purposes. You must reproduce and include the copyright notice on the

1a. GRANT OF LICENSE (SINGLE USER). In consideration of payment of the
single user license fee, which is part of the price you paid for this
product, BIAS, as Licensor, grants to you, LICENSEE, a nonexclusive
license to use and display this copy of a BIAS software program (the
“SOFTWARE”)
and
accompanying
user
documentation
(“DOCUMENTATION”). LICENSEE may install and authorize the
SOFTWARE on one COMPUTER, provided that (a) the COMPUTER is
owned by (or leased to) and under exclusive control of the Licensee; (b)
the SOFTWARE shall NOT be used simultaneously on more than one
COMPUTER at a time, and (c) any COMPUTER(S) with BIAS Software
installed shall not be sold, rented, leased, loaned or otherwise be
removed from the LICENSEE’s possession without first removing and
deauthorizing the Software, except as provided in Paragraph 6 (below)
pertaining to “TRANSFER RESTRICTIONS.” BIAS reserves all rights not
expressly granted to LICENSEE.
1b. GRANT OF LICENSE (MULTI-USER SINGLE SITE LICENSE). In
consideration of payment of the multi-user single site license fee, which

you, LICENSEE, a nonexclusive license to use and display this copy of the
Software and Documentation. LICENSEE may install and authorize the
SOFTWARE on a number of COMPUTERS equal to or less than the
number of licenses purchased (e.g. a 5 User Lab Pack allows up to 5 BIAS
SOFTWARE licenses at a single SITE to be simultaneously installed,
authorized, and used on up to 5 COMPUTERS at said SITE), provided
that (a) each COMPUTER is owned by (or leased to) and under exclusive
control of the Licensee; (b) the SOFTWARE shall NOT be used
simultaneously on more COMPUTERS at a time than the number of
licenses purchased as part of the multi-user single site license, and (c)
any COMPUTER(S) with BIAS Software installed shall not be sold, rented,
leased, loaned or otherwise be removed from the LICENSEE’s
possession without first removing and deauthorizing the Software,

THE SOFTWARE AND DOCUMENTATION (INCLUDING INSTRUCTIONS FOR
USE) ARE PROVIDED “AS IS” WITHOUT WARRANTIES OF ANY KIND. FURTHER,
BIAS DOES NOT WARRANT, GUARANTEE, OR MAKE ANY REPRESENTATIONS

your receipt. Further, BIAS hereby limits the duration of any implied
warranty(ies) on the media to the respective periods stated above. Some states

option, either (a) return of the purchase price or (b) replacement of the media
that does not meet BIAS’ Limited Warranty and which is returned to BIAS with a

the purchase price. Any replacement media will be warranted for the remainder

THE ABOVE ARE THE ONLY WARRANTIES OF ANY KIND, EITHER EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, THAT ARE
MADE BY BIAS CONCERNING THE BIAS PRODUCT. NO ORAL OR WRITTEN
INFORMATION OR ADVICE GIVEN BY BIAS, ITS DEALERS, DISTRIBUTORS,
AGENTS, OR EMPLOYEES SHALL CREATE A WARRANTY OR IN ANY WAY
INCREASE THE SCOPE OF THIS WARRANTY, AND YOU MAY NOT RELY ON ANY
SUCH INFORMATION OR ADVICE. THIS WARRANTY GIVES YOU SPECIFIC
LEGAL RIGHTS. YOU MAY HAVE OTHER RIGHTS WHICH VARY FROM STATE TO
STATE.
NEITHER BIAS NOR ANYONE ELSE WHO HAS BEEN INVOLVED IN THE
CREATION, PRODUCTION, OR DELIVERY OF THIS PRODUCT SHALL BE LIABLE
FOR ANY DIRECT, INDIRECT, CONSEQUENTIAL, OR INCIDENTAL DAMAGES
(INCLUDING DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS

they are not required.

turn off AppleTalk, unless you need to be on a
network.
•

Optimize your hard drive. (See Chapter 3 to learn
about proper hard disk maintenance.)

•

Use a separate (i.e., a drive that is not also hosting
the operating system or Peak application) fast hard
drive as a scratch disk/record disk – BIAS
recommends at least a 7200 RPM rotational speed,
8 MB cache or higher, 18ms access time or better,
and a fast data transfer connection, such as SCSI,
FireWire 400/800, ATA, etc.

About Your User’s Guide
Peak is designed to be simple and intuitive. Your User’s
Guide is designed to help you set up and use Peak for
digital recording and editing as quickly and easily as
possible.
This User’s Guide assumes that you are familiar with
standard Macintosh operating techniques, including:
•

Setting up, starting, and using your Macintosh

•

Choosing commands from menus

•

Clicking, double-clicking, selecting, Shift-selecting,
dragging with the mouse, and other common
operations

•

Opening, copying, saving and deleting files

•

Registration & Authorization
Peak must be authorized to work on your computer. You must
register Peak with BIAS in order to authorize it. BIAS offers a
variety of methods to authorize your computer – though
registering and authorizing via the internet with the computer
on which Peak will be run is by far the fastest and easiest
method. This and alternate methods are outlined below.
Serial Number-Based Authorization System

Peak’s standard authorization system consists of the
following components:
•

You must register with BIAS in order to authorize
your computer – Peak will not launch unless your
computer is authorized to run it.

The registration/authorization process provides the
following services:
•

Registers your software with BIAS - making you
eligible for technical support and product updates.

•

Authorizes your computer so it can run Peak. You
may authorize up to two computers for use with
Peak – for example, a studio or office computer,
and a laptop for home or mobile use.

BIAS Authorization Manager – A simple application
for managing BIAS software licenses.

•

Serial Number –

•

Registration Account – Your registration and
authorization information on the BIAS Server.

•

Authorization Request File –

•

Authorization File –

Keep in mind that for each license of Peak – the
software may only be used by one user, on one
computer system at a time. If you have used both
of your authorizations, and need to authorize a
new computer, you will need to first de-authorize
one of the authorized computers before you are
issued a new authorization for the new computer.

Optional BIAS USB Key-based Authorization

Users who prefer the BIAS USB key-based authorization
system to the standard serial number authorization
system may purchase a key separately, or use an existing,
authorized USB key from a previous version of Peak.

1. Launch Peak – the first time it is launched on an
unauthorized computer, you will be prompted to
use it in trial mode, or to authorize it – click the
Authorize button.
2. When the BIAS Authorization Manager appears,
select BIAS Peak Pro 5.x in the “Please Choose a
Product” section – then enter your Peak serial
number and email address in the appropriate
fields, and click the Authorize button.

Multi-user or site-license keys are also available, and may be
more convenient than using serial numbers in academic
“lab”, or corporate settings. For more information on
purchasing BIAS USB keys, please contact BIAS Sales, at:

make a note of which one you registered with –
this will make managing your BIAS Registration
Account faster and simpler in the future.

3a. If you have previously registered another BIAS
product, using the same email address, Peak will be
authorized automatically – please continue to step 4.
3b. If the BIAS Registration system does not recognize
your email address (i.e., if this is the first BIAS product
you are registering, or if you enter a different email
address than with previously registered BIAS
products) – a dialog will appear, prompting you to
enter your registration information. Enter your
registration information, and click the Submit button
– a dialog will appear indicating that you have been
successfully registered – please continue to step 4.
4. A dialog will appear indicating successful authorization –
click the OK button, and then click the Done button to
exit the Authorization Manager, and begin using Peak.
Alternate Methods of Registration/Authorization

If the computer on which you plan to use Peak cannot be
temporarily connected to the Internet, even for this onetime authorization process, there are a number of other
ways to register and authorize Peak.
Authorizing Peak with an existing BIAS USB Key (Dongle)

If you have upgraded from an earlier version of Peak,
which used a BIAS USB Key for copy protection, and
prefer to continue using key-based authorization –
simply plug in the key and your computer will be
authorized with the existing Peak authorization on it.
If you choose this method of authorization, be
aware that you will need to have your BIAS Key
with you, and plugged into your computer when
you wish to use Peak!

Registering & authorizing Peak using another
computer with internet access

To use this method of registration/authorization, you will
need to run the BIAS Authorization Manager application

Introduction
This chapter explains several key Peak concepts and
functions, including how to open, close, and save audio
documents.

A Brief Explanation of Digital Audio
If you are new to digital hard-disk-based recording, you
may wish to acquaint yourself with a few of the principles
behind digital audio before you dive into using Peak
software. This section explains a few key concepts that
will give you a good general understanding of how Peak
does what it does.
What we hear as sound is actually a pattern of pressure
waves that move through the air. The frequency of these
waves determines the pitch of the sound – how low or
high it sounds. Sound frequency is measured in cycles
per second, or Hertz (Hz). The range of human hearing
is generally considered to be from about 20 Hz at the low
end to 20 kHz at the high end. In practice, however,
most adults hear only as high as 12 kHz to 18 kHz,
especially those of us who may have spent more time
than we should have with headphones or at loud rock
concerts.
Sampling and Sample Rate

Your Peak software-equipped Macintosh computer
stores audio digitally. This means that analog electrical
signals from microphones or other sources are
converted into numbers by a circuit called an analogto-digital converter and stored on hard disk. The

analog-to-digital (A/D) converter uses a technique
called digital sampling to convert analog electrical
signals into numbers. Digital sampling is the sonic
equivalent of taking a snapshot. By taking thousands
of little digital samples per second and storing them to
a hard drive, an A/D converter can capture an accurate
sample-by-sample representation of a sound, much like
a movie is a frame-by-frame representation of a moving
image. The number of samples taken of the audio in a
second is called the sample rate. The sample rate
determines the recording’s upper frequency response.
A higher sample rate delivers higher frequency
response. As a rule of thumb, a digital recording’s
upper frequency response is roughly half of its sample
rate (known as the Nyquist frequency). The audio on
compact discs, for example, is recorded at 44,100
samples each second, or 44.1 kHz. This sample rate is
the standard for professional-quality digital audio, and
provides an upper-end frequency response of
approximately half the sample rate (known as the
Nyquist frequency): 22.5 kHz, somewhat higher than
most people’s hearing range.
Bit Resolution

Another factor that affects the quality of the audio is
the resolution of each sample. The greater the
resolution, the better the quality. To use an analogy
from the film world, just as image resolution and
quality increase with film size (8 millimeter film is
much lower in image quality than 70 millimeter film)
greater bit resolution (8-bit, 16-bit, 24-bit, and 32-bit)
results in better fidelity digital audio. Audio CDs have
a resolution of 16-bits.

Chapter 3: Peak Basics

33

In practice, the bit resolution determines the
recording’s dynamic range-that is, how many distinct
steps you have to describe a sound’s level, from quiet
to loud. For instance, an 8-bit recording has 256 (28)
levels available, which is the equivalent of 48 decibels
(dB) of dynamic range. On the other hand, a 16-bit
recording has 65,536 (216) levels available, equivalent
to 96 dB dynamic range. (The rule of thumb for
determining the dynamic range in decibels is to take
the bit rate and multiply it by 6.)

About Disk-Based Recording and
Editing
If you are new to hard-disk-based recording, you will
be impressed by the power and control that Peak
software provides for recording and editing digital
audio. You will encounter several new concepts and
techniques for using a disk-based system such as
Peak. Perhaps the most important among these is the
concept of nondestructive manipulation of audio.
Nonlinear Versus Linear Recording

Nondestructive audio manipulation is possible
thanks to the nature of Peak’s recording medium: a
hard disk instead of a roll of analog tape. Unlike
analog tape, which is a linear recording medium,
hard disks provide a nonlinear, or random-access
medium. This is because audio is stored on hard
disk as digital information which the hard disk can
access immediately or randomly (hence the term
“random-access”), simply by moving its read/write
head to the appropriate location and reading the
appropriate data. This allows you to perform such
miraculous feats as cutting and pasting “pieces of
sound” and rearranging material long after it has
been recorded.

34

Nondestructive Editing

Perhaps most impressive is the fact that with diskbased audio production you need not actually modify
the original source material in any way to accomplish
these feats. In most cases, by cutting and pasting you
are in reality only asking the hard disk to access
portions of the audio file in a slightly different order.
Since Peak doesn’t normally cut up, move around, or
delete the actual recording on the hard drive, it’s said
to be a nondestructive editing system. Peak does not
rewrite the file until you choose to save your edits.
Other manipulations, such as playing audio material
backwards, can be accomplished by reading the data
in reverse order. The power and flexibility of diskbased audio production software such as Peak far
surpasses the capabilities of traditional analog audio
production tools.
Hard Disk Storage Requirements

The actual recording of audio to hard disk requires a
significant amount of storage. This is directly affected
by the sample rate and bit resolution at which you
record: the higher the fidelity, the greater the
requirements for storage. As a guideline, 16-bit, 44.1
kHz audio requires roughly 5 megabytes of storage
per minute of mono recording. Stereo 16-bit, 44.1
kHz audio requires roughly 10 megabytes per minute.
Stereo 24-bit, 44.1 kHz audio requires roughly 15
megabytes per minute.
Hard Disk Maintenance

Because audio recording and playback is a hard diskintensive task, it is important that your hard drive be in
good operating condition. In the computer world, this
means keeping it from becoming fragmented by using
hard drive maintenance software. Fragmentation
occurs as your hard drive begins to run out of
contiguous (uninterrupted) space where it can write
files. If the data that makes up a file is stored at a single
location on your drive, it is much easier and faster for
your drive to find the data and read it. However, as

Peak 5 User’s Guide

contiguous space runs out, the drive may not be able
to write the entire file in one location and instead must
fragment the file by writing pieces of it at various
locations in whatever smaller open areas it can find.
This requires that the drive search near and far to read
the pieces of the file. Too much fragmentation can lead
to errors in recording and playback as the hard drive
struggles to keep up with the demands of your audio
application. In general, you should keep your hard
disk below 10% fragmentation. Most hard drive
maintenance software packages let you monitor the
degree of fragmentation on your drive and defragment
it by rewriting files into contiguous blocks of data. In
addition to defragmenting your drive regularly, you
should also back up your files and reformat your drive
on a regular basis to keep your system in top operating
condition. By doing this, you will ensure maximum
performance from your Macintosh and Peak software,
and keep your studio running smoothly. Now that you
understand some of the basic principles behind digital
audio and disk-based recording, take a few moments to
learn some of the basic operations of Peak. These are
covered in the sections that follow.

3
Creating a new mono audio document

Opening Existing Audio Documents
Peak allows you to open audio files created in a
variety of common audio formats including AIFF,
Sound Designer II, WAVE, QuickTime, Raw, System 7
Sound, Sonic AIFF, Paris, Jam Image, AU, MP3, and
AAC/MP4.
Peak will not allow you to open and edit protected
AAC/MP4 files, such as music purchased from the
iTunes Music Store.

Opening WAVE files

Creating a New Peak Document
Peak will allow you to create an empty audio file of
zero duration by choosing a new mono or stereo
document. However, you would typically record a
new audio file in Peak or open an existing audio file
into Peak for editing. Peak allows you to have
multiple audio documents open at the same time.
To create a new audio document:

Choose New (-N) from the File menu or Toolbar.
This command provides a hierarchical menu, which
allows you to choose either a mono or stereo format
for the new document.

The Macintosh recognizes files using a “type” and
“creator”. WAVE files are recognized by some audio
applications with a type “.WAV”, while others
recognize only “WAVE” as the type. Peak, along with
Apple’s QuickTime software and most other
multimedia applications, recognize WAVE files of the
type “WAVE”, but not of type “.WAV”. You can use
ResEdit or other third-party applications to ensure
your WAVE files have the correct type prior to opening
them with Peak.
Opening Compressed Audio Documents

AIFF/AIFC and QuickTime files with compression
such as MACE 3:1, MACE 6:1, IMA 4:1, QDesign, or
Alaw are compatible with Peak.

Chapter 3: Peak Basics

35

To open an audio file:

1. Choose Open (-O) from the File menu.
2. In the dialog that appears, locate the file that
you wish to open. From this dialog, you can
open AIFF, Sound Designer II, WAVE,
QuickTime, Raw, System 7 Sound, Sonic AIFF,
Paris, Jam Image, AU, and MP3 formatted audio
files.

Recently opened documents are displayed in the lower portion of the
File menu

The Open dialog

3. When you find the file you wish to open, click the
Open button and Peak will open the audio file into
a new audio window, displaying an overview of the
entire sound. Shift-click or -click to open
multiple files.
Recently Opened Documents

Peak automatically remembers up to the last eight
audio documents that you have opened and keeps a
list of these at the bottom of the File dialog. This
allows you to easily select a document’s name and
reopen it without having to search on your hard drive.
Peak can find and open a document even if you have
changed its location on your hard drive. If you
change the name of the file, the next time you open
Peak, it will automatically update the name in its
internal list.

Opening “Dual Mono” Files
Certain audio applications, such as BIAS Deck, do not
directly support stereo interleaved files, and instead use
“dual mono” files, which comprise the right and left
channels of stereo material. Peak allows you to open such
dual mono files, and in the process creates a new interleaved
stereo audio document. Because Peak actually writes a new
stereo audio file to disk, this conversion process requires
hard disk space equivalent to the two original mono files.
Please note that the Import Dual Mono command
requires that both files be mono files and have the
same sample rate.

To open a dual mono file:

1. Choose Import Dual Mono from the File menu.
2. In the dialog that appears, locate the desired files.

36

Peak 5 User’s Guide

3. Select either half of the dual mono file and click
Open. Peak imports the first file and then prompts
you for the second.
4. Select the second audio file and click Open. When
Peak has finished creating the new stereo audio
document you can begin editing.
For simpler importing of Dual Mono files, turn on
the Auto Import Dual Mono feature in the Optinos
menu. With this feature activated, you can
automatically import dual mono files by choosing
Open from the File menu and selecting one of the
dual mono file’s channels. Peak will then create a
new stereo document containing both channels.
Please note that these dual mono files must have
exactly the same file name with the suffix “.L” for
the left channel and “.R” for the right channel.

Peak allows you to drag a CD audio track directly onto
the Peak icon or open the track directly from the Open
command under the File menu or Toolbar. When you
import a CD track using one of these two methods, the
entire track will be imported. If you do not want to
import an entire audio track, you can still use the Import
CD track command under the File menu (covered in
Chapter 4).

Recovering Damaged Audio Files

Peak also allows you to export your stereo audio documents
in Dual Mono format, which means that it’s easy to import
dual mono tracks from BIAS Deck into Peak, edit and
process them within Peak, and then export them as Dual
Mono files to be reincorporated into your Deck sessions.
The Recover Audio File dialog

Dragging and Dropping Folders,
Disks, and CD Audio Tracks
In addition to opening individual documents by dragging and
dropping them onto the Peak application’s icon, you can drag
and drop entire folders or disks onto the Peak application’s
icon. The contents of the disk or folder(s) will be scanned for
audio documents that Peak can open, such as AIFF, Sound
Designer II, WAVE, QuickTime, MP3, and so on.
This feature is particularly useful when used with
Peak’s Batch File Processor.

Peak 5 includes a new tool called Recover Audio File,
which allows you to open a damaged file, and attempt to
recover the audio data contained in it. This tool extracts
audio data only, and ignores all other information
contained in the file’s header, such as information about
loop points, regular markers, region markers, etc. When
audio data is successfully recovered, it is placed into a
new audio document and must be saved.
There are a few pieces of information that Peak requires, in
order to attempt file recovery – these include the number of
channels, the file’s bit depth and sample rate, the audio data
location, and the byte order. With these few bits of
information (and depending on the degree of damage),
Peak may be able to recover many otherwise unusable audio

When the Recover Audio File encounters corrupt sectors
with media, file, or I/O errors, it will attempt to continue
recovering whatever audio data is available, and will write
the sections containing errors as silence in the new audio
file that is created.

Saving and Closing Documents
It is good practice to save regularly throughout a project
to avoid losing valuable work in the event of a power
failure or other unfortunate occurrence. The Save
command saves the changes you have made to your
audio document by writing it to your hard disk.
The Save command cannot be undone. If you want to be
able to continue to undo your edits, use the Save a Copy As
command under the file menu. Peak allows you to save your
audio documents in a variety of common audio file formats,
each of which is described below. Be aware that different
formats allow different information to be stored with the file.
Peak preserves this information unless you save the file into
a different file format. Saving a file in a format different from
its original format may, however, cause some information
stored in the file to be discarded.
New in version 5 is support for Unicode
characters. This allows non-English characters to
be used when saving files, and also allows the use
of “long” filenames (longer than 32 characters).

This is the header-less raw file format that
may be useful for some game platforms.

Peak 5 User’s Guide

Encoding as mp3 format requires that the LAME
encoder be installed. For more information on
downloading and installing this encoder, please
see Appendix 3, which contains step-by-step
directions for using the LAME encoder.

To save a Peak document:

1. Choose Save from the File menu or press -S on
your keyboard.
2. Select a file format from the pop-up File Type
menu. AIFF is Peak’s default audio file format.
3. Enter a name for the new audio document, select
where you want to save the new file, and then click
Save.
Using the Save As and Save A Copy As
Commands

The Save As command allows you to save a copy of
the current document under a different name, or in a
different location on your hard disk. Since the Save
As command closes the current document and lets
you keep working on the renamed copy, it is useful
for saving successive stages of a project. This allows
you to save each major step under a different name.
Later you can retrace your steps should you want to
go back to an earlier version. The Save A Copy As
command will save a copy of the file you are working
on, but it will keep the copy you are working on open.
This allows you to continue working on your audio
and still be able to undo any edits you executed prior
to using the Save A Copy As command.

2. Select the desired file format from the File Type
pop-up menu. AIFF is Peak’s default audio file
format.
3. If you wish to save the audio document to a
different bit depth resolution, click the bit
depth pop-up. It is strongly recommended that
you enable the POW-r™ dithering option if you
are saving to a lower bit depth (e.g., 24-bit to 16bit).
4. Enter a name for the new audio document, select
where you want to save the new file, and click Save.
Using POW-r Dithering

If you are saving to a lower bit depth (e.g., 24-bit to
16-bit), it is strongly recommended that you enable
the POW-r dithering option. Choose the POW-r
Dither Settings from the Preferences dialog to adjust
the settings for POW-r dither. For mono files, or
stereo files with a narrow stereo field (e.g.,
recordings of solo instruments), use POW-r 1; for
more stereophonically complex material, use POW-r
2; for full-spectrum audio with a wide stereo field,
use POW-r 3.

To save an audio document under another name:

1. Choose Save As (-Shift-S) or Save A Copy As (Option-S) from the File menu. The Save dialog
appears:

The POW-r™ Dither Settings dialog

Saving Compressed Audio Documents

AIFF/AIFC and QuickTime files with compression such as
MACE 3:1, MACE 6:1, IMA 4:1, QDesign, or Alaw are
compatible with Peak.
The Save dialog

You can only Save with file compression using
AIFF or QuickTime file formats.

Audio compression should be the last step in
mastering your audio documents. Decompressing
and re-compressing audio documents will
degrade their sound quality each time they are recompressed, so it is best not to save with
compression until all editing and mastering has
been completed.

To save an audio document with compression:

1. Choose Save As (-Shift-S) from the File menu.
The Save As dialog appears.
2. Choose the audio compressor you wish to use
from the Compressor pop-up menu. Some
compression formats only work with 8-bit or 16bit data, so the compression options may be
grayed out, depending on your setting in the bit
depth pop-up menu. Some of the types of
available audio file compression include: MACE
3:1, MACE 6:1, QDesign Music, ALaw 2:1, 32-bit
Floating Point, 64-bit Floating Point, IMA 4:1, 24bit integer, 32-bit integer, 16-bit Little Endian,
and 16-bit Big Endian.
3. Click the Options button to adjust the settings
for the specified compression format, and then
click OK.
4. Type the name of the new audio document,
select the folder you wish to save the audio
document, and click Save.
Closing Audio Documents

To close a file in Peak, choose Close from the File
menu (-W ). If you have made any changes to your
document since the last time you saved, Peak will ask
you if you want to save them. If you do, choose Yes;
if you do not, choose No. If you change your mind
and wish to continue your session, choose Cancel. To
close all files currently open in Peak, choose Close All
from the File menu (-Option-W ).

Peak Windows and Palettes
There are several windows and palettes when you
open Peak that either appear by default or are
available to you under Peak’s Windows menu.
Windows that appear in Peak by default include an
audio document window for each audio file you have
open. Windows and palettes that you can turn on or
off include the Transport, the Toolbar, the Contents
Window, and the Movie Window. This section will
cover the basic function of these Peak Windows and
Palettes.
Peak Audio Document Window

Peak Audio Document windows contain a Waveform
Display, an Audio File Info Bar, a Max Level Indicator
in the lower left corner, and an expandable contents
drawer which contains information about markers,
regions, and loops. The Waveform Display is a
graphic representation of the audio file, the Audio
File Info Bar shows the sample rate, bit resolution,
file format and file size of the audio file, and the Max
Level Indicator shows the highest amplitude level in
the audio file. On top of the Audio Document
window is the File Overview, if it is enabled under
the Peak Options menu. The contents drawer is
similar to the Contents Window, but offers a
convenient way to view regular, region, and loop
markers on a document-by-document basis, as well
as a complete edit history for that document. The
Audio Window is described in more detail in Chapter
5.
Peak’s audio document window also contains several
different tool icons representing different cursor
modes. The default cursor is a standard Arrow
Cursor. You can also use the cursor palette to select
a Hand Cursor for scrolling a Pencil Tool for drawing
directly on the waveform at the sample level, and a
Magnifying Glass Tool for zooming the waveform
view in and out. The ESC key on your computer
keyboard will toggle through the four cursor modes.

To access any of these cursors or functions, just click
on the corresponding icon. To change the cursor
tool, click on a new icon. The various cursors and
editing modes are discussed briefly below, and in
greater detail in Chapter 5: Editing.
Blending On/Off Button

When Blending is turned on, Peak creates very short
crossfades between sections of audio that are cut,
pasted, copied, or inserted. Blending helps to avoid
clicks and pops that can occur when cutting an audio
waveform at a non-zero crossing, or when combining
material with significantly different amplitude. The
left-most button toggles Blending on and off, and
the Caps Lock key on your keyboard may also be
used to toggle it on and off. More information on
using Blending is available in Chapter 5: Editing.

Horizontal Lock Button

The Horizontal Lock button allows both the Begin &
End markers in a loop or region to be moved
simultaneously. This feature is very useful in
situations where the duration of a selection needs to
be maintained, but the selection needs to be made in
a different part of an audio document. The secondfrom-left button toggles Horizontal Lock on and off.
Vertical Lock Button

The Vertical Lock button allows back-to-back Region
markers sharing the same space between samples to
be moved simultaneously. This is very useful when
cutting a long DJ mix or live recording into “tracks” –
when you need to adjust where a track break will
occur, without introducing any gaps between the two
regions.
Arrow Cursor Tool

The Cursor Tool is the default tool. It is the standard
“arrow” tool that lets you click and select on-screen
items.

Hand Tool

Cursor and Selection Information

The Hand Tool lets you scroll a waveform in its window.

The lower section of the audio document window’s
Contents Drawer displays the X (time) and Y (amplitude)
coordinates of the cursor point, Sel: the duration of any
currently selected audio), DTR (Distance to Reference
Marker), and BPM: the tempo in beats per minute. You
can type a value in for the X, Sel, and BPM parameters.

Magnifying Glass (“Zoom Tool”)

To use the Magnifying Glass tool, simply click on the tool
in the audio document window, then move the cursor
over the waveform. A “plus” (+) sign will appear inside
the Magnifying Glass. Click on the waveform to zoom in;
each click of the mouse will zoom in farther. To zoom
out, option-click on the waveform. A “minus” (-) sign will
appear in the Magnifying Glass, and you can click on the
waveform to zoom out. Double-clicking on the
Magnifying Glass will open the Zoom Amount dialog
where you can specify the Zoom Amount.

The same information can also be displayed by toggling
the transparent cursor overlay to the “on” position,
which appears next to the mouse cursor, and moves
along with the mouse cursor. Transparent cursor
information can be turned on and off under Peak’s
Options menu (-Shift-T).

The cursor overlay follows the mouse cursor as it moves, and displays
various types of information directly over the waveform

The time format displayed in these fields depends on
which time format (Samples, Min:Sec:ms, SMPTE, or
Bars|Beats) you have chosen with the Time Units
command under the Options menu.

Transport Window

The Transport window is a floating, re-sizable window. It
contains four main components: a time display showing
elapsed time, the Transport controls (Return to Zero,
Stop, Play, Go to End, Record, and Loop during
playback), audio level meters with clip/peak indicators,
and a master fader for playback volume control.
Time Display

Peak’s Time Display serves a number of functions. While
audio is playing, the Time Display shows the elapsed
time in the selected time units format, and tracks the
“playback head”, or cursor. When audio playback is
stopped the Time Display shows the current cursor
location within the audio waveform. Clicking the Time
Display opens Peak’s Go To Time dialog, and allows you
to enter a time value – the insertion point cursor jumps
to this time location in the audio document.
This display will also show the time remaining while
performing Open, Save, DSP processing, or CD-burning
actions.

The Peak Hold indicators appear as yellow bars at the far
right of each of the bar graphs as audio plays, and
selecting a hold time causes the indicator to pause for
easy reading of the peak value during playback. The Clip
Indicators appear as red bars at the far right of each of
the bar graphs as audio plays, and are triggered when
audio distorts, or “clips”, and selecting a hold time causes
the indicator to pause for easy reading of any clipping or
distortion that occurs during playback. Setting the Peak
Hold and Clip Indicator Hold Times to None turns these
features off.

The Meters dialog

LE

The Meters dialog is not available in Peak LE.

Progress Bar
Meters

Peak’s meters are much like the VU or LED meters on a
mixing board or tape recorder. They are bar graph
meters that show the relative volume or loudness of the
audio as it plays. They are also designed to show peak
volume and whether the signal has “clipped,” or
distorted.
The Meters dialog

You can configure the Meters display by choosing Meters
from the Audio menu, or by clicking the appropriate
button in the Toolbar. Using the Meters dialog, you can
select the Peak Hold time and Clip Indicator Hold Time.

The Meters display changes to a progress bar during
audio processing, and while saving or opening audio
files.
Master Fader

The Master Fader is located just below the level meters,
and is used to control the level of audio documents
being played back in Peak.

Playback Master Volume

Peak provides a master volume control for audio
playback. In the Playback Preferences dialog, set Peak’s
output volume to the level that you desire by adjusting
the slider or entering a number value from 0 (silent) to 7
(loudest). If you are controlling your playback volume
with the volume control of your playback system, you’ll
probably want to leave the output level set to 7.
Playback Buffer

Peak allows you to control the amount of RAM the
program uses when playing back audio documents.
In general, lower is better. A playback buffer setting
of 32 - 64k is a good place to start. If you are
experiencing clicks in your playback, working with
fragmented files, using processor-intensive real-time
DSP, or are using a slow hard drive, you may need a
larger playback buffer setting.

with a few large files, and smaller values if you are
working with many smaller files.
Dynamic Scrub Time

Peak provides a unique audio auditioning technique
called dynamic scrubbing. This feature is very useful
for precisely pinpointing and selecting a desired
location in an audio document. Dynamic scrubbing
allows you to drag the mouse forward or backward
over a waveform while Peak plays a short loop
(between 10 and 600 milliseconds) at the scrub
location. When you have found the location you are
looking for, let go of the mouse and the insertion
point will be exactly where you want it to be. Peak
allows you to choose the length of this playback loop
with the Dynamic Scrub Time command in the

Auditioning

Peak’s Auditioning command allows you to audition a
selection along with a specific amount of audio
preceding or following it. The Auditioning dialog allows
you to select a desired amount of pre-roll or post-roll
when you play the selection. To play a selection with the
selected amount of pre- and postroll, press ControlSpacebar.

Blending

Blending is an automatic crossfade function with a usereditable envelope. Peak can apply blending to areas of
an audio document when they are modified by cutting,
deleting, or other editing processes in order to smooth
abrupt transitions between waveform amplitudes. It can
be very useful for creating a smooth transition between
edits that would otherwise sound too abrupt. If you have
cut, pasted, or inserted audio into a document, you may
wish to enable blending to smooth things out a bit. It
can be toggled on or off by clicking the Blending button
in the Audio Document Window, or by using the caps
lock key on your keyboard.
To configure Blending:

1. Select Blending from the Preferences dialog. Enter
the Duration over which you wish Blending to
occur into the dialog box.
2. To edit the Blending Envelope, click on the Edit

The Auditioning Preferences dialog appears.
2. Enter the desired amount of Pre-roll and Post-roll,
and click OK.

Certain audio applications, such as BIAS Deck and
Digidesign’s Pro Tools, do not directly support
interleaved stereo files, and instead use “dual mono”
files-a pair of files, one for the left channel and one for
the right channel. These files have typically been
exported with the suffix “.L” for the left channel, and the
suffix “.R” for the right channel. Auto-Import Dual Mono,
when selected, will allow you to select just one channel
of the dual mono file in the Open dialog. Peak will
automatically “grab” the other half of the file, and convert
both files into a single stereo Peak document.

The Auditioning dialog

Choosing a time format with the Time Units command

Audio File Meter, Tempo, and Timestamp
Settings

If your audio document is using bars|beats as its units,
you will want to tell Peak what the tempo of the audio
document is. Use the Audio Info command from the
Options menu-or enter the BPM in the Cursor palette-to
set the tempo of the audio document. You can also enter
the meter of an audio document using the Audio Info
dialog. The numerator represents the number of beats
per measure, and the denominator represents the value
of a beat, where 4=quarter note, 8=eighth note,
16=sixteenth note, and so forth.

You may also enter a timestamp for the audio document in
seconds. If the audio document has a timestamp, then the
displayed time in an audio document will be offset from this
time rather than starting at zero. For example, if the
timestamp for an audio document is four seconds, then the
first sample in the audio document will appear in the audio
document with a time of 4 seconds instead of zero seconds.
Choosing a Scratch Disk

Because audio data can be very large, Peak utilizes a portion
of your hard disk’s free space to hold audio data that has
been cut or copied, as well as for temporary or scratch files
for undo purposes. If your hard disk is short on space, you
may not be able to cut, copy, or modify large selections. If
you have more than one hard drive attached to your
Macintosh, the Scratch Disks section in the Preferences
dialog allows you to choose the hard drives (or “scratch
disks”) that you wish to use for these temporary files. Peak
allows you to select which disk you want to have as your
default, or “Primary” disk for this purpose-usually you would
select the disk that has the most free space. If you are
connected to a file server, you can utilize available storage on
the server by clicking the Allow Servers checkbox. Any
available servers will then appear in the Scratch Disks popup menu. This feature is recommended only if you have
access to a high speed Ethernet, or other fast server.

Introduction
In this chapter you’ll learn how to play and record audio
with Peak. Peak allows playback of many digital audio file
formats, and can record any audio source that’s
connected to your Macintosh. Playback and recording
may be performed using either the built-in audio
hardware in your Macintosh, or with a wide variety of
third-party audio hardware interfaces (USB, FireWire,
PCI, PCMCIA, etc).
Peak may also be used as a host for playing and recording
virtual instrument plug-ins, recording soundtracks for
QuickTime movies, and importing tracks from audio
CDs.

Please note that this list reflects interfaces that
have been tested with Peak, and is updated
regularly. If an interface is not listed here, it does
not mean that it is not compatible with Peak. The
general rule for hardware compatibility is, if a
compatible Core Audio driver is provided by the
hardware’s manufacturer, or Mac OS X natively
supports the hardware device – Peak is
compatible with it.

For Peak to work properly with third-party audio hardware
devices, they must either be natively supported by Mac OS X –
or, you will need to install a compatible Core Audio driver
provided by the audio hardware manufacturer. Be sure to
consult the audio hardware manufacturer’s instructions when
installing & configuring your audio interface.

Core Audio
Peak supports Apple’s Core Audio when using the Mac’s
built-in audio hardware, as well as with third-party
interfaces, such as those made by Digidesign™,
Edirol™, M-Audio™, MOTU™, PreSonus™, Tascam™,
and many others.
A list of many compatible audio hardware interfaces is
available on the BIAS website:
http://www.bias-inc.com/support/hardware/

Using Core Audio is highly recommended! Using the
Sound Manager (i.e., Mac OS X HAL or FireWire DV)
settings is uncommon and is not addressed in this
chapter. The only reason to record or play back audio
using Sound Manager (Mac OS X HAL or FireWire DV) is
because you are using a third-party audio hardware
interface or other device (such as a DV camera) as an
input or output device – that is not compatible with Core
Audio. For more information on recording and
playback using Sound Manager (Mac OS X HAL or
FireWire DV) audio, please see Appendix 4.

Chapter 4: Playback & Recording

Configuring Peak for Playback
Whether you are using the built-in audio hardware in
your Macintosh, or a third-party interface, there are some
basic configuration steps you must perform before
playing back audio.
Hardware Settings: M-Audio Delta Control Panel

When launching Peak for the first time, a dialog
appears asking whether you would like to
configure your Audio/MIDI preferences. To
quickly set up your audio hardware for the first
time, click Yes.

6. Launch Peak.
7. From the Audio menu, select Sound Out>Core
Audio.

To Configure Peak for Audio Playback:

1. If applicable, install/connect your third-party audio
interface and its software according to the
manufacturer’s instructions.
2. Reboot your Macintosh.
3. Launch the System Preferences, and choose
Sound.
4. Select your third-party audio interface for Output.

The Sound Out submenu under the Audio menu

8. Select the Clock Source, Sample Rate, Play
Through, and Sample Rate Converter Quality
settings from the pop-up menus in the Core Audio
Playback dialog. Click OK, or for further options,

Peak 5 User’s Guide

Most audio interfaces can be adequately
configured using the Apple Sound Preferences.
Some more advanced audio interfaces may
require additional configuration. In this case the
Apple Audio MIDI Setup Utility may be used to
configure your audio hardware. The Audio MIDI
Setup Utility is installed in the following directory,
located in:

Sample Rate Pop-Up Menu

This menu allows you to choose the sample rate for
playback. The default sample rate setting is “Auto”.
Unless you specifically need to use another setting,
this is best left set to “Auto”.

Play Through Pop-Up Menu
Core Audio Settings

Not all hardware devices allow control over the
input level from within the Core Audio Settings
dialog.

This menu lets you choose the channels on your
audio interface that you wish audio to play out of. For
example, if you are using a hardware interface with
multiple outputs, you can select the appropriate
outputs to route audio output through to your
monitors/headphones.

Peak is now configured for playback with Core Audio.

Sample Rate Converter Quality Pop-Up Menu

Output Device pop-up menu

Peak features on-the-fly sample rate conversion, used
when playing back audio files with a sample rate not
natively supported by the audio hardware being used. A
setting of 1 gives the lowest quality sample rate
conversion, and uses the least amount of CPU resources.
A setting of 5 gives the highest quality, and uses more
CPU power. Depending on your Macintosh system’s
speed, you may need to experiment with this setting for
the best performance.

This pop-up menu allows you to choose the desired
audio hardware device to use for output, when more
than one is available.

Be aware that the setting used for Sample Rate
Converter quality also affects the quality of TapeStyle Scrubbing. BIAS recommends using the
highest setting possible that your computer system
is capable of.

Buffer Size pop-up menu

This menu controls the buffer size used, and is directly
related to the amount of latency that is encountered. It
is recommended that you use the lowest possible setting
that your computer is capable of. The easiest way to
determine the lowest setting your computer is capable of
is by doing test recordings – if you notice distortion, or
dropouts in the recorded audio, you will need to use a
higher setting. If you do need to raise this setting, it’s
best to do it by one setting at a time, for example, if your
system cannot handle using a 512k buffer size, raise it to
1024k and try again.

Core Audio Settings Dialog

Additional Core Audio options are available in the Core
Audio Settings dialog, which may be accessed by
choosing Hardware Settings from the Audio menu, or by
clicking the Hardware Settings button in the Core Audio
Playback dialog. These options include the following:

If your computer requires a relatively high buffer size for
smooth recording, and you need to monitor your audio
source, it is recommended that you set up your
equipment to allow direct monitoring from a mixer, or
from an audio interface that features direct monitoring.
Direct monitoring will eliminate the problem of latency,
in which you hear what is being recorded after a slight
delay, which is directly proportional to the buffer size
setting being used.
If you are playing virtual instruments and notice a
significant delay from the time you play a note, and the
time you hear it, you may want to experiment with lower
buffer sizes, to reduce the latency to the lowest possible
level that still provides smooth audio playback.

As explained earlier, Peak allows you to have multiple audio
documents open at the same time. Peak assigns each of
these documents a number based on the order in which it
was opened. Peak provides you with a convenient way of
triggering playback of any open audio document by pressing
a number key on your computer keyboard. This can be a
very useful feature for applications such as “live” sound
effects playback, since you can open multiple audio
documents and play them from your Macintosh keyboard.
To trigger sequential playback of multiple audio
documents:

1. Open several audio documents, taking note of the
number that Peak assigns them in the Window
menu. (This is based on the order in which the
documents were opened.)

