correct positions and that the correct choices have been made to satisfy
the artistic goals for the audio mix. At any time, you are free to accept all the changes
made by Soundtrack Pro and finish the conform process.

Filtering Out Unchanged Clips
For many clips, the Position/Duration and Media may be unchanged (the clips were the
same in both versions of the project). These show up as “Not Changed” in the Conform
worklist. It can be useful to filter out all the unchanged clips so that you can concentrate
on reviewing the clips that actually moved or had media changes.

To filter out unchanged clips from the Conform worklist
Select the Hide Unchanged checkbox.

Select Hide Unchanged.

Hide Unchanged selected.

Unchanged clips are removed from the worklist. Only clips that have changed remain in
the worklist.

468

Chapter 21 Using Conform with Final Cut Pro

Using the Project Selector Buttons
Use the Project Selector buttons to select one of three projects to appear in the main
multitrack Timeline. This is helpful if you want to go back to your sound edit (the “original”
project) to quickly see where a clip or group of clips was, then go to the result project
and preview those same clips to verify that they correctly match the picture. By default,
once the Conform process starts, the multitrack Timeline will show the untitled result
project, ready for you to review each clip or group of clips in the worklist.

To use the Project Selector buttons to display a project
Click the Original, Updated, or Result button.

Click a Project Selector
button to display the
corresponding project
in the Timeline.

The corresponding project appears in the multitrack Timeline.

Grouping Clips in the Conform Worklist
It can be useful to group clips together in the Conform worklist. You can use the Group
slider to control how clips are grouped together. When you click clips or groups, the
selected clips (or clips in the selected group) are highlighted in the mini timelines.
Groups in the
Conform work list

To automatically form groups in the worklist
Drag the Group slider to the right.

To reduce or remove groups from the worklist
Drag the Group slider to the left.
If you drag the slider all the way to the left, you will remove all groups and you can work
with individual clips.

Chapter 21 Using Conform with Final Cut Pro

469

Sliding the group slider to the right will automatically form groups of clips.

Showing Selected Clips in the Timeline
If the Show Selected Clip in the Timeline button (the magnifying glass zoom button to
the right of the project selector) is selected, as clips or groups are selected in the worklist,
the main Timeline will scroll and zoom to show the selected group or clips or both.
Show Selected Clip in
the Timeline button

Approving Changes and Clips
The objective of this part of the conform process is to work through all of the clips on
the worklist and verify that the clips are in the correct position.
It can be useful to start with the clips that have the lowest confidence value. To do this,
you can click the header of the Confidence column and sort in ascending order. This way,
you’ll get the clips with the lowest confidence at the top. You can then click a clip and
see the different options for position/duration and media.
To audition and approve changes and clips in the result project
1 Select the “Show selected clip in the Timeline” button.
For details, see Showing Selected Clips in the Timeline.
2 Click Result in the Project Selector buttons to display the result project in the main
multitrack Timeline.
3 Click a clip in the worklist and audition the clip in the main Timeline of the result project
to verify the correct position.
4 In the Details section, select an option for the clip.

470

Chapter 21 Using Conform with Final Cut Pro

When you select a clip with more than one position, duration, or media option, the clip
will immediately move to that selected location so that you can audition that choice in
the main Timeline.

Approve button
Clip options

Note: When the clip moves, any automation that might exist on the track will move with
the clip.
5 Once you are satisfied with your choice, click the Approve button.
The clip is marked with a green checkmark, indicating that it has been reviewed and
approved in the result project.
Note: The process of reviewing and approving changes is simply a tool to help you go
through the worklist of clips.
6 Optionally, you can select multiple clips or select a group and then click Approve to
approve all selected clips.

Filtering Out Approved Clips
Once you have a number of clips or groups that you have approved, you may find it
useful to select the Hide Approved filter. With this filter selected, clips will pop off the
worklist as you approve them, helping you focus attention on the clips that need to be
reviewed and approved.

To filter out approved clips from the Conform worklist
Select the Hide Approved checkbox.

Approved clip

Select the Hide
Approved checkbox.
Approved clips

Chapter 21 Using Conform with Final Cut Pro

471

Approved clips are removed from the worklist. Only clips that are not approved remain
in the worklist.

Finishing the Conform Process
Once you are satisfied that all the clips in the result project are in the correct place, you
can click the Finish button to end the Conform process. You are not required to approve
every single clip. In fact, the approvals do not change the outcome of the Conform process:
the updated project will have all the clips set to their currently selected position, duration,
and media regardless of whether the selection is approved or not. The approval process
is more of a tool to help you manage your progress through the worklist.

To finish the Conform process
Click Finish.
The result is an Untitled project containing the conform results. This project can be saved
and edited just like any other project. Typically, you will use this result project for
subsequent audio edits in Soundtrack Pro. If more changes are made in Final Cut Pro, the
result project from your first conform (plus any edits you’ve made in Soundtrack Pro) can
be used as the “Original” project in a subsequent conform process. It will be conformed
to an even more recent send from Final Cut Pro.

Appendix

Audio Fundamentals

This appendix discusses the broad topics of sound and digital audio in order to provide
some background information for using Soundtrack Pro.
This appendix covers the following:
• What Is Sound? (p. 487)
• Digital Audio (p. 497)

What Is Sound?
All sounds are vibrations traveling through the air as sound waves. Sound waves are
caused by the vibrations of objects and radiate outward from their source in all directions.
A vibrating object compresses the surrounding air molecules (squeezing them closer
together) and then rarefies them (pulling them farther apart). Although the fluctuations
in air pressure travel outward from the object, the air molecules themselves stay in the
same average position. As sound travels, it reflects off objects in its path, creating further
disturbances in the surrounding air. When these changes in air pressure vibrate your
eardrum, nerve signals are sent to your brain and are interpreted as sound.

Fundamentals of a Sound Wave
The simplest kind of sound wave is a sine wave. Pure sine waves rarely exist in the natural
world, but they are a useful place to start because all other sounds can be broken down
into combinations of sine waves. A sine wave clearly demonstrates the three fundamental
characteristics of a sound wave: frequency, amplitude, and phase.

Amplitude

–

Time

1 ms

487

Frequency
Frequency is the rate, or number of times per second, that a sound wave cycles from
positive to negative to positive again. Frequency is measured in cycles per second, or hertz
(Hz). Humans have a range of hearing from 20 Hz (low) to 20,000 Hz (high). Frequencies
beyond this range exist, but they are inaudible to humans.
Amplitude
Amplitude (or intensity) refers to the strength of a sound wave, which the human ear
interprets as volume or loudness. People can detect a very wide range of volumes, from
the sound of a pin dropping in a quiet room to a loud rock concert. Because the range
of human hearing is so large, audio meters use a logarithmic scale (decibels) to make the
units of measurement more manageable.
Phase
Phase compares the timing between two similar sound waves. If two periodic sound
waves of the same frequency begin at the same time, the two waves are said to be in
phase. Phase is measured in degrees from 0 to 360, where 0 degrees means both sounds
are exactly in sync (in phase) and 180 degrees means both sounds are exactly opposite
(out of phase). When two sounds that are in phase are added together, the combination
makes an even stronger result. When two sounds that are out of phase are added together,
the opposing air pressures cancel each other out, resulting in little or no sound. This is
known as phase cancelation.

488

Appendix B Audio Fundamentals

Phase cancelation can be a problem when mixing similar audio signals together, or when
original and reflected sound waves interact in a reflective room. For example, when the
left and right channels of a stereo mix are combined to create a mono mix, the signals
may suffer from phase cancelation.

Separate signals

In phase

Out of phase

Mixed signals

Frequency Spectrum of Sounds
With the exception of pure sine waves, sounds are made up of many different frequency
components vibrating at the same time. The particular characteristics of a sound are the
result of the unique combination of frequencies it contains.
Sounds contain energy in different frequency ranges, or bands. If a sound has a lot of
low-frequency energy, it has a lot of bass. The 250–4000 Hz frequency band, where humans
hear best, is described as midrange. High-frequency energy beyond the midrange is called
treble, and this adds crispness or brilliance to a sound. The graph below shows how the
sounds of different musical instruments fall within particular frequency bands.

Mid

Time

Appendix B Audio Fundamentals

489

Note: Different manufacturers and mixing engineers define the ranges of these frequency
bands differently, so the numbers described above are approximate.
The human voice produces sounds that are mostly in the 250–4000 Hz range, which likely
explains why people’s ears are also the most sensitive to this range. If the dialogue in
your movie is harder to hear when you add music and sound effects, try reducing the
midrange frequencies of the nondialogue tracks using an equalizer filter. Reducing the
midrange creates a “sonic space” in which the dialogue can be heard more easily.
Musical sounds typically have a regular frequency, which the human ear hears as the
sound’s pitch. Pitch is expressed using musical notes, such as C, E flat, and F sharp. The
pitch is usually only the lowest, strongest part of the sound wave, called the fundamental
frequency. Every musical sound also has higher, softer parts called overtones or harmonics,
which occur at regular multiples of the fundamental frequency. The human ear doesn’t
hear the harmonics as distinct pitches, but rather as the tone color (also called the timbre)
of the sound, which allows the ear to distinguish one instrument or voice from another,
even when both are playing the same pitch.

