Optimizing for
Sound Forge
Software

This chapter contains information on configuring your system to optimize the performance of Sound Forge®
software.

Defragmenting your hard drive
The Sound Forge application is a disk-based digital audio editor that allows editing operations to be
performed on the system’s hard drive rather than in memory. Because of this, you are able to edit large files as
well as retain extensive undo/redo information and clipboard data.This also means that the hard drive
specified for temporary storage must have sufficient free space to store large quantities of data.
With time and usage, hard drives become fragmented, leading to discontiguous files and slow access. This is
particularly true for older hard drives. Since the software is hard drive intensive, faster disk access equates
better performance. Therefore, the initial step in improving system performance is hard drive
defragmentation. The computer’s operating system is typically equipped with a defragmenting program that
should be run prior to using Sound Forge software.

Increasing total buffer size
The total buffer size value determines the amount of RAM used for recording to/playing from the hard drive.
A total buffer size of 512 KB is recommended, but increased buffering may be necessary if you detect gaps
during playback.
Increasing the total buffer size requires additional memory. Combined with a large preload size, this may
result in a delay when starting and stopping playback.
1. From the Options menu, choose Preferences. The Preferences dialog is displayed.
2. Click the Audio tab.
3. Use the Playback buffering slider to configure an appropriate buffer size value and click OK.

Turning off the playback cursor and record counter
The playback cursor and record counter options determine whether these displays are updated during
recording and playback. If you detect dropouts and skipping at high sample rates (greater than 44,100 Hz),
turn these displays off to minimize processing overhead.
1. From the Options menus, choose Preferences. The Preferences dialog is displayed.
2. Click the General tab.
3. Clear the Show the position of the playback cursor and Show the record counter while recording check boxes and

click OK.

Turning off the play (output) meters
Sound Forge play meters use a small amount of processing overhead during playback. However, if you detect
dropouts during playback and previous fixes have failed, try turning off these meters.
From the View menu, choose Play Meters. The check mark adjacent to the command is cleared, indicating
that the play meters are turned off.

Turning on passive updating for time and video displays
Passive update options lower the priority of redrawing the time and video displays during playback. When
these options are turned on, the displays update only if there is ample time. Frequently this goes unnoticed,
and enabling these options minimizes playback overhead with little or no inconvenience.

Time displays
This feature is available only in the full version of Sound Forge software.
From the Options menu, choose Time Display, and choose Passive Update from the submenu. A check mark
appears next to the command to indicate that this option is turned on.

Video displays
From the Options menu, choose Video, and choose Passive Update from the submenu. A check mark appears
next to the command to indicate that this option is turned on.

Synchronizing audio and video
If your video has been opened from a slow device, such as a CD-ROM or network drive, Sound Forge
software may have trouble accurately playing back the audio and video in sync. You should always copy your
video files to a fast hard drive. Listed below are a few tips that can help when trying to synchronize the audio
and video:
• After assembling or editing the audio you wish to use with your video, place markers during video
playback to correspond to any major synchronization points. You can locate a particular frame by dragging
the cursor along the audio if the Video Preview window is open or the Animate Video Strip option is
enabled. After primary locations have been identified, drag your audio to these markers to mix, paste, and
crossfade audio.
• Features such as Insert Silence, Delete/Clear, and Time Stretch are commonly used to correct
synchronization. Another useful trick is to create a region representing the offset between a video frame
and audio event. Then you can enable Lock Loop/Region Length and drag the offset region to a preceding
silent section. Use the region as a template for adjusting the audio stream length—either copying and
pasting to insert time or deleting to remove time.

Mouse Term

Description

Pointing
Clicking

Moving the mouse pointer over an item.
Pointing to an item and quickly pressing and releasing the left mouse button. If there is no left or right specification,
left-clicking is implied.
Pointing to an item and quickly pressing and releasing the right mouse button. Right-clicking is frequently used to
display shortcut menus.
Identical to clicking, but instead of pressing and releasing the mouse button once, it is done twice in quick succession.
Double-clicking always indicates the left mouse button.
Identical to clicking, but instead of pressing and releasing the mouse button once, it is done three times in quick
succession. Triple-clicking always indicates the left mouse button.
Clicking the right mouse button while holding down the left mouse button. This is used to toggle options and is a
shortcut for drag-and-drop editing and using the Magnify tool.
Holding down the Shift key while clicking the mouse. Shift-clicking is typically used to skip dialogs and quickly repeat
operations.
Holding down the Ctrl key while clicking the mouse. Ctrl-clicking is used to modify the operation of a normal click.
Holding down the left mouse button while moving the mouse pointer and releasing the mouse at the desired location.
Dragging is used to quickly move sections of data between windows, as well as to adjust sliders, scrollbars, and faders.
Holding down the right and left mouse buttons while adjusting sliders and faders increases the resolution of the
movement. This is useful when making fractional adjustments to parameters.

Meters
Meters display audio levels in a number of different places in Sound Forge software: the Play Meters show
audio file levels; meters in the Record dialog help you adjust levels for recording; and meters in the Wave
Hammer® dialog help you adjust levels when applying this effect. Regardless of where the meters appear,
you can control them in much the same way.
The full version of Sound Forge software provides peak and VU/PPM (peak program) meters that you can use to
monitor your audio levels.
• The peak meters display instantaneous levels during playback to help you determine the loudest level in
your audio signal and whether the signal is clipping.
• Volume unit (VU) and peak program (PPM) meters help you determine the perceived loudness of your
audio signal (peak program meters provide faster response times to volume increases than VU meters).
VU/PPM meters are especially helpful when you’re mastering: comparing two audio files’ VU/PPM
readings will help take the guesswork out of matching levels.
VU/PPM readings should fall near the 0 (or reference) mark. 0 VU is merely a reference level, and your
signal may exceed 0 VU. To prevent clipping, keep an eye on your peak meters. Peak levels should never
exceed 0 dB. To accommodate louder or softer intensity material, you can use the Status tab in the
Preferences dialog to calibrate the VU/PPM meters to their associated levels on the peak meters and adjust
the VU meters’ sensitivity (to access the Preferences dialog, choose Preferences from the Options menu).

Resetting clipping indicators
When audio levels are too high, clipping can occur. A red indicator appears at the top of the meter to show
when audio is clipping. Click to reset the indicator, or right-click the meters and choose Reset Clip from the
shortcut menu.

Scaling meters
Meters can display a peak range and a VU (volume unit)/PPM (peak program)
scale. To change the meter’s display levels, right-click the meter and do one of the
following actions:
• Choose Peak Range from the shortcut menu, followed by the desired range from
the submenu.
• Choose VU/PPM Scale from the shortcut menu, followed by the desired scale
from the submenu.
VU and PPM scales are most useful for displaying the average volume of the signal:
the meter represents the RMS average level during playback, and their attack and
decay are not as sensitive as the peak meter.
PPM scales are useful for monitoring peak levels. The meters use a fixed
integration time (5 or 10 ms) that is sensitive to increases in volume, but the
meters are less sensitive to decreases in volume than the VU scales, which
produces less meter activity and decreased eyestrain.

Displaying VU/PPM meters
Sound Forge peak and VU/PPM (peak program) meters allow you to monitor your audio levels.
You can toggle the display of the meter’s VU/PPM scale on and off. Right-click the meter and choose Show
from the shortcut menu.

VU/PPM

Adjusting the VU meters’ sensitivity

This feature is available only in the full version of Sound Forge software.
Unlike peak meters — which read instantaneous changes in your audio signal — the VU/PPM meters read a
portion of the signal and calculate the average level. The size of the signal that the meters read is determined
by the meters’ integration time.
To set the amount of data surrounding the cursor that will be used to calculate levels in the VU meters,
specify a value in the VU meter integration time box on the Status tab of the Preferences dialog (to access the
Preferences dialog, choose Preferences from the Options menu).
The PPM scales use a fixed integration time:

Stereo files
When a data window displays a stereo file, the upper half of the data window shows the left channel and the
lower half shows the right channel.

Working with stereo files
When playing, editing, or processing stereo files, you can select the left channel, the right channel, or both
channels. However, certain processing tasks cannot be performed on an individual channel of a stereo file.
For more information, see Single-channel editing on page 47.

Selecting data in stereo files
When editing a stereo file, the waveform display is
divided into three sections. The mouse pointer
location determines which channel (or channels) is
selected.
• The upper quarter of the data window selects
the left channel (shown in yellow).
• The lower quarter of the data window selects

Single-channel editing

Stereo files are held together by the nature of their stereo format. Because of this, you cannot perform certain
editing operations (such as cut or paste) on a single channel of a stereo file.
Channel lengths must remain equal in stereo files. Frequently, this issue can be side-stepped by copying a
single channel of a stereo file to the clipboard. Once this mono selection is located on the clipboard, you can
perform any of the following action:
•
•
•
•

Paste it into a mono file.
Paste it into both channels of a stereo file.
Mix it into a single channel of a stereo file.
Mix it into both channels of a stereo file.
Note: When mixing mono clipboard data to a stereo file, the
Mono to Stereo dialog prompts you to mix it to the right, left,

CHAPTER

Getting Started

4
The Sound Forge® digital audio editing tool is for users from all musical backgrounds. It is an extremely deep
program, containing features that may only be required by the most advanced or specialized users.
Nonetheless, a firm grasp of Sound Forge basics is essential. This chapter is designed to provide you with
information on Sound Forge fundamentals.

Creating a project
This feature is available only in the full version of Sound Forge software.
You can use Sound Forge project files to organize and work with your media files nondestructively. When
you save a project file, two things are created: a .frg file and a subfolder that contains your media file and all
of the temporary files created while working on your project. This file is not a multimedia file, but is used to
render the final file after editing is finished. When you copy, cut, paste, and otherwise edit your project, the
process is nondestructive—meaning you can edit without worrying about corrupting your source files.
Within the project file, you can also undo any past operations, including those occurring before your last
save. Once you are finished working with a project file, you can save your work to a media file using the
Render As option on the File menu.
Note: To use the advanced undo/redo capabilities mentioned
above, you must have the Allow Undo past Save check box
selected on the General tab of the Preferences dialog. To
access the Preferences dialog, choose Preferences from the
Options menu.
1. From the File menu, choose Save As to save the current data window to a project file. The Save As dialog

is displayed.
2. Using the Save in drop-down list, locate the folder where you want to save the project.
3. From the Save as type drop-down list, choose Sound Forge Project File (*.frg).
4. In the File name box, enter a name for the file.
5. Click the Save button. A .frg file is created with the name you specified, and a folder with a similar name

(projectname_frg, for example) is created in the same location for the temporary files.
Important: The associated project folder created by this

process should not be deleted, as this will cause your project
file to be unusable.

Peak files
When you first open a file, the entire file is scanned and a peak file is created. The peak file is stored with the
same name and in the same location as the audio file, but it is given an .sfk extension. This peak file is
automatically updated whenever the original file is edited.
If you modify a file in another application, you can regenerate the peak file by choosing Rebuild Peak Data
from the Special menu.

Working with video files
The Sound Forge application has the ability to open and save many video file formats. The video files
cannot be edited within the software, but this functionality allows you to attach, detach, and edit audio for
the video. Once you’ve edited the audio, you can preview the audio and video together.

The maximum and minimum sample values and the locations (in samples) where they
occur.
These values may help determine if clipping will occur in the audio file. These values can
also be used to determine the noise level of a signal for use with Noise Gate (a built-in
XFX plug-in installed with the Sound Forge full version). For example, to determine the
noise amplitude of a file, run Statistics on a region of noisy silence.
The Root Mean Square of the sample values relative to the RMS value of a maximumamplitude square wave (the loudest possible recording).
On short intervals, this value relates to the volume level of the audio file. If used on a
large selection with large volume variation, this value becomes less meaningful.
The sum of all sample values in the selected region divided by the number of samples. If
this value is not zero, it usually indicates a DC offset in the recording process.
The number of times per second that the waveform fluctuates from a negative to a
positive value.
This value can be used as a rough estimate of the frequency of the audio data for very
simple waveforms.

Saving files as a workspace
This feature is available only in the full version of Sound Forge software.
To accommodate complex editing scenarios, you can save the entire workspace as an alternative to saving
individual files. Workspaces are saved as Sound Forge Workspace (SFW) files. When you open a workspace
file, all files are restored to their previous sizes, positions, and magnification. In addition, each file’s current
cursor position, custom views, and plug-ins in the Plug-In Chainer are restored. For more information, see
Creating and using views on page 94 and Using the Plug-In Chainer on page 190.
Saving the current workspace
1. From the File menu, choose Workspace, and choose Save As from the submenu. The Save Workspace

dialog is displayed.
2. Browse to the folder where the file will be saved.
3. Enter a name for the file in the File name box and click Save.
Opening a workspace
1. From the File menu, choose Workspace, and choose Open from the submenu. The Open Workspace dialog

Working with projects
Projects are new to Sound Forge software; however, if you’ve used ACID or Vegas software, then you’ll be
quite familiar with how to use Sound Forge projects. You should note that Sound Forge projects do function
slightly different than ACID and Vegas projects.
A project file is not a multimedia file. It contains pointers to the original source files, so you can edit your
project nondestructively without changing your source files. When you edit a Sound Forge project, you can
undo edit operations even past your last save. For more information, see Using undo and redo on page 71.