Macintosh, use this pop-up to select your record
drive. (This option will default to the largest drive
currently available to your Macintosh unless you
select otherwise.)

The Monitor checkbox allows you to monitor the audio
throughput while you are recording.

Peak requires that you save the audio file to the
same drive on which it was recorded.

Split Stereo Files Checkbox

The Split Stereo Files checkbox allows you to record the
incoming stereo audio as dual mono files rather than a
single stereo file. Dual mono files are used in programs
like Pro Tools, or BIAS Deck, so this option is useful if
you need to record dual mono files (i.e., split stereo).
Append to Document Checkbox

File Format Pop-Up Menu

The File Format pop-up menu allows you to select the
file format for the audio being recorded. You may
choose from AIFF or Sound Designer II. If you need
the newly recorded audio file to be in a different
format, you can always use the Save As function to
save it as another format once recording is complete.
If you do not select a file format for recording, Peak
will default to AIFF.
Auto Gain Control Checkbox

The Auto Gain Control checkbox allows you to
enable/disable the Automatic Gain Control feature
used by the Sound Manager system with some
Macintosh microphone inputs. If the recording
device you are using supports this feature, and you
wish to use Auto Gain Control, check the Auto Gain
Control checkbox. It is normal for this checkbox to
be greyed out (unavailable) when using Core Audio.

Setup information for using the Sound Manager
system is available in Appendix 4 of this user’s
guide.

The Append to document checkbox allows you to record
into an existing audio document. To record new audio
into an existing document, place the insertion point in
the existing audio document at the point where you want
to insert the new audio. If the insertion point is at the
beginning of the file, the newly recorded audio will be
inserted at the beginning of the file. If the insertion
point is at the end of the file, the newly recorded audio
will be appended to the end of the existing file. If the
insertion point is somewhere in the middle of the file,
the newly recorded audio will be inserted at that point.
If you make a selection of audio, the Append to
document feature will allow you to replace the current
audio with newly recorded audio from the beginning of
the selection through the end of the document or
wherever you stop the recording.

document recording is finished, Peak will present
multiple Save dialogs (one for each 2 GB file, or fraction
thereof ), so each document may be saved separately.
The maximum recording length will vary depending on
the number of channels used, as well as bit depth and
sample rate. The maximum amount of disk space that
can be used in multi-document recording is 10 GB,
spread across five individual audio documents. This
amounts to approximately 16.5 hours of continuous
recording at CD quality settings (Stereo/16-Bit/44.1kHz).
The recording settings you choose will affect how long a
recording you can make.

The Recording Time dialog

Open After Saving Checkbox

The Open after saving checkbox determines whether the
audio document is opened in Peak after it is recorded.
Device and Sample Format Button

Clicking the Device and Sample Format button will open
the Core Audio Record Settings dialog, where you can
specify various recording options.
Hardware Settings Button

Clicking the Hardware Settings button in the Record
Settings dialog brings up the Core Audio Settings dialog,
where you can specify which hardware device to use
(when multiple devices are connected to your
computer), the buffer size, and the input level (if the
device supports adjustable input level).

For example, if you were to record 10 hours of audio at 16Bit/44.1kHz, you would be using approximately 600 MB of
disk space per hour. At this rate, after about 3.3 hours of
recording, you would have used about 2 GB of disk space.
When this 2 GB limit is reached, Peak would continue
recording, but now into a new document – the first
document is stored as a temporary file on the hard disk.
After another 3.3 hours, another 2 GB file is created, and
Peak continues recording into a third file. When we reach
9.9 hours, Peak begins recording into a fourth document –
this one being the remainder, or .1 hours (6 minutes). When
we stop Peak at the 10 hour mark, four consecutive Save
dialogs would be presented, allowing the four pieces of this
long recording to be saved. It’s a good idea to develop a
naming convention to address multi-document recordings,
such as naming your files “Part 1/4”, “Part 2/4”, “Part 3/4”,
“Part 4/4”, or something similar, that identifies each file as
part of the whole recording.
When editing files created during multi-document
recording, each one appears in Peak as a separate audio
document.

Multi-Document Recordings (Long
Recordings)
If you plan to make long recordings with Peak, be aware
that each individual audio document that Peak creates
has a maximum file size of just under 2 gigabytes (1.99 to
be precise). If a recording exceeds this length/file size,
Peak automatically creates a new document and
continues recording seamlessly. When a multi64

Configuring Peak to Record Through Effect &
Instrument Plug-Ins

If you have plug-ins installed, you can record through
them in real-time when using Core Audio. This is useful
if you want to use a noise reduction, equalizing, or
dynamics plug-in during recording. While recording
through plug-ins, you are free to adjust plug-in
parameters – however, be aware that you will be making
permanent changes to the material that is recorded, and
will not be able to undo these adjustments.
To configure Peak to record through Effects Plug-Ins:
The Record dialog

The Notepad feature in the Record dialog allows you
to type in text descriptions, transcribe a recording, or
type in comments called Notepad Cues at specific
points during the recording of an audio document.
The Notepad feature is available from the Record
dialog and may be used once a recording starts.
If you enable the Notepad checkbox, you can create
markers while recording. Each time you press the
Return key, a new Notepad Cue (marker) is
generated for the current recording time. You may
then begin typing text to describe the audio
recording at that time (i.e., naming the marker).
When you hear the next significant event in the
recording, press the Return key to create another
cue, and so forth.

1. From the Plug-Ins menu, open and configure the
plug-in(s) you wish to record through.
2. Select Record Settings from the Audio menu. The
Record Settings dialog will appear.
3. Check the Record Through Plug-Ins checkbox and
click OK.

4. Select Record from the Audio menu (-R) or
Toolbar. You are now ready to record audio
through the plug-in(s).
5. Be sure to disable the active effects plug-in(s) after you
have made the recording. (If effects plug-ins are active
when playing audio back, the signal passes through the

plug-in, and will double the effect of the plug-in on the
signal, and will not give an accurate representation of the
material being played back).
Peak can only record through plug-ins when using
Core Audio.

will open.
5. Play your instrument or audio source. You should
see the signal levels register on Peak’s Audio
Meters in the Transport window.
6. Adjust the output of your audio source so that its
signal registers relatively high on the meters but
never hits top (indicated by the red Clip
Indicators.). Remember to always leave 6 dB or so
of headroom on the meters so that you don’t clip.
Use the yellow and orange meter lights and red
Clip indicators to help you make this adjustment.

Recording
Once you have configured Peak for recording, you may
use the following directions to record audio from any
source connected to your Macintosh.

If the recording level “clips” (exceeds 0 dB, causing
digital distortion), you can reset the clip
indicators by clicking them with your mouse.

To start recording:

1. Turn down the volume of your instrument or audio
source.
2. Connect the instrument or audio source to the
audio input jack on the rear of your Macintosh. If
you are using third-party audio hardware device,
use the connectors on this device; many audio
devices have an external interface box which
contains the input and output connectors, if this is
the case, use these.
3. Choose Record Settings from the Audio menu
(Option-R) or Toolbar, and configure the settings as
described in the previous section. If you wish to
listen to the audio being recorded, make sure that
you have checked the Monitor On/Off checkbox in
the Record Settings.

7. Click the Record button in the Record dialog. You
are now recording to disk. You should see the
audio waveform begin to scroll in the Audio Source
Display window.
8. To stop recording, click the Stop button. To pause,
click the Pause button.
9. Once you have stopped recording, the Save dialog
appears and prompts you to name the audio
document. You must save the audio document to
the same hard drive you selected in the Record
Settings dialog. Enter a name and click Save. Peak
automatically saves the document in the audio file
format you selected in the Record Settings dialog.
If you wish to later save the document in a different
audio file format, use the Save As command.

4. Select Record from the Audio menu (-R) or the
Record button in the Transport. The Record dialog

When recording through an effects plug-in, be
aware that you will not be able to undo this effect.
If you are not satisfied with the recording, you will
have to re-record. If you are unsure about
recording through a plug-in, you may wish to
record a dry signal, and apply the effect after you
have saved the recording. This way, you can
experiment with effect settings and commit to
them only when you are satisfied.

Importing a Track from an Audio CD

into the computer’s CD-ROM drive. iTunes default
behavior is to automatically get the track names from
the CDDB™ online CD database. Once a CD’s tracks
are labeled, that information is available to any
application that imports a track, including Peak. This is
a convenient way to automatically name a CD’s tracks.

5. To select only a portion of the track, click on Set Import
Times button or double-click on the track in the list. The
CD Import Track Range dialog will appear.

Making Audio Connections
While it is possible to listen to audio playback in Peak
using a Macintosh’s built-in speaker or headphones,
most people will prefer to listen through a better quality
external speaker system.
It is very easy to set up audio connections between
your Macintosh and a mixer or speaker system. Your
exact setup will differ slightly depending on whether
you are using the built-in sound input and output
connectors on your Macintosh, or those of a thirdparty audio interface.
Using the Macintosh’s Built-In Inputs and
Outputs

To use your Macintosh’s built-in audio inputs and
outputs for recording and playback, do the
following:
The Import CD Track Range dialog

6. By adjusting the Start and End time controls in this
dialog you can import the entire CD track, or a just
specific portion of the track. You may also click
directly on the timeline to adjust start and end
points. Click Play to audition the CD track (or
selected portion of the CD track). Click OK when
you are happy with the selection.
7. Check the Open tracks after importing checkbox if you
want the CD track(s) you are importing to open in Peak.
8. Click the Import button in the The Import CD Audio
dialog to import the selected tracks and the Save
dialog appears. Use the pop-up menu at the top of
the dialog to navigate to the volume where you wish
to save the audio file. Click Save to save the file to disk.
Peak will save the file(s) in the AIFF audio format.

68

1. Turn down the volume on your playback system.
Peak can be used with a variety of playback
systems, including:
• Headphones
• A stereo receiver or amplifier and speakers
• A mixer, amplifier, and a pair of speakers
• A mixer and a pair of amplified (self-powered)
speakers
• A pair of amplified (self-powered) speakers,
smaller versions of which are often called
“multimedia” speakers.
2. Connect your audio source output to the
Macintosh’s audio input connector. Your audio
source can be one of a variety of devices, such as:
• A cassette or DAT deck output

Peak 5 User’s Guide

• A mixer output
• A stereo receiver line output (such as “tape
deck record” output)
•

An instrument line output (such as the output
of a synthesizer or guitar preamp)

The Mac’s audio input and output jacks are standard
stereo mini-plug (1/8-inch) connector. Most mixer,
receiver, and amplified speaker inputs are equipped with
XLR, 1/4-inch, RCA, or mini-plug jacks. To make the
proper connection, you may need to use an adapter.

Some Macintosh models may not have a built-in
sound input – in which case you will have to use
a third-party audio interface for sound input.
For advanced users: Certain professional mixing
consoles, DAT decks, or other audio sources may
have a nominal output level of +4 dBu, whereas
the Macintosh expects to see a nominal -10 dBV
level. Be aware that you may need to adjust your
mixer’s output levels accordingly to prevent
overloading the Macintosh’s input; or alternately,
you may need to use a “+4 to -10” line-matching
transformer.

Conclusion
You have now learned about how to configure Peak for
recording and playback with Core Audio, and how to
connect various types of audio equipment to your
computer. You’ve also learned how to record and play
back audio documents, and how to record through plugins, play & record virtual instruments, record into
QuickTime movies, and to import audio CD tracks.
Now that you’re familiar with setting up your equipment
to get audio into and out of Peak, continue along to the
next chapter, where you will learn how to edit audio with
Peak’s powerful set of digital editing tools.

Chapter 5:
Editing

Introduction
This chapter introduces you to the concept of digital
audio editing. You will learn how to edit digital audio
with Peak’s many powerful editing tools.

Editing Audio with Peak
Peak provides you with a powerful interactive,
nondestructive environment for editing and
manipulating audio. In this environment, not only are
virtually all editing actions completely “undo-able” and
“redo-able,” but they can be performed interactively
while audio playback is engaged.
Interactive Editing

Interactive editing means that you can cut, paste, loop,
and process audio with many of Peak’s DSP functions
and plug-ins, even while playing back the very audio that
you are editing. For example, you can start playback, cut
a selection of audio and paste or insert it later in the
document, and when Peak reaches the location of the
inserted audio, it will play it as if it were there all along.
This revolutionary capability makes Peak a supremely fast
and flexible audio production tool that makes
conventional recording and editing methods, such as
analog tape and a razor blade, seem primitive and archaic
by comparison.

5

Nondestructive Editing

Peak’s nondestructive editing capabilities mean
that the edits you perform to an audio document
do not permanently change the original source
recording until you finally save the document.
Thus, you can cut, copy, paste, fade in and out of,
and otherwise completely change a recording, and
still be able to return back to square one – the
original untouched state of the recording – up
until the time that you save the document to disk.
At that time, all edits are permanently written into
the document.
Unlimited Undo and Redo

As an editing session progresses, Peak maintains an
internal list of the edits that you perform. Changes
that you make to an audio document are not
permanently applied to the file until you ultimately
save it. This is what gives Peak its unprecedented
unlimited undo and redo capability. Through the
use of the Macintosh’s standard Undo and Redo
commands, you can undo or redo your actions
sequentially, or by using the Edits command, using
a “playlist-style” editing event list. This is a very
exciting technology that allows you to maintain
complete creative freedom of choice – right up
until the last moment before you save your project
to disk.

Chapter 5: Editing

75

The Audio Document Window

Vertical Scaling

The heart of Peak’s powerful editing capabilities is the
audio document window. The audio document window
provides you with a “window into sound,” allowing you
to make good use of both your eyes and ears to perform
extremely precise editing tasks. The audio document
window gives you a time-domain representation of
sound, that is, you see the amplitude of the sound over
time.

Peak allows you to control the vertical magnification of
audio waveforms. This feature is useful if you are editing
and viewing a document with very quiet audio material.
To increase the vertical scaling magnification:

•

Hold the Control key down and press the Up
Arrow key.

To decrease the vertical scaling magnification:

An Audio Waveform

•

If you have never seen sound displayed in a visual format
before, it may not be immediately obvious how to “read” an
audio waveform. It is actually quite easy to navigate through
a recording with a waveform as your road map. The peaks
in the waveform are areas of high amplitude (loud spots).
The valleys in the waveform are areas of low amplitude
(quiet spots). If the audio material is music with a
pronounced, regular beat, it is generally very easy to pick out
where the beats are simply by looking for peaks. Using this
information, and the guidelines given shortly in the “A
Selection” section, you will be able to successfully locate and
select a desired portion of the audio document and perform
the edits that you wish. The cursor marks the current
location, and also serves as an insertion point.

Hold the Control key down and press the Down Arrow key.

Audio Waveform Overview

Peak provides an Overview display of the entire audio
waveform along the top of the screen under the menu bar.
This provides you with a convenient visual reference of the
overall document when you are editing only a portion in the
audio document window. The highlighted area in the
Overview display shows the area of the audio waveform
currently visible in the audio document window. If desired,
you can hide the Overview display to allow the audio
document window to occupy more of the computer screen.
To show/hide the Audio Waveform Overview:

•

An audio waveform

Peak 5’s improved waveform display gives an even
more accurate representation of the digital audio
signal than in previous versions, and provides
more information about positive and negative
phase.

76

Select Show Overview in the Options menu (-,)
– a check next to this item indicates it is enabled,
and the absence of a check means it is disabled (or
click the disclosure triangle in the upper left corner
of the audio document window).

A Selection

A selection is just what it sounds like: a portion of audio that
you have selected by clicking and dragging with the mouse.
You must select audio in order to perform an editing action
on it. To make good selections for editing, the best rule of

Peak 5 User’s Guide

thumb is to begin a selection just before a peak in the
waveform and end it just after a peak in the waveform. In
other words, try to make selections start and end in areas of
low amplitude (“valleys” in the waveform).

A waveform with selected audio

It is also important, when possible, to begin and end a selection
at a point where the waveform meets the zero crossing line
(the center line through the waveform). This helps you avoid
creating pops and clicks if you later cut or paste the audio,
because the point at which the waveform meets the zero
crossing is a point of no amplitude in the sound wave. Pops
and click generally only occur if you make a careless selection
and begin or end on a portion of the sound wave where the
amplitude is high (where the waveform is high above, or far
below the center point). Enable Auto-Snap in the Options
menu, and select Snap To>Zero Crossings from the Action
menu to have Peak nudge your selection to the nearest zero
crossings automatically.
In addition to snapping to zero crossings in the audio
waveform, Peak features a number of other Snap To
options. These options allow a selection to be “snapped”
to a preset number of samples, or to a custom selection
length. Other Snap To boundaries include:
•

Bars/Beats

•

CD Frames (588 samples or multiple thereof )

•

Sony PS2 Loop Boundaries (28 samples or multiple
thereof )

•

Microsoft Xbox Loop Boundaries (64 samples or
multiple thereof )

•

Custom Units (user-definable number of samples)

The Snap To units you choose will depend on the type of
editing work you will be doing. Most users will probably use
Zero Crossings or Bars/Beats for most musical applications.
Multimedia and video game sound designers will especially
appreciate these new options when producing audio for a
particular delivery platform. For example, when creating
audio loops and sound effects for a Playstation 2 video game,
audio edits need to be made at increments of 28 samples in
order to loop/play back smoothly in the PS2’s audio engine.
By choosing the Snap To PS2 loop boundary setting, any edits
that are made will automatically be made in units that will
translate smoothly to the PS2’s playback system.
Once markers are placed in the waveform, they may
need to be moved. By holding down the Shift key while
dragging the markers the selected Snap To behavior will
be applied, and the markers may be shifted slightly so as
to conform to the selected Snap To format.
The Zoom In function helps you make very precise
selections by letting you zoom in to a higher
magnification and select exactly the portion of the
waveform you desire. Also, once you have made a
selection, you can adjust the beginning or the end of the
current selection by holding down the Shift key and
clicking with the mouse. Your selection will be
shortened or lengthened accordingly.
Channel Independent Processing

To select only the Left channel, move the cursor over it and
above the left channel’s waveform. The cursor will show a
small “L” at the insertion point. To select only the Right
channel, move the cursor over it and below the left channel’s
waveform. The cursor will show a small “R” at the insertion
point. You can process one channel of an audio document
using most of Peak’s native DSP or third-party plug-ins.

Chapter 5: Editing

Peak allows you to select and process the left and
right channels of a stereo file independently, but
you cannot edit (i.e., Cut, Paste, Delete, etc.) the
left and right channels of a stereo file
independently.
77

A Marker

Although Peak allows only one loop per audio
document, there is a quick and easy way to mark
multiple desired sections for looping. With the loop
markers in the desired location, choose Select Loop
from the Edit menu, then, choose New Region from
the Action menu – a Region is created that is the
same length as the loop. Using this technique allows
you to create as many Regions as desired within a
single audio document. To loop any of these Regions,
simply -click between a Region’s markers to select
the Region (or press the Tab key until the desired
Region is selected), and then choose Loop this
Selection (-Shift-“-“)from the Action menu.

A marker can be placed in a document to identify a
point of importance. A marker appears as a line
with a solid triangular base. Peak allows you to
place markers into a document in order to mark a
given location or Region in a document for later
selection, navigation, or editing. Markers can be
moved, named and renamed, “anchored” to a
particular location on a waveform, and given other
attributes. The use of markers is covered in
greater detail later in this chapter.

Audio Between Adjacent Markers

A waveform with a Marker (named “Verse2”)

A Loop

A loop refers to a section of audio that is bounded
on either side by loop markers. In the illustration
above, the area that falls between the loop markers
“beg loop” and “end loop” is looped. Loops are
used to sustain or repeat a section of audio. They
can be used for material that you intend to transfer
to a sampler, or simply for playback within Peak
itself. Peak allows you to create one loop per audio
file.

Audio between adjacent markers refers to a section of
audio that is bounded by markers. In the illustration
above, the area that falls between the Beat 1 and Beat 2
markers is audio between markers. (Note: A selection of
audio between markers is different than an audio Region.
Regions are described later in this chapter, as well as in
Chapter 6, Playlists and Audio CD Burning.)

will open the Change Gain dialog, so that you can change
the gain for the entire audio file, or the current selection.
For more information on the Change Gain DSP function,
please refer to Chapter 7: DSP. Clicking on any other
portion of the Audio Info Area will open the Audio Info
dialog.

To make a selection with the mouse:

•

Click the cursor at the desired start location in the
audio document and drag to select the desired
range.

To extend or shorten a selection:

1. Make a selection with the mouse as explained
above.

Audio Info dialog

Selecting Audio Info from the Options menu (-I) – or
clicking on the Audio Info area – opens the Audio Info
dialog. The Audio Info dialog allows you to change the
sample rate, duration, root key (for use in a sample
playback instrument), and high and low key range. Note
that by changing the sample rate, the pitch and duration
of the audio will be affected. (To change the sample rate
of an audio document without changing the pitch, use
the Convert Sample Rate command from the DSP menu,
or click on the appropriate Toolbar icon.) The Audio Info
dialog is described in more detail later in this chapter, as
well as in Chapter 11: Menus.

2. Hold down the Shift key and click on the end of the
selection that you wish to modify.
3. Drag the mouse to extend or shorten the selection.
When you are satisfied with the length of the
selection, release the mouse.
To select audio between two markers:

1. Hold down the Command key () and click
anywhere in between two markers. (Markers are
explained in detail in the next section.) Peak selects
the audio between the markers.
2. If there are additional markers in the document
and you wish to extend the selection to encompass
other portions of audio that fall between the
markers, hold down the Shift key and the
Command key, and click between another two
markers. The selection will extend from the
originally selected audio to the audio that you just
added.

3. Repeat as desired to navigate to and select
additional audio between markers.
To select audio between two markers with the Tab key:

Selecting Audio
In order to perform any type of editing action on an
audio document, first you must select the portion of the
document that you wish to modify. Peak has several
techniques for making and modifying selections.

1. Create markers at several locations in the

Peak selects the portion of the waveform that lies
between the first two markers in the document.
3. Press the Tab key again to select the portion of audio
between the next two markers. (If you hold down the
Shift key while tabbing the selection through the audio
file, you can append each successive space between
markers to the current selection.)
4. Repeat as desired to navigate to and select
additional audio.

Auditioning Audio
It is often useful to audition a selection along with just a bit of
audio preceding or following it – without actually including this
material in the selection itself. Peak’s Auditioning command
allows you to do this by specifying a desired amount of pre-roll
or post-roll when you play the selection.
To audition audio with pre-roll or post-roll:

1. Choose Auditioning from the Preferences panel –
the Auditioning Preferences dialog appears.

To select all audio in a document:

•

Choose Select All from the Edit menu or press A on your Macintosh keyboard.

Markers & Selections as Navigational Aids

The presence of Regions, loops, or markers – and selected
portions of the waveform can be very helpful in navigating
through an audio document.
When markers are present, the Tab key on your keyboard may
be used to select the audio between markers. Pressing the Tab
key again selects the next space between markers – when Peak
reaches the end of the document, it will “wrap” back to the
beginning. Using the Option & Tab keys together will select the
spaces between markers in the opposite direction.
This keyboard shortcut makes it very easy to navigate to specific
areas, for example: Imagine you are working with a recording of
an LP, and have placed a marker in the space between each song
(the silent area). To quickly navigate to the beginning of song 5,
simply press the Tab key five times, and then press the up arrow
key on your keyboard – this would select the space between
markers that bound the fifth song, and the up arrow key would
locate Peak’s cursor to the beginning of the selection.

The Auditioning Preferences Dialog

2. Enter the desired amount of pre-roll and post-roll
and click OK.
3. Click the cursor in the audio document and drag to
select the desired range.
4. Press -Spacebar – Peak plays the selection,
adding the specified amount of pre- and post-roll.

Scrubbing
Peak offers a number of ways to scrub audio, these are
described below.
Dynamic Scrubbing

Many other useful tips can be found in Appendix
2: Peak Actions.
80

Peak provides a unique audio auditioning technique

Peak 5 User’s Guide

called dynamic scrubbing. This feature is very useful for
precisely pinpointing and selecting a desired location in
an audio document. Dynamic scrubbing allows you to
drag the mouse forward or backward over a waveform
while Peak plays a short loop (between 10 and 600
milliseconds) at the scrub location. When you have
found the location you are looking for, you can
commence editing. Peak allows you to choose the
length of this playback loop with the Dynamic Scrub
Time command in the Options menu. Peak provides two
types of dynamic scrubbing: dynamic shuttle scrubbing
and dynamic jog scrubbing. Both are described below.
To select a loop duration for dynamic scrubbing:

•

Choose Dynamic Scrub Time from the Options
menu, and choose a duration from the hierarchical
submenu. Typically, values between 40 and 80
milliseconds work well.

3. To make a selection starting at the current scrub
point, stop scrubbing, hold down the Shift key, and
click the mouse to extend the selection from the
insertion point to the desired end location.

Jog Scrubbing

Peak provides a variation of the dynamic scrubbing
feature, which is similar to a technique known in
recording studios as jog scrubbing. With this technique,
Peak actually engages playback and moves through the
file at its normal pace, but allows you to control the
playback point by dragging the mouse. You can control
the direction (forward or backward) of playback by
dragging the mouse forwards or backwards. This
scrubbing mode affords a greater degree of control when
you are “zoomed out” in the audio document window.
To use dynamic “jog” scrubbing:

1. Hold down the Control key and Option key and
drag the mouse across a portion of the waveform
in an audio document window. As you drag the
mouse, Peak engages playback while it loops a
short portion of the audio at the insertion point.
Dragging the cursor farther away from the current
insertion point increases the velocity of scrubbing.

Setting the Dynamic Scrub feature’s loop time

To use dynamic “Shuttle-type” scrubbing:

1. Hold down the Control key and click and drag the
mouse across a portion of the waveform in an
audio document window. As you drag the mouse,
Peak plays a short loop of the audio at the insertion
point. You can control the tempo and direction
(forward or backward) of playback by dragging the
mouse slower or faster, forwards, or backwards.
2. Release the mouse button to stop scrubbing. The
insertion point will be exactly where you left off
scrubbing.

2. Release the mouse button to stop scrubbing. The
insertion point will be exactly where you left off scrubbing.
3. To make a selection starting at the current scrub
point, stop scrubbing, hold down the Shift key, and
click the mouse to extend the selection from the
insertion point to the desired end location.
Since jog scrubbing mode is engaged by pressing the
Option key in combination with the Control key, it is
possible to toggle back and forth between jog and shuttle
modes simply by pressing or releasing the Option key.

Tape-Style Scrubbing

In addition to dynamic scrubbing feature, Peak provides
high resolution tape-style scrubbing. To enable tapestyle scrubbing, set the Dynamic Scrub Time under the
Options menu to Tape-Style.
To start tape-style scrubbing:

•

Hold down the Control key on your keyboard, and
then click and drag the mouse at the location in the
waveform where you wish to begin scrubbing.

To undo an action:

To deactivate tape-style scrubbing:

1. Perform an edit (such as cutting audio or moving a
marker).

•Release the mouse and Control key.
To control “tape” speed in tape-style scrubbing:

1. As you drag the mouse towards the right,
scrubbing speed will increase.
2. As you drag the mouse toward the left, scrubbing
will slow down.
3. If you drag the mouse to the left of the point where
you started scrubbing, the scrub direction will
change from forward playback to backwards
playback.
The top of the playhead cursor will display the scrubbing
speed, which can vary from +/- 2.25 times the original
speed.

Using Unlimited Undo and Redo
Peak maintains an internal list of the edits that you perform
during the course of an editing session. These changes are
not permanently applied to the file until you save it. This
82

gives Peak unlimited undo and redo capability. Through the
use of the Macintosh’s standard Undo (-Z) and Redo
(-Y) commands, you can undo and redo your actions
sequentially; or by using the Edits command, using a
“playlist-style” editing event list. This powerful capability
allows you to maintain complete creative freedom of choice
– right up until the last moment before you save your
project to disk. The only limitation in using Redo is that if
you insert a new action when a redo action is available, you
will no longer be able to redo. Remember, as soon as you
perform an editing action other than Undo in Peak, Redo is
no longer available.

2. Choose Undo from the Edit menu (-Z) or
Toolbar. The action is undone.
3. You can continue undoing actions until you return
to the original state of the audio document (the
state at which it was last saved). When there are no
actions left to undo, the Undo menu item will
appear grayed out.
To redo an action:

1. If you wish to redo the action that was undone,
choose Redo from the Edit menu (-Y ) or
Toolbar. The action is redone.
2. You can continue redoing actions until none are
left to redo. When there are no actions left to redo,
the Redo menu item will appear grayed out.

Using the Edits Command to Undo a Series of
Actions

Peak’s Edits command provides you with a second
unique and powerful method of undoing virtually

Peak 5 User’s Guide

any number of editing actions performed on an
audio document since you last saved it. You can
think of the Edits command as an “event-based”
listing of all your editing actions since you last
saved. Using this list, you can navigate back in
time to the point at which you performed a
particular edit, and if you wish, undo it. Once you
have returned to an earlier state in the project, you
are free to start editing from that point on.
The Edit history list is available in two locations –
one is in the Edits dialog, located under the Edit
menu.

Be aware that if you do go back to a past
action and perform a different action at that
state in the project, any edits that originally
occurred after will be gone, and you won’t be
able to redo them.

To use the Edits dialog to return to or undo an action:

1. Perform several edits. (Don’t use the Save
command or you won’t be able to undo any edits
that occurred before you saved.)
2. Choose Edits from the Edit menu. A dialog
appears listing the edits you have
performed since you last saved the
document.
3. In the list, double-click on the description of the
action you wish to return to (or select an action
and click the Revert to Item button). Peak returns
the document to the state it was in at the time of
that edit.

The Edits dialog

The other location where the Edit history may be
accessed is in the Audio Document Window’s
Contents Drawer.

Essential Editing Functions
Peak supports all of the Macintosh’s essential
editing functions such as cut, copy, and paste and
provides several more specifically designed for
audio editing. This section explains how to use
each of these functions.
Because Peak allows you to have multiple audio
documents open at the same time, it is possible to
conveniently cut, copy, paste, and insert audio between
documents. This makes combining material from several
audio documents very fast and easy.
Scratch Disks

Because audio data can be very large, Peak utilizes a
portion of your hard disk’s free space to hold audio data
that has been cut or copied, as well as for temporary or
“scratch” files for undo purposes. If you have more than
one hard drive attached to your Macintosh, the Scratch
Disks section of the Preferences panel allows you to
choose the hard drives (or “scratch disks”) that you wish
to use for these temporary files. Peak allows you to
select which disk you want to have as your default, or
“Primary” disk for this purpose – ideally you would
select the disk that has the most free space. If you are
connected to a file server, you can utilize available
storage on the server by clicking the Allow Servers
84

checkbox (that is if you have a very fast server
connection). Any available servers will then appear in
the Scratch Disks pop-up menu. This is recommended
only if you have access to a high-speed ethernet, or other
fast server.

Clearing the Clipboard to Reclaim Disk Space

If you no longer need the clipboard contents, you can
free up the disk space occupied by the clipboard by
choosing the Clear Clipboard command from the Edit
menu.

Cutting Audio

The Cut command (-X) allows you to cut a selected range out
of an audio document. Audio that occurs after the cut slides
over to fill in the gap. By cutting and pasting “pieces” of audio,
you can freely rearrange material in an audio document. This
can be a powerful tool for creating audio remixes for musicoriented applications, as well as an indispensable tool for general
sound design tasks. When you cut a selection, the Macintosh
holds the cut audio data in its internal memory (the Clipboard)
in case you wish to paste it elsewhere. Because all real-time
editing you do with Peak is nondestructive, the audio isn’t
actually removed from the original audio document until you
finally save the file to disk with the Save command. At that time,
all edits are saved and any changes that you have made are
permanently saved to the audio document.

Peak 5 User’s Guide

to freely rearrange material in a document. This
can be a powerful tool for creating audio remixes
for music-oriented applications, and is an
indispensable tool for sound design.

2. Choose Cut from the Edit menu (-X) or Toolbar.
3. The selected range is removed from the audio
document(s) and held on the Clipboard. Audio
occurring after the cut slides over to fill in the gap.

To copy a selection:

1. Click the cursor at the desired location in the audio
document and drag to select the desired range.
2. Choose Copy from the Edit menu (-C) or
Toolbar.

Deleting Audio

3. The selection is copied to the Clipboard.
If you wish to remove a section of audio from an audio
document without using the Cut command, you can use
the Delete key, or the Delete button on the Toolbar. As
with the Cut command and other editing functions, the
audio isn’t actually removed from the original audio
document until you save the file to disk.
To delete a selection:

At this point, you can use the Paste, Insert, or Duplicate
commands to place the copied audio into an audio
document. Each of these commands is explained below.

Pasting Audio

1. Click the cursor at the desired location in the audio
document and drag to select the desired range.
2. Press the Delete key, or click the Delete button on
the Toolbar.
3. The selection is removed from the audio
document. Audio occurring after the deleted
section slides over to fill in the gap.

Copying Audio

The Copy command ( -C) copies the current
selection to the Macintosh’s Clipboard (or internal
memory buffer) so that you can paste it, insert it,
or use it with optional “Clipboard-based”
processing such as Add, Convolve, Mix, Modulate,
and ImpulseVerb. As with the Cut command,
copying and pasting “pieces” of audio, allows you

The Paste command ( -V ) allows you to paste the
contents of the Clipboard into a location that you
choose by placing an insertion point. Pasting
audio deletes any selected audio and inserts the
clipboard audio at the insertion point. Blending
can be used with the Paste command if you have
made a selection – the pasted audio will be
crossfaded with the audio on either side of the
selection according to the Blending Envelope and
Blending Envelope Duration settings.
By cutting and pasting pieces of audio, you can
freely rearrange material in an audio document. In
musical applications, this gives you the freedom to
entirely “rewrite” compositions by changing the
order of things, repeating desired sections, and so
on. In sound design applications, this gives you
the power to “compose” with sound by creating
audio collages.

To paste audio into an audio document:

1. Click the cursor at the point where you wish to
paste the audio data in an audio document or make
a selection of audio you want to delete and replace
with the contents of the clipboard.
2. Choose Paste from the Edit menu (-V ) or
Toolbar.

The Clipboard contents are pasted into the audio
document(s), beginning immediately after the insertion
point. Any selected audio at the location of the paste is
overwritten when the pasted data is inserted into the
audio document.

To insert audio into an audio document:

1. Click the cursor at the point where you wish to
insert the audio data in an audio document.
2. Choose Insert from the Edit menu (-D) or
Toolbar. All data to the right of the insertion point
is pushed farther to the right (later in time) to
accommodate the newly pasted range.

Replacing Audio

The Replace command allows you to paste audio data
over existing audio – to paste audio into an audio
document without pushing all data to the right of the
insertion point farther to the right (later in time) to
accommodate the newly pasted audio. The Replace
command is useful for “laying over” a portion of audio
while maintaining the timing of the original document.
To replace audio into an audio document:

1. Click the cursor at the point where you wish to
replace the audio data in an audio document.
2. Choose Replace from the Edit menu or Toolbar. All
data to the right of the replaced audio maintains
their time position.

Inserting Audio

The Insert command (-D) allows you to paste audio
data into an audio document without overwriting any
86

existing data at the insertion point. When you paste data
with the Insert command, all data to the right of the
insertion point or selection start is pushed farther to the
right (later in time) to accommodate the newly pasted
audio. The Insert command is one of Peak’s most useful
tools for restructuring the contents of an audio
document. It is particularly good for “composing on the
fly” since it allows you to cut and insert pieces of audio –
musical phrases, riffs, or simply textural sounds – to
create a composition or soundscape.

Duplicating Audio

The Duplicate command has a number of different
behaviors, depending on whether you are working in an
audio document or in a Playlist. The behavior in Playlists
is covered in Chapter 6: Playlists – this section covers the
behaviors of the Duplicate command in audio
documents.
If no selection is made when this command is invoked,
the Duplicate command allows you to paste multiple
copies of audio data into an audio document without
overwriting any existing data at the insertion point.
When you paste data with the Duplicate command, all
data to the right of the insertion point or selection start
is pushed farther to the right (later in time) to
accommodate the newly pasted audio. The Duplicate
command allows you to specify how many times you
would like to Duplicate the audio data contained in the
clipboard. The Duplicate command is very useful for
creating longer audio documents that need to repeat a

selection for another duplicate of the full Clipboard
contents.

To Duplicate audio:

1. Select a range of audio, and choose Copy from the
Edit Menu (-C).
2. Click the cursor at the point you wish to insert
duplicate copies of the audio selected in step 1.
3. Choose Duplicate from the Edit menu.
4. Use the Duplicate slider to indicate how many
copies should be inserted, or type in the number of
desired copies.
5. Click the OK button. All data to the right of the
insertion point is pushed farther to the right (later
in time) to accommodate the newly pasted range.

If there is a selection in the waveform when the
Duplicate command is invoked, then Peak automatically
fills the selection with the Clipboard contents. Peak
determines how many times the Clipboard contents
must be duplicated in order to fill the selection. If the
selection is not evenly divisible by the duration of the
Clipboard contents, Peak includes a fraction of the
Clipboard contents to make the duplication completely
sample accurate to the original selection.
To Duplicate audio to fit a Selection:

Cropping a Selection

The Crop command (-`) allows you to make a
selection in an audio document and quickly remove all
other audio from the audio document except the
selection. The Crop command is a particularly useful
tool for editing material to be used as samples or sound
effects, since it allows you to isolate and save just the
desired portion of a recording.
To crop a selection:

1. Click the cursor at the desired location in the audio
document and drag to select the desired range.
2. Choose Crop from the Edit menu (-`). All audio

Silencing a Selection

To insert silence of a specific duration into a document:

The Silence command (-E) replaces the selected
portion of an audio document’s waveform with silence.
This feature is very useful for silencing nonessential
portions of a recording that contain an unusual amount
of noise. This can be used very successfully with spoken
material such as dialog or narration to remove noise
between words or during pauses in speech. It can also
be used to remove pops or clicks that occur in such
material.
To silence a selection:

1. Click the cursor at the desired location in the audio
document.
2. Choose Insert Silence from the Edit menu.
3. In the dialog that appears, enter the amount of
silence that you wish to insert into the audio
document – Peak inserts the specified amount of
silence into the document.

Repairing Clicks & Pops

1. Click the cursor at the desired location in the audio
document and drag to select the desired range.
2. Choose Silence from the Edit menu (-E) – the
selected audio is replaced with silence.

Inserting Silence into a Document

Clicks & pops are common artifacts in digital audio
– they occur in various ways, such as: performing
cut/copy/paste-type edits at non-zero crossings in
the audio waveform, recording vinyl records, faulty
recording equipment or cables, digital sync
problems, etc. There are two main categories of
clicks that Peak’s tools can repair.

The Insert Silence command allows you to insert a
specific amount of silence into an audio document
at the current insertion point. This feature is very
useful for inserting pauses of a desired duration
into a recording, and can be particularly useful in
adjusting the timing or rhythm of spoken material
such as dialog or narration. When you choose this
command, Peak will prompt you to enter the
amount of silence you wish to insert. You can
enter this value in samples, milliseconds, or
seconds. All audio occurring after the insertion
point is moved later in time by the amount of the
silence that you insert.

When editing audio with Peak, it is unlikely
that you will introduce new clicks and pops
because of its Auto Snap (to Zero) option.
When Auto Snap (to Zero) is turned on
(which it is by default), any selections made
are automatically snapped to the closest zero
crossing in the waveform, where the audio is
at zero amplitude. This ensures that you do
not inadvertently introduce a click or pop
when performing cut/copy/paste type edits.

Analog clicks – such as those found in digital
recordings of vinyl records – are caused by
scratches or other surface imperfections on a
record. This type of click usually appears in the
audio waveform as an abrupt, jagged anomaly.
The Insert Silence dialog

88

Peak 5 User’s Guide

Example of a digitized scratch on a vinyl record

Digital clicks are generally caused by digital sync
problems with audio hardware interfaces, bad digital
cables, or recording with improper buffer settings. This
type of click generally has a square shape to it.

3. From the Action menu, select Zoom to Sample
Level – you should now be able to see the
individual samples that make up the click.

Example of a digital click

Peak’s Pencil Tool can repair either type, though in
the case of digital clicks you may want to use the
Repair Click and Repair Clicks DSP tools, which are
specifically designed for this purpose (more
information on Repair Click and Repair Clicks is
available in Chapter 7: DSP).
In either case, to use the Pencil Tool, you must be
zoomed in to sample level (sample level being the
first zoom level at which you can see individual
audio samples) or beyond. Additional information
on settings for the Pencil Tool is available in
Chapter 3: Peak Basics.

4. In the tool area of the audio document window,
select the Pencil Tool.

5. Click into the waveform, and “draw” across the
anomaly, trying to approximate the shape of the
waveform on either side of the click. When you
have repaired the click, don’t forget to switch back
to the Arrow Cursor.