Appendix B Audio Fundamentals

Musical sounds also typically have a volume envelope. Every note played on a musical
instrument has a distinct curve of rising and falling volume over time. Sounds produced
by some instruments, particularly drums and other percussion instruments, start at a high
volume level but quickly decrease to a much lower level and die away to silence. Sounds
produced by other instruments, for example, a violin or a trumpet, can be sustained at
the same volume level and can be raised or lowered in volume while being sustained.
This volume curve is called the sound’s envelope and acts like a signature to help the ear
recognize what instrument is producing the sound.

Percussive volume envelope

Measuring Sound Intensity
Human ears are remarkably sensitive to vibrations in the air. The threshold of human
hearing is around 20 microPascals (μP), which is an extremely small amount of atmospheric
pressure. At the other extreme, the loudest sound a person can withstand without pain
or ear damage is about 200,000,000 μP: for example, a loud rock concert or a nearby jet
airplane taking off.
Because the human ear can handle such a large range of intensities, measuring sound
pressure levels on a linear scale is inconvenient. For example, if the range of human
hearing were measured on a ruler, the scale would go from 1 foot (quietest) to over
3000 miles (loudest)! To make this huge range of numbers easier to work with, a
logarithmic unit—the decibel—is used. Logarithms map exponential values to a linear
scale. For example, by taking the base-ten logarithm of 10 (101) and 1,000,000,000 (109),
this large range of numbers can be written as 1–9, which is a much more convenient
scale.
Because the ear responds to sound pressure logarithmically, using a logarithmic scale
corresponds to the way humans perceive loudness. Audio meters and sound measurement
equipment are specifically designed to show audio levels in decibels. Small changes at
the bottom of an audio meter may represent large changes in signal level, while small
changes toward the top may represent small changes in signal level. This makes audio
meters very different from linear measuring devices like rulers, thermometers, and
speedometers. Each unit on an audio meter represents an exponential increase in sound
pressure, but a perceived linear increase in loudness.

Appendix B Audio Fundamentals

Important: When you mix audio, you don’t need to worry about the mathematics behind
logarithms and decibels. Just be aware that to hear incremental increases in sound volume,
exponentially more sound pressure is required.
What Is a Decibel?
The decibel measures sound pressure or electrical pressure (voltage) levels. It is a
logarithmic unit that describes a ratio of two intensities, such as two different sound
pressures, two different voltages, and so on. A bel (named after Alexander Graham Bell)
is a base-ten logarithm of the ratio between two signals. This means that for every
additional bel on the scale, the signal represented is ten times stronger. For example, the
sound pressure level of a loud sound can be billions of times stronger than a quiet sound.
Written logarithmically, one billion (1,000,000,000 or 109) is simply 9. Decibels make the
numbers much easier to work with.
In practice, a bel is a bit too large to use for measuring sound, so a one-tenth unit called
the decibel is used instead. The reason for using decibels instead of bels is no different
from the reason for measuring shoe size in, say, centimeters instead of meters; it is a more
practical unit.

Decibel Units
Audio meters are labeled with decibels. Several reference levels have been used in audio
meters over the years, starting with the invention of the telephone and evolving to present
day systems. Some of these units are only applicable to older equipment. Today, most
professional equipment uses dBu, and most consumer equipment uses dBV. Digital meters
use dBFS.
• dBm: The m stands for milliwatt (mW), which is a unit for measuring electrical power.
(Power is different from electrical voltage and current, though it is related to both.)
This was the standard used in the early days of telephone technology and remained
the professional audio standard for years.

492

Appendix B Audio Fundamentals

• dBu: This reference level measures voltage instead of power, using a reference level of
0.775 volts. dBu has mostly replaced dBm on professional audio equipment. The u
stands for unloaded, because the electrical load in an audio circuit is no longer as
relevant as it was in the early days of audio equipment.
• dBV: This also uses a reference voltage like dBu, but in this case the reference level is
1 volt, which is more convenient than 0.775 volts in dBu. dBV is often used on consumer
and semiprofessional devices.
• dBFS: This scale is very different from the others because it is used for measuring digital
audio levels. FS stands for full-scale, which is used because, unlike analog audio signals
that have an optimum signal voltage, the entire range of digital values is equally
acceptable when using digital audio. 0 dBFS is the highest-possible digital audio signal
you can record without distortion. Unlike analog audio scales like dBV and dBu, there
is no headroom past 0 dBFS.

Signal-to-Noise Ratio
Every electrical system produces a certain amount of low-level electrical activity called
noise. The noise floor is the level of noise inherent in a system. It is nearly impossible to
eliminate all the noise in an electrical system, but you don’t have to worry about the noise
if you record your signals significantly higher than the noise floor. If you record audio too
low, you raise the volume to hear it, which also raises the volume of the noise floor,
causing a noticeable hiss.
The more a signal is amplified, the louder the noise becomes. Therefore, it is important
to record most audio around the nominal (ideal) level of the device, which is labeled 0 dB
on an analog audio meter.
The signal-to-noise ratio, typically measured in dB, is the difference between the nominal
recording level and the noise floor of the device. For example, the signal-to-noise ratio
of an analog tape deck may be 60 dB, which means the inherent noise in the system is
60 dB lower than the ideal recording level.

Headroom and Distortion
If an audio signal is too strong, it will overdrive the audio circuit, causing the shape of the
signal to distort. In analog equipment, distortion increases gradually the more the audio
signal overdrives the circuit. For some audio recordings, this kind of distortion can add a
unique “warmth” to the recording that is difficult to achieve with digital equipment.
However, for audio post-production, the goal is to keep the signal clean and undistorted.

Appendix B Audio Fundamentals

493

0 dB on an analog meter refers to the ideal recording level, but there is some allowance
for stronger signals before distortion occurs. This safety margin is known as headroom,
meaning that the signal can occasionally go higher than the ideal recording level without
distorting. Having headroom is critical when recording, especially when the audio level
is very dynamic and unpredictable. Even though you can adjust the recording level while
you record, you can’t always anticipate quick, loud sounds. The extra headroom above
0 dB on the meter is there in case the audio abruptly becomes loud.

Dynamic Range and Compression
Dynamic range is the difference between the quietest and loudest sound in your mix. A
mix that contains quiet whispers and loud screams has a large dynamic range. A recording
of a constant drone such as an air conditioner or steady freeway traffic has very little
amplitude variation, so it has a small dynamic range.
You can actually see the dynamic range of an audio clip by looking at its waveform. For
example, two waveforms are shown below. The top one is a section from a well-known
piece of classical music. The bottom one is from a piece of electronic music. From the
widely varied shape of the waveform, you can tell that the classical piece has the greater
dynamic range.

Waveform from a
well-known classical
piece
Waveform from an
excerpt of electronic
music

Notice that the loud and soft parts of the classical piece vary more frequently, as compared
to the fairly consistent levels of the electronic music. The long, drawn-out part of the
waveform at the left end of the top piece is not silence—it’s actually a long, low section
of the music.
Dynamic sound has drastic volume changes. Sound can be made less dynamic by reducing,
or compressing, the loudest parts of the signal to be closer to the quiet parts. Compression
is a useful technique because it makes the sounds in your mix more equal. For example,
a train pulling into the station, a man talking, and the quiet sounds of a cricket-filled
evening are, in absolute terms, very different volumes. Because televisions and film
theaters must compete with ambient noise in the real world, it is important that the quiet
sounds are not lost.

494

Appendix B Audio Fundamentals

The goal is to make the quiet sounds (in this case, the crickets) louder so they can compete
with the ambient noise in the listening environment. One approach to making the crickets
louder is to simply raise the level of the entire soundtrack, but when you increase the
level of the quiet sounds, the loud sounds (such as the train) get too loud and distort.
Instead of raising the entire volume of your mix, you can compress the loud sounds so
they are closer to the quiet sounds. Once the loud sounds are quieter (and the quiet
sounds remain the same level), you can raise the overall level of the mix, bringing up the
quiet sounds without distorting the loud sounds.
When used sparingly, compression can help you bring up the overall level of your mix
to compete with noise in the listening environment. However, if you compress a signal
too far, it sounds very unnatural. For example, reducing the sound of an airplane jet
engine to the sound of a quiet forest at night and then raising the volume to maximum
would cause the noise in the forest to be amplified immensely.
Different media and genres use different levels of compression. Radio and television
commercials use compression to achieve a consistent wall of sound. If the radio or
television becomes too quiet, the audience may change the channel—a risk advertisers
and broadcasters don’t want to take. Films in theaters have a slightly wider dynamic range
because the ambient noise level of the theater is lower, so quiet sounds can remain quiet.