Saving the project
This feature is available only in the full version of Sound Forge software.
1. Click anywhere in the data window to select it.
2. From the File menu, choose Save As to display the Save as dialog.
3. Select the folder where you want to save the file from one of the following locations:

• From the Save in drop-down list, choose a drive and foler.
• From the Recent drop-down list, choose a folder where you have previously saved files.
4. In the File name box, enter a name for the file or select a file in the browse window to replace the exisitng

file.
5. From the Save as type drop-down list, choose Sound Forge Project File (*.frg). Sound Forge software creates a

.frg file in the folder you specified and creates a subfolder to store your sound and temporary files.
Note: Since a Sound Forge project contains all your original
sound data plus all PCM temporary files, they can take some
time to create.

Warning: Deleting a project’s [filename]_frg folder will

break the project.

Saving the project path in the rendered file
This feature is available only in the full version of Sound Forge software.
1. Save your Sound Forge project. The project must be saved before you can embed the project reference in

the rendered file.
2. Follow the steps in Using the Save As/Render As dialog on page 59 to choose the file type and location for

rendering your files and then select the Save project as path reference in rendered media check box.
Note: This check box will be unavailable if you did not save
your project or if you are rendering using a third-party fileformat plug-in.
3. Click Yes if you would like to open the file in a new window or click No if you would like to close the

dialog and return to the Sound Forge window.
Note: If you modify the project file after rendering, the

project data will no longer match the rendered file. To edit a
project using a path reference, the project file and all media
must be available on your computer.

Editing a media file’s source project
When your Sound Forge project uses source media files that are rendered with an embedded project path
reference, you can easily open the source project in the associated application if you need to edit the media.
By saving your project path reference when you render files in ACID 5.0, Sound Forge 8.0, or Vegas 6.0, you
can quickly access the media from Sound Forge via the Edit Source Project shortcut menu.
Note: The project information in the rendered file is only a
reference to a project file. If you modify the source project file
after rendering, the project data will no longer match the
rendered file. To edit a project using a path reference, the
project file and all media must be available on your computer.
1. Right-click one of the following items:

• the waveform in a data window
• a media file in the Explorer window
2. From the shortcut menu, choose Edit Source Project. An ACID, Vegas, or Sound Forge window will open

with the source project.
If you are editing a source project using a computer other than the computer where the project was
created, then the editing computer must meet the following requirements:
• The software that was used to create the project must be installed and the project file extension (.acd,
.acd-zip, .veg, or .frg) must be registered on the editing computer.
• The editing computer must have the same version (or later) of the software as the computer where the
project was created.
• The project file must exist on the editing computer using the same file path as on the computer where
the project was created.
• The project’s source media must exist on the editing computer. If the media files do not use the same file
path as on the computer where the project was created, you will be prompted to choose a new folder or
replacement files.
3. Edit the project as necessary.
4. Render the edited project using the same name as the original media file and close the editing application.
Note: If you are editing an existing track, your project will

automatically be updated with the latest rendered media file.

Clearing the Undo/Redo History for the current file

Clearing the current file’s Undo/Redo History frees up disk space by deleting the file’s temporary undo/redo
files. However, deleting these temporary files prevents you from undoing changes made to the file since it
was last saved (or beyond, if you have the Allow Undo past Save check box enabled on the General tab of the
Preferences dialog). To clear the undo/redo history for the current file, go to the Special menu, choose Undo/
Redo History, and choose Clear from the submenu.
Note: A file’s undo/redo history is also automatically cleared

when you close the file or exit the software.
Clearing the Undo/Redo History for all open files

You can simultaneously clear the undo/redo history for all open files. Once again, however, you cannot undo
any previous changes once these histories are deleted. To clear the undo/redo history for all open files, go to
the Special menu, choose Undo/Redo History, and choose Clear All from the submenu.

data samples must be represented by each horizontal point when audio data displays in the data window.
Depending upon the editing operation, you may want to view the entire file at once or a small portion of
data in greater detail. For this reason, you can utilize two varieties of zooming: time ruler zooming and level
ruler zooming.

Understanding the zoom ratio

The zoom ratio determines the number of samples represented by each horizontal point on the screen. The
zoom ratio is a value of X:Y, where X is the number of horizontal points and Y is the number of samples. If
the ratio is 1:1, each point on the screen represents one sample. At this zoom ratio, a brief but detailed
selection of time is displayed.

Waveform at 1:1 zoom ratio

Conversely, if the zoom ratio is 1:1024, 1,024 samples are represented by each point on the screen and a
greater length of time is displayed.
For very precise editing, you may want to zoom in more tightly than a 1:1 ratio. The Sound Forge full version
software allows up to a 24:1 ratio, where 24 points on the screen represent one sample. This high level of
zoom may be useful when editing with the Pencil tool. For more information, see Repairing audio glitches
manually with the Pencil tool on page 157.

Waveform at 24:1 zoom ratio

Changing the zoom ratio

To edit the zoom ratio, use the Zoom In/Out spin control located adjacent to the zoom ratio display.
• Clicking the plus/minus buttons increases/decreases the zoom ratio by single-step increments.
• Dragging the spin control increments the zoom ratio quickly in the corresponding direction.
Right-clicking the waveform display allows you to quickly access time ruler zoom commands from
the shortcut menu.

Changing the sample rate
The sample rate is the number of samples per second, measured in hertz (Hz), used to record audio.
• When creating a new file in the Sound Forge full version software, you can specify sample rates from
2,000 Hz to 192,000 Hz.
• When creating a new file in Sound Forge Audio Studio software, you can specify sample rates from
2,000 Hz to 48,000 Hz.
Typical sample rates are stored as presets in the Sample rate drop-down list. In addition, you can increase or
decrease the sample rate of an existing audio file.
1. Open and play the Voiceover.pca file.
Note: This file is located in the same folder as the

application.
2. Right-click the Sample Rate status box and choose 48,000 from the shortcut menu.
3. Play the file. Notice that the pitch is higher and the duration is slightly shorter.
4. Right-click the Sample Rate status box and choose 8,000 from the shortcut menu.
5. Play the file. Notice that the pitch is lower and the duration is longer.

Changing the sample rate of a file also changes the pitch and duration. To change the sample rate of a file
while preserving its duration and pitch, use the Resample command. For more information, see Resample on
page 184.

Changing the bit depth
Bit depth refers to the number of bits used to represent a sound. You can increase or decrease a file’s bit
depth.

Increasing bit depth
Increasing the bit depth does not improve the quality of a
file, but it allows subsequent processing to be performed
with increased precision.
Note: The maximum bit-depth allowed for a sound file in

Sound Forge Audio Studio software is 16 bit.
1. Open a file with a small bit depth.
2. From the Process menu, choose Bit-Depth Converter. The

Bit-Depth Converter dialog is displayed.
3. From the Bit depth drop-down list, choose a larger value

and click OK.
Note: When increasing a file’s bit depth, the Dither and
Noise shaping

controls should be set to None and Off,

respectively.

CHANGING FILE ATTRIBUTES AND FORMATS

CHP. 6

Decreasing bit depth
To maximize storage space, larger sound files (24- and 16-bit) are frequently converted to smaller (16- and 8bit) files. However, representing a sound file at a decreased bit depth results in audible distortion referred to
as quantization error.
Note: The maximum bit-depth allowed for a sound file in

Sound Forge Audio Studio software is 16 bit.
1. Open a 16-bit file.
2. From the Process menu, choose Bit-Depth Converter. The Bit-Depth Converter dialog is displayed.
3. From the Bit depth drop-down list, choose 8 bit.
4. If desired, choose an option from the Dither drop-down list. For more information, see Dither on page 97.
5. If desired, choose a Noise shaping type. For more information, see Noise shaping on page 98.
6. Click OK.
Note: There are no rules regarding maintaining audio

quality when decreasing bit depth. Experiment with the Dither
and Noise shaping controls to determine the optimum settings
for each audio file.

Understanding dither and noise shaping
You can adjust Dither and Noise shaping settings when decreasing a file’s bit depth.
Dither

The Dither value determines the randomness of the dither (generated noise) used to mask quantization
distortion resulting from conversion to a lower bit depth. This drop-down list requires you to select from
several shapes, each of which roughly describes the pattern that would be produced if you plotted a graph
with the dither amplitude on the X-axis and the probability of the dither values on the Y-axis.
As is frequently the case when working with audio, you should experiment with dither values to yield the
best results. However, keep the following information in mind:
Setting

Description

Half Rectangular

Eliminates distortion resulting from conversion to a lower bit depth, but the noise level is more likely to be
dependent on the signal. This setting uses a maximum dither noise amplitude of 0.5 LSB (least
sugnificant bit).
Identical to Half Rectangular, but with a maximum dither noise amplitude of 1 LSB (least significant bit).
Eliminates distortion products as well as any noise floor modulation, but results in a slightly higher noise
level. The option typically works well in conjunction with noise shaping. For more information, see Noise
shaping on page 98.
Behaves like triangular dither, but shifts its noise into higher frequencies. This is typically the best option
when used in conjunction with noise shaping. For more information, see Noise shaping on page 98.
Does not perform as well as Rectangular and Triangular dither, but may be suitable for certain audio.

Noise shaping

The Noise shaping value determines the aural positioning of quantization noise. Using this control, you can
shift the noise into audio registers that are less perceptible to human hearing. This lowers the perceived noise
floor and creates the illusion of cleaner audio.
• High-pass contour noise shaping attempts to push all quantization noise and error into high frequencies.
• Equal-loudness contour noise shaping attempts to push the noise under an equal-loudness type of curve.
Noise shaping dangers

Noise shaping places quantization noise near the audio’s Nyquist frequency, a value equal to one-half of the
file’s sample rate. Consider the following information:
• A file with a sample rate of 44.1 kHz has a Nyquist frequency of 22.05 kHz (at the high end of human
hearing). Applying noise shaping to this file results in audio perceived to be cleaner than it actually is.
• A file with a sample rate of 22 kHz has a Nyquist frequency of 11 kHz (well within the sensitive range of
human hearing). Applying noise shaping to this file results in audio that is perceived to be noisier than it
actually is. Ironically, this defeats the entire purpose of noise shaping.
For this reason, we do not recommend using noise shaping on files with sample rates less than 44.1 kHz.

Minimizing quantization error
There are at least three methods of minimizing quantization error when decreasing a file’s bit depth: noise
gating, compression, and normalization.
Noise gating

Frequently, low-level signals become noise when a file’s bit depth is decreased. For this reason, it is preferable
to have complete silence between sounds in an audio file.
1. From the Effects menu, choose Noise Gate. The Noise Gate dialog is displayed.

Specify a noise gate

2. Choose a noise gate preset from the Preset drop-down list and click OK. A noise gate is applied to the

audio, negating its low-level signals.
Compressing

Decreasing the dynamic range of a sound file makes it easier to represent with decreased bit depth.
1. Open the Graphic Dynamics dialog:
a. For users of the Sound Forge Pro software: from the Effects menu, choose Dynamics, and choose Graphic

from the submenu. The Graphic Dynamics dialog is displayed.
b. For users of Sound Forge Audio Studio software: from the Effects menu, choose Dynamics. The

Using Markers,
Regions, and the
Playlist/Cutlist

This chapter describes the use of markers, command markers, the Regions List, and the playlist/cutlist. These
tools allow you to tag and organize audio data and make audio editing more efficient. The Sound Forge®
application can save marker, Regions List, and playlist/cutlist information as metadata in most file types. You
also have the option of saving the Regions List and playlist/cutlist to an external file. For more information,
see Using the Save As/Render As dialog on page 59.

Why use markers, regions, and the playlist?
There are at least four reasons for you to master the use of these features:
•
•
•
•

Rapid navigation
Added effects for streaming media
Multiple versions of edits
MIDI synchronization and triggering

Rapid navigation
The most obvious use of the Regions List is for dissecting an audio file into multiple regions. Once created,
regions can be selected and played in the data window. You are also able to tag important time positions with
markers. This allows you to navigate large files and locate important audio events.