To repair a click with the Pencil Tool:

1. Locate a click in the audio waveform – it will
appear as an abrupt “spike”.
2. Place the insertion point/cursor directly over the
click.

click – having a marker in place makes it easy to
locate the click, should you lose your place.

Using Crossfades and Blending to
Smooth Edits
Blending is an automatic crossfade function with a usereditable envelope. Peak can apply blending to areas of an
audio document where they are modified by cutting,
deleting, pasting, or other editing processes in order to
smooth abrupt transitions between waveform amplitudes. It
can be very useful for creating a smooth transition between
edits that would otherwise sound too abrupt. If you are
going to edit (i.e., Cut, Paste, Delete, etc.) a document, you
may wish to enable blending to smooth things out a bit. You
can toggle blending on or off by clicking the Blend
enable/disable button in the audio document window, or by
pressing the Caps Lock key on your keyboard.

The Blending Enable/Disable button in the audio document window

When you enable the Show Edits command, Peak
indicates areas of an audio document that you have
edited by enclosing these areas with hatched lines.
This provides you with a convenient visual
reference to portions of the document that have
been affected by your editing actions. Once you
save a document, the edits are saved, and these
indicators will no longer appear.

point in an audio document. Fade ins/outs can be very
useful for smoothly fading in or out of an audio
document, or for fading out of one type of audio material
into another. Very short fade ins can also be useful for
smoothing or removing clicks and pops in a recording.

Creating and Using Markers

The next few pages describe in detail the various ways to
create markers – by dropping them “on the fly” during
playback, inserting them during recording with Notepad
Cues, defining them with the mouse when playback is
stopped, creating markers using the Threshold DSP
command, or using the Markers from Tempo command
to insert multiple markers at regular intervals. Of the
various ways to create markers, the mouse method is
perhaps the more precise. However, since it is possible
to fine tune the location of a marker at any time by
dragging it, (or by using the Edit Marker dialog,
explained later) all methods work equally well – the
method you choose to insert markers will depend largely
on the task at hand.

Peak has a very powerful set of features to control
the placement and modification of markers.
Markers are locations in an audio document that
you define as important. By marking specific
locations in a recording, you can navigate easily to
a location for selection, editing or playback
purposes.

Remember that if Auto Snap is enabled the
insertion point will snap to the nearest selected
Snap To unit. This will cause your marker to be
placed at the nearest Snap To unit when you use
the mouse to create or place a marker.

Markers can also be made into loops. Loops are
used to sustain or repeat a section of audio. They
can be used for material that you intend to transfer
to a sampler, or simply for playback within Peak
itself. Peak allows you to create one loop per audio

Once you have created a marker, you can assign or edit
the marker’s attributes in the Edit Marker dialog.
Double-click the triangular base of the marker to open
the Edit Marker dialog.

Marker Position

The Marker Position field allows you to move a
marker to a specific time location in an audio
document by entering the desired value. The popup menu to the right of this field allows you to
choose
a
time
format
(samples,
Minutes:Seconds:Miliseconds, etc.) for the value
that you enter in the Marker Position field.

The Edit Marker dialog

Marker, Loop Start, and Loop End
Text

You may wish to give markers meaningful names (up to 256
characters long) based on their locations in an audio document.
Peak gives markers default numeric names based on the name
of the audio document and the order in which the marker was
defined. To name or rename a marker, simply type the new
name in to the Text field of the Edit Marker dialog.

You can easily find any marker, Region, or loop
that you have named by simply typing the first few
letters of its name. For example, if you want to
locate a marker called “Solo,” just type the letters
“s”-“o”-“l”, and Peak will automatically scroll to
the marker called “Solo.” If you hit Enter or Return
after typing the characters, Peak will also
automatically place the insertion point at that
marker. If more than one marker matches the
letters you type in, Peak will locate the first marker
with that name. (Note that numerical marker
name entries will only work from the keypad, not
the numbers keys along the top of your keyboard.)

If you re-name the first marker in a document to
“1” – then all subsequent markers will be
automatically named “2”, “3”, “4”, and so on. You
can then quickly locate to the desired marker by
typing its number on the numeric keypad (the
numbers at the top of the keyboard serve another
purpose) and pressing Enter.

These three radio-style buttons allow you to define
whether the marker is a regular marker or a loop marker.
If you choose to designate the marker as loop marker,
you can define it as either the loop start or the loop end
by clicking on the corresponding radio button.
Anchor To Sample Checkbox

When you insert or delete audio that is near a marker,
you may want the marker to move with that particular
location on the waveform. This will compensate for the
insertion or deletion, so that the marker remains with
the particular portion of audio you want it to be
associated with. By enabling the Anchor feature for a
marker, you can assure that Peak will “tie” the marker to
a location on a waveform, causing it to stay with that
location even when audio is inserted or deleted into the
document. By default, Peak enables this feature for
markers, loops and Regions.
Be a Reference Marker Checkbox

By defining a marker as a reference marker, you can use the
marker as a reference when you make selections or move other
markers. Selecting or dragging the marker will then
automatically display the distance to the closest reference
marker in whatever time format (Samples or Seconds) is
currently selected in the Peak application. This may be useful,
for instance, if you know that you want a particular sound event
(such as a car door slam) to happen a certain number of seconds
before or after another sound event (such as a tire squeal).

Deleting Markers

Pressing the Return key first, and then typing
the marker’s name ensures that markers are
placed accurately – for instance, if an error
was made when typing in the marker’s name,
it might take longer than anticipated to enter
the corrected name, and the marker would
be placed later in time. By pressing the
Return key first, and then typing the name,
you can be sure that the marker is placed in
the correct location.

The Delete Marker button allows you to remove the
currently selected marker from an audio document.

To paste just the markers, you must hold down the
Option key and choose Paste from the Edit menu –
using the -V keyboard command will paste the
audio on the Clipboard, as well as the markers.

3. Type the name of the Region and click OK. The
new Region will appear in the audio document.
To modify the length of the Region by changing the start or end:

•

Drag the start or end marker of the Region in the
audio document window.

To move a Region without changing its length:

•

Regions
Regions are portions of an audio document defined by
Region Markers using the New Region command from
the Action menu (-Shift-R) or Toolbar. Regions
present in currently open audio documents will be listed
in the Contents window.
Regions can be saved only into AIFF, Sound Designer II, and
WAVE files. However, Peak will also read Regions stored from
other programs in Sound Designer II files. The method Peak
uses to store Regions in AIFF files is specific to Peak and is
not necessarily supported by other software applications. If
you are using Regions with other programs, you will want to
store your files as Sound Designer II or WAVE files.

Click the Horizontal Lock button in the tool area of
the audio document window, and then drag either
the start or end marker of the Region.

To edit a Region’s start, end, or length manually:

Double-click the Region’s name in the Contents
Window or in the audio document window’s
Contents Drawer. The Region will automatically
snap into view, with the Region selected.

To paste just the Region markers, you must hold
down the Option key and choose Paste from the
Edit menu – using the -V keyboard command
will paste the audio on the Clipboard, as well as
the Region markers.

or:
•

Type the first few letters of the Region’s name,
and the Region will snap into view automatically.
Please note that if multiple Regions share similar
names, such as “TheIntro” and “TheEnd”, you
would need to type at least one character
beyond “t-h-e-” for Peak to be able to distinguish
between these similar names. If you plan on
using this technique to locate to Regions, it is
recommended that you not use spaces in the
Regions’ names, as when you attempt to locate
to them, pressing the Space Bar on your
keyboard will initiate playback.

To split a Region:

1. Place insertion point cursor at the the desired
location.
2. Choose New Region Split (Ctrl-Shift--R) from the
Action menu. The cursor’s position determines
the split point. Any part of the document before
the split point becomes one Region, and any part
after the split point becomes another Region.

Creating Loops
If you’re editing music or other rhythmically-based
material, it is generally a good idea to test a
selection to make sure it contains an even number
of beats before you cut, copy, or paste it. A good
way to do this is to loop the selection and listen to
the loop as it plays. As described in the next
section, Peak includes Loop Surfer, which can
automate the process of finding a rhythmically
“correct” length of audio to loop, assuming you
know the tempo and the number of beats you wish
to loop. You can also use the Loop Tuner, found in
the DSP menu, to adjust the loop start and end
points. The Loop Tuner is also described in the
next section.
Loops are useful in material that you plan to transfer to a
sampler. Loop markers created with Peak are recognized
by samplers as sustain loops. Peak allows you to create
one loop per audio document.

Chapter 5: Editing

99

When using a single loop per audio document,
there is a quick and easy way to mark multiple
desired sections for looping. With the loop
markers in the desired location, choose Select
Loop from the Edit menu, then, choose New Region
from the Action menu – a Region is created that is
the same length as the loop. Using this technique
allows you to create as many Regions as desired
within a single audio document. To loop any of
these Regions, simply -click between a Region’s
markers to select the Region (or press the Tab key
until the desired Region is selected), and then
choose Loop this Selection from the Action menu.

To play a loop in Peak, select Use Loop in Playback
command (-L) from the Options menu or click the
loop button in the Transport window, begin playback,
and when Peak reaches the loop, it will continue to
repeat until you stop playback. If Use Loop in Playback
is not enabled, Peak will simply play right through the
loop to the end of the audio document or selection.
To create a loop from a selection:

1. Click the cursor at the desired location in the audio
document and drag to select the range you want.
2. Choose Loop This Selection from the Action menu
(-Shift-”-”) or Toolbar. Your selection is now
looped. Loop markers appear at the beginning and
end of the loop.
3. To listen to the loop, choose the Use Loop in
Playback command (-L) from the Options menu
(a check next to this menu item indicates it is
enabled), or click the Loop button in the Transport
window, and start playback by pressing the
Spacebar on your keyboard.
4. You can interactively fine-tune a loop by dragging
the loop start or end markers while loop playback
100

is engaged. As you drag a loop marker to a new
location, Peak will adjust the playback loop to
reflect the changes you make. You can also use the
Loop Tuner to call up a dialog that allows you to
visually fine tune the loop, and even play the loop
while adjusting it to listen to the changes.
To change regular markers into loop markers:

1. Create markers in an audio document.
2. Double-click on the triangular base of the marker
that you wish to define as the loop start point. The
Edit Marker dialog appears.
3. Click the Loop Start button and click OK. The
marker becomes a Loop Start marker.
4. Double-click on the triangular base of the marker
that you wish to define as the loop end point. The
Edit Marker dialog appears.
5. Click the Loop End button and click OK. The
marker becomes a Loop End marker. You have
now defined a loop in your audio document.
To move a pair of loop markers together:

•

Hold down the Option key and drag one of the
loop markers to the desired location. Both
markers move in tandem as you drag.

or:
•

Click the Horizontal Lock button in the audio
document window, and drag the begin loop or end
loop marker – both markers move in tandem. Be
sure to turn off Horizontal Lock to move the loop
markers independently.

To listen to the loop only:

1. Choose Select Loop (-”-”) from the Edit menu to
select the loop.
2. Make sure loop playback is enabled using the Use
Loop in Playback command (-L) from the
Options menu (a check next to this menu item
indicates it is enabled), or by pressing the Loop
button on the Transport.
3. Press the Spacebar to begin playing back the loop.

There are two ways to turn Use Loop in Playback on or off

2. Save the AIFF file – the loop flag is saved in the off
position.

Turn Loop Flag On/Off on Save

This feature allows the loop flag in AIFF files to be turned
on or off when saving a file. The state of this loop flag
when a file is saved determines the file’s playback
behavior when loaded into Peak again, or into another
application capable of reading embedded loop flags.
The loop flag is now toggled on or off when saving,
depending on the state of the Loop Playback setting in
Peak.
To Save an AIFF File with the Loop Flag On:

Crossfading Loops
Peak allows you to crossfade the start and end points of
a loop. Crossfading a loop can be very useful for
smoothing the transition between the end of the loop
and its beginning as it repeats. Peak allows you to
control the envelope of the crossfade, the duration, and
other parameters in the Crossfade Loop dialog.
The Crossfade Loop dialog

1. From the Options menu, choose Use Loop in
Playback (-L), or click the Use Loop in Playback
button in the Transport. A check next to the menu
item, or an illuminated button in the Transport
indicates the loop flag is turned on.
2. Save the AIFF file – the loop flag is saved in the on
position.

The four checkboxes at the top of the Crossfade Loop
dialog allow you to customize how the end of the loop is
faded into the beginning of the loop. These boxes
indicate where in the loop the crossfade is applied. For
most loops, you should be able to leave the default
checkbox checked and get good results.

To Save an AIFF File with the Loop Flag Off:

1. From the Options menu, choose Use Loop in
Playback (-L), or click the Use Loop in Playback
button in the Transport. The absence of a check
next to the menu item, or a non-illuminated button
in the Transport indicates the loop flag is turned
on.

Crossfade Variations

If you consider the crossfades “A”, “B”, “C”, and “D” from
left to right, then:
“A” =

Crossfade between A and C

“B” =

Crossfade between B and D

“C” =

Crossfade between C and A

“D” =

Crossfade between D and B
A

B

C

D

Another application that may require using loop
crossfade position(s) other than the default position “C”,
are when creating audio loops intended to be used in a
proprietary video game audio engine. Depending on the
requirements of a particular video game’s audio engine,
users may need to adjust the position of the crossfades
used in their loops, to achieve the desired effect.
Depending on the application requiring crossfades, users
may need “loop with release” (plays the tail of the audio
document – the section of audio that lies outside the
loop markers – after the loop stops playing/sampler’s
key is released) or “loop hold” (doesn’t play the audio
after the loop when the key is released). Because of
these different modes, users may need to turn some
crossfades on or off
To crossfade a loop:

1. Create a loop using one of the techniques
explained earlier in this chapter.
Crossfade positioning options – different uses for loops may call for
different loop crossfade settings – With crossfade position “C”
checked a crossfade is applied as indicated by the red “X”

Crossfade positioning options – different uses for loops
may call for different loop crossfade settings – With
position “C” checked, a crossfade is applied as indicated
by the red “X”
The way these crossfade variations are configured
depends on where the loop is destined to be used – for
most purposes the default crossfade position (Position
“C”) works well – if however, you plan on transferring
these loops to a sample playback instrument such as a
SMDI sampler, then you may want to experiment with
different crossfade positions/combinations. Some
hardware based samplers offer advanced playback
controls, allowing loops to be played forward, backward,
and in various other ways. By changing where in the loop
crossfades are applied, you can customize your audio
content for a particular sampler and for the desired
effect.

102

2. Choose Crossfade Loop from the DSP menu or
Toolbar.
3. In the Crossfade Loop dialog that appears, enter a
duration for the crossfade-in milliseconds and click
OK.
4. To hear the completed crossfade, choose Select
Loop from the Edit menu, select Use Loop in
Playback from the Options menu (-L) or click
the Loop button on the Transport, and press the
Spacebar. You will hear the loop, complete with
your crossfade.
To edit a Crossfade Loop Envelope:

4. Continue creating and dragging breakpoints until
you have created the envelope that you desire. If
you wish to delete a breakpoint, click on it with the
cursor and press the Delete key on your computer
keyboard.

Peak’s Loop Surfer feature automates some of the steps for
setting up loop points. Loop Surfer allows you to “Loop
Surf ” (adjust your loops during playback) quickly, easily
and in a musically intuitive manner.

5. If you wish to reverse the shape of the envelope
you have created, click the “<->” button. This
creates a mirror image of the envelope.
6. If you would like to save your custom envelope for
later use, click on the Save button before exiting
the envelope editor.
7. When you are satisfied with your new envelope
shape, click Change to confirm your edits and close
the envelope editor. Peak will use this envelope
until you change it again.

If you’re working with music, and know the music’s tempo in
beats per minute, you can use Loop Surfer to create a loop
which lasts for a rhythmically “correct” length of time.
To use Loop Surfer based on a musical tempo:

1. Place the cursor where you wish to begin the loop
(it’s okay to place it approximately, rather than
exactly, where you wish to start).
2. Choose Loop Surfer from the Action menu (-J).
The Loop Surfer dialog appears.

To hear the completed crossfade, choose Select Loop
from the Edit menu, select Use Loop in Playback from

3. Type in the music’s tempo. If you are not sure of
the tempo, you can use the Tempo Calculator to
determine the tempo. Simply select a portion of
audio, and type in the number of bars and beats in
the selection. The calculator will determine the
tempo based on your selection. If you are unsure,
and have used a drum machine or sequencer to
create the music, you might wish to refer back to
its settings determine the time signature and
tempo. Additionally, you can use the Threshold
command from the DSP menu to select a portion
of audio that should correspond to the beat; see
“To use Loop Surfer based on a selection” below.
4. Type in the number of beats that you wish the loop
to last. The beats are based upon quarter-notes, in
terms of musical time. For instance, if your song
was in a 4/4 time signature, typing “4” beats would
mean the loop would be one measure in length; if
the song were in 7/4 time, typing “14” would mean
the loop would be two measures in length. (If you
are interested in exploring syncopations, however,
there’s no reason why you can’t type a beat value
that doesn’t correspond to the time signature, such
as “5” if the music is actually in “3/4” time.)
5. If you then select the Start Surfing button (the
default), Peak will automatically:

104

a)

close the Loop Surfer dialog box;

b)

extend the selection from the cursor insertion
point to a calculated length, based upon the
tempo and number of beats;

c)

change the cursor insertion point to a Loop
Start marker;

d)

drop a Loop End marker at the end of the
newly calculated selection;

e)

turn on (if it hasn’t already been turned on)

the Use Loop In Playback option under the
Options menu.
f)

begin looped playback of the audio selection,
stopping only once you hit your keyboard’s
Spacebar or press Stop on the Toolbar.

6. If you select the Make Loop button, Peak will
automatically:
a)

close the Loop Surfer dialog box;

b)

extend the selection from the cursor insertion
point to a calculated length, based upon the
tempo and number of beats;

c)

change the cursor insertion point to a Loop
Start marker;

d)

drop a Loop End marker at the end of the
newly calculated selection;

e)

turn on (if it hasn’t already been turned on)
the Use Loop In Playback option under the
Options menu.

f)

At this point, you must start playback manually
using the Spacebar or the Toolbar if you wish
to begin Loop Surfing.

While you’re Loop Surfing (adjusting your loop during
playback), you’re free to perform all standard looping
functions as described in the previous section, including
adjusting the Loop Start and End points during playback.
Most importantly, you’ll now have a selection that lasts
for a rhythmically correct period of time (that matches
the beat). If you move the markers in tandem, by
holding down the Option key and clicking and dragging
one of the loop markers to the desired location with the
mouse, you’ll find it’s a great way to set up interesting
rhythms and syncopations! Peak’s interactive editing
capabilities also allow you to use the Loop Surfer dialog
while a loop plays to adjust the tempo, beats and so on.

Peak 5 User’s Guide

If you’re not working with music (or if you simply don’t
know the tempo of the music you’re working with), you
might choose to Loop Surf based upon a selection (or
use the Threshold feature), rather than starting at a
cursor insertion point.
To use Loop Surfer based on a selection:

2. Select Loop Surfer from the Action menu. The

Making Loops into Regions

1. Place the cursor where you wish to begin the loop,
and using the mouse, select the portion of audio
you wish to loop. ( You can make your selection in
a variety of other ways, also, as described earlier,
including selecting between markers by -clicking
with the mouse).

As you “Loop Surf ”, that is, as you move the loop points
simulatneously through an audio document while audio
plays, you may find sections that you would like to set
aside for later. These sections can be saved as Regions,
which can be used to create a remix within a Peak Playlist,
may be exported as new audio documents, or used in a
loop-based sequencing application, such as Ableton Live
or Apple SoundTrack or GarageBand.
Since Peak allows only one loop per audio document,
you can turn the loops that you like into Regions.
To create Regions from Loops:

a)

close the Loop Surfer dialog box;

b)

extend the selection from the cursor insertion
point to a calculated length, based upon the
tempo and number of beats;

c)

change the cursor insertion point to a Loop
Start marker;

d)

drop a Loop End marker at the end of the
newly calculated selection;

e)

turn on (if it hasn’t already been turned on)
the Use Loop In Playback option under the
Options menu;

f)

g)

begin looping and playing. The selection will
begin looped playback (if you have selected
Start Surfing);

1. As a loop plays, choose Select Loop (-”-”) from
the Edit menu.
2. With the loop selected, choose New Region (-R)
from the Action menu. Name the Region and click
OK.
3. Hold down the Option key (or click the Horizontal
Lock button in the Toolbar) and drag the begin
loop or end loop marker to a new position in the
audio document – both loop points will move
simultaneously.
4. When you locate another section of the audio
document that you would like to set aside for later
use, choose Select Loop (-”-”) from the Edit
menu.

You can also use the Threshold command (described in
greater detail in Chapter 7: DSP) to define a number of
markers or Regions based on amplitude peaks. If you
then select audio with start and end points that
correspond to these sections, you should have a
selection that precisely matches the musical beat. Using
Loop Surfer, you could then automate the process of
looping the selection by following the steps described
directly above.
Guess Tempo works best with audio selections that
contain one full measure of audio with pronounced
attacks on the beats, which appear visually on the
waveform as taller sections of the audio. Using the
Normalize feature on the selection prior to Guess Tempo
can improve the accuracy of its deduction.

Loop Surfer is not available in Peak LE.

LE
Using the Guess Tempo and
Threshold Commands to Find Tempo
If you are working with music and don’t know the tempo
– and your music has a relatively pronounced or obvious
beat – you can use the Guess Tempo command to have
Peak automatically guess the tempo of a selection. Make
a selection and choose Guess Tempo from the Action
menu. There will be a pause while Peak scans your
selection and calculates the tempo for you. A dialog will
then appear showing you the estimated tempo in BPM,
or beats per minute. You can then enter the estimated
tempo in BPM in the Loop Surfer dialog’s Tempo field or
in the Audio Information dialog’s Tempo field, or click
Loop-It to automatically place the guessed tempo value
into the Loop Surfer dialog.
As you Loop Surf, you may automatically change the
number of beats in a loop by selecting the loop (-Shift106

Guess Tempo is not available in Peak LE.

Using Loop Tuner
Peak’s Loop Tuner provides a way to visually line up the
start and end points of your loop to get a smooth
transition at the loop points. Loop Tuner also allows you
listen to the effects of these adjustments as you make
them. If you wish to “tune” a loop you’ve made, simply
select Loop Tuner from the DSP menu or Toolbar, and a
dialog will appear. The waveform display in the Loop
Tuner dialog shows the Start and End points of the loop,
which you can visually adjust with the scroll bars at the
bottom of the window. The two zoom buttons –
magnifying glass icons-in the upper left of the Loop
Tuner dialog allow you to adjust the vertical zoom up of
the waveform. The two zoom buttons in the lower left
hand corner of the Loop Tuner dialog allow you to adjust
the zoom view in and out all the way down to the sample

Chapter 6:
Playlists & CD Burning

Introduction
This chapter explains how to sequence Regions in a
Playlist document, and to create a “master” CD – from
which all subsequent copies are produced. Peak’s
Playlist allows non-destructive editing, crossfading,
setting custom gap times between tracks, applying
effects plug-ins, setting custom track start offsets,
embedding various types of metadata, such as
International Standard Recording Codes (ISRC), CDTEXT data, and much more.
A Playlist is a list of Regions strung together in a specific
order. Once Regions have been added to a Playlist, they
are referred to as Playlist Events. The Peak Playlist is a set
of instructions that tell the hard disk which Regions to
“read”, and in what order. Playlist editing does not
permanently alter the original audio data on your hard
disk. No matter how many changes you make, your
original recordings remain intact. This type of
nondestructive editing is one of Peak’s most significant
and powerful features.

from the hard disk (where the audio data is stored) from
any number of possible points originally designated by
Region markers, and these Regions can be auditioned in
the Playlist in any number of possible arrangements.
Playlist editing allows you to adjust and re-sequence
segments of audio (e.g., Regions) with ease. Edits can be
heard as soon as you perform them. In addition, Peak
allows you to apply unique effects settings to individual
playlist events. Peak’s Playlist offers a fast, flexible, and
powerful approach to editing and processing digital
audio.

A Region is defined by a set of Region Markers in the audio document window.

When editing in Peak’s Playlist window you are not
permanently deleting, moving, replacing, and adding
actual audio as you would if you were cutting and
splicing analog tape. Instead, Peak is creating a “map” of
your audio file. This map, or “playlist,” simply describes
the order in which you want portions of the recording to
be played. If you’d like to hear the middle of a song first,
the end next and the beginning last, you may arrange
your Regions in this order. Peak will read (e.g., play)

Peak’s Playlist allows you to output in many ways, from
burning audio CDs directly, to creating various file
formats used in the CD manufacturing process. Peak
burns fully Red Book compliant audio CDs from Playlists,
that will play in any CD-R compatible player. If you are
using Peak for commercial mastering, you will be pleased
to know that the master CD you create with Peak can
easily be used in mass duplication, and with an optional

extension package, Peak can also export a Playlist in DDP
(Disc Description Protocol), a format preferred over CD
by many duplication companies. You can also use Peak’s
Playlist to create a Jam Image file for burning audio CDs
using Roxio’s Jam™. You can also bounce (i.e., write to
disk) your Peak Playlist as a Sound Designer II file and
then import the Playlist Events as Regions into other
applications capable of reading Regions from SDII files.
Regions are covered in Chapter 5: Editing. Please
familiarize yourself with Regions before attempting to
work with Playlists. As Regions are the only items that
may be added to a Playlist, it is important to understand
how to create and edit them, before working with
Playlists.
The Playlist window is split into three main areas: The
Control Area, the Waveform View Area, and the List View
Area. This chapter will teach you how to quickly
assemble a Playlist and burn an audio CD, and then goes
over each of the Playlist’s three main sections in detail,
explaining each control, function, and mode.

most basic elements of working with Playlists. It is
recommended that you read this section before creating
any Playlist-based projects.
To Create a new Playlist:

1. From Peak’s File menu, choose New>Playlist
Document (-Shift-P) – an empty Playlist
document appears.

Adding Regions to a Playlist

There are a number of ways to add Regions to a Playlist
– here, we’ll use the Add Regions button. Information
on the other methods appears later in this chapter.
To Add a Region to a Playlist using the Add Region Button:

1. In the upper left portion of the Playlist interface,
click the Add Region Button – a pop-up menu
containing a list of all Regions in all open audio
documents appears.

Basic Playlist Concepts
This section deals with the basic hands-on aspects of
working with Peak Playlist documents. You will learn
how to create a Playlist, add Regions, perform edits, and
output a finished Playlist as an audio CD. Later in this
chapter, you will find detailed descriptions of the various
options.

Creating a Playlist

Before any Playlist operations can be performed, you will
need to open the audio documents containing the
Regions you wish to sequence, and a new Playlist
document must be created. This section goes over the

Selecting Playlist Events

To use the Move Event tool:

Once Regions have been added to a Playlist, they are
referred to as Playlist Events. Playlist Events will usually
need to be edited in some way. This editing may include
trimming, nudging, entering metadata, etc. Regardless
of the type of edit to be performed, it is important to
know how to make selections, as this is how particular
Playlist Events are targeted for editing processes.
To Select a Playlist Event in the Waveform View Area:

•

Click the desired Playlist Event – you will know it is
highlighted because it will appear in a different
color than other, unselected Playlist Events.
(Colors will vary depending on your color
preference settings).

1. In the Waveform Display Area, hover the mouse
cursor over the middle portion (i.e., not near the
edges), the cursor will be in Move Event mode, and
will look like this:

2. Click and hold the mouse button down, and drag
the Event left or right, to the desired position –
the Event moves to an earlier or later position in
the timeline.
To use the Trim Event tool:

1. In the Waveform Display Area, hover the mouse
cursor near the Begin or End Boundary of a Playlist
Event, the cursor will be in Trim Event mode, and
will look like this:

A selected Playlist Event appears in a different color than unselected
Events – by default, they appear in yellow

About the Move Event & Trim Event Cursor Modes

Many of the edits you will make in a Playlist will be done
using the Move Event and Trim Event tools. The cursor
switches between these two modes automatically,
depending on where the cursor is in relation to certain
parts of a Playlist Event’s Waveform representation.
When the mouse cursor is located over the waveform, it
is in Move Event mode. Clicking and dragging left or
right while in this mode will move the entire Event
earlier or later in the timeline. When the mouse cursor
is placed within a few pixels of the edge of a Playlist
Event’s Waveform display, it switches to Trim Event
mode, and can be used to trim or extend the Playlist
Event.

2. Click and hold the mouse button down, and drag
left or right – depending on whether you are
trimming the Begin or End Boundary, the Event is
either trimmed (shortened) or extended
(lengthened).

Deleting Playlist Events

Selected Playlist Events may be deleted in Waveform
View or in List View.
To Delete a Playlist Event:

•

Select the Playlist Event(s) you wish to delete in the
Waveform or List View areas, and click the Delete

Peak’s Playlist features unlimited levels of undo/redo. If
any mistakes are made along the way, they can easily be
undone. These steps show how to undo and redo edits
one at a time. More information about using the
graphical Edit History list appears later in this chapter.

To Crossfade Playlist Events in List View:

1. Locate two adjacent events you wish to crossfade
together in List View.
2. In the earlier (or “Out Event”) Event’s row, click in
the O-XF-T Column (or “Out Crossfade Time”) –
the field becomes editable.

To Undo Edits one at a time:

From the Edit menu, choose Undo, or press
Z on your keyboard.

-

To Redo Edits one at a time:

•

1. Locate two adjacent Events you wish to crossfade
together.
2. Click on the earlier (or “Out”) Event, and drag it (using
the Move Event tool) to the right (later in time), so an
overlap in time is created between the two Events.
(Or, click on the later (or “In”) Event, and drag it to the
left, or earlier in time, until an overlap is created.

Using Undo/Redo

•

To Crossfade Playlist events in Waveform View:

From the Edit menu, choose Redo, or press
-Y on your keyboard.

3. Enter an earlier value than the Start Time of the
following Event and press the Return key on your
keyboard (the value that appears in the following
Event’s Start Time Column).

Auditioning Transitions
Creating Transitions between Playlist Events

A variety of different types of transitions may be created
in the Playlist – we’ll be working with a crossfade in this
step. A crossfade is a transition in which two Events
overlap in time – that is, before the earlier Event ends,
the later Event has already started. In the area where the
two Events overlap, the earlier Event fades out, as the
later Event fades in. In a typical crossfade, the overall
volume level remains more or less constant, though Peak
offers many options, making it possible to achieve
practically any effect desired. More information about
other types of transitions is available later in this chapter.
Crossfades may be performed in either Waveform View
or List View.
118

Before committing to a crossfade or other transition, you
will probably want to audition it to ensure that it is the
right length, and that the two Playlist Events blend
together in the intended way. This step shows a simple
crossfade audition, though there are a number of
variations on how auditioning can be used. For more
information, please see the detailed overview of the
XFade Audition Controls, later in this chapter.
To Preview a crossfade:

•

Click the Audition XFade button (or press the X
key on your keyboard) – the crossfade plays from
beginning to end.

Burning an Audio CD

4. Insert a blank CD – the Burn button becomes
available.

Burning audio CDs is one of the most common ways to
output the contents of a Playlist. Provided that your
Playlist was made in Audio CD mode (i.e., with the Audio
CD Playlist checkbox checked), the resulting CD will
conform to the Red Book standard, and will be playable
in any CD player. Burning a CD not made in Audio CD
mode may play on a standard CD player, but this will
depend largely on the CD player’s capabilities. For
maximum compatibility, it is recommended to burn in
Audio CD mode. For more information, please review
the section on Audio CD mode which appears later in
this chapter.
To Burn an Audio CD from a Playlist:

5. Click the Burn button – the Playlist is burned to
CD.

Saving a Playlist

Playlist documents may be saved and recalled later.
These steps will teach you how to save a Playlist you are
working on. More information about opening, closing,
and saving Playlists appears later in this chapter.
To Save a Playlist:

1. With the Playlist window in the foreground, choose
Select All (-A) from the Edit menu.

1. With the Playlist window in the foreground, choose
Save from the File menu.

2. In the upper left portion of the Playlist interface,
click the Burn Playlist to Audio CD button – the

a name, choose a directory, and click the Save
button.

3. In the Burn Audio CD dialog, choose the desired
burning options.

Detailed Overview of Controls,
Modes, and Tools
The Playlist’s sophisticated editing controls allow you to
choose from a variety of editing tools, modes, and
behaviors. Most editing controls are found in a beveled
section of the interface, below the Counter Display, and
to the right of the Crossfade Audition controls. The
various editing controls are described in detail below.

the end of the List, they become the last few items. If
a number of Playlist Events are in the List, and you
wish to place the new Regions in a specific location
(i.e., between two other Playlist Events), drag the new
Regions over the Playlist Event that you wish them to
appear directly before, and release the mouse button.
The highlighted Playlist Event is pushed further down
the List (and later in time) to accommodate the new
Regions, which are placed before it in the same
chronological as in their original source document.

Undoing/Redoing

Peak’s Playlist features unlimited levels of undo/redo.
Before diving into the various editing tools, modes, and
options, it’s probably a good idea to learn how to use the
unlimited Undo/Redo features. This way, if any mistakes
are made along the way, they can easily be undone.
Undo or redo actions may be performed one at a time, or
by using Peak’s graphical edit history window.
To Undo Edits one at a time:

•

From the Edit menu, choose Undo, or press
Z on your keyboard.

Peak 5 User’s Guide

To Redo Edits one at a time:

•

From the Edit menu, choose Redo, or press
-Y on your keyboard.

With CD indexes in place, a listener can navigate to the
index location using the indexing controls on a
compatible CD player. Most CD players do not support
navigation using indexes.

To Undo a Series of Edits:

•

From the Edit menu, choose Undo repeatedly, or
press -Z on your keyboard repeatedly – until you
have undone the desired number of edits.

Or:
1. From the Edit menu, choose Edits – Peak’s
graphical edit history window appears.
2. Select the Edit/point in the project you wish to
return to.

Control Area
The Control Area, located in the upper portion of the
Playlist window, contains all global controls (those that
affect both the Waveform and List Views). This part of
the Playlist interface is always available, even when one of
the other portions of the interface is hidden. This
section covers the function of each parameter and
control in this part of the interface.

3. Click the Revert to Item button.

4. Click the Done button.

Be aware that if you undo a series of edits, and
then perform new edits, you will not be able to
return to the series of edits that were undone –
these edits will be replaced by the new edits in the
edit history list.

The Playlist Function Buttons are found in the upper left
portion of the Playlist interface, and include controls for
adding and deleting items from the Playlist, burning a
completed Playlist to CD, exporting a Playlist, and a
number of other controls.

audio CDs using Peak. Indexes are created by placing
Markers in the desired location within a source audio
document/Region that is used in a Playlist. Index
markers are not visible when working in the Playlist, but
are burned to CD. Indexes are commonly used on
classical music CDs, where a track may be relatively long
(i.e., 20 minutes or more), and indexes appear at various
intervals or points of interest, within a single CD track.

Synchronizing Playlist Events with Source Regions

Before working in a Playlist, Regions are created in an Audio Document...

Here are the same two Regions, after being added to a Playlist – and now known as Playlist Events...

If edits are made in the Playlist that affect the duration or content of a Playlist Event (with the Trim Event Tool or Scroll Regions Tool),
the edited Events may be synchronized with the original source Regions, which exist in an Audio Document...

Here we have the original source Regions in the Audio Document, after having been synchronized – note that the position of the
Region markers has been updated to reflect the trimmed Playlist Events.

Add Region Button

This control allows you to add any Regions from any
open audio documents to the Playlist. When clicked, a
pop-up menu appears with a list of all available Regions.
When a Region is picked from this menu, it is added to
the Playlist. When other items are present in the Playlist,
a newly added Region is added as the last Playlist Event.

Duplicate Playlist Event Button

This control duplicates the selected Playlist Event. This
is especially useful when creating remixes or working
with loops, as it offers an easy way to extend the duration
of the Playlist to meet a specific length requirement.

Butt to Previous Event End Button

This control “snaps” a selected Playlist Event’s Begin
Boundary to the End Boundary of the preceding Playlist
Event, creating a “butt” edit. When multiple Playlist
Events are selected, each one is butted with the Event
that appears before it in the timeline. Be aware that The
Butt to Previous Event End control overrides the
behaviors of both Slip and Shuffle editing modes, and
can alter the relationships between Playlist Events. More
information on this and other types of transitions is
available in both the Waveform and List View sections,
later in this chapter.

Synchronize Playlist Event to Region Button

This control synchronizes the position of Region markers
in a Playlist Event’s source audio document. By default,
Peak does not update the position of Region markers in
source audio documents when trim or scroll edits are
performed in the Playlist. When this command is used,
selected Playlist Events will have their corresponding
Region markers in their source audio documents
updated. This control is useful for users who perform
trim and scroll edits in the Playlist, and need to have the
original Regions in the source audio documents updated
to reflect these edits. Using the Synchronize Playlist
Event to Region command allows additional Playlists to
be created, based on edits made in a prior Playlist, and
also allows exporting Regions from original source
documents that are identical to those used in a Playlist.
Depending on the nature of your project, you may wish
to synchronize edits made to Playlist Events with the
source Regions in the source audio documents. If you
have made additional edits (i.e., trimming, Scroll
Regions, etc.) to Regions after they have been brought
into the Playlist, you can synchronize the positions of the
Region markers in the source audio documents in just a
few easy steps. By synchronizing, you can be sure that
the source Regions will correspond exactly with the
Playlist Events used in a Playlist-based project.
To Synchronize Playlist Events with Source Regions:

1. Select the Playlist Events you wish to synchronize
with their source Regions.
2. In the upper left portion of the Playlist, click the
Synchronize Playlist Event to Region button – the
Region markers in the source audio document(s)
are repositioned to reflect any additional edits that

brought into the current Playlist.
If you use the Synchronize Playlist Event to Region
command, be sure to save the source audio
documents containing the Regions that were
synchronized before quitting Peak. If you do not
do this, Region markers may not be in the
positions you expect when you open the audio
document at a later time.

Pre-Roll Amount Field

Audition XFade

Audition Loop

Post-Roll Amount Field

As mentioned earlier, there are a number of different
types of transitions that can be created between Playlist
Events. These include butt edits, crossfades, gaps, and
pauses. While the following controls are technically
designed for previewing crossfades, they can also be
used for previewing other types of transitions.
Previews can be made with or without a user-defined
amount of Pre- & Post-roll. Pre- & Post-roll are useful, as
they play a bit of audio material before and after the
transition being previewed, and help to put the
transition in context of the material that appears before
and after the transition. The user-defined amount of Pre& Post-roll are specified in the Pre- & Post-roll fields in
the XFade Audition control area.

Pre-roll Amount Field

This field allows adding a specific pre-roll value to
crossfade auditions. Whatever amount of pre-roll time is
entered in this field will be added to the overall crossfade
audition time. For example, when auditioning with a
pre-roll value of three seconds, you will hear three
seconds of the Out Event’s audio content prior to the
beginning of the crossfade.

Post-roll Amount Field

This field allows adding a specific post-roll value to
crossfade auditions. Whatever amount of post-roll time
is entered in this field will be added to the overall
crossfade audition time. For example, when auditioning
with a post-roll value of five seconds, you will hear five
seconds of the In Event’s audio content following the
end of the crossfade.
To Set Post-Roll Amount:

1. Double-click in the Post-Roll field to make it
editable.
2. Enter the desired value (in seconds), and press the
Return key on your keyboard.
When you create transitions between Playlist Events (i.e.,
crossfades, butt edits, gaps, or pauses), you will most
likely want to test them out before committing to
burning them to an audio CD. The Audition Pre- & PostRoll fields allow you to specify how much audio is
included before and after a transition that is being
auditioned. Having a bit of program material before and
after a transition is helpful, because it puts the transition
in context with the material that precedes and follows it.
Once a Pre- & Post-roll amount has been set, it is applied
when using the Audition Crossfade controls (these tools
are covered later in this chapter in the section called
“Previewing Transitions between Playlist Events”).

To Set Pre-Roll Amount:

1. Double-click in the Pre-Roll field to make it editable.
2. Enter the desired value (in seconds), and press the
Return key on your keyboard.

Peak 5 User’s Guide

Be aware that the Time Units format you have
chosen in the Nudge Amount Format Pop-Up Menu
(covered in the next section) also dictates the
format you will use when entering pre- and postroll values – if you have chosen to use Minutes,
Seconds, and Milliseconds (MM:SS:ms), as your
Time Unit of choice, be sure to enter a pre- or postroll value in this format. Likewise, if you have
chosen Samples as your preferred Time Unit
format, enter your pre- and post-roll values with
this format in mind.

type of crossfade auditioning you choose. For example,
engaging Audition Loop, and then clicking the Audition
Crossfade button will play both parts of the crossfade
transition (the In & Out Events) in loop mode. If preand post-roll values have been specified, the loop’s
length will increase to reflect these. The keyboard
equivalent for this control is the L key.
To activate Looping for Previews:

on your keyboard) – the “Out” portion of the
crossfade is soloed. When looping is active, the
Loop button is highlighted in blue.