Stereo Audio
The human ear hears sounds in stereo, and the brain uses the subtle differences in sounds
entering the left and right ears to locate sounds in the environment. To re-create this
sonic experience, stereo recordings require two audio channels throughout the recording
and playback process. The microphones must be properly positioned to accurately capture
a stereo image, and speakers must also be spaced properly to re-create a stereo image
accurately.
If any part of the audio reproduction pathway eliminates one of the audio channels, the
stereo image will most likely be compromised. For example, if your playback system has
a CD player (two audio channels) connected to only one speaker, you will not hear the
intended stereo image.
Important: All stereo recordings require two channels, but two-channel recordings are
not necessarily stereo. For example, if you use a single-capsule microphone to record the
same signal on two tracks, you are not making a stereo recording.
Identifying Two-Channel Mono Recordings
When you are working with two-channel audio, it is important to be able to distinguish
between true stereo recordings and two tracks used to record two independent mono
channels. These are called dual mono recordings.

Appendix B Audio Fundamentals

495

Examples of dual mono recordings include:
• Two independent microphones used to record two independent sounds, such as two
different actors speaking. These microphones independently follow each actor’s voice
and are never positioned in a stereo left-right configuration. In this case, the intent is
not a stereo recording but two discrete mono channels of synchronized sound.
• Two channels with exactly the same signal. This is no different than a mono recording,
because both channels contain exactly the same information. Production audio is
sometimes recorded this way, with slightly different gain settings on each channel.
This way, if one channel distorts, you have a safety channel recorded at a lower level.
• Two completely unrelated sounds, such as dialogue on track 1 and a timecode audio
signal on track 2, or music on channel 1 and sound effects on channel 2. Conceptually,
this is not much different than recording two discrete dialogue tracks in the example
above.
The important point to remember is that if you have a two-track recording system, each
track can be used to record anything you want. If you use the two tracks to record properly
positioned left and right microphones, you can make a stereo recording. Otherwise, you
are simply making a two-channel mono recording.
Identifying Stereo Recordings
When you are trying to decide how to work with an audio clip, you need to know whether
a two-channel recording was intended to be stereo or not. Usually, the person recording
production sound will have labeled the tapes or audio files to indicate whether they were
recorded as stereo recordings or dual-channel mono recordings. However, things don’t
always go as planned, and tapes aren’t always labeled as thoroughly as they should be.
As an editor, it’s important to learn how to differentiate between the two.
Here are some tips for distinguishing stereo from dual mono recordings:
• Stereo recordings must have two independent tracks. If you have a tape with only one
track of audio, or a one-channel audio file, your audio is mono, not stereo.
Note: It is possible that a one-channel audio file is one half of a stereo pair. These are
known as split stereo files, because the left and right channels are contained in
independent files. Usually, these files are labeled accordingly: AudioFile.L and AudioFile.R
are two audio files that make up the left and right channels of a stereo sound.
• Almost all music, especially commercially available music, is mixed in stereo.
• Listen to a clip using two (stereo) speakers. If each side sounds subtly different, it is
probably stereo. If each side sounds absolutely the same, it may be a mono recording.
If each side is completely unrelated, it is a dual mono recording.

496

Appendix B Audio Fundamentals

Interleaved Versus Split Stereo Audio Files
Digital audio can send a stereo signal within a single stream by interleaving the digital
samples during transmission and deinterleaving them on playback. The way the signal
is stored is unimportant as long as the samples are properly split to left and right channels
during playback. With analog technology, the signal is not nearly as flexible.
Split stereo files are two independent audio files that work together, one for the left
channel (AudioFile.L) and one for the right channel (AudioFile.R). This mirrors the traditional
analog method of one track per channel (or in this case, one file per channel).

Digital Audio
Digital audio recording works by recording, or sampling, an electronic audio signal at
regular intervals (of time). An analog-to-digital (A/D) converter measures and stores each
sample as a numerical value that represents the audio amplitude at that particular moment.
Converting the amplitude of each sample to a binary number is called quantization. The
number of bits used for quantization is referred to as bit depth. Sample rate and bit depth
are two of the most important factors when determining the quality of a digital audio
system.

Sample Rate
The sample rate is the number of times an analog signal is measured—or sampled—per
second. You can also think of the sample rate as the number of electronic snapshots
made of the sound wave per second. Higher sample rates result in higher sound quality
because the analog waveform is more closely approximated by the discrete samples.
Which sample rate you choose to work with depends on the source material you’re
working with, the capabilities of your audio interface, and the final destination of your
audio.
For years, the digital audio sample rate standards have been 44,100 Hz (44.1 kHz) and
48 kHz. However, as technology improves, 96 kHz and even 192 kHz sample rates are
becoming common.
Audio sample rates

When used

8 kHz-22.225 kHz

These lower sample rates are used strictly for multimedia files.

32 kHz

32 kHz is generally used with 12-bit audio on DV.

44.1 kHz

This sample rate is used for music CDs and some DAT recorders.

48 kHz

Almost all digital video formats use this sample rate.

88.2 kHz

A multiple of 44.1 kHz. This is useful for high-resolution audio that
needs to be compatible with 44.1 kHz. For example, if you eventually
plan to burn an audio CD, this sample rate is a good choice.

96 kHz

A multiple of 48 kHz. This is becoming the professional standard
for audio post-production and music recording.

Appendix B Audio Fundamentals

497

Audio sample rates

When used

192 kHz

A multiple of 48 and 96 kHz, this is a very high-resolution sample
rate used mostly for professional music recording and mastering.

Bit Depth
Unlike analog signals, which have an infinite range of volume levels, digital audio samples
use binary numbers (bits) to represent the strength of each audio sample. The accuracy
of each sample is determined by its bit depth. Higher bit depths mean your audio signal
is more accurately represented when it is sampled. Most digital audio systems use a
minimum of 16 bits per sample, which can represent 65,536 possible levels (24-bit samples
can represent over 16 million possible levels).
To better understand bit depth, think of each digital audio sample as a ladder with equally
spaced rungs that climb from silence to full volume. Each rung on the ladder is a possible
volume that a sample can represent, while the spaces between rungs are in between
volumes that a sample cannot represent.
When a sample is made, the audio level of the analog signal often falls in the spaces
between rungs. In this case, the sample must be rounded to the nearest rung. The bit
depth of a digital audio sample determines how closely the rungs are spaced. The more
rungs available (or, the less space between rungs), the more precisely the original signal
can be represented.
Quantization errors occur when a digital audio sample does not exactly match the analog
signal strength it is supposed to represent (in other words, the digital audio sample is
slightly higher or lower than the analog signal). Quantization errors are also called rounding
errors because imprecise numbers represent the original analog audio. For example,
suppose an audio signal is exactly 1.15 volts, but the analog-to-digital converter rounds
this to 1 volt because this is the closest bit value available. This rounding error causes
noise in your digital audio signal. While quantization noise may be imperceptible, it can
potentially be exacerbated by further digital processing. Always try to use the highest
bit depth possible to avoid quantization errors.
The diagram on the far right shows the highest bit depth, and therefore the audio samples
more accurately reflect the shape of the original analog audio signal.

498

Appendix B Audio Fundamentals

Audio sample

For example, a 1-bit system (a ladder with only two rungs) can represent either silence
or full volume, and nothing in between. Any audio sample that falls between these rungs
must be rounded to full volume or silence. Such a system would have absolutely no
subtlety, rounding smooth analog signals to a square-shaped waveform.

Sine

When the number of bits per sample is increased, each sample can more accurately
represent the audio signal.

1-bit

2-bit

4-bit

16-bit

To avoid rounding errors, you should always use the highest bit depth your equipment
supports. Most digital video devices use 16- or 20-bit audio, so you may be limited to
one of these bit depths. However, professional audio recording devices usually support
24-bit audio, which has become the industry standard.
Bit depth

When used

32-bit floating point

This allows audio calculations, such as fader levels and effects
processing, to be performed at very high resolution with a minimum
of error, which preserves the quality of your digital audio.

24-bit

This has become the audio industry standard for most audio
recording formats. Most professional audio interfaces and computer
audio editing systems can record with 24-bit precision.

20-bit

Used in some video formats such as Digital Betacam and audio
formats such as ADAT Type II.

16-bit

DAT recorders, Tascam DA-88 and ADAT Type I multitracks, and
audio CDs all use 16-bit samples. Many digital video formats, such
as DV, use 16-bit audio.1

8-bit

In the past, 8-bit audio was often used for CD-ROM and web video.
Today, 16-bit audio is usually preferred, but available bandwidth
and compatibility with your target user’s system are your chief
considerations when outputting audio for multimedia use.