Added effects for streaming media
Command markers allow you to add interactivity to media streamed over the Internet by inserting metadata
into streaming media files. As your file plays, any number of other actions can be triggered, including
opening a Web page in a browser or displaying caption text.

Multiple versions of edits
This feature is available only in the full version of Sound Forge software.
The playlist and cutlist allow you to try out different edits before committing to them. You can add regions
to the playlist or cutlist and then rearrange and audition them endlessly without requiring the software to
perform an edit on the file.
Another advantage is that you can quickly save regions organized in the playlist or cutlist as a new file based
on the finished arrangement.

MIDI synchronization and triggering
This feature is available only in the full version of Sound Forge software.
You can trigger regions created in Sound Forge software using MIDI or SMPTE timecode. This feature is
used for synchronizing audio files to sequencers, MIDI controllers, or any other time-based media. For
example, a MIDI trigger can be assigned to an audio file in the software and triggered by a sequencer along
with other MIDI instruments. For more information, see Triggering region playback on page 236.
You can also assign SMPTE times to special effect audio files. This allows you to match audio to the action
on the screen.

Using markers
A marker is a tag placed in an audio file that is used as a reference point. Markers make navigating a file
easier and more efficient.

Inserting markers
1. Click to position the cursor in the waveform.

Detecting and marking clipping
This feature is available only in the full version of Sound Forge software.
The clip indicators in the play meters help you determine whether clipping occurs in your file, and you can
use the Find command to find audio that matches levels you specify. For more control, however, you can use
the detect clipping tool.
From the Tools menu, choose Detect Clipping to scan a selection of audio for clipping and add markers where
clipping occurs.
Markers can be quickly selected from the list in the Go To dialog. Also, markers are displayed in the Regions
List for quick playback.
1. Select the audio you want to scan.
2. From the Tools menu, choose Detect Clipping. The Detect Clipping dialog is displayed.
3. Choose a setting from the Preset drop-down list or adjust the controls as necessary.
a. Drag the Threshold slider to determine the sound level you want to find.
b. Set a value in the Clip Length box to specify how many sequential samples must meet the Threshold

setting to constitute clipping.
4. Click the OK button.

The selection is scanned and a marker is added whenever there are a number of sequential samples
(determined by the Clip Length setting) with the same value above the Threshold setting.
Tip: Use Detect all clip-related plateaus from the Preset drop-

down list to detect clipped peaks that may exist in your file
after decreasing the levels in the file. You can then use the
Pencil tool or the Clipped Peak Restoration tool in the Sony
Media Software Noise Reduction plug-in to restore the
clipped peaks.

Using markers to create regions
Once you have placed markers in a waveform, you can use them to create regions. For more information, see

Using command markers in streaming media files
Command markers add interactivity to media streamed over the Internet by inserting metadata into
streaming media files. As your file plays, any number of other actions can be programmed to occur. These
commands are a part of the Windows Media Audio, Windows Media Video, and RealMedia streaming
formats. Most frequently, these actions add text or open a related Web site.
Command markers can also indicate when an instruction (function) occurs in a WAV file being used in a
radio broadcast environment (Scott Studios data). The following two sections define the markers for both
streaming media and Scott Studios files.
Note: While streaming, media files can be played on any
hard drive or CD-ROM. They require a special streaming
media server (provided by your ISP) to stream properly
across the Internet.

Important: Windows Media Player 9 will ignore metadata

commands unless the Run script commands when present
check box is selected on the Security tab of the player's
Preferences dialog. Be sure to instruct your audience to select
this check box before playing your file.

Recording,
Extracting, and
Burning

This chapter describes the processes for recording audio, extracting audio from a CD, and writing audio to a
CD in Sound Forge® software.

Recording audio
The software has two central methods for recording: manual (normal) and automatic. In normal recording,
you choose your settings and control your recording session while you’re sitting at your PC. With automatic
recording, you can choose your settings and set your trigger parameters for recording automatically—
whether you’re at your PC or not.

Specifying recording and playback options
Basic audio preferences

From the Options menu, choose Preferences and select the Audio tab to specify recording and playback
options. For more information, see Basic audio preferences on page 300.
Advanced audio preferences

The Advanced Audio Configuration dialog allows you to view information about and adjust settings for the
audio device selected in the Audio device type drop-down list on the Audio tab of the Preferences dialog.
To display the dialog, select a device from the Audio device type drop-down list, click Apply, and then click the
Advanced button.

7. Click the Arm button

to have recording begin as soon as possible after you click the Record button

.

Arming the Sound Forge software prior to recording opens the wave device and loads all recording buffers
in order to minimize the amount of time between clicking the Record button and when the recording
starts. This optional step can allow for more accurate takes when recording in Punch-In mode.
8. If desired, select the Prerecord buffer check box and specify the amount of time to buffer prior to recording

when the software is armed for recording. A prerecording buffer helps to ensure you won't miss a perfect
take if you're a bit slow to click the Record button.
When you click the Record button, recording begins and the sound data in the buffer is committed to disk.
For example, if you set a 15-second buffer, recording effectively begins 15 seconds before you click the
Record button.
Note: The prerecord buffer is unavailable in punch-in mode.

This feature is available only in the full version of Sound Forge software.

Recording automatically
In addition to the normal recording method, there are three automatic recording methods: Time, Threshold,
and MIDI Timecode. These recording methods enable you to trigger recording to begin automatically, using
a specified device, with no intervention necessary. You can set up multiple automatic recording sessions to
take place at different times, and set a session’s recurrence level for one time, daily, or weekly. For your
recording sessions to take place, the Sound Forge application must be started and armed for recording.

a buffer when the software is armed for recording. A safety buffer helps to ensure you won’t miss a perfect
take if you set the threshold a bit too high.
When the prerecord buffer is enabled, recording starts when the audio input reaches the threshold level
and commits the sound data in the buffer to disk. For example, if you set a 15-second buffer, recording
effectively begins 15 seconds before the input reaches the set threshold level.

particularly important to record input signals as loud as possible when planning to decrease the bit depth.
This maximizes the dynamic range.
However, the input signal must never exceed the range of values that can be recorded digitally. When the
input signal exceeds the safe digital recording range, the waveform peaks are clipped, resulting in audible
digital distortion.
1. Open the Record dialog.
2. From the Device drop-down list, choose the device to use for recording.
3. Apply the input signal to be recorded. The meters display levels relative to the signal.
4. Slowly increase the level of the input signal until the peak value is the -6 dB range. If the peak reaches

0 dB, the wave is clipped and a Clip indicator appears above each meter.
If clipping occurs, decrease the level of the input signal until the record level is maximized without clipping.
Scaling the record meters

Like the play meters, the record meters can be scaled to various dynamic ranges by right-clicking the meters
and choosing Peak Range or VU/PPM scale from the shortcut menu and then choosing the desired range from
the submenu.
For typical recording situations, the -42 to 0 dB range is the most practical. However, when recording very
low-level audio signals, you should consider the -90 to 0 dB range. Scaling the record meter to this range is
also a good method of gauging the noise level in the system.
Updating the meters

Right-click the meters and choose Aggressive Update from the shortcut menu to increase the priority of
updating the meters. This results in more accurate metering, but increased CPU usage.

You can write audio to CD if your system is configured with a supported CD-R/RW drive and the necessary
drivers. CDs are burned using the track-at-once method, meaning that additional tracks can be added to the
CD over a period of time. Once all desired tracks are added, you must close the CD before it can be played in
a consumer CD player. However, once you have closed a CD, you can no longer add tracks to it.

Correcting the sample rate for CD burning
Sample rates deviating from 44,100 Hz cause CD track lengths to be miscalculated. When attempting to
write a file to CD that deviates from the 44,100 Hz sample rate, you are prompted to change the sample rate.
Selecting Yes automatically resamples audio to 44,100 Hz.
In addition, you can use the Resample tool to change the sample rate of a file prior to burning the CD. For

Editing, Repairing,
and Synthesizing
Audio

This chapter introduces some of the Sound Forge® advanced editing, repair, and synthesis features.

Crossfading, overwriting, and replicating
Earlier in this manual, paste and mix were described as ways of adding clipboard contents to the current data
window. As your audio editing projects become more elaborate, you may discover the need for three more
sophisticated paste operations: crossfade, overwrite, and replicate.

Crossfading
Crossfading is a variation on pasting that joins two selections of audio data that would be awkward or
distracting if pasted together. In crossfading, the destination data decreases in volume (fades out) as the
source data increases in volume (fades in). A crossfade is the audio equivalent of the filmmaker’s dissolve.
1. Open the Voiceover.pca and Musicbed.pca files.
2. Select all data in the Voiceover data window.
3. Copy the selection. The data is placed on the clipboard.
4. Place the cursor at the approximate middle of the Musicbed data window. This is where the crossfade will

begin.
5. From the Edit menu, choose Paste Special, and choose Crossfade from the submenu. The Crossfade dialog

is displayed.
You can also display the Crossfade dialog by right-clicking the data window and choosing
Crossfade or by pressing Ctrl + F .
6. From the Preset drop-down list, choose Normal crossfade and click OK.
7. Play the Musicbed.pca file. Notice that the volume of the musicbed decreases while the voiceover volume

increases.

Overwriting
Overwriting allows you to replace the current selection with the contents of the clipboard and has two basic
guidelines:
If
The selection is longer than the clipboard contents
The clipboard contents are equal to or longer than the
selection

Then
Data is overwritten from the beginning of the selection
for the lenght of the clipboard contents only.
Data is overwritten for the length of the selection only.

Overwriting a selection
1. Open the Voiceover.pca file.
2. Create a selection containing “Wow.”
3. Copy the selection. The data is placed on the clipboard.

Create a second selection

4. Create a selection of approximately the same length containing the final “...and easier.”
5. From the Edit menu, choose Paste Special, and choose Overwrite from the submenu or right-click the data

window and choose Overwrite from the shortcut menu. The selection is overwritten with the clipboard
contents.

Overwrite the selection

Note: If any of the selection data remains, it is because the
length of the clipboard contents was less than the length of the
selection.

Replicating
Replicating allows you to overwrite a selection with several copies of the clipboard contents. When
replicating, you must specify whether you want to use partial copies of the clipboard contents or only
complete copies.
• Using partial copies of the clipboard content completely overwrites the selected area.
• Using complete copies of the clipboard content prevents a portion of the selection from being overwritten
unless the selection length is an exact multiple of the length of the clipboard contents.
Replicating a selection
1. Open the Voiceover.pca file.
2. Create a selection containing “Wow.”
3. Copy the selection. The data is placed on the clipboard.

4. Create a selection containing “Sound editing just gets easier.”

5. From the Edit menu, choose Paste Special and choose Replicate from the submenu. The Replicate dialog is

displayed.
6. Select the Copy partials radio button and click OK. The selection is overwritten with multiple copies of the

clipboard contents. A partial copy of the clipboard contents is used where appropriate.

Repeating an operation
Once you perform an operation on an audio file, you can quickly repeat it with the same parameters by
choosing Repeat from the Edit menu. This allows you to reapply the same effect, process, or function to a
different section of audio using the same parameters.
Note: In the Edit menu, the Repeat command displays in

conjunction with the name of the previous function.
Repeat an operation by doing any of the following actions:
•Hold Shift while choosing the command from its menu.
•Press Ctrl + Y .
•Click the Repeat button
on the Standard toolbar.

Using drag-and-drop
You can take advantage of using drag-and-drop to perform many common tasks. Drag-and-drop operations
make controlling the Sound Forge software faster and more intuitive and allow for increased editing power.
The three major drag-and-drop editing operations are paste, mix, and crossfade.

Dragging mono selections into stereo destinations
When pasting, mixing, or crossfading a mono selection into a stereo file, you can mix the selection to both
channels by dropping it on the destination data window’s center line. Otherwise, the selection is mixed into
the left or right channel exclusively.

Snapping to events in drag-and-drop operations
A major advantage of drag-and-drop editing is the ability to snap to markers, regions, time increments, or
other events in the destination window. All drag-and-drop operations can be configured to snap (or align) to
points in the destination file based on the events established within that file.
The following table describes all events that drag-and-drop selections snap to in the destination file.

Finding and repairing audio glitches
This feature is available only in the full version of Sound Forge software.
Glitches are commonly the result of analog audio editing, analog to digital transfer, or electronic noise.
Sound Forge software provides you with a tool for locating audio glitches and three distinct tools for
repairing them: channel, interpolate, and replace. In addition, you can repair audio glitches manually using
the Pencil tool.