To de-activate Looping for Previews:

•

Click the Loop Audition button again (or press the
L key again on your keyboard) – the “Out” portion
of the crossfade is soloed.

Slip Mode Button

Clicking the Slip Mode button puts the Playlist into Slip
Editing mode. In Slip editing mode, a selected Event (or
Events) moves independently of all other Playlist Events
– when multiple Events are selected the relationship
between selected Events remains intact, and the selected
group moves independently of all other Events. Slip
mode editing is used when it is important to move only
the selected Event(s), and not disturb the placement of
other Events relative to the Playlist’s timeline. The
keyboard equivalent for selecting Shuffle editing mode is
the tilde (~) (or S) key – pressing the tilde (or S) key on
your keyboard will toggle between Slip and Shuffle
editing modes.
Moving a selected Event or Events with the mouse while
in Slip Mode does not affect the position of preceding or
following unselected Regions relative to the timeline.

When moving an Event in Slip Mode, other Events do not move...

Slip/Shuffle Mode Controls

Slip and Shuffle mode are both invaluable to the editing
process, as there are situations where different behaviors
are required. For example, a selected Playlist Event (or
several selected Events) may need to be moved
independently of all other Events – this is ideal for using
Slip mode, as when you use Slip mode, only the selected
Events are moved. However, there may be other times
130

when after dozens of careful edits you realize that
something that occurs very early in the timeline may
need a change. By using Shuffle editing mode, you can
make the edit early on in the timeline, and have all
subsequent Playlist Events maintain their distance
relationships – if you have carefully set up crossfades,
gaps, etc., these will all be preserved, as all Events that
occur later in the timeline than the current edit move in
unison.

However, the Event’s In & Out Crossfade durations do change...

Peak 5 User’s Guide

Moving a selected Event or Events in Slip Mode does
affect the duration of the crossfades for the Out Event
directly preceding the first selected Event, and the In
Event directly following the last of the selected Events

Event is selected, the same holds true for the Out Event
directly preceding it, and the In Event directly following
it).
The behaviors above hold true for all Playlist Event
movements made using the mouse. A number of
variations are available when moving Events using the

Nudge Controls

Nudging allows a user-defined amount of Playlist Event
movement, per click of one of the four Nudge buttons.

just above the Waveform View Area control the following
movements:

When a single Playlist Event is selected, the selected
crossfade is the one that occurs between it and the
Playlist Event that appears just before it in the timeline.

You may also find it handy to use the keyboard

Comma (or <)

•

Nudge “Out Event” Later in timeline = Shift +
Period (or >)

•

Nudge “In Event” Earlier in timeline = Comma (or <)

•

Nudge “In Event” Later in timeline = (or >)

It is important to understand that a crossfade is made up
of two component Playlist Events. The one that is being
faded out of is referred to as the “Out Event”, and the
one being faded into is the “In Event”. When using the
132

nudge buttons, keep in mind that each crossfade is
considered a group, made up of the In and Out Events
being blended together. As such, it is important to
understand that when nudging a crossfade’s two
components, you will always want to select the In Event.
A crossfade is said to be “selected” when its “In” portion
is selected. When multiple Events are selected, the
earliest one (in terms of position along the timeline) is
said to be a part of the selected crossfade – or, to be
more precise, its In Event is part of the selected
crossfade.

When multiple Playlist Events are selected, the selected
crossfade is the one that occurs between the earliest
selected Event and the Event that appears just before it
in the timeline.

When multiple Regions are selected, the earliest selected “In” Region
defines which crossfade is considered to be “selected”

Playlist Events may also be nudged when they are not
part of a crossfade with another Playlist Event. When
nudging an Event in this scenario, it must be selected,

Peak 5 User’s Guide

and only the Nudge In Event buttons should be used.
Using the Nudge Out buttons in this scenario results in
moving the Event that occurs just before the selected
Event.
The Playlist’s Nudge Controls are used for fine-tuning the
position of Regions relative to each other, as well as to
the Playlist’s timeline. In many cases, by nudging the
Events that are being crossfaded together, you may also
be altering the duration of the crossfade.
A number of the nudge controls and behaviors are userconfigurable, allowing users to nudge an Event by any
amount desired, using any of Peak’s available Time Units
measurements. For example, if a user is working on a
Playlist destined to become an audio CD, perhaps they
need to nudge by Seconds or CD Frames – if they are
working on a Playlist that combines dozens of very short
sound effects destined for use in the next big video
game, perhaps they need to nudge using Samples as the
Time Unit of choice.
There are two sets of Nudge buttons – one is used for
nudging the “In Event” (in a crossfade, the Event that’s
being faded into), and the other is used for nudging the
“Out Event” (in a crossfade, the Event that’s being faded
out of ). The Nudge controls exhibit a variety of different
functions that allow a selected Event or group of Events
to be moved by precise amounts.
The behavior of the Nudge controls will vary depending
on whether you are using Slip or Shuffle editing mode
(described in the previous section). Generally, when you
nudge regions in Slip mode, you are editing just the
position of the two Events that make up a given
crossfade. When you nudge the same Events in Shuffle
mode, you are editing the Events in the given crossfade,
and all the Events that occur after the In Events (in the
given crossfade) are locked to the In Event’s movements,
preserving the relationships between the In Event and all
subsequent Events. In this scenario, the In Event and all
the Events that follow it may move relative to the
timeline, but will not move relative to each other.

Nudge Out Event Earlier in Timeline

This control nudges the Out Event of a crossfade toward
the beginning of the Playlist’s timeline, or earlier in time.
To nudge an Out Event, the crossfade’s counterpart In
Event must be selected. The keyboard equivalent for the
Nudge Out Event Earlier in Timeline control is pressing
the Shift key + Comma key together.

An easy way to remember this keyboard shortcut is
that the Comma key is shared with the < symbol,
which indicates the direction that a Region will
actually be nudged.

In Slip editing mode, the Nudge Out Event Earlier in
Timeline button will move only the Out Event of the
selected crossfade. It shortens the crossfade duration of
the selected crossfade, and lengthens the duration of the
preceding crossfade, as the Out Event is “slipping” along
toward the beginning of the timeline, while all other
elements remain locked to it.
If multiple Events are selected, only the Out Event of the
selected crossafade (ie, the Out Event preceding the
selected In Events) will be nudged.
In Shuffle editing mode, the Nudge Out Event Earlier in
Timeline button will move both the In and Out Events
that comprise the selected crossfade. The duration of
this crossfade is maintained, as are the durations of all
subsequent crossfades – as they are all “shuffled” in
unison, being pulled toward the beginning of the
timeline. The duration of the preceding crossfade is
lengthened.

Before nudging – note that the “In” Region is selected, and that its
position does not move relative to the timeline

The “Out” Region moves to an earlier point in the timeline

If multiple Events are selected, the Out Event preceding
the first of the selected Events will be nudged – the In
Event and all subsequent Events will be nudged by an
equal amount, preserving the relationships between all
Events that follow in the entire Playlist.
The “Out” Region moves to a later point in the timeline

Nudge Out Event Later in Timeline

This control nudges the Out Event of a crossfade toward
the end of the Playlist’s timeline, or later in time. To
nudge an Out Event, the crossfade’s counterpart In
Event must be selected. The keyboard equivalent for the
Nudge Out Event Earlier in Timeline control is pressing
the Shift key + Period key together.

An easy way to remember this keyboard shortcut is
that the Period key is shared with the > symbol,
which indicates the direction that an Event will
actually be nudged.

In Slip editing mode, the Nudge Out Event Later in
Timeline button will move only the Out Event of the
selected crossfade. It lengthens the crossfade duration
of the selected crossfade, as and shortens the duration of
the preceding crossfade, as the Out Event is “slipping”
along toward the end of the timeline, while all other
elements remain locked to it.

134

If multiple Events are selected, only the Out Event
preceding the first of the selected Events will be nudged.
In Shuffle editing mode, the Nudge Out Event Earlier in

this crossfade is maintained, as are the durations of all
subsequent crossfades – as they are all “shuffled” in
unison, being pushed toward the end of the timeline.
The duration of the preceding crossfade is shortened.
If multiple Events are selected, the Out Event preceding
the first of the selected Events will be nudged – the In
Event and all subsequent Events will be nudged by an
equal amount, preserving the relationships between all
Events that follow in the entire Playlist.

Nudge In Event Earlier in Timeline

This control nudges the In Event of a crossfade toward
the beginning of the Playlist’s timeline, or earlier in time.

To nudge an In Event, it must be selected. The keyboard
equivalent for the Nudge In Event Earlier in Timeline

Peak 5 User’s Guide

When using the Playlist’s Nudge buttons to fine-tune the
position of a Playlist Event(s), you can specify how small
or large an increment each click of the button will move
the selected Playlist Event(s). In addition, you can also
choose the Time Units format used. Generally, you will
want to use a format that suits the type of audio project
you are working on. For example, if you are mastering an
audio CD, you will probably want to be working in
Minutes:Seconds:Milliseconds (MM:SS:ms) or CD
Frames – if you are working on the soundtrack for a
digital video project, you will probably want to work in
SMPTE units).
Nudge Amount Field

The Nudge Amount field lets you specify how many Time
Units to nudge an Event by, when using the four nudge
buttons mentioned above. For example, if you had the
Playlist’s Nudge Format set to Seconds, and you wanted
to nudge Events by one second with each click of a
nudge button, you would enter “1”.

Mode Checkboxes & Behaviors
Preserve Timing Mode Checkbox
Scroll Regions Mode Checkbox
Audio CD Playlist Mode Checkbox

Preserve Timing Mode Checkbox

Checking the Preserve Timing mode checkbox allows you
to move a crossfade’s location relative to the timeline,
without changing its overall duration. When using
Preserve Timing mode, the position of the In and Out
Events in question does not change relative to the
timeline, only the crossfade’s position moves. When the
Preserve Timing checkbox is checked, any Event
trimming will always extend the other component Event’s
boundary. You may temporarily toggle the Playlist into
Preserve Timing mode by holding down the Option key
on your keyboard, when the tool cursor is in Trim Event
mode. If the Preserve Timing mode checkbox is checked,
holding down the Option key has no effect.

To Set a nudge amount:

•

Click into the Nudge Amount field, and edit the
existing value (or double-click to enter a
completely new value).

Nudge Format Pop-Up Menu

The Nudge Format lets you specify what type of Time
Units should be used when nudging. Time formats
available include Samples, Minutes:Seconds:Milliseconds
(MM:SS:ms), SMPTE (24, 25, 29.97, 30, 59.97, and 60 fps),
Bars/Beats, and CD Frames.

Preserve Timing allows you to fine-tune the location of a
crossfade, and keep the overall duration of the two
component Events that are being crossfaded constant.
When trimming one component Event of a crossfade
with Preserve Timing mode engaged, the other
component Event is “untrimmed” by an equal amount.
The end result is that you are able to “slide” the crossfade
over both component Events simultaneously. By doing
this, you keep the audio content of both Events locked to
the timeline, and you preserve the duration and
envelope characteristics of the crossfade.

To Set a nudge format:

•

From the Time Units pop-up menu, choose the
desired Time Units format.
In this example, you can see the effect of trimming one of the component
Events that make up a crossfade transition. Vertical arrows point out
specific waveform events, which do not move relative to the timeline.

Chapter 6: Playlists & CD Burning

The beginning of the “Out” Event, and the end of the
“In” Event do not change position when editing in
Preserve Timing mode.

To move a crossfade while preserving its duration:

1. Create a crossfade between two Playlist Events.
2. Place a check in the Preserve Timing checkbox (or
hold down the Option key to temporarily toggle
into Preserve Timing mode.
3. Trim one of the component Events that makes up
the crossfade – the other component Event is
trimmed/extended by an equal amount.

Only the crossfade moves relative to the timeline, its duration remains intact,
and the audio content of the two Events does not move relative to the timeline
– the Playlist’s overall duration/timing is not altered. Vertical arrows point out
specific waveform events, which do not move relative to the timeline.

Scroll Regions Mode Checkbox

In Preserve Timing mode, when you edit a crossfade’s
position, you are essentially trimming one component of
a crossfade, and simultaneously extending (or
“untrimming”) the crossfade’s other component Region.
This has the overall effect of shortening one of the
component Regions, lengthening the other by an equal
amount, and maintaining the overall duration, or timing
of the entire Playlist.
Preserve Timing mode is especially useful when
compositing different recording takes together, or when
trying to locate the ideal crossfade position when working
with material that needs to have its tempo maintained,
such as electronic music with a constant tempo.
To engage Preserve Timing mode:

•

Check the Preserve Timing checkbox – the
presence of a check means Preserve Timing mode
is active.

To temporarily engage Preserve Timing mode:

•

138

Hold down the Option key on your keyboard while
trimming one component Event that makes up a
crossfade.

Checking the Scroll Regions Mode checkbox allows you
to scroll the audio content within fixed Playlist Event
boundaries. When the Scroll Regions mode checkbox is
checked, any use of the Move Event Tool will scroll a
Playlist Event’s content, keeping its beginning and end
boundaries locked to the timeline. To temporarily toggle
into Scroll Regions mode, hold down the Option key on
your keyboard while attempting to use the Move Event
Tool, rather than moving the Event, you will scroll its
content. If the Scroll Regions mode checkbox is
checked, holding down the Option key has no effect.
Scroll Regions is another mode which can also preserve
the overall duration of a Playlist. It allows you to keep the
beginning and end boundaries of a Playlsit Event locked
in place, and to vary the audio content that appears in the
“window” between them. Since the beginning and end of
the Playlist Event do not move relative to the timeline, the
Playlist’s duration does not change.
If a Region in a source audio document is equal to the
length of the entire document, you will not be able to use
Scroll Regions mode within the Playlist, as there is no
other audio content to scroll. This feature requires that
there be additional audio content outside the Region
markers in the source audio document. If a Region in a
source audio document is shorter that the document
itself, then you can scroll the Region’s audio content
within the Playlist.

Peak 5 User’s Guide

To engage Scroll Regions Mode:

•

Click the Scroll Regions checkbox – the presence
of a check means Scroll Regions mode is active.

To temporarily engage Scroll Regions mode:

•

Hold down the Option key on your keyboard while
clicking and dragging a Playlist Event (using the
Move Event tool) – the source Region’s content is
scrolled within the fixed Begin/End Boundaries.

To use Scroll Regions Mode:

1. Place a check in the Scroll Regions checkbox (or
hold down the Option key to temporarily toggle
into Scroll Regions mode.
2. Select a Playlist Event (or multiple Events).
3. Click over the selected Playlist Event’s Waveform,
and (with the Move Event tool) drag to the left or
right – the Waveform moves, while the Playlist
Event’s boundaries stay in a fixed location relative
to the timeline. (If scrolling the content of
multiple selected Playlist Events, it does not matter

which you click and drag in, as all selected items
will scroll an equal amount.

If a Region in a source audio document is equal to
the length of the entire document, you will not be
able to use Scroll Regions mode within the Playlist,
as there is no audio content outside the Region,
into which you can scroll. This feature requires
that there be additional audio content outside the
Region markers in the source audio document. If
a Region in a source audio document is shorter
that the document itself, then you can scroll the
Region’s audio content within the Playlist.

Audio CD Checkbox

When working with a Playlist destined to become a Red
Book audio CD, this box should be checked. When the
Audio CD checkbox is checked, the Playlist enters a
special Red Book compliant mode, which ensures that
any CDs burned from it will be Red Book compliant as
well. When this box is checked, a two second gap is
automatically placed at the beginning of the timeline,
edits are automatically “snapped” to CD frame

In this example, you can see the effect of scrolling the audio content within the fixed Begin/End boundaries of a Region...

Note that the Region’s Begin/End boundaries have not moved relative to the timeline – so the overall duration of the Playlist is maintained.

boundaries, and if the material contained in a Playlist
exceeds 74 minutes, the Program Duration display turns
red to alert you of a Red Book standard violation. Audio
CDs created in this mode will be compatible in any CD-R
compatible player. Note that high-resolution (i.e., higher
than 16-bit/44.1kHz) Playlists will be automatically
dithered and sample rate converted to 16-bit/44.1kHz
when burning an audio CD or exporting as a new file.
To engage Audio CD Mode:

•

Check the Audio CD checkbox.

2. Enter the desired metadata, and click OK – this
disc-specific information will be included when the
Playlist is burned to CD.

In addition to requiring Mac OS X v.10.4 or later to burn
CD-TEXT, ISRC codes, and subcode metadata, your
Macintosh must also have a CD burner capable of
burning this type of data. You may want to check with
your CD burner’s manufacturer to find out about what
types of data is capable of burning, or you can use a
handy UNIX command in the Terminal utility. The
Terminal application is located in the Utilities folder,
within the Applications folder.
To check your CD burner’s compatibility with the Terminal:

Longer audio CDs (usually up to about 79
minutes) may also be created when using the
Playlist in standard mode (i.e., not in Audio CD
mode). Many modern CD players can play audio
CD-Rs that violate the 74-minute limitation of the
Red Book standard, as long as all other Red Book
guidelines are observed. Keep in mind, that audio
CD-Rs longer than 74 minutes, created in
standard mode may not play on all CD players,
and cannot be used as pre-masters.

1. Open the Terminal application (from /Macintosh
HD/Applications/Utilities/)
2. At the $ prompt, type: “drutil info” and press
Return – you will see something that looks like
this:

The “CD-Write” category displayed will show the capabilities of the CD
burner in question. The CD burner used in this example is capable of
burning CD-TEXT, Index Points, and ISRC codes.

Adding Disc-Specific CD-TEXT Metadata

Various types of disc-specific metadata may be added to
Playlist project, and will be added to CDs burned from it.
These types of metadata include Disc Title, Performer,
Songwriter, Composer, Arranger, Message, Genre, Disc
Identifier, MCN (EAN or UPC), etc.

Being able to vary your view of Events along the Playlist’s
timeline is very important. There may be times when
you need the perspective of being zoomed out all the
way, so as to get an overview of how imported Regions
are arranged. Some kinds of edits may require the
precision of a high zoom level, so as to align the beats in
the waveforms of two Events you are trying to beatmatch. The following few steps, along with the section

Waveform Display Area

The Playlist’s Waveform Display area contains quite a
number of visual elements which are important to
understand. This section will familiarize you with these
elements, the majority of which will be used in every
Playlist project you undertake.

Playlist Event Display

The Playlist Event Display shows audio that is contained
between Region markers in the original source audio
document. By default, a Playlist Event appears in blue,
and when selected, in yellow. These colors may vary,
depending on whether you have assigned custom
themes or colors in Peak’s Preference Panel.

Playlist Event Name Display

The Playlist Event Name display appears in the upper left
corner of the Playlist Event Display. If a Playlist Event’s
Display is moved partially off-screen because of window
scrolling activity, the Event’s name will remain in view as
long as any portion of the actual Region Display is visible.
When a Track Offset is set, the Region Name Display
position defaults to the Offset’s position. If the Offset’s
position is moved partially off-screen due to window
scrolling, the Event Name Display remains visible, even
when the Offset itself is no longer visible.

Playlist Event Begin Boundary

The Playlist Event Begin Boundary is essentially the
beginning of a Playlist Event, or, the Playlist Event’s
earliest point along the timeline. A Playlist Event’s Begin
Boundary may vary depending on many factors, such as
trimming, moving, or nudging of the Event. A Playlist
Event’s Begin Boundary also serves as the default
position of a CD track index, when working with a Playlist
destined to be burned as an audio CD.

When a custom Track Start Offset is set for a
particular Event, it becomes the CD track index
for that Event.

When using the crossfade audition controls, the Begin
Event boundary serves as the audition starting point, and
when auditioning with pre-roll, is the point from which a
pre-roll amount is measured.

The Playlist Event End Boundary is essentially the end of
a Playlist Event, or, the Playlist Event’s latest point along
the timeline. A Playlist Event’s End Boundary may vary
depending on many factors, such as trimming, moving,
or nudging of the Event. Note that when burning to CD,
or exporting the Playlist as a file, that the end boundary
of one Event is the beginning boundary of the next
Event, so silent gaps are added to the end of the earlier
track, and extend its duration.
When using the crossfade audition controls, the End
Event boundary serves as the audition ending point, and
when auditioning with post-roll, is the point from which
a post-roll amount is measured.

Event’s Begin Time is also the default start time of a CD
track, when working with a Playlist destined to be burned
as an audio CD, and no custom Track Offset has been set.

Double-clicking the envelope opens the Event Crossfade
Out editor, where you may select a new envelope shape,
or create your own custom envelope shape. The
envelope shape dictates the audio’s amplitude level over
time. A steeper slope creates a more rapid change in
amplitude, and a more gradual slope creates a fade out
with a slower change in amplitude.

Crossfade In Envelope

A Playlist Event’s Crossfade In Envelope appears when
there is an overlap in time between the selected In Event
and the preceding Out Event. The Crossfade In
Envelope extends upwards and inwards from the lower
left corner of the Event Display toward the middle of the
Event. This part of the display also shows the envelope
shape – slow in, fast in, etc.

Crossfade In Duration

A Playlist Event’s Crossfade In duration may optionally be
displayed by selecting Show Marker Times from Peak’s
Options menu. When this option is enabled, a Playlist
Event’s Crossfade In duration is displayed directly below
the Event Name Display when the Event is selected. This
is a live display, and updates in real time when the Event
is being moved.

Crossfade Out Duration

A Playlist Event’s Crossfade Out duration may optionally
be displayed by selecting Show Marker Times from
Peak’s Options menu. When this option is enabled, a
Playlist Event’s Crossfade Out duration is displayed
directly below the Event Name Display when the Event is
selected. This is a live display, and updates in real time

Track Start Offset Indicator

Track Start Offsets are used when a different time than an
Event’s Begin Time needs to be used as a CD track index.
The Track Start Offset appears by default in the exact
same position as an Event’s Begin Boundary, and is
represented by a bold white line that overlaps the Event’s
Begin Boundary. When a Track Start Offset is used, it
becomes the CD Track index for the Event it is set for. A
custom Track Offset may be created by dragging this
indicator to a position earlier or later than the Event’s
Begin Boundary. The offset created is represented by a
shaded area that appears directly before or after the
Event’s Begin Boundary.

Track Start Offset Indicator

Pause/Gap Indicator

When setting a Track Start Offset or Pause/Gap, be sure to click and
drag the thick portion of the indicator, as shown above

Offset duration is displayed just to the right of the Offset,
and is indicated with a delta (Δ), and a positive or
negative time value, depending on whether the Offset is
created before or after the Event’s actual Begin
Boundary.

Gap/Pause Indicator

Gaps and Pauses are used to create silent gaps between
CD tracks – or to create pauses between CD tracks that
contain audio. By default, this indicator appears in the
same position as a Playlist Event’s Begin Boundary and
Track Start Offset. A custom Gap/Pause may be created
by dragging this indicator to a position earlier or later
than the Event’s Begin Boundary. The Gap/Pause is
represented by a shaded area that appears directly before
or after the Event’s Begin Boundary.
A typical use for a Gap is having two seconds or so of
silence between two CD tracks. A common use for a
Pause containing audio is in creating an audio CD of a
live recording, where the audience applause between
songs is placed in the pause – in this scenario, if a
listener advances to this CD track, they can skip over the
applause and go right to the song, but if they listen to the
CD from beginning to end, they would hear the applause
between songs.

marked at major time intervals. These marked intervals
will vary depending on the Time Units you have chosen
to use, and also depending on the zoom level you are
using to view the Waveform View Area. For example, if
you have chosen to use Minutes:Seconds:milliseconds as
your Time Unit format, and you have zoomed all the way
out, you will see the Timeline marked at one minute
intervals. As you zoom in, you will see the Timeline
marked at intervals of several seconds, and when
zoomed in all the way, the intervals appear every second.

Playhead Cursor

The Playhead Cursor indicates which portion of the
Playlist is currently being played back. Its position
corresponds to the numerical position indicated by the
Counter Display. Clicking anywhere along the Timeline
moves the Playhead Cursor to that location, and starts
playback.

Horizontal Scrollbar

The Horizontal Scrollbar is the bottom-most graphical
element of the Waveform View Area, and appears only
when there is more graphical content than can be
displayed on-screen at the current zoom level. This
control is used for changing the view only, and does not
actually move Events or other Playlist elements relative
to the timeline or to each other. The keyboard
equivalent for the horizontal scrollbar is pressing the
Control key and the Left or Right Arrow keys – Press
Control + Left Arrow to scroll to the left, or earlier in the
timeline, or press Control + Right Arrow to scroll to the
right, or later in the timeline.

The Timeline provides a reference as to where Playlist
Events exist in relation to the beginning of the timeline
(time zero). The Timeline appears horizontally along the

or backward in the Playlist’s timeline with the mouse. It
is represented by a <-> cursor. The keyboard
equivalents for the Move Event tool are the Comma and
Period keys (Comma moves an Event earlier in time,
Period moves it later in time) – these are the same as the
Nudge In Event keyboard commands, though using the
key commands moves/nudges an In Event by the amount

waveform – the cursor appears as a <->.
2. Click on the waveform – you can now drag the
Event to a new position, earlier or later in the
timeline.

Cursor Modes/Tools

Trim Event Tool

The Playlist automatically switches between its two
cursor modes, depending on the location of the cursor
relative to a Playlist Event’s Begin and End Boundaries.
When the cursor is positioned near one of the
Boundaries, it changes to the Trim Event tool, and when
it is positioned over the Waveform Display portion of an
Event, it changes to the Move Event tool. Aside from
positioning the cursor, no user interaction is required.

Move Region Tool Cursor

Trim Region Tool Cursor

The Trim Event tool trims the begin or end boundary of
the Playlist Event the mouse cursor is placed over.
Trimming (extending) the begin boundary of a Playlist
Event to the left, gives that Event an earlier start time in
the timeline and extends the duration of the Event.
Trimming the begin boundary of a Playlist Event to the
right, gives that Event a later start time and shortens the
Event. Trimming the end boundary of a Playlist Event to
the left, gives that Event an earlier end time in the
timeline and shortens the Event. Trimming (extending)
the end boundary of a Playlist Event to the right, gives
that Event a later end time and lengthens the Event.
To Use the Trim Event Tool:

Move Event Tool

The Move Event tool is used for moving Regions forward
146

The Trim Event tool is used to trim or extend an Event’s
begin or end boundary. It is represented by a ->] or []).
2. When the Trim Event tool has become active, click
and drag over the Playlist Event’s begin or end
boundary – to move the boundary earlier in the
timeline, drag to the left, and to move it later, drag
to the right.

Playlist Events are targeted for editing processes.
To Select a Playlist Event in the Waveform View Area:

•

Click the desired Playlist Event – you will know it is
highlighted because it will appear in a different
color than other, unselected Playlist Events.
(Colors will vary depending on your color
preference settings).

High-Precision Editing Mode

When using the Move Event Tool, Trim Event Tool, Scroll
Regions Mode, or Preserve Timing Mode, you can use a
modifier key to temporarily toggle into High-Precision
Editing Mode. The modifier key is the Control (Ctrl) key
on your keyboard. Whenever this key is held down while
using one of the aforementioned tools or modes, the
tool/mode will make edits in one millisecond
increments. For example, if you use the Trim Event tool
while holding down the Ctrl key, the Event boundary will
be trimmed by one millisecond at a time.

If the Audio CD mode checkbox is checked, HighPrecision Editing mode will make edits at increments of
one CD Frame at a time.

Selecting Playlist Events

Once a few Regions have been added to a Playlist (and
are now referred to as Playlist Events), they will usually
need to be edited in some way. This editing may include
trimming, nudging, entering metadata, etc. Regardless
of the type of edit to be performed, it is important to
know how to make selections, as this is how particular

Creating Transitions between Playlist Events

There are four distinct types of transitions available
between adjacent Playlist Events. These include butt
edits, crossfades, gaps, and pauses.

Butting Playlist Events Together

Crossfading Playlist Events Together

Butt edits are the default type of transition created as
multiple Events are added to a Playlist. In a butt edit, two
Events are positioned back-to-back, with no space
between them.
In the case that an Event is no longer butted against its
preceding Event, it is easy to put it back into this
position.
148

After Butting

Another type of transition between Playlist Events is a
crossfade. A crossfade is a transition in which two Events
overlap in time – that is, before the earlier Event ends,
the later Event has already started. In the area where the
two Events overlap, the earlier Event fades out, as the
later Event fades in. In a typical crossfade, the overall
volume level remains more or less constant, though it
will depend on the audio content. Peak offers many

Peak 5 User’s Guide

crossfading options, making it possible to achieve
practically any effect desired.

To Change the Duration of a crossfade in Waveform View
with the Trim Event Tool:

•

In a crossfade, two Playlist Events overlap each other in time

Using the Trim Event tool, click and trimming the
“Out Event’s” end boundary to the left (earlier in
time) shortens both the Event and the crossfade,
while trimming (extending) the end boundary
lengthens the Event and crossfade. Trimming
(extending) the “In Event’s” begin boundary to the
left (earlier in time) lengthens both the Event and
the crossfade, while trimming it to the right
shortens both the Event and the crossfade.

To Crossfade Playlist events in Waveform View:

6

1. Locate two adjacent Events you wish to crossfade
together.
2. Click on the earlier (or “Out”) Event, and drag it to
the right (later in time), so an overlap in time is
created between the two Events. (Or, click on the
later (or “In”) Event, and drag it to the left, or
earlier in time, until an overlap is created.
To Change the Duration of a crossfade in Waveform View
with the Move Event Tool:

•

Using the Move Event tool, click and drag one of
the component Events that make up a crossfade to
the left or right – moving the “Out Event” to the
left (earlier in time) shortens the crossfade, and
moving it to the right (later in time) lengthens the
crossfade. Moving the “In Event” to the left (earlier
in time) lengthens the crossfade, and moving it to
the right (later in time) shortens the crossfade.

Extending the selected In Region to the left (picture on left) lengthens the
crossfade, and trimming it to the right shortens the crossfade (picture on right)

To Change the Crossfade Type in Waveform View:

1. Select the crossfade you wish to edit (remember
that to “select” a crossfade, you must select the “In”
component of the crossfade).
2. In the upper left portion of the Playlist interface,
click the Crossfade Type button, and choose the
desired type of crossfade from the pop-up menu –
both components of the selected crossfade receive
a new fade envelope shape.

4. Drag the breakpoint to the desired location on the
envelope’s curve.
Setting a custom gap or pause between Playlist Events

Gaps and pauses are very similar in most regards – they
create a short delay between two Playlist Events – but
pauses can be used in a unique way, that gaps cannot. A
gap can only be used to create a silent space between
two Playlist Events.

5. Continue creating and dragging breakpoints until
you have created the fade envelope that you
desire. If you wish to delete a breakpoint, click on
it with the cursor and press the Delete key on your
150

This picture shows a short gap between two Playlist Events

Peak 5 User’s Guide

A pause can be used for the same purpose, and can also
be used to create a space that contains audio.

This picture shows a silent pause

When a pause is created between two Playlist Events, the
pause’s duration is a unique entity, it is not added to the
preceding Event, nor is it added to the following Event.
When burned to CD, a CD player’s counter does not add
the pause to the preceding or following track, but
instead, when the preceding track ends, the counter
counts backwards (on players that support this) for the
duration of the pause, and when it ends, the track
counter is incremented, and the next track begins
playing.
To Create a Gap between Playlist Events in Waveform
View:

For example, you might be mastering a live concert
recording, which contains long sections of audience
applause between songs. By creating a pause containing
audio (the audio in this example being applause)
between two songs, you can create an audio CD which
when played through from beginning to end will play
both the songs, and the applause between them. If the
listener navigates using the next track or previous track
controls on the CD player, the player will jump directly to
the beginning of the song, and will skip the applause that
occurs before it.

1. Locate the two Events you wish to create a custom
gap between.
2. Using the Move Event tool, drag the later Event to
the right (later in time), until the desired gap
length is created between the two Events.
3. To Preview the gap, click in the timeline, a few
seconds ahead of the gap – audio playback starts
from this point. (For other previewing options, see
the upcoming section on Previewing transitions
between Playlist Events).
To Create a silent Pause between Playlist Events in
Waveform View:

1. Locate the two Events you wish to create a custom
pause between.

This picture shows a pause containing audio from the previous Event
– in this example, the audio in the pause is audience applause from
the end of the preceding song.

When a gap is created between two Playlist Events, the
gap’s duration is added as silence to the end of the
preceding Event, and the silence is considered to be part
of the earlier Event. When burned to CD, a CD player’s
counter treats a gap as part of the preceding track.

2. Using the Move Event tool, drag the later Event to
the right (later in time), until the desired pause
length is created between the two Events.
3. Drag the later Event’s Pause indicator to the left
(earlier in time), until it is aligned with the earlier
Event’s end boundary.
4. To Preview the pause, click in the timeline, a few
seconds ahead of the gap – audio playback starts
from this point. (For other previewing options, see

Chapter 6: Playlists & CD Burning

Playlist Events earlier in this chapter).
To Create a pause containing audio between Playlist
Events in Waveform View:

1. Locate the two Events you wish to create a custom
pause between.
2. Drag the later Event’s Pause indicator to the left
(earlier in time), until it is at an earlier point in the
timeline than the end boundary of the preceding
Event.

By setting a negative Track Start Offset marker (into the preceding
Event’s content), we’ve set a “virtual” track start time earlier than it
would normally appear (by default, it would normally appear in the
same position as the Event’s begin boundary).

To Set a Track Start Offset later than an Event’s begin
boundary in Waveform View:

•

Click and drag the Track Start Offset to the desired
position.

Setting Track Start Offsets

Track Start Offsets are used to create “virtual” start times
– that is, they trigger where the counter display advances
to the next track and dictate where a CD track index is
placed. When an audio CD featuring Track Start Offsets
is played back in a CD player, these offsets determine the
point where the CD player’s counter advances to the
next track. They also determine the point within a
track’s content that audio playback starts, when the next
track or previous track controls are used.
Track Start Offsets are particularly useful when you need
to precisely position a track’s start time within a
crossfade between two Playlist Events. By default, an
Event’s/Track’s start time is located at the same position
as the Event’s own begin boundary. In a crossfade
between two Events, the use of a custom Track Start
Offset allows the actual start time to occur at any point
within the crossfade.

By setting a positive Track Start Offset (into the In Event’s content), we’ve
set a “virtual” track start time later than it would normally appear (by
default, it would normally appear in the same position as the In Event’s
begin boundary).

This picture shows another variation – a pause containing audio from
the previous Event, and a positive Track Start Offset at the center of
the crossfade.

To Set a Track Start Offset earlier than an Event’s begin
boundary in Waveform View:

•

Start Offset, or later than the Event’s end
boundary.

are described in the order they appear by default. Due
to Peak’s highly customizable nature, you are free to click
and drag the columns and fields into any order desired,
but be aware that if you have changed them from their

in the same order, though there is no difference in
functionality.

List View Columns, Controls, and Data Fields

This section describes each of the controls found in the
List View Area.

Show/Hide List View disclosure triangle

This small black triangle appears to the left of the “List

control that is typically used to show or hide additional
information or interface controls. In this case, when the
List View disclosure triangle is pointing to the right

of the Playlist’s interface. When the disclosure triangle is
pointing downward (open position) it is showing, or
“disclosing”, the List View portion of the interface.

LE

Peak LE does not feature this disclosure triangle,
as it uses only one Playlist view (List View).

Program Duration Time Display

Directly opposite from the Show/Hide List View
disclosure triangle, you will find the Program Duration
display. This display shows the duration of all the
contents in the Playlist, from beginning to end, and takes
into account all crossfades and gap times. By default, this
display appears in the interface frame which separates
the Waveform View from the List View. When the
Waveform View is hidden, the Program Duration appears
above the List View, below the Nudge Controls, and
when the List View is hidden, it appears in the window
frame, just below the Waveform View Area.

Track Number Column

The Track Number column displays the track number of
each Playlist Event. The number displayed in this

Chapter 6: Playlists & CD Burning

153

column will become the CD track number if the Playlist
is burned as an audio CD, and also represents the Playlist
Event position when the Playlist is bounced to a new
audio document containing Region markers. This
number is not editable – the only way to change a Track
Number is by changing the order of Events in a Playlist.

Track End Time Column

Track Name Column

Track Duration Column

The Track Name column displays the names of Events
used in a Playlist. By default a Track Name appears
exactly as the Region’s original name appears in its
source audio document, though it can be edited in the
Playlist. A single click on an item under the Track Name
column makes the text editable, and a new name may be
entered. Changing the name in the Playlist does not
affect the name of the original source Region in its audio
document.

This column shows the overall duration between a
Playlist Event’s Begin and End Boundaries. A single click
on an item under the Track Duration column makes the
value editable, and a new Duration may be entered.

This column shows the End Time for a Playlist Event.
This value corresponds with the position of the Event
End Boundary. A single click on an item under the Track
End Time column makes the value editable, and a new
End Time may be entered.

Gap/Pause Duration Column

The Track Start Offset column displays a Track Start
Offset Time value, if one is used – and corresponds to
the position of the Track Start Offset in the Waveform
View display area. By default, a track’s start time is set to
an Event’s Begin Boundary, and displays a value of zero
seconds (or equivalent in the chosen Time Units). A
Track Start Offset allows the actual track start time to
have an independent value, so that a track’s actual start
time can be set before or after an Event’s Begin
Boundary. To edit a Track Start Offset in List View, click
in an Event’s TS Offset data field under the TS Offset
column – the Edit Track Start Offset dialog will appear.

The Gap/Pause Duration Column displays a Gap/Pause
Duration value, if one is used – and corresponds to the
position of the Gap/Pause indicator in the Waveform
View display area. By default, the Gap/Pause between
tracks is zero seconds (or equivalent in other Time Units)
– this is displayed in the Gap/Pause column, and the
Gap/Pause indicator (in Waveform View) is locked to an
Event’s Begin Boundary. A typical use for a Gap is having
two seconds or so of silence between two CD tracks. A
typical use for a Pause containing audio is in a live
recording, where the audience applause between songs
is placed in the pause – in this scenario, if a listener
advances to this CD track, they can skip over the
applause and go right to the song, but if they listen to the
CD from beginning to end, they would hear the applause
between songs. Clicking in a Playlist Event’s Gap/Pause
field makes it editable, and a new value may be entered.

Track Start Time Column

Crossfade In Shape Field/Column

This column shows the Start Time for a Playlist Event.
This value corresponds with the position of the Playlist
Event Begin Boundary, as well as the default position of
an Event’s Track Start Offset, and Pause/Gap indicator. A
single click on an item under the Track Start Time
column makes the value editable, and a new Start Time
may be entered.

Fields appearing under this column display a thumbnail
representation of the Fade In envelope shape being used
for the Playlist Event. Double-clicking on the thumbnail
graphic will open the Playlist Event Crossfade In editor
dialog, allowing you to modify the shape of the fade
envelope. A number of preset fade envelope shapes are

XFade Linear Blend – When this fade envelope is
used, the rate at which the amplitude decreases is
linear, and amplitude decreases smoothly at all
stages of the fade out. This is the default fade type,
and is also the most commonly used fade type.

Fields displayed under this column show the amount of
non-destructive gain change – from the original level in
the source audio document. Changes applied here affect
only the Playlist Event, not the source Region in the
source audio document. A Playlist event’s gain setting
can be used to control the balance of the event in a
Playlist. You may need to raise the volume or lower the
volume of some Playlist events to maintain a proper
balance of volume levels. You can make adjustments to
the gain of individual Playlist Events as you playback the
Playlist.

Be careful not to set a Playlist event’s gain too high
as you may overload the signal and cause
clipping to occur. You may also introduce clicks
between Playlist events if the difference in gain
between the two playlist events is too large.
Crossfades can help smooth these transitions.

Emphasis Column

This column’s checkboxes indicate whether a Playlist
Event is flagged for emphasis. The emphasis flag is one
of several available CD data subcode control bits that
trigger various behaviors when the CD is played.
Depending on the CD player, this flag may cause an
internal high pass filter to be engaged, boosting the high
frequency content of the track. Emphasis is not
commonly used.

Copy Protection Column

Vertical Scroll Arrows

This column’s checkboxes indicate whether a Playlist
Event is flagged for serial (SCMS) copy protection. The
copy protection flag is one of several CD data subcode
control bits that trigger various behaviors when the CD is
played. When this flag is turned on for a track, it could
prevent digital copies from being made.

The vertical scroll arrows appear just below the vertical
scrollbar, and serve the same purpose – but they scroll
vertically, by one Playlist Event at a time.

Vbox Effects Pop-Up Menu

Peak’s Playlist allows VST and Audio Units effects plug-ins
to be used (via the Vbox routing interface) on Playlist
Events. Each Playlist Event can have a unique effects
“snapshot” assigned to it. These effects are applied as
the Playlist is auditioned, and also when bounced as a
new document, or when burned to audio CD.

CD-TEXT Column

Horizontal Scrollbar

The horizontal scrollbar is one of the bottom-most
graphical elements of the List View Area, and appears
only when there is more graphical content than can be
displayed on-screen at the current Playlist window width.