1 Many consumer DV camcorders allow you to record four audio channels using 12-bit mode, but this is not
recommended for professional work.

Video Interfaces
Final Cut Studio allows you to use a wide variety of video interfaces for capture and output.
The following sections show examples of the most common types of video interfaces
available.

FireWire for DV
You can use the built-in FireWire port on your computer to capture and output to almost
any DV device, including DV, DVCAM, DVCPRO, DVCPRO 50, and DVCPRO HD devices.

FireWire for Uncompressed Digital Video
Interfaces such as the AJA Io connect to your computer via FireWire. However, instead
of transferring compressed DV signals, the AJA Io transfers an uncompressed component
4:2:2 signal via FireWire. The AJA Io has a wide range of digital and analog connectors,
as well as RS-422 device control.

Important: Although this type of video interface uses FireWire, it is not used to connect
DV devices. If you want to capture or output DV video, you can connect your DV device
directly to the FireWire port on your computer.

PCI Express Video Interface Card
If you are using professional analog or digital formats (either standard definition or high
definition) without native FireWire connectivity, you need to purchase and install a PCI
Express video interface card to connect your video deck or camcorder to your computer.
Many PCI Express interface cards come with a breakout box where video, audio, and
perhaps even 9-pin remote connectors are located (rather than on the PCI Express card
itself ). Interface cards are also referred to as video cards or capture cards. This is not the
same as the video graphics card used to send signals to your main computer display.

Note: Some broadcast-quality video output devices receive both the video and audio
from a project. When you use a video output device that supports both video and audio
output, Soundtrack Pro automatically routes your audio output to this device to provide
the best possible synchronization of the audio and video.
PCI Express Video Interface Card with Built-in Connectors
PCI Express cards allow you to capture and output video with high data rates, such as
uncompressed standard definition (SD) and high definition (HD) video. PCI Express cards
are necessary for high-end applications such as compositing, online editing, and
uncompressed video editing. Many PCI Express cards have BNC or RCA connectors
mounted directly on the back of the card. In this configuration, you connect your video
equipment directly to the PCI Express card connectors on the back of your computer.

PCI Express Video Interface Card with Breakout Box
Many PCI Express cards aren’t big enough to fit all of the necessary video and audio
connectors. In these situations, a breakout box is connected to the PCI Express card via
a multipin connector on a long cable, and the connectors are accessible on the breakout
box instead of the back of the PCI Express card. A breakout box is also useful because it
allows you to place the connectors somewhere more convenient than the back of your
computer, such as on an equipment rack or a desktop.

Video Signals and Connectors
When you capture and output, the type of video signal you use to connect your equipment
is a critical factor that goes into determining the quality of your video. Video camcorders,
decks, and monitors can use different types of signals, depending on the environment
they are intended for. Consumer equipment usually has limited video signal choices;
professional equipment gives you the greatest range of options.
Here are the most common video signals used on today’s video devices:
• Composite: For more information, see Composite.
• S-Video (Y/C): For more information, see S-Video.

504

Appendix C Working with Professional Video and Audio Equipment

• Component YUV (Y′CBCR): For more information, see Component YUV and Component
RGB.
• Component RGB: For more information, see Component YUV and Component RGB.
• FireWire (IEEE 1394 or i.LINK): For more information, see FireWire 400 and FireWire 800.
• SDI: For more information, see SDI.
• HD-SDI: For more information, see HD-SDI.
• SDTI: For more information, see SDTI.
• HDMI: For more information, see HDMI.
• SCART: For more information, see SCART.

Composite
Composite is the lowest common denominator of video signals. A composite signal runs
all color and brightness information on a single cable, resulting in lower-quality video
compared to the quality of other formats. Nearly all video devices have a composite input
and output. This format uses a single RCA or BNC connector.
In professional editing environments, composite video signals are most commonly used
for troubleshooting, for menu outputs, and for low-quality preview monitoring. For
consumer and home use, composite signals are often used to connect VCRs or DVD
players to televisions.
RCA connector

BNC connector

S-Video
S-Video, also known as Y/C, is a higher-quality video signal used by high-end consumer
video equipment. The image looks sharper and has better color than a composite video
image because S-Video keeps the color and brightness information separate on two
cables. Most low-cost analog-to-digital video interfaces have S-Video as their
highest-quality video connector. Use care when working with S-video connectors; the
four delicate pins can be bent easily.
S-Video connector

Appendix C Working with Professional Video and Audio Equipment

505

Component YUV and Component RGB
Professional video equipment, such as Betacam SP decks, has component YUV (Y′CBCR)
video inputs and outputs. Component YUV separates color and brightness information
into three signals, which keeps the color quality more accurate than that of other systems.
Component YUV is as good as analog video gets. High-end consumer devices, such as
DVD players and televisions, have increasingly begun to support component YUV.
Note: Another form of component video, component RGB, is not as widespread on
professional equipment as component YUV.
Both component YUV and RGB signals use from three to five connectors. You can use
three BNC connectors, plus a fourth (typically labeled “genlock” or “house sync”) to send
a timing signal. Sync can also be embedded in the Y or G part of the signal (using three
connectors), a separate composite signal on a fourth connector, or separate H and V drive
signals (using five connectors). See your equipment’s documentation for more information.

FireWire 400
FireWire 400, also called IEEE 1394a or i.LINK, is the consumer and professional standard
for formats such as DV, DVCAM, DVCPRO, DVCPRO 50, DVCPRO HD, and HDV. FireWire is
an inexpensive and easy way to capture and output high-quality digital video using a
variety of camcorders and decks and is capable of data rates as high as 400 Mbps. Standard
FireWire cables can be up to 4.5 meters long.
There are two kinds of FireWire connectors: a 4-pin connector (typically found on video
equipment such as camcorders or decks) and a 6-pin connector (used for computer
equipment). However, some newer video equipment uses the 6-pin connector, and some
video interfaces use the 4-pin connector. See your equipment’s documentation for more
information.

FireWire 800
FireWire 800, also called IEEE 1394b, is the next generation of FireWire after IEEE 1394a, a
higher-bandwidth version capable of data transfer speeds of up to 800 Mbps. FireWire
800 is also capable of supporting cable distances of up to 100 meters.
In addition to the standard 9-pin-to-9-pin FireWire 800 cables, 9-pin-to-4-pin and
9-pin-to-6-pin FireWire 400 to FireWire 800 cables are also available to connect older
devices to a FireWire 800 interface.

FireWire 800 (9-pin)

Note: FireWire 800 is commonly used to connect hard disks and other data peripherals
to your computer, but this connector is rarely used to connect video devices.

SDI
Serial Digital Interface (SDI) is the standard for high-end, uncompressed digital video
formats such as D1, D5, and Digital Betacam. If you want to capture digital video from
these formats at the highest possible quality, you need a video interface with an SDI input
and output, as well as a high-performance disk array (a set of disk drives grouped together
to read and write in parallel), to accommodate the high data rates you’ll work with. Many
devices can send both video and audio data through a single SDI connection.
BNC connector

HD-SDI
High Definition Serial Digital Interface (HD-SDI) is a higher-bandwidth version of SDI
designed for the extremely high data rates required by uncompressed HD video. Like
SDI, HD-SDI is capable of sending both video and audio through a single connection. The
following decks have HD-SDI interfaces: DVCPRO HD, D-5 HD, and HDCAM decks.
Some devices provide even higher data rates by pairing two HD-SDI channels together
(known as dual-link HD-SDI). Uncompressed HD RGB video and other digital cinema
formats can be transmitted using dual-link HD-SDI.

Appendix C Working with Professional Video and Audio Equipment

507

SDTI
Serial Digital Transport Interface (SDTI) is based on SDI, allowing native video formats to
be sent in real time within an SDI video stream. SDTI does not define a specific video
signal format but instead uses the structure of SDI to carry any kind of data. This allows
video facilities to use their existing SDI patchbays and routers to transfer other native
video formats, or transfer any kind of data. For example, some DV decks can transfer DV
via SDTI, which means native DV can be transferred long distances over existing coaxial
cable instead of the usual FireWire connection. Other formats, such as HDCAM and MPEG,
can also be transferred via packets within an SDTI transport stream.

HDMI
High-Definition Multimedia Interface (HDMI) supports both digital television and computer
signals and can also include multiple digital audio channels. HDMI devices are compatible
with single-link digital DVD signals via an adapter, although no audio or additional
metadata can be included. Many HD display devices and digital television set-top boxes
include HDMI connectors.
HDMI connector

SCART
Consumer PAL equipment sometimes has a special connector called a SCART connector.
A SCART connector has multiple pins that run composite, component RGB, and stereo
audio in one bundle. SCART input or output can be broken up into individual connections
using special adapters available from video and home electronics stores.