Locating glitches
The Find tool allows you to quickly locate glitches, specific volume levels, or silence in a file. The Find tool’s
glitch algorithm locates glitches by examining the file for instances where the waveform matches the
specified threshold slope and sensitivity criteria. The cursor then moves to the location of the glitch to allow
you to repair it. This tool only locates one glitch at a time. Therefore, it may be necessary to execute this
command several times on a file to locate all glitches.
1. Open any audio file containing glitches.
2. From the Tools menu, choose Find. The Find dialog is displayed.
3. From the Find drop-down list, choose Glitch.
4. Adjust the Threshold slope fader to configure the minimum slope that constitutes a glitch.

• A high value detects only glitches with steep slopes.
• A lower value detects glitches with both steep and more gradual slopes.
5. Adjust the Sensitivity fader to determine the sensitivity of the detection algorithm.

• A high value results in any part of the waveform with a slope greater than the Threshold slope being
detected as a glitch.
• A lower value forces the algorithm to verify that the slope is indeed a glitch, and not simply a portion of
the smooth waveform.
6. Click OK. The first glitch in the file is found and its location is marked with the cursor.
Tip: If you can hear glitches that the Find tool does not
locate, decrease the Threshold slope and increase the
Sensitivity.

Locating additional glitches using the same settings

Once you have configured the settings in the Find dialog, you can find the next glitch in the file without
viewing the Find dialog. To find the next glitch using the current settings, hold Shift while choosing Find
from the Tools menu or hold Shift while clicking the Find button
on the Tools toolbar.
Using the Shift key in this way is not limited to finding glitches. You can hold Shift and choose any
command from a menu to repeat the command with the same settings. For more information, see Repeating an
operation on page 150.

Repairing audio
There are several ways to repair audio glitches.
Copying the other channel

For glitches in a single channel of a stereo file, you can replace the glitched section of damaged channel with
the corresponding data from the “good” channel.
Note: This method only works if both channels contain

similar audio.
1. Open the stereo file containing the glitch.
2. Create a selection in the channel containing the glitch, three or four times longer (maximum 50 ms) than

the glitch itself.

3. From the Tools menu, choose Repair, and choose Copy Other Channel from the submenu. The selected data

is replaced with the corresponding data from the “good” channel. In addition, rapid crossfades are created
at the beginning and end of the replacement selection to prevent a new glitch from being created.
Tip: If this method fails to repair the glitch, undo it and apply
Copy Other Channel

again, this time using a longer selection.

CHP. 9

155

Interpolating new audio

This is the most basic method of repairing glitches. New audio data is simply interpolated based on the data
at the beginning and end of the selection. This method results in a straight line connecting the beginning
and end of the selection. Interpolation should only be used to repair small (less than 2 ms) glitches.
1. Open the file containing the glitch.
2. Right-click the data window and choose Zoom from the shortcut menu, and choose In Full from the

submenu.
• If you are using Sound Forge Pro software, the file displays at a 24:1 zoom ratio.
• If you are using Sound Forge Audio Studio software, the file displays at a 1:1 zoom ratio.
3. Create a selection containing the glitch.
Tip: To improve the accuracy of this feature, the selection

should be as small as possible while still containing the glitch.
4. From the Tools menu, choose Repair, and choose Interpolate from the submenu. The glitch data is replaced

with interpolated data.

Data is interpolated within the selection

Replacing audio with preceding data

The Replace tool allows you to repair audio files by replacing the damaged data with the data immediately
preceding it. This repair method is useful for repairing longer glitches such as needle drops and scratches.
1. Open the file containing the glitch.
2. Create a 5 to 50 ms selection containing the damaged audio.
Note: The maximum allowed replace time is 0.5 seconds.
3. From the Tools menu, choose Repair, and choose Replace from the submenu. The selection is replaced

with the selection of identical length immediately preceding the damaged data. In addition, rapid
crossfades are created at the beginning and end of the replacement selection to prevent a new glitch from
being created.

Repairing audio glitches manually with the Pencil tool

The Pencil tool is for users who prefer to repair their audio glitches manually. This tool allows you to repair
waveform glitches by redrawing the damaged waveform section. However, the Pencil tool can only be used
when a file’s waveform displays at a zoom ratio of 1:32 or lower.
1. Open the file containing the glitch.
2. Zoom in tightly on the glitch.
3. Select the Pencil tool using any of the following methods:

• From the Edit menu, choose Tool, and choose Pencil from the submenu.
• Click the Pencil Tool button
in the Standard toolbar.
• Click the Edit Tool Selector in the top-left corner of the data window until the Pencil tool is displayed.
4. Drag to draw a new waveform section. The new section is integrated into the original waveform, replacing

the section containing the glitch.
Repairing audio using Audio Restoration plug-in

Sound Forge software includes an ExpressFX™ plug-in called Audio Restoration that you can use to remove
surface noise from old recordings. For more information on this plug-in, please see the Sound Forge online
help file (accessible from the Help menu by choosing Contents and Index).

Generating audio with frequency modulation
This feature is available only in the full version of Sound Forge software.
The Sound Forge FM Synthesis feature can be used to create complex sounds from simple waveforms using
frequency modulation (FM).
In frequency modulation, the frequency of a waveform (carrier) is modulated by the output of another
waveform (modulator) to create a new waveform. If the frequency of the modulator is low, the carrier is
detuned slowly over time. If the frequency of the modulator is high, the carrier is modulated so quickly that
numerous additional frequencies (or sidebands) will be created.
Using the FM Synthesis tool, up to four waveforms (operators) can be used in a variety of configurations.
Depending on the configuration, a waveform can be a carrier, a modulator, or a simple, unmodulated
waveform.
Generating a waveform
1. From the Tools menu, choose Synthesis, and choose FM from the submenu. The FM Synthesis dialog is

displayed.

2. Specify the length (in seconds) of the generated waveform in the Total output waveform length box.
3. Use the Configuration slider to configure the arrangement and number of operators used to generate the

waveform. For more information, see Specifying the number and arrangement of operators on page 160.
4. Modify individual operators as needed. For more information, see Modifying an operator on page 160.

is placed in the file.
6. Click OK.

Specifying the number and arrangement of operators

Dragging the Configuration slider changes the graphical representation of the arrangement and number of
operators used to generate the waveform. When configuring your waveform, keep the following guidelines in
mind:
• The outputs of horizontally joined operators are simply mixed. The outputs of the bottom operators are
mixed to form the final output. Mixing unique simple waveforms is referred to as additive synthesis.
• Operators joined vertically are FM carrier-modulator pairs. The bottom operator is the carrier and the top
operator is the modulator.
• Operators without other operators directly above are simple waveform generators.
• When three or more operators are stacked, the top operator modulates the operator below it, which
modulates the following operator, and so on.
Modifying an operator
1. Select the Current radio button corresponding to the operator to be modified.
2. Use the envelope graph to modify the amplitude of the operator over time. For more information, see

Envelope graphs on page 44.
3. From the Operator shape drop-down list, choose a waveform shape.
4. Specify the frequency of the operator in the Frequency box.
Tip: If Frequency is set to 0.00, a DC (zero-frequency)

waveform is produced regardless of the waveform specified.

Note: When you choose Filtered Noise from the Operator
shape drop-down list, Frequency determines the highfrequency content of the noise.

5. Use the Feedback slider to determine the amount of the operator's output that is used to modulate itself. If

the operator is also being modulated by another waveform, the feedback path and the modulator output
are mixed together to modulate the carrier.
6. Use the Amplitude fader to determine the output gain that is applied to the current operator after the

amplitude envelope.
Note: If the operator is a modulator, this control (along with
the envelope) determines the amount of frequency modulation
applied to the carrier. If the amplitude of a modulator is high,
harsh audio may result.

This chapter provides descriptions of processing presets and previews as well as an overview of all functions
in the Sound Forge® Process menu.

Applying presets
Many Sound Forge dialogs contain drop-down lists of presets used to quickly apply processes and effects.
Presets are especially useful when you are learning the application, as they allow you to hear the results of
processing as well as view the control settings used to produce these results.
Note: All information regarding presets in this chapter is
applicable to DirectX® Plug-Ins (effects) from Sony Media
Software.

Using presets
1. Open the Voiceover.pca file.
2. From the Process menu, choose Fade, and choose Graphic from the submenu. The Graphic Fade dialog is

displayed.
3. From the Preset drop-down list, choose the -20 dB exponential fade out preset. Notice that the dialog’s

controls change to reflect the -20 dB exponential fade out.
4. Click the Preview button. The following actions occur:

• The Preview button changes to a Stop button.
• The effect previews on a brief selection of audio.
For more information, see Previewing processed audio on page 165.
5. From the Preset drop-down list, choose the -3 dB exponential fade out preset. Notice that the dialog’s

controls update to reflect the new preset and the effect automatically previews.
6. Select the Bypass check box. The original audio previews with no effects. For more information, see

Bypassing a process while previewing on page 166.
7. Clear the Bypass check box and click OK. The -3 dB exponential fade out preset is applied to the audio file.

Previewing processed audio
You can preview the effect that a process has on a file by using the Preview button. This button is found in
most audio processing dialogs. You can use previews to fine-tune effect parameters without leaving the
dialog. More importantly, using previews reduces wasted processing time.

Setting custom preview parameters
You can customize the preview parameters to satisfy your editing preferences. You can save custom
previewing settings for the current process alone or for all processes.
Customizing previews for the current process
1. Right-click the dialog and choose Configuration from the shortcut menu. The Preview Configuration dialog

is displayed.
2. Edit the preview parameters as desired. For more information, see Preview parameters on page 165.
3. Click OK. The preview parameters are updated and retained until you close the current dialog.
Customizing previews for all processes

This feature is available only in the full version of Sound Forge software.
1. From the Options menu, choose Preferences. The Preferences dialog is displayed.

Allows you to specify an amount of sound to be deleted from the beginning of each file
and specify a maximum length for converted files. If a file is longer than this length, it is
trimmed. This preset is useful for creating sample clips.

Attack threshold

Determines the threshold level for detection of the trim/crop start point: -Inf. indicates complete silence,
and 0 dB indicates maximum amplitude level.
Release threshold

Determines the threshold level for detection of the trim/crop end point: -Inf. indicates complete silence, and
0 dB indicates maximum amplitude level.
Fade in

Determines the length (in milliseconds) of the fade applied to a section of audio prior to the detected trim/
crop start point.
Fade out

Determines the length (in milliseconds) of the fade applied to a section of audio following the detected trim/
crop end point.
Minimum inter-phrase silence

When you choose the Remove silence between phrases function, the Minimum inter-phase silence value
determines the minimum amount of silence needed between phrases for a new region to be created.

Bit-Depth Converter
The Bit-Depth Converter is used to increase/decrease the bit depth of a file while concealing the resulting
quantization noise.
• Decreasing a file’s bit depth decreases the overall size of the file, but results in added quantization noise,
which can be masked using dither and noise shaping.
• Increasing a file’s bit depth—while not improving the quality of the audio—allows subsequent audio
processing to be performed with greater accuracy and resolution.
Prior to decreasing a file’s bit depth, you should optimize the audio for conversion. For more information, see
Minimizing quantization error on page 98.
Note: There are no rules regarding maintaining audio

quality when decreasing bit- depth. For this reason, you
should always experiment with the Dither and Noise shaping
controls to determine the optimum settings for each file.

Converting a file’s bit depth
1. Open the Musicbed.pca file.
2. From the Process menu, choose Bit-Depth Converter.

3. From the Bit depth drop-down list, choose the desired bit depth.
4. If necessary, use the Dither drop-down list to specify the type of dither used to mask the quantization noise

results from lowering a file’s bit depth. For more information, see Dither on page 170.
5. If desired, use the Noise shaping drop-down list to specify any noise shaping to be applied to the file. For

more information, see Noise shaping on page 170.
Note: When increasing a file’s bit depth, set the Dither and
Noise shaping controls

CHP. 10

to None and Off respectively.

Dither

This control allows you to specify the randomness of the dither (generated noise) used to mask quantization
distortion resulting from conversion to a lower bit depth. You can select from several shapes, each roughly
describing the pattern that would be produced if you plotted a graph with the dither amplitude on the X-axis
and the probability of the dither values on the Y-axis.
As is frequently the case when working with audio, experimentation with dither values yields the best
results; however, keep the following information in mind:
Setting

Description

Half Rectangular

Eliminates distortion resulting from conversion to a lower bit depth, but the noise level is more likely to be
dependent on the signal. This setting uses a maximum dither noise amplitude of 0.5 LSB (least
sugnificant bit).
Identical to Half Rectangular, but with a maximum dither noise amplitude of 1 LSB (least significant bit).
Eliminates distortion products as well as any noise floor modulation, but results in a slightly higher noise
level. The option typically works well in conjunction with noise shaping. For more information, see Noise
shaping on page 170.
Behaves like triangular dither, but shifts its noise into higher frequencies. This is typically the best option
when used in conjunction with noise shaping. For more information, see Noise shaping on page 170.
Does not perform as well as Rectangular and Triangular dither, but may be suitable for certain audio.