Horizontal Scroll Arrows

The horizontal scroll arrows appear to the right of the
horizontal scrollbar, and like the scrollbar, are used for
scrolling through columns horizontally, when the Playlist
window’s width cannot fit all the columns.

This column’s checkboxes indicate whether the CDTEXT data for a track is valid for burning to CD.
Changing the Order of Columns
Some of the List View’s fields may be changed
simultaneously, for multiple Playlist Events. The
fields that allow this are Track Start Offset,
Gap/Pause, I-XF, O-XF, I-XF-T, and O-XF-T. To
change values in these fields for multiple items,
you must select the desired Playlist Events, and
then double-click in the field you wish to change.
A dialog appears, allowing a value to be entered –
this value is then applied to the respective field for
all selected Playlist Events.

When working in List View, you can organize the
columns in any order you like. This can be especially
useful if you are working on a narrow monitor, and not
using all the columns. In this scenario, you might
reorganize the columns so that all the data you are using
can be seen at all times, without needing to scroll the
window.
To customize the order of columns in List View:

•

Click a column header and drag to the left or right.

Vertical Scrollbar

The vertical scrollbar appears along the right side of the
Playlist window, when List View is showing. This
scrollbar is used for moving up and down through the list
of Playlist Events, when there are more than can be
displayed at the current window height.

Selecting Playlist Events

Once a number of Regions have been added to a Playlist
(and are now referred to as Playlist Events), chances are,
they will need to be edited in some way. This editing

Peak 5 User’s Guide

Regardless of the type of edit to be performed, it is
important to know how to make selections, as this is how
particular Playlist Events are targeted for editing
processes.

Changing the Order of Playlist Events

To change the order of multiple adjacent Playlist Events:

Changing the order of Playlist Events is something that is
only possible using List View.

1. Select the Events you wish to move to a new
position.

To change the order of a single Playlist Event:

1. Select the Event you wish to move to a new
position.
2. Drag the selected Event up or down, to desired
position in the List of Playlist Events, highlighting
the name of the Event you wish the selected Event
to appear before.

2. Drag the selected Events up or down, to desired
position in the List of Playlist Events, highlighting
the name of the Event you wish the selected Events
to appear before.
For example, to move the first, second, and third Events
into the third, fourth, and fifth positions in the List of
Events, you would select, click, and drag the first,
second, and third Events , moving them over the fifth
event (fifth event will become highlighted), and release
the mouse button.

To change the order of Playlist Events, click and drag Event to a new
position...

For example, to move the second Event into the third
position in the List of Events, you would select, click, and
drag the second Event, moving it over the third event
(third event will become highlighted), and release the
mouse button. In this scenario, Events 2 and 3 change
place, and no other Events are affected.

Here, we are dragging Event 2 over Event 3, so Event 2 will become
the third Event, and Event 3 will be pushed up in the list, becoming
the second Event

To change the order of multiple Playlist Events, click and drag Events
to a new position...

In this scenario, Events 1, 2, and 3 now become Events
3, 4, and 5, and Events 4 and 5 are pushed up the list to
become the first and second Events.

Here, we’ve moved Events 1, 2, and 3 into the third, fourth, and fifth
positions, by dragging them over Event 5. Events 4 & 5 now become
the first and second Events.

Crossfading Playlist Events Together

Creating Transitions between Playlist Events

There are four distinct types of transitions available
between adjacent Playlist Events. These include butt
edits, crossfades, gaps, and pauses.

The List View does not offer a graphical
representation of the various transitions. You may
wish to review the section about Creating
Transitions in the Waveform View area, to get a
better understanding of the different types of
transitions. The Creating Transitions in the
Waveform View section contains pictures of of
each type of transition, which may make it easier
to understand.

Butting Playlist Events Together

Butt edits are the default type of transition created as
multiple Events are added to a Playlist. In a butt edit, two
Events are positioned back-to-back, with no between
them.
In the case that an Event is no longer butted against its
preceding Event, it is easy to put it back into this
position.
To Butt an Event to the preceding Event in List View:

1. Click the desired Playlist Event’s Gap/Pause data
field – the field becomes editable.
2. Enter a value of zero, and press the Return key –

Another type of transition between Playlist Events is a
crossfade. A crossfade is a transition in which two Events
overlap in time – that is, before the earlier Event ends,
the later Event has already started. In the area where the
two Events overlap, the earlier Event fades out, as the
later Event fades in. In a typical crossfade, the overall
volume level remains more or less constant, though it
will depend on the audio material. Peak offers many
crossfading options, making it possible to achieve
practically any effect desired.
To Crossfade Playlist Events in List View:

1. Locate two adjacent events you wish to crossfade
together in List View.
2. In the earlier Event’s (the “Out Event”) row, click in
the O-XF-T Column (or “Out Crossfade Time”) –
the field becomes editable.
3. Enter an earlier value than the Start Time of the
following Event (the value that appears in the
following Event’s Start Time Column) and press
the Return key on your keybaord.
Or:
1. Locate two adjacent events you wish to crossfade
together in List View.
2. In the later Event’s (the “In Event”) row, click in the
I-XF-T Column (or “In Crossfade Time”) – the field
becomes editable.
3. Enter a later value than the End Time of the
preceding Event (the value that appears in the
preceding Event’s End Time Column) and press
the Return key on your keyboard.

it will automatically appear in the Envelope popup menu it the Fade In/Out Envelope editor.
Please note that you must apply the custom fade
in/out for it to later appear in the pop-up menu.

Setting Custom Gaps or Pauses between Playlist Events

Gaps and pauses are very similar in most regards – they
create a short delay between two Playlist Events – but
pauses can be used in a unique way, that gaps cannot. A
gap can only be used to create a silent space between
two Playlist Events. A pause can be used for the same
purpose, and can also be used to create a space that
contains audio.
For example, you might be mastering a live concert
recording, which contains long sections of audience
applause between songs. By creating a pause containing
audio (the audio in this example being applause) between
two songs, you can create an audio CD which when played
through from beginning to end will play both the songs,
and the applause between them. If the listener navigates
using the next track or previous track controls on the CD
player, the player will jump directly to the beginning of the
song, and will skip the applause that occurs before it.
When a gap is created between two Playlist Events, the
gap’s duration is added as silence to the end of the
preceding Event, and the silence is considered to be part
of the earlier Event. When burned to CD, a CD player’s
counter treats a gap as part of the preceding track.
When a pause is created between two Playlist Events, the
pause’s duration is a unique entity, it is not added to the
preceding Event, nor is it added to the following Event.
When burned to CD, a CD player’s counter does not add
the pause to the preceding or following track, but
instead, when the preceding track ends, the counter
counts backwards (on players that support this) for the
duration of the pause, and when it ends, the track
counter is incremented, and the next track begins
playing.
To Create a Gap between Playlist Events in List View:

1. Locate the Events you wish to create a gap
between.
2. In the later Event’s row in List View, double-click

Chapter 6: Playlists & CD Burning

163

under the Gap/Pause column – the Playlist Event
Gap Time column appears.
3. Enter the desired Gap length, and click OK – the
later event is moved later in the timeline by
whatever amount was entered in the Playlist Event
Gap Time dialog.
To Create a silent Pause between Playlist Events in List
View:

1. Locate the Events you wish to create a pause
between.
2. In the later Event’s row in List View, single-click the
Event’s Gap/Pause field – after a short delay, it will
become editable.
3. Enter the desired pause length, and press the
Return key on your keyboard – the later event is
moved later in the timeline by the amount you
entered in the Gap/Pause field, and the Pause
indicator is automatically aligned with the end
boundary of the preceding Event.
To Create a pause containing audio between Playlist
Events in List View:

1. Locate the Events you wish to create a pause
between.
2. In the later Event’s row in List View, click the
Event’s Gap/Pause field – it will become editable.
3. Enter the desired pause length, and press the
Return key on your keyboard.
4. For the same Event, click the Start Time field – it
will become editable.
5. Adjust this value by subtracting the duration of the
pause from the previous Start Time.

00:10:30:000, and the pause amount entered in Step 3
was 5 seconds, the new Start Time should be
00:10:25:000. This has the same effect as creating a silent
pause, and then dragging the later Event to a position 5
seconds earlier in the timeline using Waveform View.
Note that the Butt to Previous Event End command may
also be used in place of steps 4 and 5 above.

Setting Track Start Offsets

Track Start Offsets are used to create “virtual” start times
– that is, they trigger where the counter display advances
to the next track and dictate where a CD track index is
placed. When an audio CD burned from a Playlist
featuring Track Start Offsets is played back in a CD player,
these offsets determine the point where the CD player’s
counter would advance to the next track. They also
determine the point within a track’s content that audio
playback starts, when the next track or previous track
controls are used.
Track Start Offsets are particularly useful when you need
to precisely position a track’s start time within a
crossfade between two Playlist Events. By default, an
Event’s/Track’s start time is located at the same position
as the Event’s own begin boundary. In a crossfade
between two Events, the use of a custom Track Start
Offset allows the actual start time to occur at any point
within, before, or after the crossfade.
To Set a Track Start Offset in List View:

1. Click once over the desired Playlist Event’s Track
Start Offset (TS Offset) data field – after a short
delay, the field contents become editable.
2. Enter a new Track Start Offset value, and press the
Return key on your keyboard – the Event’s
corresponding waveform display has its Track Start
Offset indicator moved to reflect the new value.

For example, if the Event originally had a Start Time of

timeline than the preceding Event’s Track Start
Offset, or later than the Event’s own end
boundary.

it. These types of metadata include Track Title,
Performer, Songwriter, Composer, Arranger, and ISRC
code.
To Add CD-TEXT to a Track:

Adding Metadata to Discs & Tracks

1. Check the CDTXT checkbox for the desired Playlist
Event – the CD-TEXT for Track dialog opens.

A variety of metadata may be added to entire discs, and
to individual CD tracks. Metadata is added in two
formats – CD-TEXT, and embedded subcode data. CDTEXT appears in the display of compatible CD players,
and subcode data triggers certain behaviors (such as
emphasis or copy protection) on compatible players.

6

Subcode data is not displayed – it is read by compatible
CD players and used for a variety of purposes, such as
tracking copyrights and royalties (with ISRC codes), or
looking up a CD’s info via an online service such as
Gracenote’s CDDB™, which is used by some softwarebased CD players like Apple’s iTunes™.

Comparing the embedded ISRC codes on an audio CD with those
stored in an online database is one of several ways for a softwarebased music player to automatically get and display CD track names.

While Peak’s Playlist supports writing the entire
spectrum of metadata on both a per-disc and per-track
basis, be aware that most CD players do not support
reading/displaying this data. In addition, compatible CD
players will vary in the types of metadata they read or
display.

2. Enter the desired types of metadata, and click OK
– when burned to audio CD, the metadata will be
included.
3. When you burn the Playlist to CD, check the Burn
CD-TEXT from Playlist checkbox in the Burn Audio
CD dialog.
About ISRC Codes

Track-Specific Metadata

Various types of track-specific metadata may be added to
a Playlist project, and will be added to CDs burned from

ISRC codes can be burned to CD as CD-TEXT, and/or as
embedded subcode channel data.

Chapter 6: Playlists & CD Burning

165

To add an ISRC Code to a track as CD-TEXT:

ISRC codes may be entered either in the CD-TEXT
dialog, or directly into a Playlist Event’s ISRC data.
Be aware that having entered an ISRC code, and
having the CDTXT checkbox checked will only
burn ISRC codes as CD-TEXT data, which is
displayed on compatible CD players as the CD is
played back. To burn ISRC codes as audio CD
subcode data, which is used for commercial CD
copyrights, etc. you must have entered an ISRC
code, and checked the Write ISRC Codes checkbox,
which appears in the Burn Audio CD dialog.
Burning ISRC codes as subcode data operates
independently of the CDTXT checkbox – whether it
is checked or not determines only whether an ISRC
code (and other fields in the CD-TEXT dialog) is
burned as CD-TEXT, which is displayed on a
compatible CD player, but is not related to
copyrights and royalty tracking.

1. In the desired Playlist Event’s row, click the CDTXT
checkbox – the CD-TEXT for Track dialog opens.
2. In the ISRC field, enter your ISRC code, and click
OK – be sure the CDTEXT checkbox is checked.
3. When you burn the Playlist to CD, check the Burn
CD-TEXT from Playlist checkbox in the Burn Audio
CD dialog.

Burning CD-TEXT requires Mac OS X v. 10.4 or
later, and a compatible CD burner!

To add an ISRC Code to a track as subcode channel data:

1. In the desired Playlist Event’s row, enter your ISRC
code in the ISRC field.
CD-TEXT compatible CD players vary in what
embedded information they actually display. The
most common information displayed is the CD
Title, Performer, and Track Title. Check the
documentation that was included with your CDTEXT compatible CD player for more information
on what types of CD-TEXT data it is capable of
displaying.

2. When you burn the Playlist to CD, check the Write
ISRC Codes checkbox in the Burn Audio CD dialog
– the ISRC codes in the Playlist are burned as
subcode data.

ISRC codes may be burned as both CD-TEXT and
embedded subcode data simultaneously by
following both sets of steps outlined above. To do
this, you must enter an ISRC code, check the
Playlist’s CDTXT checkbox, and also check the
Write ISRC Codes checkbox in the Burn Audio CD
dialog.

166

Editing Subcode Data

Peak’s Playlist is capable of editing Emphasis and Copy
Protection subcode data bits. While these subcodes are
rarely used, there may be times when you wish to enable
these subcodes. More information about using these
subcodes is available earlier in this chapter.

Peak 5 User’s Guide

To add an Emphasis (Emp/PE) Flag to a Track:

•

Check the Emphasis (Emp) checkbox for the
desired Playlist Event – when burned to audio CD,
this track will trigger compatible CD players to turn
on a high pass filter to boost high frequencies.
Markers become Indexes when the Markers are Indexes checkbox is
checked in the Burn Audio CD dialog

CD Burner Compatibility
To add a Copy Protection flag to a Track:

•

Check the Copy Protection (CP) checkbox for the
desired Playlist Event – when burned to audio CD,
this track will feature digital copy protection.

The digital copy protection the Copy Protection
subcode bit is designed to protect against is
copying to DAT tape. It does not protect against
digital copies made using computer-based CDROM drives, and stand-alone CD recorders.

Indexes

In addition to track indexes, which designate the start or
end of a CD track, you may also burn standard indexes to
audio CDs using Peak. Indexes are created by placing
Markers in the desired location within a source audio
document that is referred to by a Playlist. Indexes are
not visible when working in the Playlist, but are burned
to CD. Indexes are commonly used on classical music
CDs, where a track may be relatively long (i.e., 20
minutes or more), and indexes appear at various
intervals or points of interest, within a single CD track.
With CD indexes in place, a listener can navigate to the
index location using the indexing controls on a
compatible CD player. Most CD players do not support
navigation using indexes.

In addition to requiring Mac OS X v.10.4 or later to burn
CD-TEXT, your Macintosh must also have a CD burner
capable of burning this type of data. You may want to
check with your CD burner’s manufacturer to find out
about what types of data is capable of burning, or you
can use a handy UNIX command in the Terminal utility.
The Terminal application is located in the Utilities folder,
within the Applications folder.
To check your CD burner’s compatibility with the Terminal:

1. Open the Terminal application (from /Macintosh
HD/Applications/Utilities/)
2. At the $ prompt, type: “drutil info” and press
Return – you will see something that looks like
this:

The UNIX command “drutil info” reveals the capabilities of the
CD/DVD burner in a Macintosh. In this picture, we can see that the
drive in question supports writing CD-Text, as well as Index Points, and
ISRC codes.

Applying Effects Plug-Ins to Playlist Events

Unique effects “snapshots” may be assigned to each
Playlist Event. These effects are applied to each Event
during Playlist preview, as well as when
bouncing/exporting the Playlist, and burning audio CDs.
Effects snapshots contain information about the
arrangement of effects within the Vbox matrix, as well as
the settings of each individual plug-in.
There are a number of controls used to configure Vbox’s
effects settings for each Playlist Event. These controls
are:
Off – The Off control turns off/bypasses any effects

that are assigned to a Playlist Event.

On – The On control activates effects that are
assigned to a Playlist Event. If Vbox is not active,
the On control activates Vbox on the first available
effects insert (i.e., if no effects are active, Vbox will
be actived on effect Insert 1. If an effect is already
active on Insert 1, Vbox will be actived on Insert 2,
and so on.)

The Set control takes a snapshot of the
current Vbox state for the selected Playlist Event.
This snapshot includes information about which
effect(s) are active and which box(es) they occupy,
as well as each effect’s current settings.
Set –

168

The Make Active control displays the
settings that are assigned to the selected Playlist
Event. This control is especially useful when you
wish to apply the same effect(s) snapshot to
multiple Playlist Events. You can select the Playlist
Event that has the desired snapshot assigned to it,
and choose the Make Active menu item, which
displays the settings for that Playlist Event. Then
you can assign these settings to another Playlist
Event which does not have a snapshot already
assigned to it, by selecting the target Playlist Event,
and choosing the Set menu item. The first Playlist
Event’s snapshot is applied to the targeted Playlist
Event, and they both share an identical effect(s)
snapshot.

Make Active –

The Clear control clears any snapshot
assigned to the selected Palylist Event.
Clear –

This section will teach you how to configure these
effects. More general information about using Vbox and
effects plug-ins is available in Chapter 8: Plug-Ins.

Peak 5 User’s Guide

To enable Vbox state automation for a Playlist Event:

•

From the Vbox pop-up menu, choose On – If Vbox
inactive, this command opens it. If Vbox is already
open, this command has no additional effect.

To disable Vbox state automation for a Playlist Event:

•

From the Vbox pop-up menu, choose Off – Vbox is
disabled for this Playlist Event, though the Vbox
interface will remain active and visible.

To take a “snapshot” of the current plug-in settings:

1. From the Vbox pop-up menu, select On – If Vbox
inactive, this command opens it. If Vbox is already
open, this command has no additional effect.
2. Configure Vbox with the desired effects plug-ins.
3. From the Vbox pop-up menu, select Set – a
“snapshot” of the current state is saved.

4. Select the next Playlist Event (and repeat for all
subsequent Events on which you wish to use
“snapshot” automation).
5. From the Vbox pop-up menu, select On.

To Make a Playlist Event’s “snapshot” active:

1. Select the Playlist Event which contains the
“snapshot” you wish to make active.
2. From the Vbox pop-up menu, select Make Active.
3. Select a different Playlist Event, on which you wish
to assign the “snapshot” made active in the
previous step.
4. From the Vbox pop-up menu, select Set – the
“snapshot” used on the Playlist Event chosen in
Step 1 is assigned to the Event selected in Step 3.

6

To clear a Playlist Event’s “snapshot”:

1. Select the Playlist Event which contains the
“snapshot” you wish to clear.
2. From the Vbox pop-up menu, select Clear – the
selected Playlist Event no longer contains a saved
“snapshot”.
Clicks or pops may occur if your effect snapshots
include any settings that instantiate and deinstantiate plug-ins. The reason for this is that
there is always a very short delay between actually
choosing a plug-in from a menu, and that plug-in
being instantiated. When a Playlist is going from
one Event to another very rapidly (especially on
slower computers) clicks and pops may occur.
Therefore, it is recommended that if you want to
use different plug-in configurations for each
Playlist Event, configure Vbox with all the plug-ins
you want to use for all Playlist Events, and then
create snapshots for each Playlist Event with the
plug-ins that you don’t want to use on that Playlist
Event muted or bypassed. (For more information
on using Vbox, please refer to Chapter 8: Plug-Ins)

6. From the Vbox pop-up menu, select Set – a
“snapshot” of the current state is saved for this
Playlist Event.
Chapter 6: Playlists & CD Burning

169

If you plan on creating crossfades and using
effects snapshots in a Playlist, it is recommended
that you apply effects plug-ins to Regions in their
source documents, before adding them to the
Playlist. The Playlist uses state automation, and
“snaps” from one effects setting to the next
instantly. If the effects used from one Playlist Event
to another differ greatly, the result can be an
abrupt transition from Event to the next. By
applying the effects in the original source
documents, the transition from one Playlist Event
to another will occur smoothly, and effects
differences between Events will be smoothed out by
the crossfade between them.

CD Burning Options

The Burn Audio CD dialog contains a number of CD
burning options, which are described below.

Burner Pop-up Menu

Output Options
Peak’s Playlist offers a wide variety of output options,
including burning audio CDs, exporting an entire Playlist
as a single audio document, as a text file, as a DDP (Disc
Description Protocol) file set, or as a Jam Image file.

Burning Audio CDs

Burning audio CDs is one of the most common ways to
output digital audio projects edited in Peak. CDs may be
burned directly from an audio document, or from a
Playlist document. When burning from a Playlist made in
Audio CD mode (i.e., with the Audio CD checkbox
checked), the resulting CD will conform to the Red Book
standard, and will be playable in any CD player (except
for player that are not compatible with CD-R media).
Burning a CD not made in Audio CD mode may play on
a standard CD player, but this will depend largely on the
CD player’s capabilities. For maximum compatibility, it is
recommended to burn in Audio CD mode. For more
information, please review the section on Audio CD
mode which appears earlier in this chapter.

170

This menu allows you to choose which CD burner you
wish to use (when more than one burner is connected to
your computer).

Burn Speed Pop-up Menu

This menu allows you to choose the desired burn speed.
Generally, lower speeds will produce the most reliable
CDs. It is a good idea to check the burn speed rating of
the blank CD media you are using to find out what its
maximum recommended burn speed is.

Use POW-r Dither Checkbox

The state of this checkbox determines whether POW-r
dither should be applied to a Playlist during the burning
process. If you are working with 24-bit content, it is
recommended that you check this box, so as to reduce
the bit depth to 16-bit, while maintaining the highest
possible quality through dithering. If this box is not
checked, 24-bit files are simply truncated.

Peak 5 User’s Guide

Verify After Burn Checkbox

Regions are Tracks Checkbox

The state of this checkbox determines whether a burned
CD is compared to the audio data contained in the
Playlist and source audio documents, to verify its
accuracy. To verify a CD, be sure this box is checked.

The state of this checkbox determines whether each
Event should become a separate CD track. If this box is
not checked, one long track will be burned.

Burn in Simulation Mode Checkbox

The state of this checkbox determines whether Peak
burns in simulation mode. In simulation mode, a CD is
not actually burned – instead, Peak goes through all the
motions of burning, and will uncover any problems with
a Playlist before committing to a burned CD. This option
is helpful as “burning” in simulation mode can help save
blank media. To use simulation mode, be sure this box is
checked, and be sure to uncheck it when you are ready
to burn a CD.

This checkbox also affects burning CDs from
audio documents. When burning from an audio
document, any Regions it contains will translate
into separate CD tracks, if this box is checked.
Otherwise, the audio document will be burned as
one long track.

6
Markers are Indexes

The state of this checkbox determines whether Markers
placed in a Region’s source audio document are burned
to CD as indexes within tracks.

Use Buffer Underrun Protection Checkbox

The state of this checkbox determines whether Buffer
Underrun Protection is used while burning a CD. Buffer
underrun errors result from a hard drive not being able
to transmit audio data to a CD burner fast enough while
burning a CD. It is recommended that this box be
checked during the burning process, though most drives
support this automatically.

Burn CD-TEXT from Playlist Checkbox

The state of this checkbox determines whether CD-TEXT
entered in the Playlist is burned to CD. To burn CDTEXT to disc, be sure this box is checked.

Write ISRC Codes Checkbox

The state of this checkbox determines whether ISRC
codes entered in the Playlist are burned to CD as

Bounce button – a Save dialog appears.

With the optional DDP extension installed and active, Peak
is capable of exporting a Playlist in DDP (Disc Description
Protocol) 2.0 format, which is commonly used when
delivering a finalized mastering project for CD
manufacturing. DDP files ensures that audio files,
crossfades, edits, and all other data used in a Playlist remains
exactly in the state it was in when exported from Peak. This
highly secure format ensures that the audio data being
burned to CD in the manufacturing process is identical to
the mastering engineer’s intentions when creating the
Playlist in Peak. Exporting as a DDP File Set results in a
folder being created with the following four files:

4. Choose the desired save location, click the Save
DDP Fileset button, and name the folder to which
the DDP Fileset will be saved – the Playlist is
exported as a DDP file set.

DDPID contains the DDP level identifier,
Master ID and UPC/EAN number. It also locates
the DDPMS map stream for physically addressed
direct access input media. The DDP level identifier
specifies the level of DDP implemented and the
interpretation of the other DDP streams.
DDPID –

DSP

Introduction
Peak allows you to transform your audio with a variety of
powerful Digital Signal Processing (DSP) tools. You can
apply these tools at any time by first making a selection
in an audio document and then choosing the desired
menu command from the DSP menu.

4. Set the parameters for the DSP function as desired
and click OK. Peak processes the selection with
the DSP function or plug-in.

Note that if no selection is made, Peak will apply
processing to the entire audio document.

Processing Audio with Peak’s DSP
Tools
The following general procedure describes how to
process a selection in an audio document, or the entire
document, with a particular DSP function. The specific
capabilities and parameters of the DSP function will vary.
To process audio with a DSP function:

1. Select the portion of the audio that you wish to
process with the DSP function. If no selection is
made, the entire document will be processed.
2. Select the type of process you wish to use from the
DSP menu.
3. A dialog appears allowing you to set the
parameters for the DSP function.

Peak’s Audio Processing Tools
Peak’s DSP capabilities provide composers and
professional sound designers with many interesting and
useful audio effects and processing tools. Peak’s many
DSP functions include Add, Amplitude Fit, Auto Define
Tracks, Bit Usage, Change Duration, Change Gain,
Change Pitch, Convert Sample Rate, Convolve, Crossfade
Loop, Envelope From Audio, Fade In, Fade Out, Find

The following sections explain how to use each of these
functions.
Add

The Add command adds any selection of audio copied to
the clipboard into the audio document at the selection
point. To use the Add command, you must first copy a
selection of audio. The copied material can then be
mixed into the target audio material. The Add command
can also be customized using an envelope. If you wish to
Add material with a variable level, click the envelope
button in the Add dialog. The Add function differs from
the Mix function slightly, in that the Add function never
alters the amplitude level of the target audio material you
are adding to – you can only specify the level of the
material you are adding.

button, create the desired envelope, click the
Change button, and then click the Add button. Be
careful not to add too high an amount, which can
potentially clip the signal.
5. Click OK. Peak adds the two signals together.
6. To hear the results, press the Spacebar.

LE

Add is not available in Peak LE.

Amplitude Fit

Amplitude Fit provides granular normalization of an audio
selection on a grain-by-grain basis. Grains are small groups
of samples, often around 30ms. As each grain is read in, it is
normalized according to the Amplitude Fit Envelope – each
normalized grain crossfaded with the previous grain and
written out as the result. Amplitude Fit can be used to
maximize the level of an audio selection, or to make quiet
passages as loud as louder passages.

The Add dialog

To use the Add command:

1. Select the audio that you wish to Add to another
audio document and choose Copy from the Edit
menu (-C) or Toolbar.
2. Select the audio that you wish to add the copied
material into.

audio selection in the envelope editor. Points above and
below the 0% line will normalize the selected audio using
the grain-by-grain normalization technique.

LE

Amplitude Fit is not available in Peak LE.

Auto Define Tracks

The Auto Define Tracks dialog

The Auto Define Tracks tool allows you to automatically split
audio recordings into separate Regions, each of which will
become an individual CD track when an audio CD is burned.
This tool is useful for quickly editing LP and cassette
recordings, in preparation for burning them to CD, or
exporting them for use with a portable music player, such as
Apple’s iPod.

Since some songs may contain very quiet parts that could
mistakenly be interpreted as gaps between tracks, a few
parameters are available to help Peak correctly
distinguish between songs and the gaps between them.

This DSP tool works by automatically placing Region markers into
an audio document based on audio level, minimum period of
silence between songs, and minimum song duration. Peak analyzes
the audio levels throughout a document, and places Region
markers around each song. The louder parts are considered to be
songs, and the quieter parts are the gaps between them.

Minimum Silence Between Tracks

This field is used to enter the minimum gap time
between songs in the audio document you are working
with. If a recording you are working with contains two
second gaps between each song, start with the default

Before using the Auto Define Tracks tool on an LP recording – note the area of silence near the middle of the recording has not yet been edited out...

value of “2.00” in this field. If the gaps between songs
vary in length, enter the value of the shortest gap in the
entire recording.

If you need to measure the gap time between
songs, activate the Cursor Info overlay by selecting
Show Cursor Info (-Shift-T) from the Options
menu, and then select the gap between songs in the
audio waveform – the Cursor Info overlay will tell
you the length of the selected area. You may also
need to set your preferred Time Units to
Min:Sec:ms – this can be done in the Options
Menu>Time Units.

Minimum Track Duration

Peak needs to have some information about the length of
each song, in order to accurately divide a long recording
into individual songs. The Minimum Track Duration
parameter tells Peak how long the shortest song in a
recording is, and helps ensure that Region markers are
placed in the correct location in the audio waveform –
that is, a begin Region marker just before a song starts,
and an end Region marker just after a song ends – even
if the audio level falls below the threshold value set with
the Silence is Audio Below slider (see next section). If a
recording you are working with contains songs that are
all approximately 4-5 minutes long, a good value to enter
in this field would be 240 seconds (4 minutes).
Silence is Audio Below slider

Number of Songs field

This numerical field is tied to the Silence is Audio Below
slider, and displays the number of songs that Peak
automatically detects in a recording, based on the
settings used for Minimum Silence Between Songs,
Minimum Track Duration, and Silence is Audio Below.
Depending on the settings you choose, Peak will detect
a different number of songs, and this field will display
different numbers. When the Silence is Audio Below
slider is moved, the number of songs detected will
update, and typing in a new value in the Number of
Songs field will update the Silence is Audio Below slider.
Typically, the automatic number of songs detected is very
accurate, provided you have entered accurate settings
for the other parameters that define tracks. There may be
times however, where Peak detects more or fewer songs
than the recording actually contains. You may choose to
define the number of tracks using the Silence is Audio
Below slider, or by typing in a known number of songs in
the recording, and then fine tuning with the Silence is
Audio Below slider. Be aware that the values you enter in
the Number of Songs field, and the values you set with
the Silence is Audio Below slider may override each
other.
To Auto Define Tracks:

This slider controls the threshold level between audio
material you wish to define as a Region and the gaps
between it. As this slider is moved, you will notice Region
markers appearing in the audio waveform in the
background, and you will also notice the value in the
Number of Songs field changing. (More information on
the Number of Songs field is in the next section). For
example, if you are working with a recording from a
cassette, the gaps will typically contain hiss or other
180

noise that is not completely silent, but has a significantly
lower amplitude level than the program material that you
are trying to isolate into tracks. By adjusting the Silence
is Audio Below slider, you can make the judgment as to
what should be silence, even if it does contain some low
level audio such as tape hiss, or other background noise.

1. Open a recording from a cassette or LP.
2. Select All (-A).
3. From the DSP menu, choose Auto Define Tracks.
4. In the Minimum Silence Between Songs field, enter
the shortest amount of time (gap time) between
any two songs in the entire recording.

Tips for using Auto Define Tracks

Before Auto Defining Tracks
–

When recording cassettes and LPs, you will be working
with fairly long audio documents, and there are a few
things you can do to get the most accurate results with
the Auto Define Tracks tool.
•

Zoom out all the way, so that you can see the entire
audio document from beginning to end. This way,
when setting parameters in the Auto Define Tracks
dialog, Region markers being placed into the audio
waveform will be visible throughout the document.

•

Delete excess silence – if you have recorded excess
silence at the beginning or end of the audio
document, or recorded a long pause when
“flipping” a cassette or LP, it’s a good idea to edit
this out before attempting to use the Auto Define
Tracks tool.

•

You may want to apply noise reduction for clicks,
crackles, pops, broadband noise, and hum before
auto-defining tracks. These types of noise are
reflected in the audio waveform and may interfere
with accurate placement of markers. Some of
Peak’s built-in tools can help reduce/remove
certain kinds of unwanted noise, but for the best

The number of songs in the recording – you
should be able to see how many individual
songs there are by counting the number of
high amplitude areas.

–

The shortest song – select the shortest song
from beginning to end, and then turn on
Cursor Info, which will show the length of the
selected part of the waveform. You may need
to zoom in to make a more accurate selection.

–

The shortest gap time between songs – select
the gap between songs and measure using
the Cursor Info overlay.

After Auto Defining Tracks

There may be times when an anomaly in the audio
waveform, or a less than ideal setting causes a
track/Region marker to be placed in the wrong location.
In some cases, when most of the tracks have been
identified correctly, but one or two have not, it may be
easiest to simply adjust the markers that are in the wrong
position.

Chapter 7: DSP

181

7

Region markers may be moved by clicking and dragging
the triangular base to the left or right. Also, by engaging
Peak’s Vertical Lock mode, you may move the end of one
song/Region and the beginning of the next at the same
time.
This technique is especially useful when working with
live recordings or DJ mixes, where it’s important to
preserve the overall duration and timing – but a track
index needs to be adjusted into the correct position.

To use the Bit Usage meter:

1. Select the desired range of audio you wish to
examine.
2. Choose Bit Usage from the DSP menu – The bit
usage meter will appear, and plot a graph showing
the status of bit usage in the selected area of audio.

LE

Nudging Markers

If all the Region markers placed into an audio document
are incorrectly placed, but are off by a small amount, you
may wish to use the Nudge feature to adjust them all
simultaneously. To nudge a group of markers, select the
portion of the audio waveform that contains the markers
you wish to nudge, and then choose Nudge from the
Action menu. Now that you know a bit about Peak’s Auto
Define Tracks tool, give it a try! This feature can save a
great deal of time, and the more you use it, and get a feel
for how the various parameters need to be set, the faster
it will work.

Bit Usage

The Bit Usage meter allows you to monitor bit saturation,
degradation, and the “true” bit depth of a file.

Bit Usage is not available in Peak LE.

Change Duration

You can specify the change in duration by a value in
seconds, a percentage of the original, or, for
rhythmically-oriented material, beats per minute. In
addition, when working with rhythmically-oriented
material, a special Transient mode may be used for
optimal results.
A change in duration by a reasonable amount, about 85%
to 115%, can be very convincing. Exaggerated time
stretching, 200% or more, can result in some very
interesting granular textures. Try experimenting with the
Change Duration function on drums, rhythm loops,
speech, sampled instruments or sound effects to achieve
a wide variety of useful effects.

recommended starting point.

LE

Peak LE features a more basic Change Duration
algorithm. It features the same controls with the
exception of the Tempo Envelope, and is limited in
quality compared to the algorithm used in Peak
Pro and Peak Pro XT.

Change Gain

The Change Gain function changes the gain (i.e.,
amplitude) of a selection. You can specify the amount of
gain change either in decibels (dB) or as a percentage. If
you wish to double the volume of a sound, you must apply
approximately 6 dB of gain change, or add 200%. Enable
the Clipguard checkbox in the Change Gain dialog to

protect against the possibility of clipping. Clipguard will
search through the audio document or selection for the
maximum peak in amplitude, and then limit the Change
Gain slider’s range based on the maximum peak it finds in
the audio document or selection.

The Change Pitch dialog uses a pitch slider that allows
you to choose a new pitch by musical interval, and “fine
tune” the pitch change by smaller increments called
“cents.” (Cents are divisions of a musical octave-one
octave is equivalent to 1200 cents – thus, 100 cents is a
semi-tone, 50 cents a quarter-tone, etc.)
You can also choose to alter the length, or duration, of
the selection just as you would by slowing down or
speeding up analog tape, or you can choose to preserve
the duration of the selection (something not possible
with analog tape!).

conversion is applied to an entire document. It
cannot be applied to just a selection within a
document. Refer to Chapters 3 and 4 for an
explanation of commonly used sample rates.

The Convert Sample Rate dialog

Sample rate conversion quality may be set in the
DSP Preferences section of the Preferences dialog.
A setting of 1 is lowest quality (and uses the least
amount of CPU power and takes the least amount
of processing time) and 10 is the highest quality
(using the most CPU power and taking the longest
to process).

A Sample Rate Conversion setting of 8 is the
recommended starting point.

The default setting for sample rate conversion is 8,
and this should work well in most cases. In a
practical sense, use the highest setting possible for
your particular computer system’s CPU.

Peak LE features a more basic Change Pitch
algorithm. It features the same controls, but is
limited in quality compared to the algorithm used
in Peak Pro and Peak Pro XT.

To change the sample rate of a document:

The Macintosh’s built-in audio hardware is
typically limited to sample rates from 11 kHz to 64

model of Macintosh. Higher sample rates are
possible with Core Audio depending on the
particular audio hardware device and its Core
Audio drivers.

Because the clipboard contents that provide the spectrum
for this process must be held in RAM, small clipboard
impulses should be used, unless a large amount of RAM is
available. This process can use a lot of RAM!

To use Convolve:

1. Select the audio with the characteristics you wish to apply
and choose Copy (-C) from the Edit menu or Toolbar.

LE

Peak LE contains a basic sample rate conversion
algorithm

3. Choose Convolve from the DSP menu. Peak
applies the spectral character of the copied
material to the selection.

Convolve

The Convolve command is a unique and powerful sound
design tool that allows you to apply the sonic (i.e.,
spectral) characteristics of one sound onto another.
Convolution works by multiplying the frequency spectrum
of the impulse contained in the clipboard and that of the
target audio document, reinforcing the frequencies that
are in common between the two. The results are always
interesting and often quite unlike anything you’ve heard
before. This is especially true when the character of the
two sounds are very different, and when the clipboard
impulse is harmonically rich (imagine, for example,
convolving a rainfall sample with piano tinkling!). To use
the Convolve DSP command, you must first copy a
selection of audio. The copied material will provide the
spectral “character” that you will apply to the target audio
material. Convolution can be very useful not only for
creating new and unusual sound, but also for giving an
audio selection a sense of space. Try copying a small
amount of room noise to the clipboard and then Convolve
it with a selection of audio – the convolved audio will
sound like it is being played in that room environment.
Users of the Convolve feature will also enjoy the additional
parameters of the ImpulseVerb DSP tool, when set up to
use the Clipboard contents as a convolution source (See
the section on ImpulseVerb later in this chapter for more
information).

Crossfade Loop

Peak allows you to crossfade the start and end points of
a loop. Crossfading a loop can be very useful for
smoothing the transition between the end of the loop
and its beginning as it repeats. Peak allows you to
control the envelope of the crossfade, the duration, and
other parameters in the Crossfade Loop dialog.

The Crossfade Loop dialog

Peak 5 User’s Guide

The four checkboxes at the top of the Crossfade Loop
dialog allow you to customize how the end of the loop is
faded into the beginning of the loop. These boxes
indicate where in the loop the crossfade is applied. For
most loops, you should be able to leave the default

If you consider the crossfades “A”, “B”, “C”, and “D” from
left to right, then:
“A” =

Crossfade between A and C

“B” =

Crossfade between B and D

“C” =

Crossfade between C and A

“D” =

Crossfade between D and B
A

B

C

Another application that may require using loop crossfade
position(s) other than the default position “C”, are when
creating audio loops intended to be used in a proprietary
video game audio engine. Depending on the requirements
of a particular video game’s audio engine, users may need to
adjust the position of the crossfades used in their loops to
achieve the desired effect. Depending on the application
requiring crossfades, users may need “loop with release”
(plays the tail of the audio document – the section of audio
that lies outside the loop markers – after the loop stops
playing/sampler’s key is released) or “loop hold” (doesn’t
play the audio after the loop when the key is released).
Because of these different modes, users may need to turn
some crossfades on or off.
To crossfade a loop:

1. Create a loop using one of the techniques
explained earlier in this chapter.

D

2. Choose Crossfade Loop from the DSP menu or
Toolbar.
3. In the Crossfade Loop dialog that appears, enter a
duration for the crossfade-in milliseconds and click
OK.

Crossfade positioning options – different uses for loops may call for
different loop crossfade settings – With crossfade position “C”
checked a crossfade is applied as indicated by the red “X”

The way these crossfade variations are configured
depends on where the loop is destined to be used –
for most purposes the default crossfade position
(Position “C”) works well – if however, you plan on
transferring these loops to a sample playback
instrument such as a SMDI sampler, then you may
want to experiment with different crossfade
positions/combinations. Some hardware based
samplers offer advanced playback controls, allowing
loops to be played forward, backward, and in various
other ways. By changing where in the loop crossfades
are applied, you can customize your audio content for
a particular sampler and for the desired effect.