Setting Up an Audio Interface
By default, Soundtrack Pro uses one of the built-in audio interfaces included with your
Macintosh computer, such as a stereo headphone jack or a stereo speaker output. If you
need to capture audio from a professional device, you may need a separate third-party
interface. You can connect a third-party audio interface to your computer, and then
connect microphones and musical instruments to the audio interface for recording. You
can also connect output devices, such as monitors or speakers, a mixer, or an amplifier
to the third-party audio interface.

Built-in Audio Interfaces
The following audio interfaces are included with your Macintosh computer (though some
computer models may not include all interfaces).

508

Appendix C Working with Professional Video and Audio Equipment

Built-in Analog Audio
You can capture and output audio using the built-in audio ports on your computer. The
built-in audio interface on your computer usually uses a stereo miniplug connector. If
necessary, you can buy an adapter to connect the miniplug connector to two stereo RCA
or 1/4" tip-ring-sleeve (TRS) connectors, which can then be connected to your video or
audio device.

Analog audio or video device

For basic mixing, you can connect the built-in audio output on your computer to a pair
of external speakers. This gives you two output channels, which can be configured for
dual mono or stereo playback.
Built-in S/PDIF Digital Audio
Some computers have built-in S/PDIF optical digital ports (sometimes called TOSLINK)
that you can connect to some CD players, DAT recorders, and other digital audio devices.

DV FireWire
If your post-production project uses a DV codec, you can output audio via the FireWire
port on your computer. This allows you to use a DV deck, DV camcorder, or DVtoanalog
converter as an audio interface. In this case, you connect your FireWire cable to your DV
device and then connect the audio outputs of the DV device to external speakers or a
television monitor.

Appendix C Working with Professional Video and Audio Equipment

509

Choosing a Third-Party Audio Interface
Before you purchase a separate audio interface, consider that most third-party video
interfaces may have enough audio connectors to meet your requirements. You should
consider a separate audio interface when:
• You are trying to capture or output more audio channels than your built-in audio
interface or third-party video interface supports.
• You need to capture or output in a format not supported by your existing interfaces
(for example, if you need to capture audio at a sample rate of 96 kHz but your video
interface only supports a sample rate of 48 kHz).
Benefits of a Third-Party Audio Interface
Third-party audio interfaces can provide many more features than your computer’s built-in
interfaces, such as:
• More than two audio channels—eight channels is common, but some interfaces have
24 or more input and output channels
• Professional connectors such as XLR or 1/4" TRS
• High-quality analog-to-digital and digital-to-analog converters supporting sample rates
as high as 192 kHz and 24 bits per sample
• Support for analog and digital audio formats
• Stable, “jitter-free” digital audio clocks
Tips for Selecting a Third-Party Audio Interface
When you select an audio interface, make sure it has the following:
• Connectors that match your audio equipment, such as XLR, 1/4" TRS, RCA, or TOSLINK
• Support for audio signal formats that your audio equipment uses, such as AES/EBU,
S/PDIF, or ADAT Lightpipe
• Enough audio inputs and outputs to connect your equipment
• Sample rate and bit depth at least as high as your audio equipment. For example, if
you have an audio device with a sample rate of 96 kHz and 24 bits, your audio interface
should at least match this. Soundtrack Pro supports input from digital audio interfaces
up to a maximum sample rate of 96 kHz and a maximum bit depth of 24 bits. If you
connect an interface that uses sample rates or bit depths outside the range supported
by Soundtrack Pro, an alert message appears, telling you that data from the audio
interface is not compatible with the application.
• Mac OS X compatibility. When choosing an audio interface, check the manufacturer’s
specifications to make sure the interface is compatible with Mac OS X.
• Up-to-date driver software, if needed. If the device requires a driver, make sure an
up-to-date driver is included with the device, or is available from the manufacturer.

510

Appendix C Working with Professional Video and Audio Equipment

Important: If you are considering purchasing an interface, make sure it supports Mac OS X
Core Audio. Soundtrack Pro supports any audio interface that is compatible with Mac OS X
Core Audio.
All digital audio interfaces can be susceptible to latency, a noticeable delay between the
time the audio signal is produced and the time you hear it. When connecting an audio
interface, you should connect the interface directly to the computer, rather than
connecting it through a hub or daisy-chaining it through another device. Connecting an
audio interface through a hub or an intermediary device can cause an unacceptable
amount of latency, particularly with slower protocols such as USB.

FireWire for Digital Audio
FireWire is a professional and consumer standard for both audio and video equipment.
The combination of fast data-transfer rates, high storage capacities, and plug-and-play
connection makes FireWire an attractive choice for working with digital audio files. FireWire
is included on most current Macintosh computers, and a number of FireWire audio
interfaces are available. These third-party interfaces are not DV devices, but merely devices
that use FireWire as a means of transferring digital audio data. FireWire interfaces are
more convenient to switch between computers than PCI Express cards, and they can be
used with both desktop and portable computers. A FireWire interface typically supports
ten or more inputs, and at least eight outputs.

Important: Although a FireWire bus supports a very high data rate, connecting too many
devices, such as a DV video device, a FireWire hard disk, and a FireWire audio interface,
could potentially exceed the bus speed, resulting in audio with missing samples.

USB Audio Interfaces
There are a wide variety of USB audio interfaces available. USB supports plug-and-play
operation and the ability to connect several devices in sequence (daisy-chaining). USB is
included on all current Macintosh computers.

Most USB audio interfaces support two or four audio channels at one time. USB audio
interfaces vary in quality considerably, so take some time to research them before you
purchase one. The connectors on USB interfaces vary; some interfaces have RCA connectors
and others have both XLR and 1/4" TRS connectors. Very inexpensive USB audio interfaces
may only have a stereo miniplug.

Analog or digital VTR

Make sure you don’t exceed the total bandwidth of the USB bus. USB 1.1 has a fairly low
data rate, so be careful not to add too many USB items to the bus. Ideally, USB audio
interfaces are always directly connected to your computer, not connected via a hub or
to the computer’s display, keyboard, or another peripheral. If you are having audio
problems with a USB interface connected to a hub, try removing USB devices and
eliminating the hub from the connection.
USB 2.0 audio interfaces are also available. Because USB 2.0 devices can handle high data
rates (similar to FireWire 400), you can treat them similarly to FireWire audio interfaces
(see FireWire for Digital Audio).

512

Appendix C Working with Professional Video and Audio Equipment

PCI Express Audio Interface Cards
Peripheral Connect Interface (PCI) Express interfaces, unlike FireWire and USB interfaces,
require that you install a dedicated sound card in your computer. Of all the audio interfaces,
PCI Express audio interfaces provide the maximum transfer speed and can support many
channels with high sample rates. Many PCI Express audio interface cards come with a
separate breakout box where the audio input and output connectors are located.

PCI Express Audio Interface Card with Built-in Connectors
Some PCI Express audio interface cards have audio connectors attached directly to the
card. Because there is limited space on a PCI Express card to mount audio connectors,
RCA connectors are typically used.

PCI Express Audio Interface Card with Breakout Box
The majority of PCI Express audio interface cards have a breakout box with a large number
of XLR or 1/4" TRS connectors. The breakout box is attached to the PCI Express card via
a long cable with a multipin connector. The long cable allows you to place the breakout
box in a convenient location, so you can easily connect and disconnect your video and
audio devices without going behind your computer.

Audio Connectors, Cables, and Signal Formats
Different audio connectors and cables are suited for different purposes. They are available
for professional and consumer audio equipment, at a range of prices and levels of quality.
Audio connectors are often indicative of the kind of signal they transmit. However, there
are enough exceptions that it’s important to know what kind of audio signal you are
connecting, in addition to the connector type. An important distinction is whether an
audio connector carries a balanced or an unbalanced signal. When connecting
microphones and musical instruments to an audio interface or a mixer, make sure the
interface has the proper input jacks for the type of connectors and cables you plan to
use.

Analog Audio Connectors, Cables, and Signal Formats
The following is a cross-section of available industry-standard analog audio connectors,
cables, and signal formats.
1/8" Mini Connectors
These are very small, unbalanced audio connectors. Many computers have 1/8" mini
inputs and outputs at -10 dBV line level, and many portable audio devices such as CD
players, iPod digital music players, and MP3 players use these connectors for headphone
outputs. Portable MiniDisc and DAT recorders often use 1/8" mini connectors for
connecting microphones.
Mono miniplug connector

Stereo miniplug connector

Note: Some Macintosh computers and portable audio recorders also use a connector
that combines both a stereo miniplug and a 1/8" optical digital connection (see the
information about S/PDIF in Digital Audio Connectors, Cables, and Signal Formats) in a
single jack.
RCA Connectors
Most consumer equipment uses RCA connectors, which are unbalanced connectors that
usually handle –10 dbV (consumer) line levels. RCA connectors are used on consumer
audio equipment such as home stereo systems and videocassette recorders.
RCA connector

1/4" Audio Connectors
1/4" connectors (sometimes called phone plugs) are used on a wide variety of professional
and consumer musical equipment, including musical instruments and amplifiers, speakers,
and external effects devices.