Rectangular
Triangular

Highpass Triangular
Gaussian

Noise shaping

Determines the aural positioning of quantization noise. Using this control, you can shift the noise into audio
registers that are less perceptible to human hearing. This lowers the perceived noise floor and creates the
illusion of cleaner audio.
• High-pass contour noise shaping attempts to push all quantization noise and error into high frequencies.
• Equal loudness contour noise shaping attempts to push the noise under an equal loudness-type of curve.
Noise shaping dangers

Noise shaping places quantization noise near the audio’s Nyquist frequency, a value equal to one-half of the
file’s sample rate. Consider the following information:
• A file with a sample rate of 44.1 kHz has a Nyquist frequency of 22.05 kHz (at the high end of human
hearing). Applying noise shaping to this file results in audio perceived to be cleaner than it actually is.
• A file with a sample rate of 22 kHz has a Nyquist frequency of 11 kHz (well within the sensitive range of
human hearing). Applying noise shaping to this file results in audio that is perceived to be noisier than it
actually is. Ironically, this defeats the entire purpose of the Noise shape control.
For this reason, we do not recommend using noise shaping on files with sample rates less than 44.1 kHz.

Channel Converter
This feature is available only in the full version of Sound Forge software.
The Channel Converter is used to convert audio files between mono and stereo formats. In addition to this
basic function, the Channel Converter allows independent level settings for each channel and can therefore be
used to intermix the channels of a stereo file to create pan effects.

Using the Channel Converter
1. Open the Voiceover.pca file. Notice that this is a mono file.
2. From the Process menu, choose Channel Converter. The Channel Converter dialog is displayed.

3. From the Preset drop-down list, choose Mono to Stereo-100% if it is not already selected and click OK. The

mono file converts to stereo with equal levels mixed to the left and right channels.

DC Offset
Audio that is not centered around the zero baseline in the waveform display is said to have a DC offset. DC
offsets are typically caused by electrical conflicts between the sound card and input device. The DC Offset
function is used to change the baseline of an audio file by adding a constant value to each sample to
compensate for offsets.

Estimating DC Offset
You can estimate the DC offset of an audio file by choosing Statistics from the Tools menu.

Normalize using Average RMS level (loudness)

This radio button normalizes the audio file using the detected average RMS value of the audio file. This is
helpful for matching the apparent loudness of a number of individual recordings. For more information, see
Scan settings area on page 179.
Normalize to

This fader specifies the level to which the highest peak should be set.
• With Peak level, if the peak level is -10 dB and the Normalize to value is -3 dB, a constant boost of 7 dB is
applied to the entire file.
• With Average RMS level, normalizing to 0 dB means boosting the signal until it has the same apparent
loudness as a 0 dB square wave. This results in all the dynamic range of the signal being flattened and all
peaks being either clipped or seriously compressed. For more information, see If clipping occurs on page 181.
Note: As a rule, normalizing using Peak levels to 0 dB is
acceptable, but normalizing using Average RMS level to
anything above -6 dB is not recommended.

Scan settings area

The controls in this area allow you to determine the response of the RMS level scan to the dynamics in the
file.
Control

Description

Ignore below

Determines the level of audio data included in the RMS calculation. Data below the threshold is
ignored, effectively eliminating silent sections from RMS calculation. The Ignore below fader
should be set a few dB above perceived silence. If Ignore below is set to -Inf., all audio data is
used. However, if the value is set too high (above -10 dB) the RMS value may never rise above
the threshold. In this case, normalization cannot occur. For this reason, you should evaluate the
threshold by clicking the Scan Levels button. For more information, see Scan Levels on page
180.
Determines how quickly the scan responds to transient peaks.
Determines how quickly the scan should stop using transient peak material after it begins to
drop in level. Slower release times result in more data being included in RMS calculation.
Allows the scan to compensate for the Fletcher-Munson Equal Loudness Contours. The
Fletcher-Munson Equal Loudness Contours illustrate that very low- and high-frequency
audio is less perceptible to the human ear than mid-range audio. Therefore, selecting
this option forces the scan to factor this into RMS calculation.

This feature is available only in the full version of Sound Forge software.
When you select the Use current scan level check box, the current scan levels are used without initiating a
new scan. This is useful when applying scan levels from a different selection or file to the current selection,
thereby allowing identical gains to be applied to multiple files. This option can also be used to scan a
selection of an audio file containing the loudest or most constant levels and then apply that scan to
normalize the entire file.

Audio peaks that will result in clipping are limited below 0 dB using non-zero attack and
release times to minimize distortion. This mode is useful for getting loud and clear audio

The selection’s peak amplitude level is normalized to 0 dB, thereby allowing the
maximum possible constant gain without clipping the selection. However, less gain is
applied than would be necessary to achieve the Normalize to RMS level.
Audio is permitted to clip and distort.
Audio peaks that will result in clipping force the normalize function to cease processing
and alert you that clipping will occur at the current level.

Reset Envelope

Clicking the Reset Envelope button clears all but the two original envelope points.
• For the Pan modes, these two points prevent unintended panning.
• For the Stereo expand and Mix Mid-Side modes, these two points prevent unintended expansion.

Resample
The Resample command allows you to change the
sampling rate of a file without altering its pitch or
duration.
• Resampling to a lower sample rate results in less
frequent samples and a decreased file size, but adds
aliasing noise to the audio. For more information, see
Apply an anti-alias filter during resample on page 185.
• Resampling to a higher sample rate results in extra
samples being created through interpolation and an
increased file size. Like increasing bit depth, upsampling does not improve the quality of an audio file,
but permits subsequent audio processing to be
performed with greater precision.

Downsampling audio
1. Open the Musicbed.pca file.
2. Right-click the data window and choose Properties from the shortcut menu. The Properties dialog is

displayed. Notice that this file has 44,100 Hz sample rate and a file size of 0.48 MB.
3. Click OK.
4. From the Process menu, choose Resample. The Resample dialog is displayed.
5. From the Preset drop-down list, choose Resample to 8,000 Hz with anti-alias filter and click OK. The audio is

resampled at 8,000 Hz.
6. From the File menu, choose Save As. Save the resampled file with a new name and close it.
7. Open the resampled file and view its Properties dialog. The sample rate is lower (8,000 Hz) and the file

size is smaller.

5. Open the new file and view its Properties dialog. Notice that the sample rate is higher (48,000 Hz) and

the file size is larger.
6. Play the file. Notice that resampling to a higher sample rate produces an audio quality at 48,000 Hz that is

indistinguishable from the quality at 8,000 Hz.

Resample controls
The following controls are located in the Resample dialog.
New sample rate

Determines the sample rate (in Hz) at which the file is resampled.
Tip: Processing is quicker when downsampling by an even

multiple (such as when going from 44 kHz to 22 kHz).
Interpolation accuracy

The Interpolation accuracy value determines the complexity of the interpolation method used during
resampling. Interpolation accuracy is most apparent in high frequencies, but the audible difference between
the values is subtle and often undetectable without the use of test tones.
• A value of 1 is suitable for general-purpose audio.
• A value of 2 or 3 is good for high-end audio applications.
• A value of 4 results in professional-quality audio, but requires substantial processing.
Apply an anti-alias filter during resample

Selecting this check box applies an anti-aliasing filter during the resampling process. Remember that the
maximum frequency that can be represented by a sample rate is one-half of the sampling rate (the Nyquist
frequency). Therefore, high frequencies cannot be accurately represented when downsampling. The antialiasing filter prevents high frequencies from becoming low-frequency distortion.
Tip: It is also advisable to apply an anti-aliasing low-pass

filter to an audio file prior to resampling to a lower sample
rate.
Set the sample rate only (do not resample)

If the Set the sample rate only check box is selected, the playback rate is changed without resampling the data.
This means that the pitch of the original file is not preserved. For this reason, this option is only useful for
quickly converting between two similar sample rates.

Adjusting effect parameters with envelopes
An envelope is displayed in the data window for each effect parameter that you've chosen to automate.
Envelope points represent plug-in parameter settings at a specific point in time.
You can add points, adjust their positions, and change the fade curves between points to modify effect
parameters and the transitions between them.
Note: When you automate an effect’s frequency parameter

— such as the modulation frequency parameter in the
amplitude modulation effect — you may notice that the
frequency changes are more apparent when moving through
the lower frequencies. This is because frequency scales plugins use a logarithmic scale, but effect automation uses linear
interpolation.To make the automated frequency changes
sound more natural, change the fade curve types to change
the interpolation rates between envelope points. For high-tolow frequency sweeps, use a fast fade curve; for low-to-high
frequency sweeps, use a slow curve.

CHAPTER

Using Acoustic Mirror

12

and Wave Hammer

This chapter is designed to familiarize you with the Sound Forge® Acoustic Mirror™ and Wave Hammer™
effects. The Acoustic Mirror effect is a powerful digital signal processing tool that allows you to add
environmental coloration to your existing recordings. The Wave Hammer effect is an audio mastering tool
that features a classic compressor and volume maximizer.
Acoustic Mirror and Wave Hammer effects are available only in the full version of Sound Forge software.

What are the Acoustic Mirror effects?
The Acoustic Mirror effects represents an advance in reverb technology in that it incorporates the acoustical
responses of a given environment or venue into your audio files. You may never play Carnegie Hall, but that
does not mean that your recordings can’t sound like it. Taking this concept even further, this effect allows
you to simulate the signal response of vintage musical equipment. Imagine the money you’ll save not having
to buy those paired U-47s.

The acoustic signature
Acoustic Mirror effects use the environment’s acoustic signature, or impulse response. These acoustic
signatures are saved as impulse files and given the extension .wav or .sfi. An extensive library of high-quality
impulse files are included. In addition, you can collect your own acoustic signatures and create custom
impulse files.

Adding an acoustic signature to an audio file
1. Open and play the Saxriff.pca file.
Note: This file is located in the same folder as the

application.
2. From the Effects menu, choose Acoustic Mirror. The Acoustic Mirror dialog is displayed.
Note: You must have an active file in the Sound Forge

workspace to start the Acoustic Mirror tool.

3. Click the Browse button located next to the Impulse field and locate the Acoustic Mirror Impulse Files folder

on the Sound Forge CD.
4. Double-click the folder. Several impulse subfolders display.
5. Double-click the Large venues folder. Several impulse files display.
6. Double-click Stadium, Camp Randall 50 yrd line.sfi. This impulse file’s acoustic signature is added to the

Saxriff.pca file and you are returned to the Acoustic Mirror dialog.
7. Click Preview. The processed file plays and the sax riff is virtually placed in a football stadium-sized venue.
8. Select or clear the Bypass check box to toggle between the processed and unprocessed audio.

Adjusting the acoustic signature
Once you add an acoustic signature to a file, you can use the controls of the Acoustic Mirror dialog to
precisely configure the reverb effect. More importantly, you can preview configuration changes as quickly as
you make them.
1. Open a file and display the Acoustic Mirror dialog.
2. Verify that the Real-time check box is selected.
3. From the Impulse drop-down list, choose the desired impulse file and click Preview. The processed audio

file plays. Notice that all dialog controls are set to their default values.
4. Drag the Dry Out fader up. Notice the audible change in output as the balance between the Wet Out and
Dry Out

values changes.

Tip: If you are experiencing difficulty previewing processing

in real-time, decrease the Quality/speed value.
5. Drag the Response delay slider to the right. Notice the audible change in the reverb’s delay.

The Acoustic Mirror dialog contains four tabs: General, Envelope, Summary, and Recover. Each tab contains
controls that allow you to precisely configure the effect as well as recover custom impulses. Notice that the
Acoustic Mirror dialog contains the preset and preview controls found in all of the Sound Forge process and
effect dialogs. For more information, see Applying presets on page 163 and Previewing processed audio on page 165.

General tab controls
The following sections describe all controls located in the General tab.
Impulse

The Impulse drop-down list allows you to specify an impulse file from a list of those previously used. Clicking
Browse displays the Open Impulse File dialog and allows you to locate an impulse file from your local system
or network.
Response width

You can use the Response width slider to create some simple stereo expansion and stereo collapsing effects.
This control’s default setting of 50 represents normal stereo operation and is recommended to maintain the
stereo field of the impulse response. A higher setting expands the stereo field, but may result in an unnatural
sounding effect. Lowering this setting narrows the stereo field. A setting of 0 is essentially mono.
Response delay

The Response delay slider controls the time, in milliseconds, that elapses between the dry signal and the
processed output. This control can be used to create interesting effects and add new dimensions to an
acoustic signature. Configuring this control with a positive value results in the processed output following
the dry output. A negative value results in the processed output preceding the dry signal, or a pre-delay.
Pan (left to right)

The Pan slider controls the balance between the left and right channels in stereo files. The default value is 0
and indicates a typical center position.
Dry Out

The Dry Out fader controls the amount of unprocessed signal mixed into the output.