Loop from the Edit menu, select Use Loop in
Playback from the Options menu (-L) or click

The Envelope from Audio tool allows you to create an
envelope from a selected portion of audio. For example,
imagine a piece of music that has a specific type of fade
out, and you would like to be able to apply that fade out
“envelope” to other pieces of audio. By selecting the
entire fade out, and then using the Envelope from Audio
command, Peak is able to “reverse engineer” the fade out
characteristics, and save them as an envelope that can
later be recalled in any of Peak’s envelope based tools,
such as Fade In/Out, Gain Envelope, etc. Once an
envelope is saved, it is available for use in any of Peak’s
DSP tools that are able to access the Peak Envelopes
folder, stored in your Home directory’s Preferences
folder. Other DSP tools that can access these envelopes
include Fade In/Out, Blending, Panner, Gain Envelope,
Amplitude Fit, and Plug-In Envelope.
Envelopes of varying precision may be created with this
tool. For a more precise envelope, where more points
define the shape, enter a smaller value in milliseconds in
the “ms” field (or use the slider). For a less precise (or
“smoother”) envelope, where fewer points define the
shape of the envelope – use a larger value.

adjust with the scroll bars at the bottom of the
window to achieve a natural transition at the loop
point by carefully adjusting the slope alignment.
The arrows of the slider will move the loop
markers sample by sample and clicking in the body
of the slider will move the loop markers to the next

Mix

The Mix command allows you to mix material that you
have copied to the clipboard with a target selection. This
function can be used as a kind of “sound-on-sound”
capability for mixing audio tracks together, or for
blending sound elements. The Mix command is similar
to the Add command, but it does not have the potential
to clip because the target and clipboard contents are
attenuated before mixing. To use the Mix command, you
must first copy a selection of audio. The copied material
can then be mixed into the target audio material. The
Mix command also allows an envelope to be applied to
the copied material. This can be useful when the content
being mixed needs to have variable levels in it. The Mix
function differs slightly from the Add function, in that the
percentage slider affects both the material being mixed,
as well as the original target material. For example, a
50/50 mix will lower the amplitude level of the target
material.

Modulate

This Modulate command functions as a “ring modulator”
which multiplies two audio signals together (e.g., the
material copied to the clipboard and the currently
selected audio). The resulting audio includes the sum
and difference tones of the frequency components of the
modulated audio and the modulating audio. These are
generally very complex timbres that often have a
“metallic” (i.e., inharmonic) character to them.

Try using generated tones, like sine, swept sine,
square, or saw-tooth waves with the Modulate
command.

Normalize

This command allows you to optimize the volume of a
selection or an entire audio document so that it is at its
maximum possible amplitude without clipping. The
normalize function is very useful for boosting the volume
of material that was recorded at too low a level, or if used
on multiple audio documents, for making sure that the
amplitude of each of the documents is uniform.

Peak 5 User’s Guide

Note that because normalization uniformly
changes the amplitude of a selection (i.e., the
proportions between loud and soft stay the same),
it does not have the same effect as
compression/limiting (which makes the soft parts
louder and does not allow the loud part to exceed
a specified amplitude).

To normalize a selection:

1. Select the audio that you wish to normalize. If you
wish to normalize the entire audio document,
choose Select All from the Edit menu (-A).

signal, the Soft Clip feature will automatically activate and the
resulting RMS level will be lower than the one specified by the
user. The processed file will be as loud as possible while
guaranteeing that the signal will be limited to the ceiling
specified by the user.
The RMS Normalize dialog offers two parameters – RMS
Level and Digital Ceiling. RMS Level allows you to enter
the desired RMS Level (or average level), and the Digital
Ceiling allows you to limit the maximum audio level,
which is also the level at which Soft Clipping will activate,
if the RMS Level exceeds it.

Panner

The Panner allows you to adjust the panning, or left-toright movement, of a stereo document by drawing an
envelope in the Panner dialog. Left is at the top of the
graph, and right is at the bottom.
The Panner also offers an option to keep volume
constant as audio pans from side to side. When the Keep
Volume Constant checkbox is enabled, Peak uses
Logarithmic calculation to determine volume levels
while panning between the left and right channels –
resulting in overall volume levels being preserved. When
this option is not enabled, Peak uses linear calculations
and does not preserve volume levels. When disabled, it
is common to have dips in the overall audio level when
panning from one channel to the other.

or other intervals. Use the direction pop-up menu
to control whether the pitch is shifted upward or
downward.
5. In the Analysis Settings field, select the number of
bands and FFT (Fast Fourier Transform) size to
determine the quality of the output. The Phase
Vocoder works by analyzing the frequency content of
the audio selection and placing the found
frequencies into tracks. These tracks are then used
to control an oscillator-based resynthesis that uses
the pitch and duration modifications you enter. In
general, using a smaller FFT size brings less smearing
of the audio output than higher FFT sizes. Using a
larger number of bands setting used increases the
accuracy while tracking of harmonic content of the
source sound. In general, setting the FFT size larger
than the number of bands will give undesirable
results. Due to the nature of the Phase Vocoder’s
algorithm, optimum results are achieved when it is
used with solo instruments and steady state sounds
(such as a voice or solo flute line) rather than
complex tones (such as an orchestra playing).

Detection Setting

Repair Clicks

The Repair Clicks command allows you to find and repair
pops or clicks in an audio document. The Repair Clicks dialog
automates the process of finding and removing clicks (usually
indicated by a sharp “spike” in a waveform), much like a
search and replace dialog in a word processor.
The Repair Clicks operation works by looking for any
significant discontinuity from sample to sample. For
example, a sample value of -100 followed by a sample
value of 10,000 is likely to be a click. Once the area of the
click is identified, a smoothing technique is used to
maintain the original shape of the area being repaired.
If you are working with mostly digitally induced clicks,
the Repair Clicks dialog will become an indispensable
tool. Extremely damaged signals such as those of a
scratching and popping vinyl record will require more
careful repair in addition to using the Repair Clicks
dialog, such as Change Gain, Delete, and the Pencil Tool.
Clicks such as those of a scratching and popping vinyl
record lose their detectability once they are sampled
using Analog to Digital converters.
198

The Detection Setting value determines how the clicks
are located. Higher values locate only the most severe
clicks, while lower values will detect less severe clicks.
Note that lower values such as 10% also have a greater
chance of misjudging audio for a click. In general, a
setting of 40-80% works well.
Repair Size

The Repair Size setting affects how many samples around
the click are used in determining the new shape of the
repair. Repair size can vary from 5 to 100 samples, with
a repair size of 50 samples working well in most
circumstances. Peak will then interpolate what the
correct waveform should be, and repair the click.
Buttons along the bottom of the Repair Clicks dialog allow you

Remove DC Offset

This function allows you to remove any DC Offset in your
audio file. Peak scans the audio for DC offset and then
removes it. Peak will scan the left and right channels of
a stereo file independently. DC Offset is usually caused

The result is that the waveform is not centered on the
base line – it is offset either higher or lower than the
center line.

Strip Silence

Peak includes a Strip Silence tool, which allows
areas of silence, or very low amplitude, to be
automatically silenced, minimized, or completely
removed from an audio document. This tool is
useful for removing silence from recordings that
predominantly contain silence (or very low level
audio content), interspersed with some desired
audio content. By adjusting the various Strip
Silence parameters, you can control what content
is preserved, and what is silenced completely or
deleted from an audio document.
The Strip Silence tool is composed of two sections,
the Noise Gate and the Stripper.

The Reverse Boomerang dialog

simply reduced in level depends largely on the setting
used for the Reduction Ratio slider. The Reduction Ratio
slider provides a proportional amount of reduction for
any audio with a signal level that falls below the
threshold level.

Noise Gate

The Noise Gate functions similarly to any other noise
gate, and its controls include:
Threshold Slider

The Threshold slider determines the level at which all
audio with a higher signal level is preserved, and at a
lower level is either silenced/reduced in level.
By
default, the Threshold slider is set to a value of -20dB,
and has a range of 0dB to -60dB.
Setting the Threshold slider is fairly straightforward – for
example, if working with a dialogue recording in which the
voice has a nice strong level, but the ambient room tone is
still audible (around -30dB), you would set the Threshold
slider right around -30dB. This control allows you designate
a level above which audio will be preserved – and a level
below which audio will be silenced, or removed.

A high setting on the Reduction Ratio slider will reduce
low amplitude sections of the audio waveform (what is
considered “low amplitude” depends on the level set
with the Threshold slider) to complete silence. A lower
setting on the Reduction Ratio slider will reduce low
amplitude sections of the audio waveform slightly (again,
what is considered “low amplitude” depends largely on
what setting is made to the Threshold slider). By default,
the Reduction Ratio slider is set to a value of 2.00, and
has a range of 1.00 to 5.00.
Using the same example of working with a dialogue
recording, which has an ambient room tone around –
30dB, which we would like to minimize. If the Threshold
slider is set to about -30dB, that targets the audio below
that level only to be reduced – by how much depends on
how the Reduction Ratio slider is set. To silence these
sub -30dB sections completely, a high setting, such as 4
or 5 might be used for the Reduction Ratio slider.
However, to maintain some amount of room tone, use a
milder setting between 1 and 3.
Attack Slider

A good technique for determining the Threshold
slider setting is by first selecting a portion of audio
containing just the background noise/room tone
(what should be silence, and should be removed),
and using Peak’s Find Peak DSP tool to determine
the exact level. This level can then be used as a
Threshold slider setting in the Strip Silence tool.

The Attack slider determines how quickly level reduction
happens, once audio falls below the threshold level
(which is set with the Threshold slider). By default, the
Attack value is set to 20 milliseconds, and has a range of
10 milliseconds to 500 milliseconds.
Release Slider

Reduction Ratio Slider

This slider provides a proportional amount of reduction,
based on the setting of the Threshold Slider. Whether
audio below the threshold is completely silenced or

The Release slider determines how quickly level
reduction turns off, once audio exceeds the threshold
level (which is set with the Threshold slider). By default,
the Release value is set to 100 milliseconds, and has a
range of 50 milliseconds to 1000 milliseconds.

Chapter 7: DSP

A good rule of thumb for making settings to the Attack and
Release sliders is to take into account the type of audio
material that you’re with. For example, if working with
dialogue, it takes a relatively long time for a spoken word to
go from zero amplitude to full amplitude, (long attack time)
so it’s best to use a higher attack setting. This will cause the
reduction to be applied more gradually. Likewise, with this
type of material, it’s best to use a longer release time setting
as well, as spoken words tend to gradually diminish in
amplitude, rather than end very abruptly.

below the level set with the Noise Floor slider) are
required before silent areas can be eliminated.

LE

Strip Silence is not available in Peak LE!

Swap Channels

On the other hand, consider a drum recording. Drums have
a much faster attack time – that is, it takes much less time to
hit a drum and have it go from zero amplitude to full
amplitude. Once it’s been hit, it also takes a very short time
to diminish to silence. This type of audio material would
require much shorter attack and release times.

The Swap Channels command reverses the left and right
channels in a stereo selection.
To swap channels for a stereo selection:

1. Select the audio that you wish to swap. If you wish
to select the entire document, choose Select All
from the Edit menu (-A).

Stripper

The Stripper is the section of the Strip Silence tool that
will delete sections of audio that fall below a certain level
and stay below that level for a certain length of time. The
Stripper’s behavior depends on the settings made with
the following parameters:

2. Choose Swap Channels from the DSP menu. Peak
swaps the left channel for the right channel and the
right channel for the left channel. To hear the
results, start playback.

Noise Floor

This slider functions much like the Threshold slider in the
Noise Gate section of the Strip Silence tool. Setting this
slider more to the left has the effect of using a lower
threshold setting in the Noise Gate section – that is, only
audio material with the lowest signal level would be deleted.
On the other hand, when this slider is set to a more
“aggressive” setting, audio with a higher amplitude level
would also be deleted. Audio is only deleted when it stays
below a certain level for a certain length of time. The Noise
Floor Slider has a range of 0.0000 – 1.0000%.
Required Silence Before Strip Slider

This parameter controls how many milliseconds of
consecutive silence (silence being any audio with a level

LE

Swap Channels is not available in Peak LE.

Threshold

The Threshold command allows you to split up an audio
document into its component parts by analyzing the
amplitude levels in the audio document and setting a
cutoff or threshold amplitude. For instance, you might
use the Threshold command on an audio document that
contains successive notes from a musical instrument to
split them up, or on a drum loop to break it up into its
component parts. You can save the segments with
Markers, or as Regions.

Peak 5 User’s Guide

To use the Threshold command:

1. Select the audio you wish to process and choose
Threshold from the DSP menu. After Peak analyzes
the amplitudes in the selection, the Threshold
dialog will appear, allowing you to select a threshold
amplitude for both attack and release values.

4. Adjust the Attack value. This parameter sets the
amount of time that audio must stay above the given
threshold to qualify as a new marker or region.
5. When you have finished, click OK.
6. After the audio document has been “thresholded”
to your satisfaction, you can use the Export
Regions command in the File menu to export the
separated regions into new windows or files.
7. To select and play regions in order from left to
right, press the Page Up key on your computer
keyboard. To select and play regions in order from
right to left, press the Page Down key.

The Threshold Regions dialog

Use the Threshold command to create several
looping points. To convert a marker to a Loop
Start or Loop End point, double-click on the
marker and change it to “Loop Start” or “Loop
End” in the Edit Marker dialog. Also, try
rearranging the regions generated by the
Threshold function in the Playlist or by using Cut
and Paste to create new interesting compositional
and rhythmic ideas!

2. Drag the threshold indicator left or right to set the
threshold amplitude. As you drag the indicator, new
markers will appear in the audio document forming
markers or regions, depending on your settings. The
Offset sliders allow you to “nudge” the onsets of
markers or regions by plus or minus 0 to 512 samples.
3. Select Create Regions to create regions instead of
markers. The separate Release Threshold, attack
and sludge settings affect the region end points,
allowing you to eliminate silence from the region
end points.

Introduction
Peak supports Audio Units, and “carbonized” or “Mach-O” VST
format effects plug-ins and virtual instruments. Audio Units is a
plug-in standard, or format, created by Apple Computer, Inc.
VST (“Virtual Studio Technology”) is a standard audio plug-in
technology developed by Steinberg Media Technologies, AG.
Both Audio Units & VST plug-ins formats offer an exciting array
of real-time effects and instruments from companies like BIAS,
Cycling 74, Korg, Maxim Digital Audio, Native Instruments,
Steinberg, Waves, and many others. Audio Units & VST plug-ins
operate in real-time, and are “native”, or “host-based”. This type
of plug-in is powered by your computer’s CPU, and does not
require any additional processing hardware. They work in realtime, meaning that any parameter changes are heard
instantaneously, and no processing time is required until the
desired settings are found. This avoids having to experiment
with settings, process, and then undo if the settings are not
correct.

Plug-Ins Included with Peak 5
Peak comes with a wide variety of plug-ins – some made
by BIAS and others made by third party manufacturers.
The list below shows which plug-ins are included in each
edition of Peak.
Documentation for BIAS plug-ins is available in separate
user’s guides, and is automatically installed into the
following directory:

Installing Plug-Ins

BIAS Plug-Ins

While Peak includes a wide variety of plug-ins,
there are hundreds of other Audio Units or VST
plug-ins that are available separately, and that are
compatible with Peak.

The BIAS plug-ins included with Peak are technically VST
plug-ins, but they are grouped separately from other VST
plug-ins.
BIAS VST plug-ins are automatically installed into:

A list of compatible plug-ins is available on the
BIAS website’s FAQ section, at:

/MacintoshHD/Library/Audio/Plug-Ins/VST/

http://www.bias-inc.com/support/faq/

VST Plug-Ins

Many third-party plug-in packages will include a
custom installer program that automatically installs
plug-ins in the correct directory, so that Peak and
other Audio Units/VST hosts can access them. Be
sure to consult the documentation that came with
your plug-ins for the manufacturer’s installation
instructions.
There are two locations that Audio Units or VST
plug-ins may be installed so that Peak can access
them – for more information, please see the next
section.

Installing a plug-in into the “global” VST directory at the
root level allows any user account that is logged in to
access these plug-ins.
/Macintosh HD/Library/Audio/Plug-Ins/VST/
Installing into the VST directory in a user’s Home
directory allows only that user to access these
plug-ins.
/MacintoshHD/Users//Library/
Audio/Plug-Ins/VST/

Audio Units Plug-Ins

Installing a plug-in into the “global” Components
directory at the root level allows any user account that is
logged in to access these plug-ins.
/MacintoshHD/Library/Audio/Plug-Ins/Components/
Installing into the Components directory in a particular
user’s Home directory allows only that user to access
these plug-ins.

While it does not matter whether you choose to
install into the global plug-ins directory, or the
plug-in directory in your Home directory, it is
easier to maintain a single plug-ins directory. If
you have plug-ins installed in both locations, and
wish to consolidate into a single directory, it’s easy
to move the plug-ins from one directory to the
other. The simplest way to do this is to open two
Finder windows next to each other, and drag the
plug-ins from one directory to the other. For more
information on organizing files in the Macintosh
Finder, please consult the documentation that was
included with your Macintosh.

Organizing Plug-ins with Folders

Vbox

When using many types of plug-ins from various
manufacturers, it is useful to be able to sort the plug-ins
in a particular way. For example, you may want to group
all of your EQ or reverb plug-ins together.

Peak includes BIAS Vbox for managing and mixing effects
plug-ins. Think of Vbox as a virtual effects box, in which
you can combine, repatch, and mix your effects plug-ins
in real-time. Using its unique effects matrix, Vbox lets
you combine multiple individual plug-ins. Vbox can
patch plug-ins in series, in parallel, or in series and
parallel, and you can hot-swap plug-ins. Vbox has
controls for each plug-in to mute, solo, and edit
parameters. Vbox also provides input and output gain
controls both globally and for each individual plug-in,
and a control for the global Wet/Dry mix. Use Vbox’s A/B
comparison feature to get just the right settings, and use
Vbox’s presets to store configurations and settings for
later use.

Audio Units plug-ins are automatically sorted into groups
based on the manufacturer.
BIAS plug-ins are automatically sorted into their own
plug-in category.
VST plug-ins may be organized in practically any way
desired – you might choose to organize by the type of
effect, or by manufacturer, etc. Peak allows you to
organize your VST plug-ins into folders inside the
“global” VST plug-ins folder (or the VST plug-ins folder
within your Home directory). Each folder you create
inside the VST plug-ins folder can store groups of plugins that will appear as submenus when assigning a VST
plug-in on a channel insert or within Vbox.

Using Effects Plug-Ins with Inserts
To open an Audio Units plug-in on an insert:

1. Select Insert 1 from the Plug-Ins menu.
2. Select Audio Units from the submenu.
3. Select the manufacturer from the next submenu.

Using Effects Plug-Ins
Peak can access Audio Units and VST format effects plug-ins in
two different ways – using “Inserts”, or through the Vbox
effects routing matrix. The method you choose will depend
on how many plug-ins are being used simultaneously, and the
functionality required for the task at hand.

4. Select the plug-in you wish to use from the next
submenu.

Inserts

Peak features 5 individual channel inserts and each insert
may contain a single plug-in. When using inserts, signal
flows through the effect in each insert in the order of the
insert number. For example, if an equalizer plug-in is
used on Insert 1, and a reverb plug-in is used on Insert 2,
the output of the equalizer plug-in will flow into the
input of the reverb plug-in. Inserts are typically more
convenient when using a small number of plug-ins.

plug-in assigned to a box, it is inactive.

An active box

An active box has several features including the
name of the assigned plug-in, input level control,
output level control, solo button, bypass button,
mute button, edit button, input meters, output
meters, and input source.

Vbox is ideal for working with multiple plug-ins

The Edit button brings up the plug-in editor for the plugin assigned to that box. The plug-in editor will appear in
a new window, and contains the plug-ins own user
interface, with all of its various controls available.

Editing Effect Plug-In Parameters
Virtual instrument plug-ins differ from effects
plug-ins in that they do not have the capability to
have audio routed into them – they do not have
audio inputs. The only input a virtual instrument
can receive is via MIDI. Due to this limitation, it
is normal for the input level sliders to have no
effect over the audio playback level for that
instrument. In addition, it is normal for there to
be no activity in the input level meters.

Clicking the Edit button on an active box opens its editor,
which is the plug-in’s own user interface. Here, you will
be able to access and adjust the parameters of the
specific plug-in. You can modify the parameters and save
your presets into a preset file using the Load and Save
buttons at the bottom of the plug-in’s editor window.
The arrow buttons allow you to move through any
existing factory presets for the plug-in, or click on the
name of the preset for the Presets pop-up menu.

Bypass Plug-In

Moving Plug-Ins
Bypass

The Bypass button prevents the plug-in from processing
the audio input to the box. The audio will flow through
the box directly to the outputs, or to other boxes in the

Vbox lets you move plug-ins from any active box to any
other box, active or inactive, in the Vbox matrix.
To move a plug-in from one box to another:

Virtual instrument plug-ins differ from effects plug-ins
in that they do not have the capability to have audio
routed into them – they do not have audio inputs.
The only input a virtual instrument can receive is via
MIDI. Due to this limitation, it is normal for Vbox’s
Master Input level slider to have no effect over the
audio playback level for an instrument in the
matrix. In addition, it is normal for there to be no
activity in Vbox’s Master Input level meters.

Loading and Restoring Vbox Presets

Vbox Preferences

You can control the size of the Vbox matrix by clicking
the Preferences button at the top of the Vbox matrix.
Enter the height and width of the matrix you wish to
build. Note the new matrix size will not take effect until
the next time you launch Vbox. The Vbox matrix can
grow as large as 99x99!

The Vbox Preferences dialog

Recording Through Effect Plug-Ins

You can save your Vbox matrix as a preset or restore a
Vbox matrix by clicking on the Presets pop-up menu at
the top of the Vbox matrix. Any presets you save into the
Vbox Presets folder will appear in the Presets pop-up
menu. The Vbox Presets folder resides in the following
directory on OS X:
/MacintoshHD/Users//Library/Preferences/

In addition to processing existing audio files, Peak also
allows recording through effect plug-ins. This can be a
very useful and timesaving step, especially when
recording in a known environment, or when the exact
same set of effects needs to be applied. While recording
through plug-ins, you are free to adjust plug-in
parameters – however, be aware that you will be making
permanent changes to the material that is recorded, and
will not be able to undo these adjustments.

A/B Comparisons

You can do A/B comparisons of different Vbox matrices.
Press the left arrow button to store the current Vbox matrix
into storage location A. Press the right arrow button to
store the current Vbox matrix into storage location B. Press
the A or B button to restore a saved matrix.

Peak 5 User’s Guide

While recording through plug-ins can be a
timesaver, be aware that if you are not happy with
the results, you cannot undo them. If you are not
sure about the settings to use, record a dry signal,
and apply effects later. This way, you can freely
experiment with effects settings and not have to
commit to them.

Regardless of whether you’re using effects plug-ins on
channel inserts or within the Vbox matrix, the process for
recording through them is the same.

To apply effects plug-ins dynamically:

1. Make a selection of the audio document you want
to process.
2. Choose Plug-Ins Envelope from the Peak’s
Preferences dialog.

To configure Peak to record through Plug-Ins:

1. From the Plug-Ins menu, open and configure the
plug-in(s) you wish to record through.
2. Select Record Settings from the Audio menu. The
Record Settings dialog will appear.
3. Check the Record Through Plug-Ins checkbox and
click OK.

3. A dialog appears allowing you to draw a breakpoint
envelope to control how much of the effect is
applied over time. Points at the top of the graph
represent 100% wet, while points at the bottom of
the graph represent 0% wet (dry).

4. Select Record from the Audio menu (-R) or
Transport. You are now ready to record audio
through the plug-in(s).
5. Be sure to disable the active plug-in(s) after you
have made the recording. If you do not
disable/bypass the plug-in(s), when you play back
the recording, you will hear a processed file being
played through the active plug-in in real time and it
will sound as if the recording has twice the desired
effect.

Plug-Ins Envelope dialog

4. When you are finished drawing an envelope, click
Change.
5. Configure the plug-ins you wish to apply.

Peak can only host (and record) through plug-ins
when using Core Audio.

6. Choose Bounce from the Plug-ins menu.

Plug-Ins Envelope
Plug-In Latency Compensation
Peak features an editable plug-ins envelope, which allows
applying a variable wet/dry mix over a selected portion of
an audio waveform. For example, if you have a dialogue
clip that you would like to apply reverb to, but would like
the amount of reverb to vary dynamically, you can create
a custom envelope that automatically varies the amount
of reverb applied to different portions of the clip.

Plug-ins may introduce a short delay, known as latency,
into the audio they are being used to process.
Depending on the type of processing the plug-in
performs, the amount of latency can vary – so it is
common for different plug-ins to produce varying
amounts of latency.

Chapter 8: Plug-Ins

217

Latency typically appears in audio documents after
bouncing, by a shift in samples later in time relative to
the document’s own timeline.
Peak features an automatic plug-in latency compensation
feature called Auto Adjust Bounce for Latency – which
automatically compensates for the latency introduced
into a processed signal.
Automatic latency compensation may be toggled on and
off from Peak’s Options menu.

1. Bounce effect(s).
2. Measure the silence inserted by the bounce by
selecting the silence and viewing the duration of
the selection in samples. ( You can use either the
time display counter in the Transport, or turn on
the Cursor Info overlay from the Options menu –
either way will show the length of the selected
piece of audio in the chosen Time Units. Time
Units should be set to Samples for this process).
3. Undo the bounce.

To Toggle Latency Compensation On/Off:

•

To determine delay compensation:

From Peak’s Options menu, select Auto Adjust
Bounce for Latency.

A check next to the Auto Adjust Bounce for Latency item
indicates that this feature is active. The absence of a
check next to this item means it is inactive.
Plug-in latency compensation may also be used manually.
To compensate for plug-in latency when bouncing effects
on a selection, hold down the Option key when choosing
Bounce, and enter the delay compensation you want in
samples in the Bounce Effects dialog.

4. Hold down the Option key while choosing Bounce
from the Plug-Ins menu.
5. Enter the delay compensation amount from step 2.
6. Click OK or press Return.

Using Effect Plug-Ins with the Batch
File Processor
Peak allows you to use your Audio Units and VST effect
plug-ins with the Batch File Processor (see Chapter 9:
Batch File Processor & Apple Events for a detailed
description of the Batch File Processor). This can be a
very powerful and timesaving processing option if you
need to apply the same plug-in(s) to many audio files.

The Bounce Effects dialog

To use plug-ins with the Batch File Processor:

1. Open an Audio Document.
You may only use manual delay compensation
when the Auto Adjust Bounce for Latency option is
disabled. When it is active, you will not be able to
access the Bounce Effects dialog by holding down
the Option key and choosing Bounce from the
Plug-Ins menu.
218

2. Open and configure the desired Audio Units or
VST plug-in(s) that you wish to use in the batch
process. (See the section on Using Effects Plug-Ins
earlier in this chapter for detailed directions on
opening plug-ins).

3. Choose Batch File Processor from the File menu.
4. Choose any other processes you want to use for
the Batch File Processor and Set the Batch File
Processor’s Output directory folder.
5. Add “Bounce” from the list of Available Processes
to the list of Selected Processes for Batch.
6. Turn the Batch File Processor On and click OK.
7. In the Finder, locate the files/folders you wish to
batch process – and drag and drop them over the
Peak application icon in the Dock.

Configuring Peak for Virtual Instrument
Playback

In order to play virtual instruments, you must enable a
keyboard input. Virtual instruments may be played by
clicking keys in Peak’s MIDI keyboard window, or by
enabling keyboard MIDI control (uses your computer’s
keyboard as a MIDI input), or by using an external MIDI
keyboard.
With Peak’s MIDI Keyboard Window:

•

From the Window menu, select MIDI – Peak’s
MIDI keyboard window appears.

8. Peak will batch process these files and save them to
the designated directory folder.

Peak LE does not support Batch File Processing.

Active virtual instruments now receive input when keys
in Peak’s MIDI keyboard window are clicked.
With your Computer keyboard:

Using Virtual Instrument Plug-Ins
Peak supports Audio Units and VST format virtual
instruments. Virtual instrument support in Peak offers a
quick and easy way to record performances, and greatly
expands the scope of Peak’s sound design possibilities.
Virtual instruments may be used in Peak in a variety of
ways. A single virtual instrument may be loaded on a
channel insert, or multiple virtual instruments may be
loaded into Vbox and be played simultaneously.
Instruments may be loaded for playback as well as for
recording directly to a Peak audio document.

•

From the Options menu, select Keyboard MIDI
Input.

Active virtual instruments now receive input when keys
on your computer’s keyboard are pressed.
With an External MIDI Controller:

Virtual instruments may also have effects plug-ins
chained in a series after them, so the effects plug-ins are
used to modify the instrument’s output.
Before playing virtual instrument plug-ins, an input
method must first be configured.

1. Connect a MIDI interface to your Macintosh and
follow its installation/setup instructions. After you
have configured your MIDI interface, launch Peak.
2. Open Peak’s Preference Panel>MIDI Preferences.

Once a MIDI input method has been configured, it’s very
easy to play a virtual instrument in Peak.
Active virtual instruments now receive input when keys
on your MIDI controller are pressed.

To Play an Instrument:

1. Load the desired instrument plug-in.
Depending on the MIDI interface you are using,
you may need to install a driver (provided by the
interface manufacturer). You may also need to
restart Peak and/or your computer before the
computer recognizes that a keyboard is connected
– your computer needs to recognize that an
interface is connected before Peak can use it for
MIDI input.

Now that an input method has been configured, you may
open and play any Audio Units or VST format virtual
instrument plug-ins that are installed in your system.
Just as when using effects plug-ins, virtual
instruments may be used on channel inserts or
within the Vbox matrix. The steps below describe
how to use virtual instruments in a variety of ways.

2. Click a note in Peak’s MIDI keyboard window,
using the keyboard on your computer, or using a
MIDI controller.

Recording Virtual Instruments
At some point, you will probably want to record your
virtual instrument performances. This is a very simple
process.
Peak can record the audio output of virtual instruments
directly into a Peak audio document. The configuration
for recording virtual instruments is similar to recording
through effects plug-ins.

Batch File Processor
and Apple Events

Introduction
Peak allows you to process any number of audio files at
once with any number of possible processes using the
Batch File Processor. Peak also supports Apple Events,
which allows you to manage whole libraries of audio files
quickly and easily with database applications such as
FileMaker Pro.

Batch File Processor
Peak’s Batch File Processor is one of the most powerful,
versatile, and useful features in Peak. Using the Batch
File Processor, you can integrate any series of Peak
processes (called a batch script), and apply these scripts
to any number of audio files.

The currently open audio document and selection
you make will be used for previewing processes
sequenced into your batch script.

To use Batch File Processing, go to the File menu and
select Batch Processing. The Batch File Processor dialog
appears.
Peak’s Batch File Processor is split into three areas: Input,
Process, and Save Changes. Sequence a series of steps
for Peak to execute in the Process section, then set your
output file settings in the Save Changes area. Once

9

Peak’s Batch File Processor

Peak’s Batch File Processor is configured, you may turn
on the Batch File Processor in the Input area.
Once the Batch File Processor is configured and turned
on, any files you drop onto the Peak application’s icon
(or an alias) will be batch processed according to your
settings. You can even drop folders or disks onto Peak’s
icon and all of the supported audio contents will be
batch processed. You can continue dropping files,
folders, or disks, onto the Peak icon for batch processing
while the Batch File Processor is turned on. All
subfolders within folders or disks you drag onto the Peak
application icon for Batch File Processing will be
recreated in the Batch File Processor’s output directory,
preserving all organization of your files. Audio
documents opened using the Open command from the
File menu will not be batch processed.

Chapter 9: Batch File Processor & Apple Events

225

You can also have the Batch File Processor run in
the background while you work in another
application.
Supported contents include all file formats that Peak can
read, including AIFF, Sound Designer II, WAVE,
QuickTime, Raw, JAM image files, System 7 Sound, AU,
MP3, and AAC/mp4.
New audio documents created with the Batch File
Processor will have the same file name as the original
input audio document and may also include an optional
suffix.

Input Area

Input Area

The Input Area allows you to enable or disable batch file
processing. Once the Batch File Processor is configured,
you may turn it on with the On button. If you have finished
batch processing and no longer need to batch process files,
you can use the Off button to disable batch file processing.

Process Area

Process Area

The Process Area shows two lists; the list on the
left, labeled Available Processes, allows you to
select processes that will be used in your batch
script. Almost every process that Peak is capable of
will appear in this list. The list on the right is
labeled Selected Processes For Batch and contains
the Peak processes in the current batch script.
Double-click on a process in the Available
Processes list to add it to the Selected Processes
for Batch list. Alternatively, click on a process in
the Available Processes list and then click the Add
>> button. To remove items from the Selected
Processes for Batch list, click on the items and
then click on the << Remove button.

You can include/exclude mono or stereo files from the
batch process by using the Process All Files, Only Mono
Files, and Only Stereo Files buttons. Process All Files is
the default setting. To have Peak’s batch processor only
work with mono files, click the Only Mono Files button.
Similarly, to only process stereo files (excluding mono
files), engage Only Stereo Files.

When you add a process to the Available Processes
list, you may be required to supply settings for the
process. The front-most audio document and
selection will be used for any previewing the
process may support. Peak’s batch processor
allows you to use multiple instances, or
occurrences, of a single process – each with its
own settings.

If you are going to process both stereo and mono
audio documents, open a stereo audio document
and make a selection before configuring the batch
processor. This will allow most processes to make
the correct decisions on how to process both mono
and stereo input files using the Batch File
Processor.

You may also specify which part of the file to apply
the process to. Once a process has been added to
the Selected Processes for Batch list, you may use
one of the buttons Entire File, Apply Just To First x
Seconds, or Apply Just To Last x Seconds. Use
these buttons to configure how to apply the
selected process to an audio document. For
instance, if you are using a Fade In process and

226

Peak 5 User’s Guide

only wish to apply it to just the first three seconds
of the audio document, click the Fade In process
from the Selected Processes for Batch list and then
type a “3” into the Apply Just to First x Seconds
edit text field. All processes are applied by default
to Entire File unless you configure the process
otherwise.

it is enabled. This is useful because any errors Peak
encounters during batch file processing will not require
user attention during processing. However, Peak will
issue a System Beep sound if an error occurs during
Batch File Processing. If this happens, check the log file
for errors.
Preserve File Attributes

Save Changes Area

Save Changes Area

Use the Save Changes Area to configure how your
audio documents will be stored after they have
been processed using your batch script. Click the
Set button to specify the output document format,
settings, and location.

If you wish to process a group of files with a variety
of attributes, such as file formats, bit depths, etc.
and have the processed files retain their original
attributes, click this box to enable file attribute
preservation. This option allows the Batch File
Processor to focus on all the available DSP
processes, rather than on file format (and other
attributes) conversion. If you wish to process a
group of files and also change them all to the same
output format, leave this box unchecked, and
select the desired output format by clicking the Set
button in the Save Changes area of the Batch File
Processor.

9

File Name Suffix

After clicking Set you will be asked to provide the
output file format, bit depth, and compression
options using the Save As dialog described in
Chapter 4. Choose which folder to save the
processed audio files into with the Save As dialog.

If you want the output audio files of your Batch
Process to be appended with a suffix, such as .WAV,
simply enter the suffix you want appended in the
File Name Suffix field. All resulting audio file
names will be appended with the suffix you specify.

Log File

You can create a text Log File during batch processing to
keep track of which files have been processed. This is
useful for lengthy batch processing sessions where the
possibility of a power failure or other circumstance could
prevent the batch process from completing. Click on the
Log File checkbox to specify that a log file should be
created for the batch process. After turning the Log File
feature on, Peak will ask you to provide a destination for
the log file. The log file can be viewed using TextEdit or
any application that can view text files. The Batch File
Processor will divert any error messages to the log file if

Make sure that the output directory ( folder) is
not set to the input directory or Peak’s Batch
File Processor may get caught in a loop. Peak’s
Batch File Processor does not support
overwriting input files.

Save Script

Peak allows you to save your batch script into a
settings file that can be recalled later. This feature

Chapter 9: Batch File Processor & Apple Events

227

is useful if you frequently process files using a
specific sequence of processes. After configuring
the Batch File Processor, click Save Script to save
your batch sequence into a Batch Script file. You
will be prompted to choose a save location and
name for the batch script. The settings file holding
your batch script will store the processes, each
process’ settings, and the output file format.
Load Script

To recall a batch script settings file that was stored
using the Save Script button (as described above),
click Load Script button. For example:
To convert a folder of files into AIFF IMA 4:1 files
Normalized to 95% with a Log:

1. Choose the Batch Processor command from
the File menu.
2. Double-click the Normalize item in the
Available Processes list. Enter “95” in the
following normalization settings dialog.
3. Click Set in the Save Changes Area of the
Batch File Processor. Choose AIFF from the
File Format pop-up menu. Choose IMA 4:1
from the Compression pop-up menu.
4. Choose the folder to save the output files
into. Click Save.
5. You will be back in the Batch File Processing
dialog. Click Log and choose the output
folder to save the log file into.
6. Click the On button in the Input Area of the
Batch File Processor.
The Batch File
Processor is now turned on.
7. Click OK to close the Batch File Processor
dialog.
228

8. Switch to the Finder, and drag and drop a
folder full of audio documents onto the Peak
application’s icon.
9. Peak will process all audio files in the folder
that was dropped onto the Peak application
icon.
10. Once the files have been processed, open an
audio document, choose the Batch Processor
command from the File menu. You may then
turn off the Batch File Processor by clicking
Off in the Batch Processing dialog.

Errors and Cancelling Batch Processes

Any errors during Batch File Processing will
produce a System Beep to notify you of the
trouble. If an error occurs during Batch File
Processing, Peak will not place an error dialog on
the screen. This happens so that processing can
continue. If you have specified that you wish to
create a log file, error messages that would appear
in an error dialog will appear in the log file,
indicating where in the batch file process the error
occurred.
Once the batch file processor has started, it will
continue to process files as quickly as possible. If
you find it necessary to halt the batch process,
press  -Period. A dialog will appear allowing you
to cancel the batch process. If you choose to
cancel the batch process, Peak will finish
processing the current file and then ignore any
other files to be processed. Once batch processing
has been cancelled, Peak will turn the batch file
processor Off.

odoc (Open Document)

The “odoc” event instructs Peak to open an audio
document with the document path provided in the data
following the event.
quit (Quit Peak)

Peak understands a vocabulary of Apple Events. Apple
Events can automate procedures for you, such as
triggering the playback of an audio document.
The standard suite of Apple Events that “savvy”
applications must understand includes the “odoc” (open
document) event. For example, when you double-click
on a Microsoft Word document, the Macintosh Finder
sends an “odoc” Apple Event to the application Microsoft
Word. Unfortunately, “odoc” requires the complete
document path of the document you wish to open. You
can use “odoc” with Peak, but Peak has another feature
that makes opening and playing your documents much
easier: simplified document descriptions instead of
entire document paths. To illustrate this difference,
compare the following:
Full Document Path:

The “quit” event Quits Peak.
Peak has its own class of events that it understands, all of
which have the ID “furp.” This class descriptor must be
present for Peak to understand the events you send to it.

when providing a simplified document path. When
specifying volumes, don’t use colons in the name of the
volume.

document is not found, Peak will beep once.

Below is an example Script Definition from FileMaker Pro
that might be used to create a Play Button. There are six
steps to this Script Definition:

stop (Stop any currently playing audio)

The “stop” event takes no additional data and instructs
Peak to stop playing any audio that is currently playing.

1. Stop any currently playing audio documents
(STOP).
2. Close any open digital audio windows (CLOS).

clos (Close the front-most window)

The “clos” event takes no additional data and instructs
Peak to close the front-most window, if one exists.

3. Pass the FindFile Volume name to Peak from some
FileMaker Pro field (SFFV ).
4. Pass the FindFile File name to Peak from some
FileMaker Pro field (SFFF).

play (Play the front most window)

The “play” event initiates playback of the front most opened
audio document. Use the “stop” event to stop playback, or wait
until the document completes it’s playback.

5. Tell Peak to find and open the document described
by steps 3 and 4, above (OFFF).
6. Tell Peak to Play the front-most audio document
(PLAY ) (opened in step 5).

Example Scripts

The FileMaker Pro documents included in the Peak Extras
folder are intended to illustrate Peak’s functionality in an audio
document database environment. To try out the scripts, open
one of the FileMaker Pro documents, type in the Volume
Name (the exact name of the hard disk the audio document
resides on) and Document Name for an audio document on
one of your hard drives, hit Enter and press the graphic play
button. If the document is found, Peak will play the audio
document. You can create new records with the -N
keystroke from FileMaker Pro to get a new empty record.

FileMaker Pro is not included with Peak.

well as loop start and loop end offsets for each. To
adjust loop point offsets, select Sampler from the
Preferences dialog.