514

Appendix C Working with Professional Video and Audio Equipment

1/4" Tip-Sleeve Connectors
1/4" tip-sleeve (TS) connectors with a tip and a sleeve are unbalanced connectors often
used for musical instruments like electric guitars, keyboards, amplifiers, and so on.
1/4" tip-sleeve (TS) connector

1/4" Tip-Ring-Sleeve Connectors
Professional equipment often uses 1/4" tip-ring-sleeve (TRS) audio connectors with +4
dBu line level. 1/4" TRS connectors connect to three wires in an audio cable—hot, neutral,
and ground—and usually carry a balanced audio signal. In some situations, the three
wires may be used to send left and right (stereo) signals, making the signals unbalanced.
1/4" tip-ring-sleeve (TRS) connector

Note: Tip-sleeve and tip-ring-sleeve connectors look almost identical. Some audio devices
(especially mixers) accept a TS connector in a TRS jack, but you should always check the
equipment documentation to be sure. Remember that most 1/4" TS connectors connect
to –10 dBV line level equipment, whereas 1/4" TRS connectors usually expect a +4 dBu
line level.
XLR Connectors
These are the most common professional audio connectors. They almost always carry a
balanced signal. Many cables use an XLR connector on one end and a 1/4" TRS connector
on the other. The signal may be microphone level (when using a microphone) or +4
dBu/dBm (professional) line level.
XLR connector

Digital Audio Connectors, Cables, and Signal Formats
Although digital audio signals are completely different from analog signals, the same
connectors are often used for convenience. For example, an XLR connector can be used
to carry an analog audio signal or an AES/EBU digital audio signal. The following is a
cross-section of available industry-standard digital audio connectors, cables, and signal
formats.
S/PDIF
Sony/Philips Digital Interface Format (S/PDIF) is a consumer-level variation of the AES/EBU
digital audio protocol. S/PDIF audio data can be transmitted several ways, including:
• Via coaxial cables with an RCA connector
• Via optical TOSLINK

Appendix C Working with Professional Video and Audio Equipment

515

Connectors for S/PDIF signals are found on most consumer digital equipment, such as
DAT recorders, CD players, DVD players, MiniDisc equipment, and some audio interfaces.
S/PIDF optical digital connector

TOSLINK Optical and ADAT Lightpipe
TOSLINK is a connector for optical digital signals. TOSLINK is used for several digital signal
formats, although most devices support only one of these formats:
• S/PDIF (stereo digital)
• AC-3 and DTS (5.1-channel surround)
• ADAT Lightpipe (an 8-channel digital signal)
Some Macintosh computers have a single interface that combines a TOSLINK connector
with an analog stereo miniplug.
TOSLINK connector

ADAT Lightpipe is an eight-channel digital audio format developed by Alesis. This signal
format uses TOSLINK optical connectors. Eight channels are supported at sample rates
of 44.1 and 48 kHz using 24 bits per sample. Higher sample rates are available by pairing
channels (this format is sometimes called sample multiplexing, or S/MUX). For example, a
sample rate of 192 kHz is possible, but the number of channels is reduced to two. However,
not all equipment supports channel pairing and increased sample rates.
AES/EBU
The AES/EBU (Audio Engineering Society/European Broadcasting Union) standard for
transferring digital audio typically uses XLR connectors in professional studio environments.
The data protocol is essentially identical to S/PDIF.
XLR connector

516

Appendix C Working with Professional Video and Audio Equipment

TDIF Connectors
Tascam Digital Interface (TDIF) is a signal format for transferring digital audio between
Tascam digital multitrack recorders or digital mixers. Connections are made via a 25-pin
D-subminiature connector and data is carried on shielded cable. Eight channels are
supported at sample rates of 44.1 and 48 kHz using 24 bits per sample. Higher sample
rates are available by pairing channels. The TDIF standard is currently one of two major
formats (the other being ADAT optical) widely used in professional products for digital
transfer of more than two tracks of audio simultaneously using only one cable.

TDIF connector

About Microphone, Instrument, and Line Level
Audio equipment can output line level at –10 dBV (consumer level), +4 dBm/dBu
(professional level), or microphone level, which is around 50 or 60 dB less than line level.
When you use a microphone, the level is very low, requiring a preamplifier to raise the
signal to line level before it can be recorded or processed. Most audio mixers, cameras,
and professional portable recording devices have built-in preamplifiers.
Instrument level is between microphone and line level, around –20 dBV or so. Guitars
and keyboards usually output at instrument level.

Signal Differences Between Pro and Consumer Equipment
Professional audio equipment typically uses higher voltage levels than consumer
equipment, and it also measures audio on a different scale.
• Professional analog devices measure audio using dBu (or dBm in older equipment).
0 dB on the audio meter is usually set to +4 dBu, which means optimal levels are 4 dB
greater than 0 dBu (.775 V), or 1.23 V.
• Consumer audio equipment measures audio using dBV. The optimal recording level
on a consumer device is –10 dBV, which means the levels are 10 dB less than 0 dBV
(1 V), or 0.316 V.
Therefore, the difference between an optimal professional level (+4 dBu) and consumer
level (–10 dBV) is not 14 dB, because they are referencing different signals. This is not
necessarily a problem, but you need to be aware of these level differences when
connecting consumer and professional audio equipment together.

Appendix C Working with Professional Video and Audio Equipment

517

About Balanced Audio Signals
Audio cables can be either balanced or unbalanced, depending on their intended use.
For long cable runs, especially when using relatively low microphone levels, a three-wire
balanced audio circuit reduces noise. Balanced audio cables use the principle of phase
cancelation to eliminate noise while maintaining the original audio signal.
A balanced audio cable sends the same audio signal on two wires, but inverts the phase
of one signal by 180 degrees.

Original signal

Inverted signal
(reverse phase)

When noise is introduced into the cable, it is introduced equally to both the original and
the inverted signal.

Noise on line
(affects both signals)

518

Appendix C Working with Professional Video and Audio Equipment

When the signal arrives at its destination, the inverted signal is put back in phase and
both signals are combined. This puts the original and inverted signals back in phase, but
it causes the noise signals on each line to be out of phase.

Inverted signal
(inverted again)

Now, both audio signals are in phase, but the noise is inverted, causing the noise to be
canceled. At the same time, the original signal gets a little stronger because it is sent on
two wires and combined. This helps compensate for the reduction in signal strength that
occurs naturally on a long cable run.

Combined signals
(noise eliminated)

Any noise introduced into the cable across its long run is almost completely eliminated
by this process.
Note: Unbalanced cables have no way of eliminating noise and are therefore not as robust
for long-distance cable runs, microphone signals, and other professional applications.

Tips for Choosing Speakers and an Amplifier
Professional audio engineers have to be able to trust the sound coming from their
speakers. When you mix your audio, you need audio monitors that can handle the full
range of audio intensities and frequencies. Ideally, your monitors will have a flat frequency
response from 20 Hz to 20,000 Hz (or 20 kHz). This means that they neither attenuate nor
amplify any frequencies. Flat frequency response is important for critical listening because
the speakers themselves are not “coloring” the sound.
In addition to the speaker quality itself, additional factors affect your audio monitoring
environment:
• Size and materials of the room

Appendix C Working with Professional Video and Audio Equipment

519

• Placement of the speakers within the room, such as distance from walls and angle of
speakers
• Listener position between speakers

Frequency Response and Dynamic Range
Speaker quality varies greatly depending on their purpose as well as their price. For
example, speakers in a portable stereo or television are designed to play audio that has
already been mastered by a mixing engineer. Mastered audio such as audio CD, radio,
television, and movie sound has a compressed dynamic range (meaning levels are fairly
consistent and loud).
Speakers and amplifiers that are designed for mastered audio often intentionally emphasize
certain frequencies, as is done with the bass enhancement feature found on many systems.
This may make an audio CD sound better, but it is not recommended for mixing production
sound because you get a false impression of the audio signal. For example, if your speakers
overemphasize frequencies around 2 kHz, you may compensate during mixing by reducing
the intensity of audio around 2 kHz. If you then play your mix on a different set of speakers
with a flat frequency response, the frequencies around 2 kHz will sound too muffled.

Self-Powered Versus Passive Speakers
Speakers powered by an external amplifier are called passive speakers. When you use
separate amplifiers and passive speakers, a number of factors affect the overall frequency
response and quality of your audio. Instead of using a separate amplifier and speakers, a
simpler option is to use self-powered speakers (speakers with built-in amplifiers). These
have become increasingly popular, especially for studio monitoring and video editing.
Self-powered speakers deliver more consistent performance because both components
are designed to work together and are housed in a single enclosure. For video editing
systems, self-powered speakers are a good, easy-to-use solution. Self-powered speakers
accept line level inputs, so it’s fairly easy to connect them to your audio interface.