CHP. 12

USING ACOUSTIC MIRROR AND WAVE HAMMER

208

Wet Out

The Wet Out fader controls the amount of processed signal mixed into the output.
Apply envelope and limit decay to (seconds)

When you select this check box, the length of the impulse is limited to the time specified in the adjacent
box. Limiting the length of an impulse file shortens the decay of the reverberation and decreases the amount
of processing required.
In addition, selecting this check box results in the impulse fading according to the Envelope Graph configured
on the dialog’s Envelope tab. For more information, see Envelope Graph on page 209.
Low-shelf start frequency/High-shelf start frequency

Acoustic Mirror high- and low-shelving filters to allow you to tailor the frequency response of the impulse.
Notice that you can adjust the cutoff frequency and boost/attenuation of each filter independently.
Convert mono to stereo

Selecting the Convert mono to stereo check box converts a mono signal to stereo output. If the impulse file is
in stereo, selecting this check box imparts a pseudo-stereo effect on the mono input.
Quality/speed

The Quality/Speed slider allows you to strike a balance between the quality and speed of the audio processing.
Lowering this value immediately affects the frequency response of the impulse. The processed signal sounds
dull and high frequencies sound unnatural. At very low values, the length of the impulse is shortened. When
this control is set to a high value, the audio quality is excellent, but the processing takes longer.
If you are experiencing difficulty previewing processing in real-time, decrease the Quality/speed value.
However, you must return this value to 5 prior to actually processing the file to output the highest possible
quality.

Envelope tab controls
The following sections describe all controls located on the Envelope tab.

Impulse

This control is identical to the Impulse drop-down list on the General tab. This allows you to view the
envelope graphs for the specified impulse file. For more information, see Impulse on page 207.

Wet Out

This control is identical to the Wet Out fader on the General tab. For more information, see Wet Out on page
208.
Apply envelope and limit decay

This control is identical to the Apply envelope and limit decay check box on the General tab. For more
information, see Apply envelope and limit decay to (seconds) on page 208.
Envelope Graph

Selecting the Apply envelope and limit decay check box turns on the Envelope Graph. You can use the envelope
graph to decrease the length of the specified impulse file, which consequently decreases the reverberation
decay time and processing time. You can also use the envelope graph to apply fades to the specified impulse
file.

The horizontal axis of the graph represents the time of the impulse file and the vertical axis represents peak
amplitude in dB. Specifying an impulse file from the Impulse drop-down list automatically displays its
envelope in the graph.
Note: If the impulse file is greater than 6 seconds in length, it

does not display in the envelope graph.
Envelope points

Envelope points are used in the envelope graph to specify a fade curve. The fade amount can vary from 0%
to 100%. You can create, delete, and arrange envelope points just as you can in all of the Sound Forge
envelope graphs. For more information, see Envelope graphs on page 44.
Note: The fade value at any point in a curve does not use
the same vertical logarithmic (dB) scale used for displaying
the impulse file.

Adjusting the impulse length

Drag the vertical Envelope Endpoint line to the desired location. The Envelope Endpoint repositions and the
length of the impulse adjusts.

Repositioning the envelope endpoint line

speed on page 208.

Recover tab controls
The Recover tab is used in creating your own impulse files. For more information, see Creating impulse files on
page 212. The following section describes all controls located on the Recover tab.
Recorded file

The Recorded file box allows you to select the file containing the test tone recorded in the field. You can
enter the path directly into the box or click Browse to locate and select a file.
Test file used

The Test file used box allows you to select the file that was used as a test tone. You can enter the path directly
into the box or click Browse to locate and select a file.
Note: You should use one of the test files included in the
Acoustic Mirror Impulse Files\Test Tones

folder on the Sound

Forge CD-ROM.
Impulse output

The Impulse output box allows you to specify where the recovered impulse response file is saved. You can
enter the path directly into the box or click Browse to locate and select a folder.
Remove very low frequencies

When you select this check box, very low frequencies (which are typically comprised of noise) are removed
from the impulse response. This increases the impulse response’s signal-to-noise ratio.

Recover Impulse

Clicking the Recover Impulse button starts the impulse recovery process. After the process is complete, an
impulse file is created and saved in the folder specified in the Impulse output file box.
Impulse recovery mode

You can choose from three Impulse recovery mode options to determine the method used to recover the
impulse: Use the start and end of the recorded file as timing spikes, Auto-detect timing spikes, or Do not use timing
spikes. Each of these modes is described below.
Use the start and end of the recorded file as timing spikes

This option specifies that the beginning and end of the recorded file are used as timing spikes. This option is
recommended for the best results during impulse recovery.
You must trim the file as close to the timing spikes as possible for this method of recovery to work most
effectively. The first sample of the file should contain the start of the first spike and the last sample of the file
should contain the start of the second spike. Therefore, most of the second spike is deleted.
Auto-detect timing spikes

This option specifies that the timing spikes exist near the start and end of the recorded file and that they
should be auto-detected. Timing spikes are used to correct for clock or tape speed mismatches. If you have
not trimmed the recorded file so that the timing spikes are at the very beginning and end, select this option
for the best results.
With this option, you need only ensure that the first spike occurs within one second of the start of the file
and that the second spike exists in the file. To improve detection accuracy, you can also boost the level of
the start and end spikes in the recorded file.
Tip: If the spike’s level is close to the noise floor, select the
Use the beginning and end of the recorded file as timing spikes

option.
Do not use timing spikes

This option specifies that no timing spikes are used. This is the least desirable option as no timing
information is used. To use this option, you must trim the recorded file so that the test tone starts and ends at
the start and end of the file, with no blank audio before or after. This option should only be used if the
timing spikes are lost in the recording or if you are certain that the play and record clocks are synchronized
(such as when using an ADAT).

Creating impulse files
You can obtain impulse responses from anything that accepts test tone input and supports recording the
output. This includes physical spaces as well as electronic audio equipment. Creating custom impulse files
requires planning, work, and additional audio equipment.
Note: Impulses derived from electronic devices that produce
nonlinear effects such as overdrives, distortion pedals, pitch
shifters, harmonic enhancers, chorus pedals, or flange pedals
cannot be modeled using the Acoustic Mirror tool. While they
produce interesting effects, the acoustic signature cannot be
correctly replicated.

What you need to create custom impulses
The equipment required to create custom impulses depends upon whether you want to create the impulse
from a physical acoustic space or from a piece of equipment. Regardless of the method, you need a playback
device that reproduces test tones and a recording device that has microphone or line-level inputs. Be aware
that the quality of the impulse is directly affected by the quality of your playback and recording devices. The
flatter your system’s response, the more accurate the impulse response.
Recovering an impulse from an acoustic space

To recover an impulse from an acoustic space, you need the following equipment:
• A playback device and speakers
• A stereo pair of microphones to record the test tone
• A recording device for recording the signal captured by the microphones
Recovering an impulse from an electronic device

To recover an impulse from an electronic device, you need the following equipment:
• A playback device that connects to the device’s inputs
• A recording device that connects to the device’s outputs

Recording the impulse in an acoustic space
Once you have assembled the required equipment, you are ready to begin recording the impulse. The
following sections describe the typical impulse recording procedure.
Transferring the test tone

The first step in recording the impulse is to transfer the desired test tone to your playback device. The Sound
Forge CD-ROM contains two test tones: a 24-second test tone and a 48-second test tone. We typically
recommend that you use the 24-second tone because longer tones result in greater signal-to-noise ratios. The
48-second tone should be used in particularly noisy environments or when the decay time of the acoustic
space is greater than six seconds.
Tip: There are spikes at the beginning and end of each test

tone. You should include the spikes in the recording to simplify
the recovery of the impulse in the later stages of the process.

USING ACOUSTIC MIRROR AND WAVE HAMMER

CHP. 12

213

Placing equipment

When recording the test tone in an acoustic space, you must determine where to place your playback system,
speakers, microphones, and recording system to produce optimal results. Microphone placement is crucial to
the quality of the impulse. The distance between the speakers and the microphone is the perceived distance
of audio processed with the impulse you create. For example, if you record the test tone with the speakers
positioned 100 feet from the microphones, all sounds processed with the resulting impulse sound as if they
are originating 100 feet from the listener.
Setting levels

After the devices are positioned, you should begin playback of the test tone. The test tone should be played
as loudly as possible (or practical) to produce the best signal-to-noise ratio. With the test tone playing at
optimum volume, set the levels on the recording device. Recording devices levels should also be set as high
as possible, but not permitted to clip or distort. Safe levels are determined by whether you are recording to an
analog or digital medium.
Recording the test tone

Begin recording on the recording device and begin playback of the test tone. Remember to include the
spikes at the beginning and end of the test tone. Record the test tone several times using the initial setup,
then move the microphones and record the test tones several more times. Continue moving the
microphones and recording until you have exhausted the space’s acoustic possibilities. Recording impulses in
this manner provides you with several distinct impulses for each space.

Recording the impulse through an electronic device
The recording process is similar if you are recording the output of an electronic device, but there are no
speakers or microphones to be placed.
Using the appropriate cables, connect the playback system’s outputs to the electronic device’s inputs and the
electronic device’s outputs to the recording system’s inputs. Once the devices are connected, play the test
tone through the electronic device and record its output on the recording system.
Other impulses

Any number of methods can be used to create an impulse, including starter pistols, clap boards, or even a
sharp hand clap. The drawback of these “impulse generators” is that they add their own coloration to the
sound. For best results, we recommend using the test tones included on the CD-ROM.

Recovering the impulse
Once you have recorded your test tones, they must be processed and converted into impulse responses. The
following sections describe the typical impulse recovery procedure.
Trimming the test tone
1. Open your test tone file (the “room processed” output test tone) in the software.
2. Locate the first timing spike and delete all audio before it. Cut as close to the beginning of the timing

spike as possible, but do not delete the spike itself.
3. Locate the second timing spike and delete all data from the start of the second spike to the end of the file.

Again, cut as close to the start of the timing spike as possible.
You should now have an audio file with a spike at the beginning, a test tone, and silence.
4. Save the test tone file.
Naming, configuring, and recovering the impulse
1. From the Effects menu, choose Acoustic Mirror. The Acoustic Mirror dialog is displayed.
2. Click the Recover tab.

Recover tab

3. Enter the name and path of your impulse file in the Recorded File box or click Browse and locate the file.
4. Enter the name of the original test tone file in the Test file used box.
5. Enter the desired name for the impulse response file to be created in the Impulse output box. If necessary,

click Browse and specify the folder in which the impulse file will be saved.
6. Select the Remove very low frequencies check box.
7. If the recorded file was trimmed exactly to the start and end spikes using the procedure described

previously, choose Use start and end of the recorded file as timing spikes from the Impulse recovery mode dropdown list. For more information, see Trimming the test tone on page 214.
8. Click the Recover Impulse button to begin recovering the impulse.

After processing is complete, you can open the impulse file in the Sound Forge software and perform any
necessary trimming or editing. For more information, see Trimming the impulse file on page 215.

USING ACOUSTIC MIRROR AND WAVE HAMMER

CHP. 12

215

Trimming the impulse file
After the impulse file is recovered, it may still require minor trimming. In general, you should try to make
the impulse response as short as possible to increase processing speed when using the Acoustic Mirror tool.
Impulse files greater than 131,071 samples (about 3 seconds) in length require substantial processing time.
When possible, trim the impulse response to less than 65,535 samples (about 1.5 seconds). In addition, we
recommend fading the tail of the impulse. Of course, this is not always an option when dealing with spaces
that produce extended reverberations.
1. Open the recovered impulse file in the Sound Forge software and play it.
2. Delete any silence or low-level noise that occurs before or after the actual audio data. Typically there are

between 900 and 1100 samples of data at the beginning of the impulse that should be removed.
3. Save the trimmed impulse response file using the standard WAV format.
Tip: To prevent phase problems when mixing the dry and wet

signals, you may also want to verify the phase of the impulse
file. The file should begin by going positive (above the
centerline). If the impulse file has a negative (below the
centerline) phase, choose Invert/Flip from the Process menu.