Working with SMDI Samplers

SMDI Samplers, such as the Kurzweil K2500 or the E-mu E-IV,
use SCSI to transfer samples between devices. In order to
transfer samples between the Macintosh and your sampler using
SMDI, you must connect a SCSI cable between your Macintosh
and the sampler. Consult your sampler’s owner’s manual for
instructions on how to connect the cable to your Macintosh with
proper termination. Always use high-quality SCSI cables to avoid
data transmission errors.
Peak allows the user to turn fast Asynchronous SCSI
transfers On or Off in the Sampler dialog. Turn
Asynchronous transfers OFF if you are having trouble
transmitting samples to a SMDI device, or if your
Macintosh does not support Asynchronous SCSI transfer
To use the SMDI Sampler dialog:

Macintosh with a SCSI cable, try the following:
•

Make sure your SCSI cables are properly
connected. SCSI cables can come loose if they are
not tightened down using the cable’s connector
screws. Make sure you connect the SCSI cables to
your Macintosh only when it is turned off.

•

Make sure there is not another SCSI device
connected to your Macintosh using the same SCSI
ID as your SMDI device. Consult your SMDI
device’s owner manual for information on how to
change the SCSI ID of your SMDI device.

•

You may need to turn on your SCSI devices in the
correct order. Turn all of the SCSI devices
connected to your Macintosh on first, then turn on
the Macintosh and launch the Peak application.

A note about the Yamaha A3000
Peak supports the Yamaha A3000 digital sampler. You
can access the A3000 sampler using either the Yamaha
A3000 or SMDI menu selection under Peak’s Sampler
menu. Please note the A3000 cannot replace existing
samples, and any transfers to the A3000 will be placed in
the next available empty sample in RAM, regardless of
where you instruct Peak to place the sample. When
“BulkProtect” is turned on, the A3000 does not respond
to SMDI messages. “BulkProtect” is at UTILITY
mode>MIDI function>Bulk page. BulkProtect is
always ON after you turn on the A3000, so you will need
to turn it off before you can do SMDI transfers.

You can access the Sampler Preferences from Peak’s
Preferences dialog to set Loop Offsets and Asynchronous
SCSI transfer.

Introduction
This chapter explains each of the commands found in
Peak’s menus. For step-by-step instructions on
implementing these commands, refer to the index, and
go to the appropriate chapter where use of the
command is covered.

About Peak...

This menu shows information about the particular
version of Peak you are using, including the exact version
number and your serial number.

Peak allows you to customize the colors used to
display the elements in audio documents. You can
use this dialog to set the background color,
waveform color, and colors for markers and loops.
You can select either a preset color combination,
individual colors for each element in the audio
document window, as well as picking your own
custom colors from a color palette. Changes made
using the Colors dialog affect both the current
audio document’s colors, and any subsequent new
audio document’s colors. See Chapter 3 for more
information on this feature.

Chapter 11: Peak Menus

239

Blending

The Document Colors dialog

Scratch Disks

Because audio data can be very large, Peak utilizes a portion of
your hard disk’s free space to hold audio documents that have
been cut or copied, as well as for temporary or “scratch” files for
undo purposes. If your hard disk is short on space, you may not
be able to cut, copy, or modify large selections. If you have more
than one hard drive attached to your Macintosh, the Scratch
Disks command in the Preference menu allows you to choose
the hard drives (or “scratch disks”) that you wish to use for these
temporary files. Peak allows you to select which disk you want
to have as your default, or “Primary” disk for this purpose-usually
you would select the disk that has the most free space. If you are
connected to a file server, you can utilize available storage on the
server by clicking the Allow Servers checkbox. Any available
servers will then appear in the Scratch Disks pop-up menu. This
feature is recommended only if you have access to a high speed
Ethernet, or other fast server.

Blending is an automatic crossfade function with a usereditable envelope. Peak can apply blending to areas of
an audio document when they are modified by cutting,
pasting or other editing processes in order to smooth
abrupt transitions between waveform amplitudes. It can
be very useful for creating a smooth transition between
edits that would otherwise sound too abrupt. If are
going to cut, paste, or insert audio into a document, you
may wish to enable blending to smooth things out a bit.
It can be toggled on or off by clicking the Blending
button in the Audio Document Window, or pressing the
Caps Lock key on your keyboard. For detailed
instructions on how to use blending or how to edit the
blending crossfade envelope, see Chapter 5: Editing.

The Blending dialog

Auditioning

Peak’s Auditioning command allows you to audition a
selection along with a specific amount of audio
preceding or following it. The Auditioning dialog allows
you to select a desired amount of Pre-roll or Post-roll
when you play the selection.

Fade In Envelope

The Fade In Envelope command allows you to edit
Peak’s fade-in envelope. Fade-ins can be very useful for
smoothly fading into an audio document, or for fading
into one type of audio material from another. Very short
fade ins can also be useful for smoothing or removing
clicks and pops in a recording. The Fade In Envelope
dialog allows you to control the exact shape of a fade in
by providing you with user definable envelope controls.

The Fade Out Envelope command allows you to edit
Peak’s fade-out envelope. Fade-outs can be very useful
for smoothly fading out of an audio document, or for
fading out of one type of audio material into another.
The Fade Out Envelope dialog allows you to control the
exact shape of a fade out by providing you with userdefinable envelope controls. For detailed instructions on
how to create fade out and edit their envelopes, see
Chapter 5: Editing.

Peak DSP Preferences allow you to set the size of
the “window” used in time shifting, and the quality
of sample rate conversion. A setting of 8 is
recommended for Sample Rate Conversion Quality,
(with 1 being lowest and 10 being the highest). A
setting of 30ms is recommended for the time
shifting window size – a lower setting is better for
simpler, monophonic sounds, and a higher setting
is better for more complex polyphonic.

Plug-Ins Envelope

This command allows you to apply plug-in effects
gradually according to the envelope you create in the
Envelope Editor dialog. This is very useful for varying
the intensity of effects over time.

Peak’s default Keyboard Shortcuts are listed in Appendix 1.
You may also customize the Peak Toolbar using the
Shortcuts & Toolbar dialog. Just scroll to a function in
the dialog list, and use the checkbox to toggle the icon
on and off. This allows you to group only the items you
use most frequently on the Toolbar for easy access.
Playback Master Volume

Peak provides a master volume control for audio playback. In the
Playback Preferences dialog, set Peak’s output volume to the level
that you desire by adjusting the slider or entering a number value
from 0 (silent) to 7 (loudest). If you are controlling your playback
volume with the volume control of your playback system, you will
most likely want to leave the output level set to 7.
Playback Buffer
The Shortcuts & Toolbar dialog

Peak allows you to control the amount of RAM the program uses
when playing back audio documents. In general, lower is better.
A playback buffer of 32k is a good place to start. If you are
experiencing clicks in your playback, working with fragmented
files, using processor-intensive real-time DSP, or are using a slow
hard drive, you may need a larger playback buffer setting.

LE

Customized Shortcuts & Toolbar are not available
in Peak LE

Window Buffer

Window Preferences

Peak also allows you to control the amount of RAM the program
uses to keep audio documents buffered in RAM. Use larger
values if you are working with a few large files, and smaller values
if you are working with many smaller files. Experiment to find
the best settings for your system and working style.
Shortcuts/Toolbar Preferences

Peak allows you to customize any Peak menu item with a keyboard
shortcut. To change your keyboard shortcuts, go to the
Preference menu and select the Shortcuts and Toolbar item.
Keyboard shortcuts are stored in a preference file in the directory:

Peak’s Window Preferences allow you to designate which
windows “float” above open documents. Use the
Floaters dialog to specify which windows (Toolbar,
Transport, Contents, Movie, or plug-ins) float or not.
Also contained in the Window Preferences dialog is a checkbox
for Live Document Resizing. Live Document Resizing scales an
audio document’s contents when the window is resized,
allowing you to see the audio waveform’s size change as you
change the size of the window. A check in the Live Document
Resizing box indicates that the preference is turned on – an
absence of a check indicates that it is turned off.

The POW-r dithering preferences dialog allows you to choose
which POW-r dithering algorithm is applied when saving files or
bouncing Playlists. For mono files, or stereo files with a narrow
stereo field (e.g., recordings of solo instruments), use POW-r 1;
for more stereophonically complex material, use POW-r 2; for
full-spectrum audio with a wide stereo field, use POW-r 3.

background. This is a useful command if you have several
applications open, and want to focus on working in Peak. Other
applications can be brought back into the foreground by clicking
on their icon in the Dock.
Quit Peak

New

This command allows you to create a new Peak
audio document. When you choose this command,
a submenu menu appears which allows you to
choose either a mono or stereo format for the new
audio document, or to create a Playlist document
or a new audio document from an open Playlist
document.

The Open command ( -O) allows you to locate
and open an audio document. Peak can open
audio documents in a variety of formats including
AIFF, Sound Designer II, WAVE, QuickTime, Raw,
System 7 Sound, Sonic AIFF, Paris, Jam Image, AU,
MP3, and MP4.

The Close All command (Option--W) closes all open
Peak audio documents. If you haven’t saved changes,
Peak will prompt you to do so before it closes the
documents. If you don’t wish to save any of the changes
you’ve made, Option-click on the prompt dialog’s Don’t
Save button.
Save

The Save command (-S) saves the current audio
document. Peak can save audio documents in a variety
of audio file formats including:
•

AIFF: This is Apple’s Audio Interchange File Format.

It is also Peak’s default file format and is supported
by many Macintosh software applications.
•

Sound Designer II: This is one of Digidesign’s audio

file formats for its digital audio products, which has
become popular in other audio applications. This
is a good format to use if you plan to use an audio
file in a Digidesign audio application.
•

This is Microsoft’s Windows Audio File
Format. It is supported by many Windows software
applications and most Macintosh applications. The
WAVE format is best if you plan to use an audio
document in an application that supports or
requires WAVE format files.

•

QuickTime:

244

WAVE:

Peak 5 User’s Guide

This is Apple’s audio file format for

QuickTime-based multimedia. It is supported by
all Macintosh software applications that support
QuickTime. The QuickTime format is best if you
plan to use an audio document in multimedia
applications that support QuickTime, such as Final
Cut Pro™ or Macromedia Director™.
•

Raw: This is the headerless raw file format that may
be useful for some game platforms.

•

System 7 Sound: This the Apple audio file format
used for Macintosh Operating System Sounds.

Save As

The Save As (Shift--S) command allows you to save a
copy of the current audio document under a different
name, in a different location on your hard drive, or in a
different audio file format. The saved copy will become
the active open audio document. You can save the
document with a variety of audio compression schemes.
For detailed instructions on using this feature, see
Chapter 3: Peak Basics.

The file format used by Sonic Solutions
audio workstations.

This is the file format used by E-mu’s Paris
audio system.
Jam image file:

This is the Jam audio image file
format. Jam audio image files may be created in
Peak and used in Roxio Jam for burning audio CDs.
(See Chapter 6: Playlists & CD Burning for more
information.)

.au:

This file format is commonly used on the
World Wide Web and in Java audio applets. .au is
supported by many platforms and programs.

MP3:

Saves audio as MP3 encoded audio.

Different formats allow different information to be stored
with the file. If you open a file created in a format other
than Peak’s default AIFF format, Peak will preserve any
format-specific information unless you save the file into a
different file format. Saving a file in a different format
than its original format, however, may cause some
information stored in the file to be discarded. For
instance, Sound Designer Regions cannot be stored in
QuickTime, AU, System 7, or MP3 files; nor can copyright,
author, or other file format-specific information be saved
in a format which doesn’t support it.

The Save As dialog

Save A Copy As

The Save A Copy As command (Option--S) allows you
to save a copy of the currently active open audio
document under a different name without replacing the
active open audio document.
Import CD Track

The Import CD Track command allows you to import
tracks from an audio CD. CD tracks imported to Peak
will be saved as AIFF files. For more detail on importing
CD audio with Peak, see Chapter 4: Playback &
Recording.

Import Dual Mono

The Import Dual Mono command lets you import two
mono files and create an interleaved stereo file. Certain
audio applications, such as BIAS Deck and Digidesign’s
Pro Tools, use “dual mono”, rather than stereo
interleaved files. Peak allows you to open such dual
mono files, and in the process creates a new stereo audio
document. Because Peak actually writes a new stereo
audio file to disk, this conversion process requires hard
disk space equivalent to the two original mono files. For
more information on opening dual mono files, see
Chapter 3: Peak Basics.

LE

the audio data location, and the byte order. With these
few bits of information (and depending on the degree of
damage), Peak may be able to recover many otherwise
unusable audio files. To attempt to recover a file, you
must supply correct information about the format the
file was originally recorded in, otherwise, you may end
up with white noise, or a file that plays at the wrong
speed, etc.
When the Recover Audio File encounters corrupt sectors
with media, file, or I/O errors, it will attempt to continue
recovering whatever audio data is available, and will write
the sections containing errors as silence in the new audio
file that is created.

Import Dual Mono is not available in Peak LE.

LE

Recover Audio File is not available in Peak LE.

Recover Audio File
Export Dual Mono

The Export Dual Mono command allows you to save a stereo
audio document as separate mono digital audio documents.
This feature is convenient if you intend to use the audio
document in a multitrack audio application, such as BIAS Deck
or Pro Tools, which does not directly support stereo audio files.
When you choose this command Peak will prompt you to name
both the left and right sides with a Save dialog.
Recover Audio File dialog

Export Regions

Peak 5 includes a new tool called Recover Audio File,
which allows you to open a damaged file, and attempt to
recover the audio data contained in it. This tool extracts
audio data only, and ignores all other information
contained in the file’s header, such as information about
loop points, regular markers, Region markers, etc. When
audio data is successfully recovered, it is placed into a
new audio document and must be saved.
There are a few pieces of information that Peak requires,
in order to attempt file recovery – these include the
number of channels, the file’s bit depth and sample rate,
246

If you have placed markers or Regions in an audio
document, Peak’s Export Regions command allows you to
save each of these Regions as a separate audio document.
This feature is very convenient if you wish to divide a larger
file into Regions and transfer them as samples into a
sample playback instrument, or divide a live concert record
into Regions and export those Regions as separate files.
Furthermore, you can use Peak’s Batch File Processor to
process a file’s Regions with any of Peak’s DSP functions
and third party plug-ins during the automatic exporting of
Regions into new files. For more information on exporting
Regions, see Chapter 5: Editing.

Peak 5 User’s Guide

To use Batch File Processing, go to the File menu and select
Batch Processing. The Batch File Processor dialog appears.
Peak’s Batch File Processor is split into three areas: Input,
Process, and Save Changes. Sequence a series of steps
for Peak to execute in the Process section, then set your
output file settings in the Save Changes area. Once
Peak’s Batch File Processor is configured, you may turn
on the Batch File Processor in the Input area.
The Export Regions dialog

LE

Export Regions is not available in Peak LE.
However, Regions may be dragged from the
Contents Window to the Finder as discrete files.

Export as Text

If you wish to keep a text record of your Playlist, you may
export the Playlist into a new text document. The text
document will show names, times, crossfade times, and
gain levels of each Playlist Event.

Once the Batch File Processor is configured and turned
on, any files you drop onto the Peak application’s icon
(or an alias) will be batch processed according to your
settings. You can even drop folders or disks onto Peak’s
icon and all of the supported audio contents will be
batch processed. You can continue dropping files, folder,
or disks, onto the Peak icon for batch processing while
the Batch File Processor is turned on. All subfolders or
disks you drag onto the Peak application for Batch File
Processing will be recreated in the Batch File Processor’s
output directory, preserving all organization of your files.
Audio documents opened using the Open command
from the File menu will not be batch processed.

LE

Batch Processor

Peak’s Batch File Processor is one of the most powerful,
versatile, and useful features in Peak. Using the Batch
File Processor, you can integrate any series of Peak
processes (called a batch script), and apply these scripts
to any number of audio files.

Batch File Processor is not available in Peak LE.

Burn Audio CD

Choosing the Burn Audio CD will burn the foreground
audio document as an audio CD. If Regions are
contained in the document, Peak will prompt you as to
whether these should be used to designate different
tracks on the finished audio CD.
Recently Opened Documents

Batch File Processor

Peak automatically remembers the last several
audio documents or Playlists that you have opened
and keeps a list of these at the bottom of the File
menu. This allows you to easily select a
document’s name and reopen it without having to

search for it on your hard drive. Peak can also find
and open a document even if you have changed its
location on your hard drive. And if you change the
name of the file, the next time you open Peak, Peak
will automatically update the name in its internal
list.

Edit Menu

Redo

The Redo command (-Y ) “undoes” the undo
command. If you wish, you can continue redoing actions
until there are no items left to redo. In this case, the
Redo command will be unavailable and appear grayed
out. The only limitation in using the Redo command is
that if you insert a new action when a redo action is
available, you will no longer be able to redo. In other
words, as soon as you perform an editing action other
than Undo, Redo is no longer available
Edits

This menu contains all of the standard Macintosh
commands for cutting, copying, and pasting, as well as
several other commands specific to Peak.

The Edits command provides you with a second unique
and powerful “unlimited undo” feature. You can think of
the Edits command as a kind of “random access” undo with
a list of all your editing actions since you last saved. Using
this list, you can navigate back in time to the point at which
you performed a particular edit, and if you wish, undo it.
Once you have returned to an earlier state in the project,
you are free to start editing from that point on, if you wish.
Be aware that if you do go back to a past action and
perform a different action at that state in the project, any
edits that originally followed will be gone and you won’t
be able to redo them.

Undo

The Undo command (-Z) undoes the last action that
you performed. Since Peak features unlimited undo and
redo capability, repeatedly choosing this command will
undo each action that you have performed on your audio
document. If you wish, you can continue undoing
actions until you return to the original state of the audio
document. When there are no actions left to undo, the
Undo command will be unavailable and appear grayed
out.
248

The Edits dialog

Cut

The Cut command (-X) cuts selected data from an
audio document and copies it to Peak’s Clipboard. Once
you have cut a portion of an audio document, you can
paste it or insert it at another location in the same
document or a different document.

Peak 5 User’s Guide

Copy

The Copy command (-C) copies selected audio into
Peak’s Clipboard. Once you have copied a portion of an
audio document, you can paste it or insert it at another
location in the same document or a different document.
Paste

The Paste command (-V ) allows you to paste the
contents of the Clipboard into a location that you choose
by placing an insertion point. Pasting audio deletes any
selected audio and inserts the clipboard audio at the
insertion point.
Replace

The Replace command allows you to paste audio from
Peak’s Clipboard over existing audio, without pushing all
data to the right of the insertion point farther to the right
(later in time) to accommodate the newly pasted audio.
Duplicate

The Duplicate command has a number of different
behaviors, depending on whether you are working in an
audio document or in a Playlist. More information about
this command is available in Chapters 5 & 6.
If no selection is made when this command is invoked,
the Duplicate command allows you to paste multiple
copies of audio data into an audio document without
overwriting any existing data at the insertion point.
When you paste data with the Duplicate command, all
data to the right of the insertion point or selection start
is pushed farther to the right (later in time) to
accommodate the newly pasted audio. The Duplicate
command allows you to specify how many times you
would like to Duplicate the audio data contained in the
clipboard. The Duplicate command is very useful for
creating longer audio documents that need to repeat a
certain piece of audio, such as creating a 4 bar drum loop
out of a 1 bar drum loop.

If there is a selection in the waveform when the
Duplicate command is invoked, then Peak automatically
fills the selection with the Clipboard contents. Peak
determines how many times the Clipboard contents
must be duplicated in order to fill the selection. If the
selection is not evenly divisible by the duration of the
Clipboard contents, Peak includes a fraction of the
Clipboard contents to make the duplication completely
sample accurate to the original selection.
Insert

The Insert command (-D) allows you to paste audio
into an audio document without overwriting any existing
data at the insertion point. When you paste data with the
Insert command, all audio to the right of the insertion
point or selection start is pushed farther to the right
(later in time) to accommodate the newly pasted audio.
Insert Silence

The Insert Silence command allows you to insert a
specific amount of silence into an audio document at the
current insertion point. When you choose this
command, Peak will prompt you to enter the amount of
silence you wish to insert. You can enter this value in
Samples, Milliseconds, or Seconds. All audio occurring
after the insertion point is moved later in time by the
amount of the silence that you insert.

The Clear Clipboard command allows you to free
up disk space occupied by the contents of the
clipboard if you no longer need the audio
contained there.
Select All

The Select All command (-A) selects all audio in the
audio document.
Insertion Point at Selection Start/End

The Insertion Point at Selection Start command (Up
Arrow) places the insertion point at the beginning of a
selection. The Insertion Point at Selection End
command (Down Arrow) places the insertion point at
the end of a selection.

The Select Loop command (-”-”) will automatically
select the audio within the loop start and loop end
markers, if you have defined a loop in a document.
Previous Selection/Next Selection

If you have made a selection in an audio document, then
made another selection, you can use Previous Selection
(-Shift-Left Arrow) to jump back to the previous
selection. You can then use Next Selection (-ShiftRight Arrow) to jump ahead again. This works for
multiple selections.

Action Menu
This menu provides several commands for zooming in
and out of the audio document window, creating loops,

250

Peak 5 User’s Guide

markers and Regions, and navigating to specific locations
in an audio document.

Increase Vertical Zoom

The Increase Vertical Zoom command (Control-Up
Arrow) makes the waveform “taller,” or increases the
vertical zoom. The Increase Vertical Zoom command is
useful for obtaining a better “big picture” view of quieter
audio material.
Decrease Vertical Zoom

The Decrease Vertical Zoom command (Control-Down
Arrow) makes the waveform “shorter,” or decreases the
vertical zoom.
Fit Selection

The Fit Selection command (Shift--]) will zoom the
view so that your selection fills the audio document
window.
Zoom Out

Zoom Out All the Way

The Zoom Out command (-[) zooms the waveform
view out allowing you to see more of the entire
waveform, but in less detail. The Zoom Out command is
useful for obtaining a better “big picture” view of audio
material. To zoom progressively out from a waveform,
select this command repeatedly or press -[ repeatedly
on your computer keyboard.

The Zoom Out all the way command (Shift--[) zooms
the audio document window to show an overview of the
entire audio document.

Zoom In

The Zoom In command ( -]) zooms the waveform
view in so that you can view audio data in greater
detail. The Zoom In command is essential when
you wish to select and edit audio with great
precision. To view a waveform in progressively
greater detail, select this command repeatedly or
press  -] repeatedly on your computer keyboard.
Holding down the Option key while you make a
selection will zoom the waveform view in so that
your selection fills the audio document window
after you release the mouse button.

Zoom at Sample Level

The Zoom at Sample Level command (Shift-Left
Arrow) zooms the audio document window to the
single-cycle level, allowing you to view the
waveform a single sample at a time. This is useful
for drawing on the sample with a pencil tool, or
fine-tuning loops and markers.
Zoom at Sample Level (End)

The Zoom at Sample Level (End) command (ShiftRight Arrow) zooms the audio document window
to the single-cycle level and places the insertion
point at the end of the audio selection.

Snap To

Snap Start

This command will cause new selections in the
audio waveform to move, or “snap” to the nearest
selected Snap To unit. The Snap To units available
are listed below:

This command will cause the beginning of the
current selection to move to the nearest selected
Snap To unit.
Snap End

•

Zero Crossings

•

Bars/Beats

•

CD Frames (588 samples or multiple thereof )

•

Sony PS2 Loop Boundaries (28 samples or multiple
thereof )

This command will cause the end of the current
selection to move to the nearest selected Snap To unit.

•

Microsoft Xbox Loop Boundaries (64 samples or
multiple thereof )

•

Custom Units (allow entry of a user-definable
number of samples)

The Snap To units you choose will depend on the
type of editing work you will be doing. Most users
will probably use Zero Crossings or Bars/Beats for
most musical applications. Multimedia and video
game sound designers will especially appreciate
these new options when producing audio for a
particular delivery platform. For example, when
creating audio loops and sound effects for a
Playstation 2 video game, audio edits need to be
made at increments of 28 samples in order to
loop/play back smoothly in the PS2’s audio engine.
By choosing the Snap To PS2 loop boundary
setting, any edits that are made will automatically
be made in units that will translate smoothly to the
PS2’s playback system.
Snap Start & End

This command will cause the beginning and end of
the current selection to move to the nearest
selected Snap To unit.
252

Loop This Selection

The Loop This Selection command (Shift- -”-”)
automatically creates a loop from the current
selection by placing loop markers on either side of
the selection. Since Peak supports a single loop
per audio document, choosing this command in a
document with a loop already defined will cause
the loop markers to move to the current selection.
Nudge Loop Backward

The Nudge Loop Backward command (Option-Left
Arrow) pushes, or “nudges,” the loop point backward.
This allows you to fine-tune the loop.
Nudge Loop Forward

The Nudge Loop Backward command (Option-Right
Arrow) pushes, or “nudges,” the loop point forward.
This allows you to fine-tune the loop.
New Marker

The New Marker command ( -M) creates a new
marker at the current insertion point in an audio
document. Markers are locations in an audio
document that you define as important. By
marking specific locations in a recording, you can
navigate easily to a location for selection, editing
or playback purposes.

Peak 5 User’s Guide

Once you have defined a marker, you can assign or edit a
number of its attributes with the Edit Marker dialog that
appears when you double-click the marker. This dialog
and the attributes contained within are explained in
Chapter 5: Editing.

New Region

The New Region command (Shift--R) defines a
selection as a new Region and adds it to the Regions
menu. Locate a Region by double-clicking the name of a
Region in the Contents Window. The audio document
will automatically scroll to display the selected Region,
and the Region will become the current selection in the
audio document. For more detail on Regions in Peak,
see Chapter 5: Editing, and Chapter 6: Playlists & CD
Burning.
New Region Split

The Edit Marker dialog

Markers from Tempo

The Markers from Tempo command will
automatically create markers at regular intervals
based on the tempo that is entered. To use
Markers from Tempo, you will either need to know
the tempo of the audio material you are working
with, or you can use Peak’s Guess Tempo feature to
figure it out. Place Peak’s insertion point in the
waveform at the point you wish to have the first
marker placed. Designate whether you prefer to
have markers placed every Beat or Bar, and then
indicate the duration for which you wish to have
markers placed. Peak will place markers either for
the duration of a selected range of audio, or you
can enter a specific value. Click OK to create
markers. Markers from Tempo is described in more
detail in Chapter 5: Editing.

When working with audio material with a
pronounced beat, it’s best to place the insertion
point just before a downbeat. This ensures that all
following markers will also be placed just before
beats for the duration you choose.

The New Region Split command will subdivide an existing
Region or audio document into two separate, back-to-back
sections, one on either side of the insertion point. To use
this feature, simply place the insertion point cursor within an
existing Region or audio document, and choose the New
Region Split command from the Action menu – the existing
Region or document is split into two sections at the point
where the insertion point was placed.
Capture Region to Playlist

The Capture Region to Playlist command (-K) will create a Region
based on a selection made in an audio document and automatically
enter it into a Playlist. This feature is very useful when you need to
quickly create Regions that will also be used immediately in a Playlist.
Markers to Regions

The Markers to Regions command will convert any
markers in a selection to Regions. If you make a
selection containing two markers, they will be
converted to one Region with the name of the first
marker. If you make a selection containing three
or more markers, the markers will be converted to
contiguous, butt-spliced Regions. For example, if
you have three markers named “Foo 1”, “Foo 2”,
and “Foo 3” and select them and apply Markers to
Regions, the resulting two Regions will be named
“Foo 1” and “Foo 2”-wherein the first marker has

253

11

become the begin Region marker of Region “Foo
1”, the second marker has become the end Region
marker of Region “Foo 1” and the begin Region
marker of “Foo 2”, and the third marker has
become the end Region marker of Region “Foo 2”.
Alternatively, hold the Option key down when
selecting the Markers To Regions command to
make each marker a Region that ends at the next
marker.

The Nudge dialog

Go To

The Go To command (-G) allows you to quickly and
precisely navigate to a the start or end of a selection, the
start or end of a loop, a specific marker, or a specific time
location in an audio document. This command is
essential for speedily locating any of these important
locations in an audio document. Choosing the Go To
Time command allows you to enter the exact time
location that you wish to navigate to. In addition, the
Location submenu lists all markers, Regions and loops.

Three Markers named “Foo”

The Go To Time dialog

Loop Surfer

Two Regions named “Foo”

Peak’s Loop Surfer feature (-J) automates some of the
steps for setting up loop points. Loop Surfer allows you
to “Loop Surf ” (adjust your loops during playback)
quickly, easily and in a musically intuitive manner.

Nudge

The Nudge command allows you to nudge all
marker, loops and Regions in the current audio
document selection by the number of seconds
entered in the Nudge Markers dialog. Type either
positive or negative numbers, and Peak nudges the
marker by the value you entered in the dialog.

254

If you’re working with music, and know the music’s
tempo in beats per minute, you can use Loop Surfer to
create a loop which lasts for a rhythmically “correct”
length of time. For more detail regarding Loop Surfer,
see Chapter 5: Editing.

If you are working with music and don’t know the tempo-and
your music has a relatively pronounced or obvious beat-you can
use the Guess Tempo command to have Peak automatically
guess the tempo of a selection. Make a selection and choose
Guess Tempo from the Action menu. There will be a pause
while Peak scans your selection and calculates the tempo for
you. A dialog will then appear showing you the estimated tempo
in BPM, or beats per minute. You can then enter the estimated
tempo in BPM in the Loop Surfer dialog’s Tempo field or in the
Audio Information dialog’s Tempo field or press the Loop It
button to create a loop at the current insertion point with the
detected BPM.

The Play/Pause command (Spacebar) starts playback of
the audio file from the insertion point or pauses
playback.

Auto Gain Control checkbox

Record timer checkbox

The Auto Gain Control checkbox allows you to disable
the Automatic Gain Control feature used by the Mac OS
X Audio HAL (Sound Manager) system with some
Macintosh microphone inputs. Auto Gain Control
adjusts input gain automatically to get maximum
recording levels. If the recording device you are using
supports this feature, check the Auto Gain Control
checkbox.

The Record timer checkbox allows you to designate a
specific duration for recording. Peak will stop recording
after this set time and bring up the Save dialog for your

Monitor checkbox

The Monitor checkbox allows you to monitor the audio
source while you are recording.
Split Stereo Files checkbox

The Split Stereo Files checkbox allows you to record the
incoming stereo audio as dual mono files rather than a
single stereo file. Dual mono files are used in programs
like Digital Performer, Pro Tools, or BIAS Deck, so this
option is useful if you need to record dual mono files
(i.e., split stereo).

The Recording Time dialog

Open after saving checkbox

The Open after saving checkbox determines whether the
audio document is opened in Peak after it is recorded.
Device and Sample Format button

The Append to document checkbox allows you to record
into an existing audio document. To record into an
existing audio document, place the insertion point in the
existing audio document at the point where you want to
insert the new audio. If the insertion point is at the
beginning of the file, the newly recorded audio will be
inserted at the beginning of the file. If the insertion
point is at the end of the file, the newly recorded audio
will be appended to the end of the existing file. If the
insertion point is somewhere in the middle of the file,
the newly recorded audio will be inserted at that point.
If you make a selection, the Append to document feature
will allow you to replace the selection with newly
recorded audio from the beginning of the selection
through the end of the selection or wherever you stop
the recording.

Auto Define Tracks

Amplitude Fit

Amplitude Fit provides granular normalization of an
audio selection on a grain-by-grain basis. Grains are
small groups of samples, often around 30ms. As each
grain is read in, it is normalized according to the
Amplitude Fit Envelope-each normalized grain
crossfaded with the previous grain and written out as the
result. Amplitude Fit can be used to maximize the
volume level of an audio selection, or to make quiet
passages as loud as louder passages.

The Auto Define Tracks tool allows you to automatically
split audio recordings into separate Regions, each of
which will become an individual CD track when an audio
CD is burned. This tool is useful for quickly editing LP
and cassette recordings, in preparation for burning them
to CD.
This DSP tool works by automatically placing Region
markers into an audio document based on audio level,
minimum period of silence between songs, and
minimum song duration. Peak analyzes the audio levels
throughout a document, and places Region markers
around each song. The louder parts are considered to be
songs, and the quieter parts are the gaps between them.
Since some songs may contain very quiet parts that could
mistakenly be interpreted as gaps between tracks, a few
parameters are available to help Peak correctly
distinguish between songs and the gaps between them.
Minimum Silence Between Tracks

The Amplitude Fit Envelope editor

LE

Amplitude Fit is not available in Peak LE.

This field is used to enter the minimum gap time
between songs in the audio document you are working
with. If a recording you are working with contains two
second gaps between each song, start with the default
value of “2.00” in this field. If the gaps between songs
vary in length, enter the value of the shortest gap in the
entire recording.

Chapter 11: Peak Menus

259

11

If you need to measure the gap time between songs,
activate the Cursor Info overlay by selecting Show
Cursor Info (-Shift-T) from the Options menu, and
then select the gap between songs in the audio
waveform – the Cursor Info overlay will tell you the
length of the selected area. You may also need to set
your preferred Time Units to Min:Sec:ms – this can be
done in the Options Menu>Time Units.

Minimum Track Duration

Peak needs to have some information about the length of
each song, in order to accurately divide a long recording into
individual songs. The Minimum Track Duration parameter
tells Peak how long the shortest song in a recording is, and
helps ensure that Region markers are placed in the correct
location in the audio waveform – that is, a begin Region
marker just before a song starts, and an end Region marker
just after a song ends – even if the audio level falls below the
threshold value set with the Silence is Audio Below slider (see
next section). If a recording you are working with contains
songs that are all approximately 4-5 minutes long, a good
value to enter in this field would be 240 seconds (4 minutes).

Number of Songs field

This numerical field is tied to the Silence is Audio Below
slider, and displays the number of songs that Peak
automatically detects in a recording, based on the
settings used for Minimum Silence Between Songs,
Minimum Track Duration, and Silence is Audio Below.
Depending on the settings you choose, Peak will detect
a different number of songs, and this field will display
different numbers. When the Silence is Audio Below
slider is moved, the number of songs detected will
update, and typing in a new value in the Number of
Songs field will update the Silence is Audio Below slider.
Typically, the automatic number of songs detected is very
accurate, provided you have entered accurate settings
for the other parameters that define tracks. There may
be times however, where Peak detects more or fewer
songs than the recording actually contains. You may
choose to define the number of tracks using the Silence
is Audio Below slider, or by typing in a known number of
songs in the recording, and then fine tuning with the
Silence is Audio Below slider. Be aware that the values
you enter in the Number of Songs field, and the values
you set with the Silence is Audio Below slider may
override each other. More information about Auto
Define Tracks is available in Chapter 7: DSP.

Silence is Audio Below slider

Bit Usage

This slider controls the threshold level between audio
material you wish to define as a Region and the gaps
between it. As this slider is moved, you will notice Region
markers appearing in the audio waveform in the
background, and you will also notice the value in the
Number of Songs field changing. (More information on the
Number of Songs field is in the next section). For example,
if you are working with a recording from a cassette, the gaps
will typically contain hiss or other noise that is not
completely silent, but has a significantly lower amplitude
level than the program material that you are trying to isolate
into tracks. By adjusting the Silence is Audio Below slider,
you can make the judgment as to what should be silence,
even if it does contain some low level audio such as tape
hiss, or other background noise.

The Bit Usage meter allows you to monitor bit saturation,
degradation, and the "true" bit depth of a file.

Change Duration

The Change Duration command allows you to slow
down or speed up the selected material by a specified
amount without changing its pitch. You can specify the
change in duration by a value in seconds, a percentage of
the original, or, for rhythmically-oriented material, beats
per minute. A change in duration by a reasonable
amount, about 85% to 115%, can be very convincing.
Exaggerated time stretching, 200% or more, can result in
some very interesting granular textures.
Try
experimenting with the Change Duration function on
drums, rhythm loops, speech, sampled instruments or
sound effects to achieve a wide variety of useful effects.

The Change Gain dialog

Change Pitch

Peak’s Change Pitch function allows you to alter the pitch
of an audio selection by as much as an octave. The
Change Pitch dialog uses a pitch slider that allows you to
choose a new pitch by musical interval, and “fine tune”
the pitch change by smaller increments called “cents.”
(Cents are divisions of a musical octave-one octave is
equivalent to 1200 cents-thus, 100 cents is a semi-tone,
50 cents a quarter-tone, etc.) You can also choose to alter
the length, or duration, of the selection just as you would
by slowing down or speeding up analog tape, or you can
choose to preserve the duration of the selection
(something not possible with analog tape!).

The Change Duration dialog

Change Gain

The Change Gain function changes the gain (i.e.,
amplitude) of a selection. You can specify the amount of
gain change either in decibels (dB) or as a percentage. If
you wish to double the volume of a sound, you must
apply approximately 6 dB of gain change, or add 200%.

Convert Sample Rate

Crossfade Loop

The Convert Sample Rate command allows you to
change the sample rate of a sound without changing its
pitch. This feature is very useful for converting audio
material into lower or higher sample rates as required by
other applications. Please note that sample rate
conversion is applied to an entire document. It cannot
be applied to just a selection within a document. Refer
to Chapters 3 and 4 for an explanation of commonly used
sample rates.

The Crossfade Loop function applies a “smoothing”
effect to loops made in Peak audio documents.
Crossfade Loop fades the end of the loop into the
beginning of the loop to make the loop sound smoother.
(It uses the Blending envelope you’ve set in Peak’s
Preference menu’s Blending dialog.) Use the Crossfade
Loop dialog to select the length of the crossfade in
milliseconds.

Peak LE is limited to a maximum sample rate of 96kHz

The Convolve command is a unique and powerful sound design
tool that allows you to apply the sonic (e.g., spectral)
characteristics of one sound onto another. Convolution works
by multiplying the frequency spectrum of the impulse contained
in the clipboard and that of the target audio document,
reinforcing the frequencies that are in common between the
two. To use the Convolve DSP command, you must first copy a
selection of audio. The copied material will provide the spectral
“character” that you will apply to the target audio material.

imagine a piece of music that has a specific type of fade
out, and you would like to be able to apply that fade out
“envelope” to other pieces of audio. By selecting the
entire fade out, and then using the Envelope from Audio

characteristics, and save them as an envelope that can
later be recalled in any of Peak’s envelope based tools,
such as Fade In/Out, Gain Envelope, etc. Once an

tool. For a more precise envelope, where more points
define the shape, enter a smaller value in milliseconds in
the “ms” field (or use the slider). For a less precise (or
“smoother”) envelope, where fewer points define the
shape of the envelope – use a larger value.
Fade In & Fade Out

The Fade In and Fade Out commands allow you to apply
an amplitude envelope to an audio selection. The Fade
In and Fade Out DSP commands, and the Fade Envelope
Editor dialog are described in detail in Chapter 5: Editing.
Find Peak

The Find Peak operation will place the insertion point at
the sample with the maximum amplitude value that it
locates in the audio selection.

LE

Harmonic Rotate

The Harmonic Rotate tool is excellent for sound design
experimentation. This command allows the frequency
spectrum in a selected range of audio to be rotated
around a horizontal axis, which has the effect of taking
frequencies that were previously associated with one
section of a file with a particular amplitude, and assigning
them to different areas of audio with different
amplitudes. The Harmonic Rotate command can be
previewed in real time, so that desired setting can be
found before spending time processing. Options for
processing include checkboxes for using Real &
Imaginary calculations, and a slider & text field to set
amount of rotation.

ImpulseVerb

ImpulseVerb™ is an extremely high-quality reverb
processing tool, that utilizes actual reverb impulses
recorded in real spaces, such as performance halls,
catherdrals, caves, and other spaces that have various
reverberation qualities.
The same convolution
technology that is used in Peak’s Convolve DSP tool
allows these natural reverb impulses to be applied to dry
audio signals, giving the impression that a file was
actually recorded in a particular environment.
ImpulseVerb offers real time preview, so that the ideal
settings can be found before processing. In addition,
ImpulseVerb offers an editable Space envelope, which
controls reverb length and decay characteristics, and a
Wet/Dry slider to control the amount of reverb being
applied.

Invert

The Invert function allows you to invert the phase of a
selection or an entire audio document.
Loop Tuner

Peak’s Loop Tuner provides a way to visually line up the
start and end points of your loop and listen to the effects
of these adjustments as you make them. The waveform
display in the Loop Tuner dialog shows the Start and End
points of the loop, which you can visually adjust with the
scroll bars at the bottom of the window to achieve a
natural transition at the loop point by carefully adjusting
the slope alignment. The arrows of the slider will move
the loop markers sample by sample and clicking in the
body of the slider will move the loop markers to the next
zero crossing. The two zoom buttons (magnifying glass
icons) in the upper left of the Loop Tuner dialog allow
you to adjust the vertical zoom up of the waveform. The
two zoom buttons in the lower left hand corner of the
Loop Tuner dialog allow you to adjust the zoom view in
and out all the way down to the sample level. You can
listen to the effects of the adjustments as you make them
by clicking on the Play button.

The ImpulseVerb dialog can also be used as a real
time convolution tool, and is not limited to using
impulse response files to create reverb effects. Any
selection that is copied to the clipboard can be
convolved with the selected range of audio. To
add audio files to the Space pop-up menu within
the ImpulseVerb dialog, simply save the desired file
as a 24-bit Sound Designer II format file, and

LE

Loop Tuner is not available in Peak LE.

Mono To Stereo/Stereo To Mono

These two DSP commands may be used to easily convert an
audio document between one and two channel formats.