520

Appendix C Working with Professional Video and Audio Equipment

Amplifiers and Signal Levels for Unpowered Speakers
Unpowered speakers require signals with higher voltage than consumer and professional
equipment can provide directly. These levels are known as speaker level audio signals,
while audio devices such as tape recorders and audio mixers usually provide line level
signals. An audio amplifier boosts line level signals to speaker levels to properly drive
speakers. Wide-gauge speaker cables that can handle the higher electrical strength of
speaker levels are used to connect the amplifier to speakers.

Connecting Professional Video Devices
Regardless of what format or video interface you use, the same basic steps apply when
you connect a VTR or camcorder to your computer.

Connecting Professional SD Video Devices
If you’re using a format other than DV, such as Betacam SP or Digital Betacam, you need
to install a third-party video interface that supports the proper signal for the format you’re
using. Some video interfaces can digitize analog video input and output (for analog
formats like Betacam SP), while others capture video only if it is already digital. In either
case, the video interface encodes the video information using a codec, which may or may
not apply compression to the video data to make it smaller while stored on disk.
Compression settings used by video interfaces are typically controlled by software and
use a variation of the M-JPEG codec (although the name of the codec itself may not reflect
this).
Unlike DV video devices (which use a single FireWire cable), third-party interfaces send
and receive video, audio, and device control data on separate cables. For remote device
control connections on professional equipment, 9-pin (DB9) connectors are used.

A Recommended System Using a Third-Party Video Interface
To set up a system using a third-party video interface, you need the following equipment:
• Your computer and display
• A non-DV format video device (a camcorder or deck)
• Audio and video cables for your system
• A third-party capture interface installed in or connected to your computer
Note: Some third-party video interfaces have a breakout box connected to the card
with a special cable, which is included.
• A USB-to-serial adapter or internal modem serial port adapter
• An RS-422 video deck control cable
• A blackburst generator, with the appropriate cables to connect it to both your
third-party video interface and your video and audio devices

To connect video and audio outputs from your VTR to your third-party video interface
1 Install a supported third-party PCI Express video interface in your computer or connect
a FireWire or USB video interface.
For detailed information, see the documentation that came with your video interface and
your computer.
2 If you are using a PCI Express card video interface that came with a breakout box, connect
the breakout box to the PCI Express card using the cables provided.
3 Connect the video output of your VTR or camcorder to the video input of your video
interface.
4 Connect the audio outputs of your VTR or camcorder to the audio inputs of your video
or audio interface.
5 Connect the 9-pin remote device control cable to your deck, and to your breakout box
or serial port adapter.
6 To genlock your video interface with your camcorder or deck:
a Connect one of the blackburst generator’s outputs (there should be several) to the
genlock or external sync input on your deck (usually you use a cable with a BNC
connector).
b Connect another of the blackburst generator’s outputs to the genlock or external sync
connector on your video interface.

522

Appendix C Working with Professional Video and Audio Equipment

7 Plug in and turn on your blackburst generator.
8 Turn on your deck.
9 If you’re using Soundtrack Pro or Final Cut Pro to control your camcorder or deck, make
sure that the device control switch on your VTR is set to Remote.
For more information about VTR settings, see the documentation that came with your
VTR and your video interface.
For information about synchronizing Soundtrack Pro to an external video deck or audio
recorder, see Synchronizing Soundtrack Pro to External Timecode.
Note: Some broadcast-quality video output devices receive both the video and audio
from a project. When you use a video output device that supports both video and audio
output, Soundtrack Pro automatically routes your audio output to this device to provide
the best possible synchronization of the audio and video.

Connecting Professional Component Analog Video Devices
The most prevalent component analog video format still in use today is Betacam SP. It is
an SD video format, but because it is analog, your video interface must have
analog-to-digital converters to digitize the analog signal before encoding it and writing
a digital media file to the computer hard disk. Unlike digital capture interfaces,
analog-to-digital interfaces often allow you to adjust luma and chroma levels (using
controls in the Final Cut Pro Log and Capture window) when you digitize.
The steps for connecting an analog VTR to a video interface are essentially the same as
for digital SD and HD devices. The main difference is that you need to make three physical
connections, one for each of the three analog video components: Y, R-Y, and B-Y (also
called YUV or Y′CBCR, depending on the country and the specifics of the format). For more
information, see the Final Cut Pro User Manual. To connect equipment, see Connecting
Professional SD Video Devices.

Connecting Consumer Analog Video Devices
If you want to digitize video from an analog consumer format, such as VHS or 8 mm video,
you need a video interface that has an analog composite video input. Also, older consumer
decks rarely support remote device control, which means you can’t remotely control the
deck or capture timecode from these formats. If you need the ability to recapture the
video accurately using timecode, it’s often easiest to dub (copy) the video to a digital
format like DV, or a professional format you are using for your project.
There are fairly inexpensive capture interfaces that can accept an analog composite input
and convert it to a DV video signal transferred via FireWire. Some more expensive interfaces
may also accept an analog component input.

Appendix C Working with Professional Video and Audio Equipment

523

Connecting Non-DV Devices to a DV Converter
You can use a DV converter to convert a device in a non-DV format, such as Betacam SP
or Digital Betacam, to DV. This allows you to capture footage using the built-in FireWire
port on your computer. However, unlike a complete DV FireWire setup, this kind of deck
still requires serial (RS-422 or RS-232) remote device control.
This kind of setup is used mainly for low-resolution capture and offline editing. Because
Final Cut Pro can edit DV video natively, you can capture your video as if it were DV
footage, edit at DV resolution, and then recapture only the necessary media files for your
finished movie at full resolution using one of the third-party video interface solutions
described earlier.
Important: If you plan to recapture footage later, make sure timecode is captured
accurately.

A Recommended Non-DV-to-DV System Using Serial Device Control
You need the following equipment:
• Your computer and display
• A non-DV format playback device, such as a Betacam SP or Digital Betacam deck
• An analog-to-DV or digital SDI-to-DV converter
Note: Some DV camcorders and VTRs can also act as an analog-to-DV converter.
• A 4-to-6-pin FireWire cable, available at an electronics store or an Apple Authorized
Reseller
• A USB-to-serial adapter or internal modem serial port adapter
• An RS-422 video deck control cable

the FireWire port on your computer.
2 Connect the 4-pin connector on the FireWire cable to the DV converter.
3 Connect the video output of your VTR to the video input of the DV converter.
4 Connect the audio output of your VTR to the audio input of the DV converter.
Note: The DV converter mentioned above could possibly be a DV VTR that can convert
analog video and audio input to DV FireWire. Some decks need to be in record mode to
allow this conversion. Other decks may not support this.
5 Connect the remote device control.

Connecting Professional Audio Devices
The steps for connecting audio playback and recording devices are similar to the steps
for connecting professional video devices. (For information on connecting professional
video devices, see Connecting Professional Video Devices.) Many professional audio-only
devices such as DAT recorders and Tascam DA-88/DA-98 multitracks also support remote
device control and audio insert editing.
If you plan to capture footage using separate video and audio interfaces, you may need
to set up additional synchronization between your audio device and audio interface. For
more information, see Synchronizing Equipment with a Blackburst Generator as well as
the documentation that came with your audio interface.

Connecting Professional Digital Audio Devices
Professional digital audio devices often use balanced XLR connectors. Each XLR carries
two AES/EBU digital audio channels. Connect the digital audio outputs of your video or
audio device to your audio interface (or its breakout box). If your video interface has the
appropriate connectors, you can also connect the audio outputs of your device to the
audio inputs on the video interface.
Note: Professional analog audio devices also use XLR connectors, but the signal is
incompatible with AES/EBU digital audio.

Connecting Consumer Digital Audio Devices
Consumer devices such as CD players, MiniDisc recorders, and some DAT recorders use
either an optical or RCA (coax) connector for S/PDIF digital audio. S/PDIF carries two
channels of digital audio, usually at a sample rate of 44.1 or 48 kHz and a bit depth of
16 bits. Connect the S/PDIF output of your audio device to the S/PDIF input on your audio
or video interface, if available.

Appendix C Working with Professional Video and Audio Equipment

525

Connecting Professional Analog Audio
Professional analog audio devices use balanced XLR or 1/4" TRS connectors for each audio
channel. Most audio interfaces that support multiple audio channels come with a breakout
box that contains all the connectors.

To connect multiple analog audio channels from a VTR or audio device to a multichannel
audio interface
Connect each audio output channel on the VTR or audio device to each audio input
channel on the audio interface or corresponding breakout box, if included.