Adding summary information to your impulse file
If you plan on sharing impulses with other Sound Forge users, we recommend adding summary information
and BMP images to your files.
1. Open the impulse file in the software.
2. From the File menu, choose Properties. The Properties

dialog is displayed.
3. Click the Summary tab.
4. Enter the appropriate information in each box.
5. Click the Picture button. The Open Picture dialog is

displayed.
6. Locate the desired image and click Open. The image is

linked to the impulse file.
7. Click OK.
Note: If you are using a palletized display setting (256 colors
or less) and attach a bitmap to an impulse file, the bitmap
colors are distorted when viewed in the Acoustic Mirror tool.
This is because the bitmap is converted using the default
palette at the time of attachment, which is not optimal. For
this reason, you should set the display settings to at least a 16bit palette prior to attaching bitmaps to impulse files.

Properties dialog with an attached image

Using the new impulse file
To use your new impulse file, open the Acoustic Mirror dialog and choose it from the Impulse drop-down list
as you would any other impulse file. If you performed the previous procedures properly, the custom impulse
file should realistically recreate the reverberation characteristics of the electronic device or acoustic space.

Using impulse files in creative ways
Now that you understand the use and creation of impulse files, you may want to begin using the Acoustic
Mirror tool in more interesting ways than simply applying an impulse to an audio file. The following sections
describe some creative and advanced uses for Acoustic Mirror technology that can contribute to the
professionalism of your work.

Processing individual audio elements
Instead of applying an impulse file to an entire song, try applying an impulse to individual elements of the
song. Applying an impulse to specific notes, chords, riffs, or phrases can quickly change the dynamics of a
song. This technique is possible because the tail of processed audio is automatically mixed with the adjacent
unprocessed audio.

Adding realistic stereo to mono recordings
You can give mono recordings realistic stereo characteristics by selecting the Convert mono to stereo check
box in the General tab of the Acoustic Mirror dialog when applying the specified impulse file. The stereo
image produced using this method is virtually indistinguishable from an actual stereo recording.
If you choose to use the Acoustic Mirror effect for stereo simulation, you may find the output too
reverberant. If this is the case, decrease the Apply envelope and limit decay value. Frequently, setting this value
to as little as 0.1 seconds provides stereo realism without adding a distracting amount of reverb.

Creating special effects
Processing an audio file using a non-impulse WAV file can produce any number of unexpected and
interesting special effects. To demonstrate this concept, create several short (less than 12 seconds) audio files
using the FM Synthesis tool and save them as individual WAV files. Now choose any of these files from the
Impulse drop-down list and preview the results.
We have included several short files on the Sound Forge CD-ROM to allow you to experiment with this
technique. After some experimentation, you should begin to notice a few general rules regarding this use of
the tool:
•
•
•
•

Impulse files that cover the entire frequency spectrum prevent the output from sounding too filtered.
Using a frequency sweep as an impulse creates a frequency-dependent delay effect.
Panning within the impulse causes the stereo image of the output to flutter between channels.
Using staccato sounds (such as drum hits) creates a variety of echo effects.

Recreating spaces for foley effects and dialog replacement
Frequently, dialogue recorded in the field is rendered unusable by ambient noise. If you are shooting in the
field and realize that overdubbing will be necessary, you should create an impulse in each filming location.
This allows you to overdub dialog during post-production that is indistinguishable from dialog recorded on
location.
If you intend to use the Acoustic Mirror effect as a film/video post-production tool, there are some factors to
keep in mind:
• Distance information is determined by the distance between the source and the microphone when
creating the impulse. Record multiple impulses at various distances for each location to create realistic
dialog effects when matching audio processing to approximate camera positioning.
• The frequency response of the human ear changes as the volume of a sound increases. As a result, impulses
created from a significant distance may sound unusual at high volumes.
• Placing a microphone off center allows you to create directional information in the recovered impulse. For
example, placing a microphone to the left of the speaker produces an impulse that approximates a source
located on the left side of the screen.

Panning with head-related transfer functions
A head-related transfer function (HRTF) contains the frequency and phase response information required to
make a sound seem to originate from a specific direction in a three-dimensional space. The Acoustic Mirror
Impulse Files\HRTF Impulses folder on the Sound Forge CD-ROM contains a collection of impulse files that
contain directional cues.
To achieve optimal results using these impulse files, the original file should be mono and playback should be
monitored using headphones. To begin, convert the mono file to stereo by replicating the mono signal in
each channel. After the audio is converted to stereo, choose an impulse file from the HRTF Impulses folder.
You will notice that the HRTF Impulses folder is further divided into Left and Right directories. Opening the
desired folder displays the available impulse files, all of which are named based on their elevation (up or
down) and azimuth (left or right) angles in degrees. The following table provides some examples:

Troubleshooting the Acoustic Mirror effect
The following sections describe problems that may be encountered when working with the Acoustic Mirror
tool.

Stuttering during real-time previewing
It is not uncommon to experience problems when previewing processing in real-time. The following sections
contain several suggestions to remedy the situation.
Lower the Quality/speed setting

Lower the value of the Quality/speed control on the General page. When previewing lengthy impulse
responses, a setting of 1 or 2 may be necessary; however, the quality suffers. This setting should always be
returned to 5 prior to processing to maintain effect quality.
Increase the DirectX buffering size
1. Open the Acoustic Mirror dialog.
2. Right-click an empty area of the dialog outside of the four tabs and choose Configuration from the shortcut

menu. The Real-Time Preview Configuration dialog is displayed.
3. Reconfigure the Buffers to process per second and Total playback buffers controls. Typically, lowering the
Buffers to process per second

value and increasing the Total playback buffers value reduces gapping during

real-time previewing.
Close all memory-intensive applications

Real-time previewing may be limited by any additional applications operating on the desktop. To avoid this
situation, close all memory-intensive applications prior to using this effect.

CHP. 12

USING ACOUSTIC MIRROR AND WAVE HAMMER

218

Add additional RAM to the system

We recommend at least 64 MB of RAM to operate Sound Forge software and its related tools.
Add a faster floating point arithmetic processor

Many high-speed processors are still lacking in speed when processing floating point arithmetic. We
recommend using high-speed processors that provide exceptional floating point arithmetic for reliable realtime previewing.

Impulses do not recover properly
If you experience problems recovering custom impulse recordings, verify each of the following:
a. Verify that you have trimmed the recorded test tone based on the mode chosen from the Impulse
recovery mode

drop-down list. For more information, see Trimming the test tone on page 214.

b. Verify that the second spike is present in the recorded test tone if the Auto-detect timing spikes options is

specified.
c. Verify that the file specified in the Test file used box is the exact test tone used to make to field

recording and that neither its length or data has been changed.
d. If the impulse still does not recover properly in Auto-detect timing spikes mode, normalize the spikes in

the recorded test tone file. This should aid the auto-detect algorithm in detecting the timing spikes and
recovering the impulse.

Recovered impulse is too noisy
To maximize the impulse’s signal-to-noise ratio, you should verify that the field recording’s noise floor is not
too high. When recording in noisy environments, increase the test tone’s amplitude until the test tone is at
least 25 dB louder than the noise floor. At least 40 dB of signal-to-noise is recommended for optimal
impulses. If you cannot avoid noise when recording in the field, Sony Media Software’s Noise Reduction tool
can salvage a session.
Speaker nonlinear distortion can also cause noisy impulses. The most common source of nonlinear distortion
is loudspeaker harmonics. Most speakers display substantial harmonic distortion at low frequencies. For
example, when you play a 60 Hz tone, the speaker vibrates at 60 Hz, but also outputs lower-level audio at
multiples of 60 Hz (120, 180, etc.). The impulse recovery method greatly minimizes these low-frequency
distortions; however, inexpensive tweeters often display substantial high-frequency distortion that can
disrupt the recovery process. When possible, use high-quality components and do not overdrive the speakers.

Error message explanations
The following sections briefly describe Acoustic Mirror error messages that you may encounter.
The selected file is not a valid test file

The file specified in the Test file used box is not a test tone file included on the Sound Forge CD-ROM.
The level of the first spike is low. Do you wish to use it as a timing spike?

This typically means that no actual timing spike was detected. Verify that the first spike is within one second
of the start of the recorded file. If the recording is noisy and the spike is not very pronounced, you can aid
detection by muting the audio immediately before and after the spike.
An error occurred reading the test tone file

Either the test tone file was not found or is not a valid test tone file. Always use a test tone file provided on
the Sound Forge CD-ROM.

The selected Recorded file is much smaller than the test tone size

This may indicate that the test tone or the recorded file specified in the Recover tab is not correct. Verify
that the length of the recorded file roughly the same size as the test tone file.
The end spike was not found

Verify that the spike following the test tone is present in the recorded file when recovering impulses in Autodetect timing spikes mode.

What is the Wave Hammer plug-in?
Sony Media Software’s Wave Hammer DirectX plug-in is an audio mastering tool consisting of a classic
compressor and a volume maximizer.
The Wave Hammer tool can be used in any Microsoft DirectX-compatible host application (for example,
Sound Forge and ACID® Pro software), and the quality and functionality of the Wave Hammer plug-in is
the same in each host application; however, the method of previewing effects is different. Consult your host
application’s documentation to determine the available previewing methods.

Displaying the Wave Hammer plug-in
To display the Wave Hammer tool, choose Wave Hammer from the Effects menu.

The Wave Hammer dialog
The Wave Hammer controls are divided into two tabs: Compressor and Volume Maximizer.

Compressor tab
The controls on the Compressor tab are used to compress the audio signal. When applied properly,
compression reduces the dynamic range of audio and allows you increase overall loudness. Compression has
various uses. For example, applying heavy compression at a low threshold to electric guitar produces
distortion.

Compressor tab

CHP. 12

USING ACOUSTIC MIRROR AND WAVE HAMMER

220

Threshold

The Threshold fader is used to adjust the audio level at which compression is applied. Audio with levels
higher than the Threshold value are compressed, while audio at levels lower than this value pass through the
compressor uninterrupted.
Ratio

The Ratio slider determines the amount of compression applied to audio signals surpassing the threshold. A
ratio of 1:1 applies no compression to audio surpassing the threshold, while a ratio of 2:1 requires a 2 dB
increase in actual volume to raise the processed volume 1 dB. A ratio of Inf:1 is considered a limiter.
Output gain

The Output gain fader allows you to determine how much the audio signal is boosted following its
compression.
Attack time

The Attack time slider allows you to determine how soon after rising above the threshold the audio signal is
attenuated.
Release time

The Release time slider allows you to determine how soon after falling below the threshold the audio signal
attenuation is interrupted.
Smart release

The Smart Release slider allows you to configure the compressor to automatically increase the release time for
sustained notes and decrease the release time for sharp transients. Setting this value higher increases the
internal variability of the specified Release value.
Generally, louder overall audio levels can be achieved with lower Release values. However, low Release
values can also lead to an increase in “pumping” artifacts. Configuring a Smart Release value increases the
release time during sustained sounds, thereby preventing release changes from occurring too rapidly.
Scan mode

The Scan mode radio buttons allow you to specify whether Peak or RMS mode is used to determine the
loudness of an audio file, which in turn determines the amount of compression that is applied. When
compressing in Peak mode, the compressor applies compression where it detects audio signal peaks that
surpass the threshold.
However, when compressing using RMS mode, the compressor processes the audio using the detected
average RMS value of the entire file. The Root Mean Square (RMS) of audio is a measure of its intensity
over a period of time. Therefore, the RMS level of audio corresponds to the loudness perceived by a listener
when measured over small intervals of time. As a result, rapid transient peaks may not be processed when
compressing in RMS mode.
Auto gain compensate

When you select the Auto gain compensate check box, the compressor output is boosted by a constant amount
derived from the Threshold and Ratio settings. This option prevents a loss in overall level when compressing
audio.
Tip: When using the Auto gain compensate option, the
Output gain fader should be used to fine tune the signal output

level.

USING ACOUSTIC MIRROR AND WAVE HAMMER

CHP. 12

221

Use longer look-ahead

When you select the Use longer look-ahead check box, the compressor scans farther ahead in the incoming
audio to determine how much compression is needed. This results in compression being applied before the
threshold-surpassing audio actually occurs, thereby allowing for a slower Attack time value. However, the precompression effect (fades that occur prior to attacks) of this option may be distracting.
Smooth saturation

Selecting the Smooth saturation check box lowers the amount of distortion caused when applying heavy
compression. When this option is turned on, the compressed audio sounds warmer and not overly bright.
Input/Output meter

This meter allows you to monitor the level of the incoming and outgoing signals. When the Input button is
displayed, the meters display the incoming signal level. Clicking Input toggles the button to an Output button
and displays the outgoing signal level. Clicking Output returns you to the incoming signal display.
Attenuation meter

This meter allows you to monitor the audio signal attenuation derived from the current settings.

Volume Maximizer tab
The controls on the Volume Maximizer tab are used to limit the peak amplitude of an audio file or to boost the
overall level without clipping the waveform and distorting the audio.