The Mix command allows you to mix material that you
have copied to the clipboard with a target selection. This
function can be used as a kind of “sound-on-sound”
capability for mixing audio tracks together, or for
blending sound elements. The Mix command is similar
to the Add command, but it does not have the potential
to clip because the target and clipboard contents are
attenuated before mixing. To use the Mix command, you
must first copy a selection of audio. The copied material
can then be mixed into the target audio material.

Mono to Stereo Conversion dialog

The Mix dialog

LE

Mono To Stereo/Stereo To Mono is not available in
Peak LE.

While automatic Mono To Stereo/Stereo To Mono
conversion is not available in Peak LE, you can
achieve the same end result manually, by selecting
all in an open mono or stereo document, and
then opening a new, empty document. If you copy
an entire document, open a new empty
document, and attempt to paste in the contents of
the clipboard, Peak will detect if there is a different
number of channels, and will prompt you to enter
a Left/Right panning value, and will then allow
you to paste in the clipboard contents.

Modulate

This Modulate command functions as a “ring modulator”
which multiplies two audio signals together (e.g., the
material copied to the clipboard and the currently
selected audio). The resulting audio includes the sum
and difference tones of the frequency components of the
modulated audio and the modulating audio. These are
generally very complex timbres that often have a
“metallic” (i.e., inharmonic) character to them.

The Normalize (RMS) dialog

Normalize

This command allows you to optimize the volume of a
selection or an entire audio document so that it is at its
maximum possible amplitude without clipping. The
normalize function is very useful for boosting the volume
of material that was recorded at too low a level, or if used
on multiple audio documents, for ensuring that the
amplitude of each of the documents is uniform.

The RMS Normalize dialog offers two parameters – RMS
Level and Digital Ceiling. RMS Level allows you to enter
the desired RMS Level (or average level), and the Digital
Ceiling allows you to limit the maximum audio level,
which is also the level at which Soft Clipping will activate,
if the RMS Level exceeds it.
The RMS Normalize function is very useful for boosting
the volume of material that was recorded at too low a
level, or if used on multiple audio documents, for making
sure that the amplitude of each of the documents is
uniform.

LE

The Normalize dialog

Normalize (RMS)

RMS Normalize is not available in Peak LE.

Panner

This command allows you to optimize the volume of a
selection or an entire audio document so that it is at its
maximum possible amplitude without clipping. RMS
Normalization is based on the RMS (Root Mean Square),
or “average” signal level of the selected portion of audio.
The RMS value of a file cannot be increased to an
arbitrarily high value. If the desired RMS specified by the
user is so high that will produce clipping in the signal,
the Soft Clip feature will automatically activate and the
resulting RMS level will be lower than specified by the
user. The processed file will be as loud as possible while
guaranteeing that the signal will be limited to the ceiling
specified by the user.

The Panner allows you to adjust the panning, or left-toright movement, of a stereo document by drawing an
envelope in the Panner dialog. Left is at the top of the
graph, and right is a the bottom.

Repair Clicks
Rappify

The Rappify command applies extreme dynamic filtering
to a selection. As one Peak user described it, “Rappify
can turn your hi-fi into lo-fi!” If the target material has a
pronounced beat, this has the effect of reducing the
material to its most essential rhythmic components. Try
using this function with a variety of different music
material for some surprising and exciting results.

The Repair Clicks command allows you to find and repair
pops or clicks in an audio document. The Repair Clicks
dialog automates the process of finding and removing
clicks (usually indicated by a sharp “spike” in a
waveform), much like a search and replace dialog in a
word processor.

The Repair Clicks dialog

Chapter 11: Peak Menus

267

The Repair Clicks operation works by looking for
discontinuity from sample to sample. For example, a
sample value of -100 followed by a sample value of 10,000
is likely to be a click. Once the area of the click is
identified, a smoothing technique is used to maintain the
original shape of the area being repaired.
If you are working with mostly digitally induced clicks,
the Repair Clicks dialog will become an indispensable
tool. Extremely damaged signals such as those of a
scratching and popping vinyl record will require more
careful repair in addition to using the Repair Clicks
dialog, such as Change Gain, Delete, and the Pencil Tool.
Clicks such as those of a scratching and popping vinyl
record loose their detectability once they are sampled
using Analog to Digital converters.

Using BIAS SoundSoap or SoundSoap Pro will
provide ideal click & crackle reduction for
repairing audio recorded from vinyl. For more
information, please visit the SoundSoap and
SoundSoap Pro web pages,using the links in Peak’s
Links menu.

Repair Size

The Repair Size setting affects how many samples around
the click are used in determining the new shape of the
repair. Repair size can vary from 5 to 100 samples, with
a repair size of 50 samples working well in most
circumstances. Peak will then interpolate what the
correct waveform should be, and repair the click.
Buttons along the bottom of the Repair Clicks dialog
allow you to control repairing, auditioning, and undoing
click repairs:
•

Click the Repair button when you wish to repair a
click found by the Next Click button.

•

Use the Next Click button to search for the next
potential click in the audio selection.

•

Once a click is located, you may listen to the click
using the Audition button. The Audition button
plays the click using the Pre-roll and Post-roll
settings from the Auditioning dialog under the
Preference menu.

•

If you repair a click and are unsatisfied with the
results, simply click on the Undo button.

•

If you would like to repair all of the clicks in the
audio document’s selection without having to
repair each one individually, click the Repair All
button.

Smoothing Factor

Smoothing Factor determines how much smoothing is
applied to the click. Material with high frequency
information may require lower smoothing factors to
preserve the high frequencies. In general, a setting of 4060 percent will repair most clicks.
Detection Setting

The Detection Setting value determines how the clicks
are located. Higher values locate only the most severe
clicks, while lower values will detect less severe clicks.
Note that lower values such as 10% also have a greater
chance of misjudging audio for a click. In general, a
setting of 40-80% works well.

268

You may need to lower the detection setting in the
Repair Clicks dialog to find some clicks, depending upon
their severity. Be careful not to lower the detection
setting dramatically – lower it gradually for the best
results.

Remove DC Offset

Strip Silence

This function allows you to remove any DC Offset in your
audio file. Peak scans the audio for DC offset and then
removes it. Peak will scan the left and right channels of
a stereo file independently. DC Offset is usually caused
by problems in the analog to digital conversion process.
The result is that the waveform is not centered on the
base line-it is offset either higher or lower than the
center line.

Peak includes a Strip Silence tool, which allows areas of
silence, or very low amplitude, to be automatically
silenced, minimized, or completely removed from an
audio document. This tool is useful for removing silence
from recordings that predominantly contain silence (or
very low level audio content), interspersed with some
desired audio content.

LE

Remove DC Offset is not available in Peak LE.

The Strip Silence dialog

Reverse Boomerang

The Reverse Boomerang command mixes a reversed
copy of the selected audio with the original. This creates
a variety of interesting and useful results. Try using
Boomerang on drum loops, voice, and sound effects.

By adjusting the various Strip Silence parameters, you
can control what content is preserved, and what is
silenced completely or deleted from an audio document.
The Strip Silence tool is composed of two sections, the
Noise Gate and the Stripper. Additional information
about Strip Silence is available in Chapter 7: DSP.

The Threshold command allows you to split up an audio
document into its component parts by analyzing the
amplitude levels in the audio document and setting a
cutoff or threshold amplitude. For instance, you might
use the Threshold command on an audio document that
contains successive notes from a musical instrument to
split them up, or on a drum loop to break it up into its
component parts. You can save the segments with
Markers, or as Regions. See Chapter 7: DSP for more info

Vbox SE

Peak includes BIAS Vbox SE for managing and mixing
plug-ins. Think of Vbox SE as a virtual effects box, in
which you can combine, repatch, and mix your plug-ins
in real-time. Using its unique effects matrix, Vbox SE lets
you combine multiple individual plug-ins. Vbox SE can
patch plug-ins in series, in parallel, or in series and
parallel, and you can hot-swap plug-ins. Vbox SE has
controls for each plug-in to mute, solo, and edit
parameters. Vbox SE also provides input and output gain
controls both globally and for each individual plug-in,
and a control for the global Wet/Dry mix. Use Vbox SE’s
A/B comparison feature to get just the right settings, and
use Vbox SE’s presets to store configurations and
settings for later use.

Sampler Support is not available in Peak LE
To use multiple plug-ins within Vbox SE, you must
select Vbox SE from an available insert. While
Vbox SE can be used on one insert, and other VST
plug-ins can be used on other inserts, it is
recommended to use multiple plug-in within the
Vbox SE matrix, as it offers much more control
and flexibility.

Plug-Ins Menu
The Plug-Ins menu provides access to any Audio Units,
BIAS, or VST effects or virtual instrument plug-ins
installed in your system.

Inserts (1-5)

Peak can access plug-ins in two different ways – using
“Inserts” or through Vbox SE. An insert can contain a
single plug-in, and up to 5 inserts are available. When
using inserts, signal flows through the plug-in in each
insert in the order of the insert number. For example, if
an equalizer plug-in is used on Insert 1, and a reverb
plug-in is used on Insert 2, the output of the equalizer
plug-in will flow into the input of the reverb plug-in.
Inserts are typically more convenient when using a small
number of plug-ins is required.

Any installed VST or Audio Units plug-in may be assigned
to any insert. Each insert can contain a single plug-in.
VST & Audio Units plug-ins may be mixed and matched.
When more than one plug-in/insert is active, the output
of Insert 1 flows into the input of Insert 2, the output of
Insert 2 flows into the input of Insert 3, and so on.

LE

Peak LE supports only a single Insert, and can host
only one plug-in at a time.

Bounce

Options Menu

Once you have the right settings for your plug-ins, you
will probably want to apply the effects to the audio
document. This process is called “bouncing.” Bounce
the audio file to process the audio document with any
active plug-ins. Bouncing changes the audio data stored
on disk, allowing you to use the Save command to
permanently apply the plug-in effects to your audio
document (this action is undo-able before saving).

This menu contains a number of commands that allow
you to customize aspects of your Peak software such as
waveform display colors, output volume, and other user
preferences.

Time Units

The Time Units command allows you to choose a time
format for the audio timeline in Peak’s audio document
window. You can choose Samples, Min:Sec:ms, SMPTE
frames, and Bars|Beats. The format you choose will depend
on the nature of the project that you are working on.
Sample Units

The Sample Units command allows you to select whether
sample units will be displayed in decimal, percentage, or dB.
Use Loop in Playback

If an audio document contains a loop (defined by loop
markers), the Use Loop in Playback command (-L)
allows you to listen just to the Loop. If playback is
initiated before the Loop, once the Loop is reached, it
will begin repeating. A check mark next to this menu
item indicates that it is enabled. To turn off loop

Show Marker Times

The Show Marker Times command will show a time value
as well as a marker name for all Peak markers, loops, and
Regions.

Scroll During Play

When the Scroll During Play command is enabled, Peak
will “scroll” through the audio document as playback
progresses. This conveniently allows you to visually
follow the progress of audio playback. A check next to
this menu item indicates that it is enabled. To disable
this command, deselect it.
Move Waveform During Playback

The Move Waveform During Play command will move
the waveform under the cursor as playback progresses,
so that the insertion point is always in the middle of the
waveform display. A check next to this menu item
indicates that it is enabled.
Compute File Max dB

The Compute File Max dB command scans the audio
document for it’s maximum amplitude, and gives you a
readout of the maximum value and its precise location.
This feature requires extra time, and is best used with
smaller audio documents when needing to monitor
overall volume during editing. Otherwise, keep this
option off and option-click the “Max” text left of the
overview to update the current audio document’s
maximum volume indicator at the left of the overview.
Show Edits

The Show Edits command indicates areas of an audio
document that you have edited by enclosing these areas
with hatched lines. This provides you with a convenient
visual reference to portions of the document that have
been affected by your editing actions. Once you save a
document, the edits are saved, and these indicators will
no longer appear.

Show Overview

The Show Overview command (-,) provides an
Overview display of the entire audio waveform along the
top of the Audio Document window under the title bar.
This provides you with a convenient visual reference of
the overall document when you are editing only a
portion in the audio document window.
Show Cursor Info

The Show Cursor Info command (-Shift-T) brings up a
floating, translucent cursor information window, which
follows along with the mouse cursor as it is moved.
Choosing this command again turns the window off.
Auto-Import Dual Mono

Certain audio applications such as Digidesign’s Pro Tools do
not directly support stereo interleaved documents, and
instead use “dual mono” documents which comprise the
right and left channels of stereo material. Enabling the AutoImport Dual Mono command tells Peak to automatically
convert such documents into new stereo audio documents
when you attempt to open these documents with the Open
command. Because Peak actually writes a new stereo audio
file to disk, this conversion process requires hard disk space
equivalent to the two original mono documents.

Please note that the Import Dual Mono command
requires that both files be mono files, have the
same sample rate and bit depth, and the must
have the exact same name followed by the suffixes
“.L” and “.R”. If you are using file type extensions
(.aif, .wav, etc) the format must be
“Filename.Side.Extension”. For example –
“Song1.L.aif ” and ”Song1.R.aif ”.

Auto-Adjust Bounce for Latency

Plug-ins may introduce a short delay, known as latency,
into the audio they are being used to process.
Depending on the type of processing the plug-in
performs, the amount of latency can vary – so it is
common for different plug-ins to produce varying
amounts of latency. Latency typically appears in audio
documents after bouncing, by a shift in samples later in
time relative to the document’s own timeline.
The Audio Info dialog

Peak features an automatic plug-in latency compensation
feature called Auto Adjust Bounce for Latency – which
automatically compensates for the latency introduced
into a processed signal. Automatic latency compensation
may be toggled on and off from Peak’s Options menu. A
check next to the Auto Adjust Bounce for Latency item
indicates that this feature is active. The absence of a
check next to this item means it is inactive.
Plug-in latency compensation may also be used manually.
To compensate for plug-in latency when bouncing effects
on a selection, hold down the Option key when choosing
Bounce, and enter the delay compensation you want in
samples in the Bounce Effects dialog. More information
about Plug-In latency is available in Chapter 8: Plug-Ins.
Audio Info

The Audio Info command (-I) allows you to change an
audio document’s length, sample rate, root key, low key,
or high key parameters. When you choose this
command, a dialog indicating the total time of the
sample, its sample rate, and its key mapping information
will appear. The Audio Info dialog allows you to change
the sample rate, duration, root key (for use in a sample
playback instrument), and high and low key range. Note
that by changing the sample rate, the pitch and duration
of the sample will be affected. (To change the sample
rate of an audio document without changing the pitch,
use the Convert Sample Rate command from the DSP
menu.)

274

You can also adjust the key range (for use in a sample
playback instrument) of a document by clicking on the
miniature keyboard in this dialog. To set the lower limit
of the key range, click on the keyboard at the desired key.
To set the upper limit of the key range, hold down the
Shift key and click on the keyboard. To set the root key
of the audio document’s key range, hold down the
Option key and click on the keyboard. You can also enter
the desired numerical value in any of the appropriate
fields to accomplish this.
Dynamic Scrub Time

Peak provides a unique audio auditioning technique
called dynamic scrubbing. This feature is very useful for
precisely pinpointing a desired location in an audio
document. Dynamic scrubbing allows you to drag the
mouse forward or backward over a waveform while Peak
plays a short loop (between 10 and 600 milliseconds) at
the scrub location. You can control the tempo and
direction (forward or backward) of playback by dragging
the mouse slower or faster, forwards or backwards.
When you have found the location you are looking for,
you can commence editing or playback. The Dynamic
Scrub Time command allows you to choose the length of
this playback loop. Depending on the audio document’s
content, a value of between 40 to 80 milliseconds
typically works well. See Chapter 5: Editing, for step-bystep instructions on how to use the Dynamic Scrubbing
feature.

Why am I getting clicks and pops with my USB device?

1. Update to the most recent Mac OS. There were
major improvements in CoreAudio in OS 10.2.3
and we recommend using the latest OS update.
2. If your USB audio device manufacturer provides
drivers make sure you are using the most recent
version.

6. Open the Hardware Settings dialog. Make sure
you have the USB device selected as your input
AND output device. Also try experimenting with
recording at different CoreAudio buffer sizes
(increasing this buffer size normally helps). The
hardware settings dialog is located in
Audio>Hardware Settings. (See Fig. F)

3. Delete the “ACA Preference” preference file. This
file is located in:
MacintoshHD/Users//
Library/Preferences
After you delete this file, you will need to reset
your hardware and recording settings in Audio
MIDI Setup and in your audio applications.
4. Open the Audio MIDI Setup utility (this is available
in Mac OS X v.10.2 or later, and is shown in Fig. E).
Audio MIDI Setup is found at this location:

won’t be deleted. You can either manually drag
them into the Trash, or launch and then quit Peak.

8. Go to System Preferences>Energy Saver. Make
sure you turn off any energy saving preferences,
especially the option to spin down the hard drive.
Peak will not launch:

•

Does your Macintosh have enough RAM to run
Peak? You must have at least 256MB of RAM—
512MB of RAM is recommended. To find out how
much memory your Macintosh has, choose About
This Macintosh in the Finder’s Apple Menu. A
window will appear telling you how much memory
is currently installed in your computer. If you
have less than the amount required to run Peak,
you will have to install additional RAM in your
computer.

I know that I can process separate channels in Peak, but
not edit them separately. Is there a workaround?

•

Peak stops or stutters during recording or playback:

•

Is your hard disk too slow? For direct-from-disk
recording and playback, your hard drive must have
an average seek time of 18ms or faster. If you are
not sure of the speed of your drive, check with the
manufacturer or the dealer where you purchased
the drive.

•

Is the data on your hard disk fragmented? If the
files on your hard drive have become fragmented
(see Chapter 3 for an explanation of
fragmentation) you may have to use a hard disk
maintenance program such as Norton Speed
Disk™ or the optimizer module of TechTool Pro™
to defragment your drive.

•

Is Peak’s playback buffer in the Playback
Preferences (found in Peak’s Preference menu) set
too low? Try increasing the playback buffer to
128K or higher.

•

Try turning off Interrupt-based metering in Peak’s
Meters dialog.

•

Is AppleTalk turned on? If so, use the Apple menu’s
Chooser to turn it off if you don’t need it.

•

Try increasing the playback buffer size in Peak’s

Peak used to work but now acts strangely or won’t
launch:

•

If Peak used to work but now won’t launch or
suddenly started acting strangely, the Peak
Preferences file may be corrupted. Try quitting
Peak, dragging the Peak Preferences file from the
Preferences folder (in your home directory’s Library
folder) to the Trash icon on the Desktop, choosing
Empty Trash from the Finder menu and then
relaunching Peak.

When I place the cursor on the waveform, it jumps to the
right or the left. Why?

•

This is the result of Peak’s “Auto Snap To
Zero”preference, that automatically places the
cursor at a zero crossing in the waveform. You can
turn it off by going to the Options menu and unchecking the option.

I notice files on my hard drive with Peak file icons, called
“AFM.temp”

•

292

These are temporary files that Peak created as you
edited audio. If you change Scratch Disk

The workaround is to export dual mono files, open
the Left and Right channels in Peak as two separate
mono files, edit them, save them, and then Import
as Dual Mono. You will then have a stereo file with
your changes in it.

sampler. Once the devices have powered up, turn
on the Macintosh. If this does not help, try turning
on your other SCSI devices, then the Macintosh,
and finally the sampler.
When I try to move a region marker that’s in the same
position as a marker, the marker moves instead:

Make sure you have selected “Tape Style” from the
Dynamic Scrub Time submenu, under the Options
menu.

•

When editing markers that exist in the same
space/sample, markers take priority. To get to a
region marker, move or delete the marker first.

There are items in the DSP menu that are grayed out:

•

•

You need to open an audio document before the
DSP effects will be available.
Not all DSP processes are available in Peak LE.

Problems using Peak with a SMDI sampler (via SCSI):

•

Use high-quality, tested SCSI cables that are as
short as possible.

•

Check for SCSI ID conflicts. Make sure every SCSI
device in the SCSI chain has a unique ID.

I try to save files in MP3 format, but the MP3 option is
grayed out:

•

Peak needs to have the LameLib encoder installed.

To install this encoder:

•

Make sure Peak is not running.

•

Download the LameLib.bundle from:
http://homepage.mac.com/awk/lame/

•

Check for problems with SCSI termination. For
more information, consult the manuals of your
SCSI devices. SCSI termination should exist on
each end of the SCSI chain: one termination inside
the Macintosh (usually this is the case), and one
termination on the last SCSI device in the chain.

•

Try turning off Asynchronous transfers in Peak’s
Samplers Preferences dialog.

•

Reduce the number of components in your SCSI
chain. If you have more than one device
connected between the sampler and your
Macintosh, try removing devices to determine if
this affects the errors.

•

Change the power-up order of your devices. Try
turning all SCSI devices on first, including the

•

Select the Peak 4 application and choose Get Info
from the Finder’s File Menu.

•

Open the Plug-Ins tab.

•

Click the Add button.

•

Locate the LameLib.bundle file, highlight it, and
click the Choose button.

•

The next time Peak is launched, MP3 will be an
available option.

I try to instantiate a plug-in on an insert, but there is
already a plug-in called Vbox SE running on that insert:

•

Choosing the Vbox menu item automatically
opens Vbox SE on the first available insert –
perhaps this menu item was chosen and
automatically assigned Vbox SE to the insert you
are trying to use. To turn off Vbox SE, simply

Appendix 3: Troubleshooting

select the insert it is running on, and then choose
None from the submenu.
How to I create a Scratch Disk?

1. Create a folder called "Peak Scratch Disk" on a
drive/volume you prefer. We recommend
partitioning your hard drive or using an external
drive for the scratch disk, however creating a
scratch disk on the same drive as your operating
system will work as well.

Burning to CD-RW media:

Peak supports burning to CD-RW media, however the
CD-RW media must be blank. Peak will not erase a CDRW that already contains data.
To erase CD-RW media:

•

Use the Mac OS X Disk Utility to erase a CD-RW
before attempting to burn audio data to it. The Disk
Utility is located in the Utilities folder, within the
Applications folder.

2. Open Peak’s Preferences dialog.
3. Click on "Scratch Disk".
4. Be sure that only the "Primary” radio button and
"Use" checkbox are selected for the drive you
created your scratch disk folder on as mentioned
in step 1. No other drive should should have
"Primary" or "Use" selected if you are using
multiple hard drives or partitions.
5. Click the "Folder" checkbox, then navigate to the
scratch disk folder you created in step 1. "Choose"
that folder.
6. Click "OK" to exit the scratch disks dialog.
7. Locate the "Audio" menu (located next to the DSP
menu) within Peak.
8. Click on "Record Settings".
9. From the “Record Disk” pop-up menu, choose the
hard drive on which you created the scratch disk,
and click “OK”.
After setting up the scratch disk and record disk
settings be advised that you will have to save all
your recorded files on the scratch disk drive.
Saving on any other drive or volume will result in
the following error "You must save the new audio
recording to the volume that you recorded onto".

Appendix 4:
Recording & Playback
with Mac OS X Audio
HAL & FireWire DV

Introduction
The setup directions in this appendix should be used
only if your audio hardware interface does not include a
dedicated Core Audio driver, and is not supported
natively by the Mac OS. If you are unsure about this,
please contact the hardware manufacturer for details.
Devices that are typically not supported via Core Audio
may include older audio interfaces designed for use in
Mac OS 9.x and earlier, as well as FireWire devices such
as DV camcorders.
While such devices will not allow recording and playback
via Mac OS X’s advanced Core Audio system, they may
still be able to be used for recording and playback via the
Mac OS X Audio HAL system. The Mac OS X Audio HAL
system is essentially the same as the Sound Manager
audio system used in Mac OS 9.x and earlier.

DV. Mac OS X Audio HAL may be used for controlling
third-party audio hardware devices, as well as for
controlling the Mac’s built-in audio hardware. For
example, on a Macintosh that does not feature a built-in
microphone, you might want to use a third-party USB
microphone that is not supported via Core Audio. In
this case, you would have to use Mac OS X Audio HAL.

Audio menu>Sound Out

However, if you planned to use the built-in mic, you
would need to select Mac OS X Audio HAL (System), as
you would be using a component of the Mac’s built-in
audio system.

When to Use Mac OS X Audio HAL, Mac
OS X Audio HAL (System), or FireWire DV
The Audio Menu>Sound Out options include Mac OS X
Audio HAL, Mac OS X Audio HAL (System), and FireWire

In the example above, you should really be using
Core Audio with the Mac’s built-in microphone.

Appendix 4: Recording & Playback with Mac OS X Audio HAL & FireWire DV

295

A4

FireWire DV would be used when you wish to use a
FireWire DV device, such as a DV camcorder for
recording or playback. For example, you might
not have a built-in microphone on your Macintosh
– you can use the microphone on the DV
camcorder as an input source.

5. Also in the Sound dialog, click the Source Tab, and
choose which input you wish to record through.
The configuration options are basically the same
when using Mac OS X Audio HAL, Mac OS X Audio
HAL (System), or FireWire DV. The only differences
will be the inputs that are available in the Source
tab of the Sound dialog, which will vary
depending on the type of device being used as an
input.

Configuring Peak for Recording &
Playback via Mac OS X Audio HAL, Mac
OS X Audio HAL (System), & FireWire DV
Configuring Peak to record & play back via these
alternative audio engines is simple. The steps below will
show you how to do it, but remember, it is
recommended to use Core Audio whenever possible for
optimal performance and quality.

6. In the right side of the Sound dialog, click the
Speaker pop-up menu, and choose whether you
wish to have the Macintosh’s speaker On, Off, or
Off during Recording.

If you are recording through a microphone, it is
probably best to choose Off, or Off during
Recording to avoid feedback.

To Configure Peak to Record & Play Back Audio via Mac OS
X Audio HAL, Mac OS X Audio HAL (System), & FireWire DV:

1. From the Audio menu, choose Sound Out>Mac
OS X Audio HAL (Mac OS X Audio HAL System or
FireWire DV – see previous section for differences
between these options).
2. From the Audio menu, choose Record Settings.

Sound dialog should register about 2/3 of the way up as
a good starting point. If the resulting recordings are at
too low of a level, increase this setting, or increase the
output level on the source being fed into the Macintosh.
If the resulting recordings are “clipped” (distorted), then
lower this setting, or decrease the level of the source being

dialog.
Record Disk

You have now configured Peak for recording and
playback. Be sure that the audio source you plan to
record is connected to the audio interface’s inputs, and
that its outputs are connected to a set of speakers or
headphones.

Record Settings
When you select Record Settings from the Audio menu
(Option-R) or Toolbar, the Record Settings dialog
appears. This dialog is used to configure your settings for
recording with Peak. The Record Settings dialog is
basically the same for Mac OS X Audio HAL, Mac OS X
Audio HAL (System) FireWire DV.

Please note that the settings you choose here
override any previously set with in Sound
Preferences.

The Record Disk pop-up menu allows you to choose
which hard drive you would like to record to. If you
have more than one hard drive connected to your
Macintosh, use this pop-up to select your record
drive. (This option will default to the largest drive
currently available to your Macintosh unless you
select otherwise.) Peak requires that you save the
audio file to the same drive on which it was
recorded.
File Format

The File Format pop-up menu allows you to select the
file format for the incoming audio. You can choose
from AIFF or Sound Designer II. If you need the
newly recorded audio file to be in a different format,
you can always use the Save As function to save it as a
another format once recording is complete. If you do
not select a file format for recording, Peak will default
to AIFF.
Auto Gain Control checkbox

The Auto Gain Control checkbox allows you to
disable the Automatic Gain Control feature used by
the Mac OS X Audio HAL system with some
Macintosh microphone inputs. If the recording
device you are using supports this feature, check the
Auto Gain Control checkbox.
The Record Settings dialog

Monitor checkbox

You will notice several pop-up menus, buttons, and
checkboxes in the Record Settings dialog. These allow
you to select which hard drive to record to, what file

The Monitor checkbox allows you to monitor the audio
throughput while you are recording.

Split Stereo Files checkbox

Device and Sample Format

The Split Stereo Files checkbox allows you to record the
incoming stereo audio as dual mono files rather than a
single stereo file. Dual mono files are used in programs
like Pro Tools, or BIAS Deck, so this option is useful if
you need to record dual mono files (i.e., split stereo).

Clicking on the Device and Sample Format button opens
the Sound dialog. The Sound dialog contains three tabs
– Compression, Sample, Source – with various options.
The right side of the Sound dialog contains the Speaker
pop-up menu, Volume and Gain control sliders, and an
audio input level meter.

Append to document checkbox

The Append to document checkbox allows you to record
into an existing audio document. To record new audio
into an existing document, place the insertion point in
the existing audio document at the point where you
want to insert the new audio. If the insertion point is at
the beginning of the file, the newly recorded audio will
be inserted at the beginning of the file. If the insertion
point is at the end of the file, the newly recorded audio
will be appended to the end of the existing file. If the
insertion point is somewhere in the middle of the file,
the newly recorded audio will be inserted at that point.
If you make a selection of audio, the Append to
document feature will allow you to replace the current
audio with newly recorded audio from the beginning of
the selection through the end of the document or
wherever you stop the recording.
Record timer checkbox

The Record timer checkbox allows you to designate a
specific duration for recording. Peak will stop recording
after this set time and then open the Save dialog for your
audio recording. Checking the Record timer checkbox
will bring up the Recording Time dialog. In the
Recording Time dialog, designate the duration for
recording in seconds and click OK.
Open after saving checkbox

Compression

Peak does not support recording to a compressed
format, so the Compressor pop-up menu should be left
set to None. To apply compression, make your
recording, and once all editing and processing has taken
place, apply compression via the Save dialog. This
approach will yield the best sounding audio.

The Sound dialog: Compression

The Open after saving checkbox determines whether
the audio document is opened in Peak after it is
recorded.

298

The Speaker pop-up at the right of the Sound
dialog can be set to Speaker On, Speaker Off, or
On While Recording. Selecting Speaker On will
allow you to monitor audio to adjust the input
levels prior to as well as during recording, while
On While Recording will only allow you to
monitor levels while you are actually recording.
As you might expect, Speaker Off will mute the
outputs completely.

Sample

Selecting Sample from the Sound dialog pop-up menu
allows you to choose the sample rate and bit depth, as

Peak 5 User’s Guide

well as whether the incoming audio will be recorded as
a Stereo or Mono file. To some degree, the choices that
appear here will depend on your audio hardware. For
more information on bit-depths and sample rates, see
the Glossary.

Hardware Settings

Clicking the Hardware Settings button in the Record
Settings dialog brings up a dialog appropriate to the
audio hardware that you are using with your Macintosh.
Note that in many instances there may be no settings for
a given device (including the Apple Built-In Sound).
Some audio hardware drivers have control panels or
utility applications that will launch when you click on the
Hardware Options button.

bit resolution (bit rate or bit depth)
Describes how many bits-as in “0s” and “1s”-are available
to describe a digital recording. In practice, the bit resolution defines the dynamic range of a sound, whereas
the sample rate defines the frequency range. 24-bit is a
high-resolution bit depth used for professional audio
recording, editing, and processing; 16-bit audio is the
professional Compact Disc standard; 8-bit audio is suitable for less demanding applications, such as multimedia
presentations. More bits result in better quality, but also
require more hard drive storage space. Also refer to
dynamic range, frequency, and sample rate.

blending
Blending is an automatic crossfade function that Peak
applies to areas during cutting, pasting and other editing
processes in order to smooth abrupt transitions between
waveform amplitudes. Blending can be toggled on or off
by choosing the Blending command from the Preference
dialog, or by clicking the Bending enable/disable button
in the Cursor Palette.

clipping
A type of audio distortion that occurs when a source signal (such as from an audio CD player) is recorded at
such a high level that the recording device (such as a
Macintosh running Peak) runs out of “headroom.” It can
also occur when a signal is played back from a audio
source into an audio destination at an excessive level,
such as when a mixing console feeds a signal to a power
amplifier at an extremely high level. In either case, clipping represents a mismatch in level between an audio
source and an audio destination. When digital clipping
302

occurs, such as during digital recording, the results can
be a harsh “crackling” or “raspy” sound. When you use
Peak, you can avoid digital clipping by ensuring that the
record levels are set so that the loudest incoming audio
passages stay below the maximum input level, as indicated on the record or playback meters. Peak’s Clip indicator will easily show any clipping that occurs. Also refer to
headroom.

dB (decibel)
This is the most common unit used for measuring the
level of audio. The greater the number of decibels, the
higher the audio signal. Within Peak, the record and
playback meters show a signal’s relative level in terms of
dB. There are many different kinds of decibel scales, but
for the purposes of using Peak, “dB” can be used to
describe the relative gain of different passages of audio,
or to describe the available headroom during recording.
Also refer to gain and headroom.

DSP
DSP stands for digital signal processing. In the world of
audio, DSP refers to manipulating a digital audio signal
by processes such as level changes, reverberation, delay,
or other such effects. Peak uses DSP to perform many of
its audio processing tasks-including those found in the
DSP menu or Toolbar.

dynamic range
In audio recording terminology, dynamic range refers to
the range in level between the quietest and loudest passages of a selection of audio. It is usually expressed in

Peak 5 User’s Guide

decibels. Bit resolution determines a recording’s dynamic range. An 8-bit recording has 256 available levels,
which translates into a dynamic range of 48 dB. This may
be suitable for some applications, but it may also sound
noisy, since the difference in gain between the loudest
passages and the quietest passages (which may contain
hiss and other potential noise) is not that great. A 16-bit
recording has 65,536 available levels, which translates
into a high-quality dynamic range of 96 dB. As a rule of
thumb, you can calculate dynamic range in decibels by
multiplying the bit rate by “6.” Also refer to bit resolution, decibel, and gain.

fade-in/fade-out
A fade-in is a process where the gain of an audio signal is
increased from zero (silence) to its full volume. A fadeout is a process where the gain of an audio signal is
decreased from its full volume to zero (silence). Peak
allows you to create fade-ins/fade-outs by making a selection and choosing the Fade In or Fade Out command
from the DSP menu, or from the Toolbar. Envelope
shapes can be editing with the Fade In Envelope or Fade
Out Envelope commands in the Preference dialog.

frequency
Sound consists of waves, which occur in cycles.
Frequency refers to how frequently these wave cycles
occur in a given period of time (generally, one second).
The higher the frequency of a sound, the higher its
“pitch” as perceived by human ears. Frequency is measured in Hertz (Hz), or cycles per second. Roughly speaking, humans are able to hear sounds in the frequency
range between 20 Hz and 20,000 Hz (20 kHz).

gain
1) The process of amplifying a signal. 2) A way to express
relative signal levels for audio. For instance, by adding 6
decibels of level to a signal, we double the perceived
loudness of the signal. Also refer to decibel and headroom.

headroom
Describes how much gain is left before a signal induces
clipping or distortion. When recording with Peak, the
record meters indicate how much headroom is left
before clipping. When playing back audio in Peak, the
meter strip at the bottom of the screen will indicate this
as well. Most professional audio engineers leave between
3 dB and 12 dB of headroom while recording, to minimize the possibility of clipping. If you leave too much
headroom, however, your signal may be recorded at too
low a level, and you may end up with excessive noise or
hiss. Also refer to clipping, decibel, and gain.

Hz (Hertz)
This is the unit of measurement for frequency, and refers
to the number how many “cycles per second” a sound
wave generates. In the world of sound, the higher the
number of Hertz, the higher the frequency of a sound
and hence the higher its “pitch” as perceived by human
ears. A thousand Hertz can be expressed as 1 kHz (one
kilohertz), so that 20,000 Hertz may also be referred to
as 20 kHz.

loop

MP3

Loops are used to sustain or repeat a section of audio.
They can be used for material that you intend to transfer
to a sampler, or simply for playback within Peak itself.
Peak allows you to create one loop per audio file. You
can do this either by making a selection and choosing
the Loop this Selection command (-L) from the
Actions menu or Toolbar, or by placing markers at the
desired start and end point of a region, and defining the
markers as loop markers.

marker
A marker is a location in an audio document that you define as
important; you can also think of a marker as a “memory location.”
By marking a specific location in a recording, you can easily navigate to it for selection, editing or playback purposes. Peak allows
you to define a marker by pressing -M or clicking a Toolbar button, either when playback is stopped or while it is engaged.

QuickTime

sampler

This is an audio format developed by Apple Computer
for QuickTime-based multimedia. It is supported by all
Macintosh software applications that support
QuickTime. The QuickTime format is best if you plan to
use an audio document in multimedia applications that
support QuickTime, such as Adobe Premiere or
Macromedia Director.

A sampler is an electronic instrument capable of digitally recording or “sampling” a sound and playing it back
from a keyboard or other controller. Samplers are used
extensively in all areas of audio production, ranging from
recording and performance, to film production and
sound design. See sample rate.

sample rate
region
A region is a portion of an audio document bounded by
region markers. Regions are portions of an audio document defined using the New Region command (-ShiftR) from the Actions menu or Toolbar. Regions can be
saved into only AIFF and Sound Designer II files created
by Peak. See also playlist .

sample
(verb) Sampling refers to the act of recording audio
material digitally by a sampling instrument or other digital recording device. See sampler and sample rate.

Sample rate describes how frequently an analog audio
signal is been “sampled” or analyzed as it is recorded and
converted to a digital medium. Sample rate directly
affects audio fidelity in terms of upper frequency
response: the higher the sample rate, the higher the
available frequency response. A fundamental principle of
sampling states that to accurately capture a sound, the
sample rate must be at least twice the highest frequency
in the sound. The standard sample rate for Compact
Discs is 44.1 kHz. The following are common sample
rates which are supported by many Macintosh computers and Peak software.

192.000 kHz
sample
(noun) A sample refers to audio material which has
recorded digitally or “sampled” by a sampling instrument or other digital recording device. Sample also
refers to a single wave-cycle” snapshot” of sound. See
also sampler and sample rate.

This is the standard for HD (High-Definition) audio
hardware/production. This rate results in an upper frequency response of 96 kHz-well above the range of
human hearing.

96.000 kHz
This is the standard sample rate for Digital Video Disc
(DVD) audio, and is often used by sound editors work-

Glossary

305

G

ing in audio post-production for DVD. This rate results in
an upper frequency response of 48 kHz-well above the
range of human hearing.

Also refer to bit resolution, frequency, and Hertz.

SCSI
48.000 kHz
This is one of two standard sample rates for digital audio
tape (DAT) recorders, and is often used by sound editors
working in audio post-production for video or film. This
rate results in an upper frequency response of 24 kHzabove most people’s hearing range.

Stands for Small Computer System Interface. It is a standard developed to allow a variety of computers and
peripheral devices such as hard disks, CD recorders,
scanners, and other storage media, to connect and transfer data. Most external hard drives designed for use with
the Macintosh are SCSI hard drives and must be connected to the SCSI port on the rear of the Macintosh.
The SCSI specification allows up to seven SCSI-equipped
devices to be connected or “daisy-chained” together.

44.100 kHz
This is the standard sample rate for Compact Discs, digital audio tape (DAT) recorders, and high-fidelity audio
applications on Macintosh and PC-compatible computers with 16-bit playback capability. It is colloquially called
“forty-four one” (as in 44.1 kHz). Most sound engineers
working in music production - or anything that may be
distributed on a CD-work at this rate. This rate results in
an upper frequency response of 22,000 Hz-above most
people’s hearing range.

SMDI
SMDI stands for SCSI Musical Data Interchange Protocol.
SMDI Samplers use SCSI to send samples between
devices several times more quickly than over MIDI. In
order to transfer samples between the Macintosh and
your sampler using SMDI, you must connect a SCSI cable
between your Macintosh and the sampler.

Sound Designer II
22.050 kHz & 11.025 kHz
These sample rates are sometimes used for lower-fidelity audio playback on Macintosh and PC-compatible computers. Many games, web-sites and other multimedia
productions utilize 22.050 kHz (or lower) 8-bit audio,
since it uses half the disc space of CD-quality audio. The
22.050 kHz sample rate results in an upper frequency
response of 12.025 kHz; this may sound “muffled,” since
most people can hear considerably higher frequencies
than 12.025 kHz.
306

This is an audio file format developed by Digidesign for
use with its digital audio products. The format can also
be read by a wide variety of Macintosh-based audio editing and multimedia development programs, including
Peak.

VST
“Virtual Studio Technology” - VST is a real-time, native

Peak 5 User’s Guide

plug-in standard created by Steinberg Media
Technologies, AG. Plug-ins conforming to the VST standard can be used in any compatible host application.
VST plug-ins are accessed from a central directory in the
Mac OS, making it very easy to maintain large collections
of plug-ins. Peak supports “Mach-O” and “carbonized”
VST 1.0 format effects plug-ins.

WAVE
This is Microsoft’s Windows Audio File Format. It is supported by many Windows software applications and
some Macintosh applications. The WAVE format is best if
you plan to use an audio document in an application that
supports or requires WAVE format files.

zero-crossing
The zero-crossing is the point where the waveform
meets the zero crossing line or the center line through
the waveform. It is the point of zero amplitude in the
waveform.