A Recommended Audio System Using a Third-Party Audio Interface
To set up a system using a third-party audio interface, you need the following equipment:
• Your computer and display
• A device-controllable audio deck, such as a DAT or multitrack deck
• Appropriate analog cables for your system
• An audio interface
Note: Some third-party PCI Express interface cards have a breakout box connected
to the card with a special cable.
• A USB-to-serial adapter or internal modem serial port adapter
• A blackburst generator, with the appropriate cables to connect it to both your
third-party audio interface and your audio deck. (For more information, see
Synchronizing Equipment with a Blackburst Generator.)
• An RS-422 video deck control cable

Synchronizing Equipment with a Blackburst Generator
With most professional editing systems, you capture video, audio, and timecode via
separate cables. It’s important that when you capture, the VTR and the video and audio
interfaces are synchronized via a common video timing signal. If digital audio samples
and video lines and frames are not precisely synchronized, they eventually drift apart
because they are captured at slightly different rates.
Using a common sync source is especially important when you are independently
capturing long segments of video and audio to synchronize together later. If your audio
deck and capture interface are not both receiving the same timing information, the sync
between the audio and video portions of clips might drift over time.
A blackburst generator provides a common timing signal (or clock) to lock together the
timing clocks of all devices in a system. This is sometimes referred to as external sync or
house sync because every device in an entire facility can be timed to this common
reference.

526

Appendix C Working with Professional Video and Audio Equipment

Professional VTRs, camcorders, audio devices, and interfaces often have the ability to
accept sync signals from an external device. These connectors are labeled “genlock” (short
for generator lock), “external sync,” “reference input,” or “reference video.” On some
equipment, the normal composite video input of a device can be used to lock to external
sync.
Important: To synchronize your video or audio devices and interfaces, they must all
accept an external clock source (such as a blackburst generator).
When you genlock a deck and a video or audio capture interface, one output of the
blackburst generator should be connected to the external sync input of the video or
audio deck, and another output should be connected to the external sync input of your
audio interface.

To connect your audio deck outputs to a third-party audio interface for synchronized,
genlocked audio capture
1 Install a supported audio interface card in your computer, or connect a supported audio
interface.
For more information, see the documentation that came with the audio interface and
your computer.
2 If you are using a PCI Express card audio interface that came with a breakout box, connect
the breakout box to the PCI Express card using the included cable.
3 Connect the audio outputs of your audio device to the audio inputs of your audio interface.
4 Connect the remote device control cable.
5 To genlock your audio deck to your audio or video interface:
a Connect one of the blackburst generator’s outputs (there should be several) to the
genlock or external sync input on your audio deck.
b Connect another of the blackburst generator’s outputs to the genlock or external sync
connector on your video or audio capture interface (depending on which one you are
using to capture audio).
For more information, see Synchronizing Equipment with a Blackburst Generator.

6 Plug in and turn on your blackburst generator.
7 If you are using a blackburst generator, choose Final Cut Pro > User Preferences, and in
the General tab of the User Preferences window, make sure that “Sync audio capture to
video source if present” is selected.
8 If you’re using Final Cut Pro to control your audio deck, make sure that the device control
switch on the equipment is set to Remote.
9 Once your deck and video capture interface are genlocked together, you still need to
calibrate the timecode capture offset (found in the Device Control Presets tab in the
Audio/Video Settings window) prior to capture.
For more information about calibrating timecode for capture, see the Final Cut Pro
User Manual.

Synchronizing Soundtrack Pro to External Timecode
There may be times when you will wish to synchronize Soundtrack Pro to an external
video deck or audio recorder. Soundtrack Pro can “chase” (synchronize to) timecode sent
by an external video deck or other LTC sources.
Note: This is not the same thing as device control, which allows you to remotely control
a video or audio device for capturing and output. See the Final Cut Pro User Manual for
information on device control.
There are two types of signal involved in this process. LTC (Linear Time Code) is an audio
signal sent by a video deck or audio recorder. This signal can’t be read directly by the
computer; it must be converted to MIDI Time Code (MTC) first. MTC can send via USB to
the computer, and via MIDI cables for distribution to other connected MIDI compatible
devices.
You will need the following equipment to synchronize Soundtrack Pro to external
timecode:
• A video deck or audio recorder capable of sending LTC time code
• A device capable of converting LTC to MTC, such as the MotU MIDI Timepiece AV or
Emagic Unitor 8 MKII
• An RCA-to-1/4-inch audio cable, or a 1/4-inch-to-1/4-inch audio cable
• A USB connection to the MIDI device
• Possibly, a BNC-to-RCA female adapter
Setting Up the LTC Source Device
The LTC generator should be set up as the master sync device. All timecode settings
should be set to “internal.” If available, Jog should be turned off. See the documentation
for your particular video deck or audio recorder for specific instructions.

528

Appendix C Working with Professional Video and Audio Equipment

Setting Up the MTC Generator
Set the MTC generator to receive LTC signals:
• In the case of the MIDI Timepiece, use the Clockworks control panel.
• In the case of the Unitor 8 MkII, use the Unitor Control application.
Setting Up Soundtrack Pro to Sync to External Timecode
You can set up Soundtrack Pro to sync to external timecode.
To sync Soundtrack Pro to external timecode
1 Choose Soundtrack Pro > Preferences, then click the Synchronization button at the top
of the Preferences window.

2 In the Input section, select the Sync to MIDI Time Code checkbox.
3 In the Output section, choose the frame rate for your project from the Frame Rate pop-up
menu.
4 In the Time Code Offset section, enter your tape’s offset in the Bar 1 At field. This is typically
01:00:00;00.
5 Close the Preferences window.
6 Depending on your timecode source, choose either View > Time Ruler Units > Drop Frame
or View > Time Ruler Units > Non-Drop Frame.
7 Choose View > Time Ruler Units > Set Starting Timecode.
8 In the dialog that appears, enter the SMPTE position where you would like the sequence
to start.
This often is the same as the tape offset. If your timecode source is drop frame, be sure
to select the Drop Frame checkbox.

excellent, free resource for Soundtrack Pro users. To access the AppleCare Knowledge
Base, go to the AppleCare support page at http://www.apple.com/support.
• AppleCare Support: There are a variety of support options available to Soundtrack Pro
customers. For more information, see the AppleCare Service & Support Guide that comes
with your Soundtrack Pro documentation.

Solutions to Common Problems
The following sections address some common issues:
• Audio Files and Audio Interfaces
• Eliminating Recording Latency

539

Audio Files and Audio Interfaces
There are several factors that can affect performance when working with digital audio
files. Observing the following guidelines will help you maintain the highest possible
performance when working with Soundtrack Pro projects:
• Because digital audio files require intensive processing by the computer’s processor,
do not perform other processor-intensive tasks while working in Soundtrack Pro.
• External audio interfaces connected to your computer can be susceptible to latency, a
noticeable delay between the time the audio signal is produced and the time it reaches
the computer. Some hardware and software manufacturers offer guidelines for reducing
the amount of latency for their equipment. Be sure to read the documentation that
came with your audio interface.
• If you are using a USB audio interface, make sure the audio interface is directly connected
to your computer. Do not connect a USB audio interface through a USB hub, or chain
it through another USB device.
• If you experience unwanted noise or hiss, check the connections between your computer
and any external audio devices. Refer to the documentation that came with each device
for any additional instructions on dealing with noise.

Eliminating Recording Latency
You can use the Latency Compensation setting in the Preferences Recording pane to
eliminate any latency inherent in your recording device.
To calculate the latency by playing a loop and recording it at the same time
1 Use an appropriate cable to connect the audio output port you are using to the input
port for the device from which you plan to record.
2 Choose a loop with a large number of transients, such as a drum loop.
3 Set the tempo to 60 bpm (to simplify the latency calculation).
4 Click the Arm for Recording button in the header of the track to which you want to record.
5 In the Recording tab, set the Input device to the recording device.
6 Set Monitor to None and ensure that hardware monitoring on your recording device is
turned off. You may also need to reduce input or output volumes of your devices in order
to avoid feedback.
7 Click the Record button (or press Command–R) and let the loop play for a few seconds.
Then click Stop.
8 Do the following:
a Visually compare the original track and the newly recorded track.
b Zoom in to identify a place where the tracks have identical waveforms but are not lined
up.

540

Appendix E Solving Problems

c Set the playhead at the corresponding identical points on the two waveforms and
subtract the two Beats field values.
This is the latency in milliseconds.
d Enter the latency value in the Recording Preferences pane.
If the recorded audio is late (to the right), enter a positive value; if it’s early (to the left),
enter a negative value. For example, if the location in beats of the selected point in the
source loop is 1.2.002 and the location in beats of the corresponding point in the
recording is 1.2.008, the latency is 6 milliseconds.
9 Mute the recorded track and test record the loop again to make sure the latency is
eliminated.

Contacting AppleCare Support
Included in your Soundtrack Pro package is documentation about the support options
available from Apple. Several levels of support are available, depending on your needs.
Whatever your issue, it’s a good idea to have the following information immediately
available. The more of this information you have ready to give to the support agents, the
faster they will be able to address your issue.