Threshold

The Threshold fader is used to adjust the audio level at which the volume maximizer activates. Audio with
levels higher than the Threshold value are affected, while audio at levels lower than this value pass through
the volume maximizer uninterrupted.
Output level

The Output level fader allows you to determine the level to which peaks above the Threshold setting are
boosted or cut.
Release time

The Release time slider allows you to determine how soon after falling below the threshold the audio signal
attenuation is interrupted.

Use longer look-ahead

When you select the Use longer look-ahead check box, the volume maximizer scans farther ahead in the
incoming audio to determine the amount of limiting that is needed. This results in limiting being applied
before the threshold-surpassing audio actually occurs. However, the pre-limiting effect (fades that occur prior
to attacks) of this option may be distracting.
Input/Output meter

This meter allows you to monitor the level of the incoming and outgoing signals. When an Input button is
displayed, the meters are displaying the incoming signal level. Clicking Input toggles the button to an Output
button and displays the outgoing signal level. Clicking Output returns you to the incoming signal display.

Working with MIDI/
SMPTE

This chapter describes using Sound Forge® software in conjunction with internal and external MIDI
devices.
MIDI/SMPTE features are available only in the full version of Sound Forge software.

What is MIDI?
The musical instrument digital interface (MIDI) is a set of commands or a language that music software and
hardware use to communicate. The most common way to utilize MIDI is to have a device, such as a MIDI
sequencer, generating and sending MIDI commands to another device, such as a synthesizer.

MIDI triggers
You can use numerous internal and external devices to generate MIDI commands and trigger audio playback
in the software.

Playback versus triggered playback
Procedures in this section use the Sound Forge MIDI Keyboard as the MIDI device for triggering audio
playback.
For more information, see Using the MIDI Keyboard on page 246.
Simple playback

When you click the Play button in the transport bar or playbar, the audio file in the active data window plays
and you hear the audio. MIDI is not involved.
Triggered playback

When the MIDI keyboard triggers playback of the same file, the following items occurs:
• The MIDI Keyboard transmits MIDI commands to the MIDI router.
• The MIDI router transmits the MIDI commands to the Sound Forge MIDI input port.
• The audio file plays.
Note: In the case of triggered playback, MIDI commands
may come from any software or hardware device that
generates MIDI.

CHP. 14

WORKING WITH MIDI/SMPTE

Triggering file playback
Using the MIDI Keyboard or any other MIDI device to trigger audio playback involves three separate
procedures:
• Configuring the MIDI device (in this case, the MIDI Keyboard).
• Enabling MIDI input synchronization.
• Configuring the MIDI trigger.
Configuring the MIDI device

Triggering region playback
Frequently, it is preferable to use a MIDI device to control the triggering of the individual regions within a
file. As in the previous example, the MIDI Keyboard will be used to demonstrate this function.
Note: Before performing this procedure, reset all triggers.
For more information, see Resetting MIDI triggers on page
235.

Configuring region playback triggers
1. Display and configure the MIDI Keyboard. For more information, see Configuring the MIDI device on page

234.
2. Set up the MIDI input synchronization. For more information, see Turning on MIDI input synchronization on

page 234.
3. Open the Voiceover.pca file and display its Regions List.
4. Select the “Wow” region and press Enter . The Edit Marker/Region dialog is displayed.
5. From the Trigger drop-down list, choose MIDI: Note On - Play.

6. Enter 1 in the Channel box and C-4 in the Note box.
7. Click OK. A small musical note appears adjacent to the “Wow” region in the Regions List to indicate that a

trigger has been configured.

A small musical note

CHP. 14

237

Using region playback triggers
1. From the Options menu, choose MIDI In/Out, and choose Trigger from MIDI Timecode from the submenu. A

check mark appears adjacent to the command, indicating it is active and the software is ready to receive
MIDI commands.
2. Click C4 on the MIDI Keyboard. The “Wow” region plays.
3. Click other trigger keys on the MIDI Keyboard and observe how this feature can be used to play regions

on cue or quickly rearrange an audio file.
Note: Only one region can be played at any given time.
Overlapping causes the active region’s playback to be
interrupted and the new region’s playback to begin.

Triggering playback from additional internal/external MIDI devices
The basic concepts of MIDI routing and triggering from the Sound Forge MIDI Keyboard described in
previous sections apply to any hardware or software device capable of generating MIDI commands. Follow
the same basic steps to trigger playback:
1. Install and configure the MIDI controller (refer to the product-specific documentation for installation

procedures).
2. Set up MIDI input synchronization. For more information, see Turning on MIDI input synchronization on

page 234.
3. Configure the MIDI triggers to respond to the corresponding controls on the controller. For more

information, see Configuring the MIDI trigger on page 235.

Advantages of external MIDI controllers
In addition to simple playback, MIDI commands can be used to control a wide array of the Sound Forge
navigation and editing functions. In fact, a quick look at the Event drop-down list in the MIDI Triggers
dialog can provide you with an idea of the power of MIDI commands used in conjunction with Sound Forge
software.
Using external MIDI controller presets

Sound Forge system presets support the sequencer, cursor, dial, and function buttons on the following
external MIDI controllers:
• Roland MCR-8 Multi-Controller
• JLCooper Media Control Station 2
The system presets for these controllers allow you to perform the following actions:
•
•
•
•

Move the cursor using the controller’s dial.

Sound Forge software and MIDI timecode synchronization
MIDI timecode (MTC) is a method of using SMPTE timing signals to synchronize multiple devices.
Although MIDI timecode is typically used to synchronize audio and video, it can also be used to synchronize
playback devices. You can synchronize to external MTC or generate MTC for other devices to follow. For
more information, see SMPTE Timecode on page 317.
You can also specify start times of regions in the Regions List to synchronize digital audio with additional
timed events. For example, if a MIDI sequencer generates SMPTE timecode, you can synchronize to it with
its own SMPTE timecode and initiate region playback at specified times.
MTC synchronization versus Note-On MIDI triggering

Synchronizing to MTC is similar to synchronizing to other MIDI events and can be used in many of the
same situations. The major advantage of MTC synchronization is that it allows for you to specify accurate
SMPTE start times. However, MTC synchronization requires more of your system’s processing power.
When triggering a limited number of sounds in the software from a sequencer, it is preferable to use Note-On
MIDI Triggering. For more information, see Triggering file playback on page 234.

Playing regions using MTC from a sequencer
Triggering region playback in Sound Forge software from a sequencer using MTC involves three procedures:
• Configuring the regions.
• Enabling MIDI input synchronization.
• Configuring the sequencer.
Configuring the regions
1. Open the Voiceover.pca file and view the Regions List and Playlist windows.
2. Select the “Wow” region in the Regions List and drag it to the playlist. The “Wow” region is added to the

playlist.
The “Wow” region is added to the playlist.

3. Select the “Wow” region in the playlist and press Enter . The Edit Playlist dialog is displayed.
4. From the Trigger drop-down list, choose SMPTE: Play at Time. The SMPTE time box is activated.
5. Enter an appropriate SMPTE start time using the hours:minutes:seconds:frames format and click OK. A

small musical note appears adjacent to region in the playlist to indicate that a start time for this region’s
playback is configured.

Playing regions using MTC from an external device
When using a hardware device that generates MTC, the configuration procedure is basically the same as
outlined above. Simply specify the device’s MTC output driver as the Sound Forge MIDI input port in the
Preferences dialog’s MIDI/Sync tab.

Using Sound Forge software to generate MTC for a MIDI sequencer
You can generate MTC for other devices to follow. However, it is important to understand that the software
only generates MTC while playing a file or from a playlist. Generating MTC involves two procedures:
• Configuring the Sound Forge software.
• Configuring the sequencer.
Configuring Sound Forge software
1. Open an audio file.
2. From the Options menu, choose Preferences. The Preferences dialog is displayed.
3. Click the MIDI/Sync tab.
4. Specify the Sound Forge MIDI output that corresponds to the input port of the sequencer and click OK.
5. From the Options menu, choose MIDI Triggers. The MIDI Triggers dialog is displayed.
6. From the Preset drop-down list, choose Reset all triggers to (none). This prevents other MIDI commands

from creating additional triggers.
7. Click OK.
8. From the Options menu, choose MIDI In/Out, and choose Generate MIDI Timecode from the submenu. A

check mark appears adjacent to the command, indicating that the software is ready to generate MTC.
Configuring the sequencer
1. Specify the sequencer’s MIDI input port that corresponds to the Sound Forge MIDI output port.
2. Set the sequencer’s SMPTE offset time value as needed.
Note: Sound Forge software uses 00:00:00:00 as its output
start point, but certain sequencers recommend a SMPTE
offset time of at least four seconds to ensure synchronization.
3. Turn on the sequencer’s MTC input.
4. If required by the sequencer, press the Play button. The sequencer does not begin playback, but switches to

“Waiting for MTC” mode.
5. Start playback of the file in the software. When the SMPTE offset time is satisfied, the sequencer locks to

and follows the MTC generated by the Sound Forge application.

Using Sound Forge software to generate MTC for an external device
To use the software to send MTC to an external device, follow the previous instructions, but configure the
Sound Forge MIDI output port to send directly to the device’s MIDI driver.

CHAPTER

Sampling

15
Used in conjunction with the Sampler Tool, the Sound Forge® software’s powerful editing capabilities allow
you to create, edit, and transfer samples between external and internal samplers. This chapter describes the
procedures used to transfer (dump) samples between the computer and sampler with the Sampler Tool.
The Sampler Tool is available only in the full version of Sound Forge software.

Samplers
Samplers are devices that produce on-demand playback of audio samples at varying pitches. For the purposes
of this manual, we will concentrate on two basic varieties: external samplers and internal samplers.

External samplers
External samplers are typically capable of recording samples or transferring prerecorded samples into their
memory. You can choose between two methods to transfer samples to external samplers:
• MIDI Sample Dump Standard (SDS)
• SCSI MIDI Device Interface (SMDI)
MIDI Sample Dump Standard (SDS)

The MIDI SDS is used to send and receive digital samples using normal MIDI hardware and cable
connections. Due to the limited bandwidth of the MIDI protocol and the large amount of data required by
digital samples, a MIDI SDS transfer can be time consuming. Furthermore, SDS is limited to mono samples,
though certain samplers allow two mono samples to be joined as a stereo sample.
SCSI MIDI Device Interface (SMDI)

The SCSI MIDI Device Interface (SMDI) allows music hardware and software to communicate using SCSI
hardware and cables. Because SCSI hardware has a greater bandwidth than MIDI, SMDI transfers are
considerably faster than SDS transfers. In addition, SMDI supports mono and stereo sample transfers.

CHP. 15

SAMPLING

242

Internal samplers
Internal samplers are cards installed in your system that, unlike typical sound cards, actually allow sounds to
be downloaded into memory and played at varying pitches to simulate a musical instrument.
Using an unsupported internal sampler

If you have an internal sampler not directly supported by the Sampler Tool, you have two options:
• Use the MIDI SDS transfer protocol.
• Use an open loop transfer.
Note: If you have a Windows-compatible internal sampler,
contact the manufacturer about supporting SDS in Windows
drivers.

Configuring the Sampler Tool
Configuring the Sampler Tool is fairly straightforward, especially if the desired configuration exists in the list
of presets.
1. From the Tools menu, choose Sampler. The Sampler dialog is displayed.

2. From the Configuration drop-down list, choose the desired configuration. If the desired configuration is not

listed, you must create it in the Sampler Configuration dialog. For more information, see Creating a sampler
configuration on page 243.
3. Enter a value in the Logical send/receive sample number box.

This value determines the number that the sampler uses as its location reference when sending or
receiving samples. This number can be biased for specific samplers with the Sample bias option in the
Sampler Configuration dialog. For more information, see Creating a sampler configuration on page 243.
4. Begin the process of sending or receiving samples. For more information, see Sending and receiving samples on

page 245.

SAMPLING

Creating a sampler configuration
The Sampler Configuration dialog allows you to create new sample configurations that can be saved as
presets and accessed from the Sampler dialog. Creating new custom configurations requires you to specify the
sampler and sample transfer mode. However, the process of creating a custom sampler configuration differs
based on which transfer mode is used.
1. From the Tools menu, choose Sampler. The Sampler dialog is displayed.
2. Click the Configure button. The Sampler Configuration dialog is displayed.

The Sampler Configuration dialog

3. From the Sampler model drop-down list, choose the appropriate sampler. If the desired sampler is not

included in the drop-down list, choose the generic SMDI or SDS capable sampler option. If the sampler
supports the specified protocol, the Sampler Tool should interface with the sampler.
4. Specify input/output settings for the sampler:
If
Your sampler uses MIDI/SDS transfer

Your sampler uses SCSI/SMDI transfer

Then
Select the MIDI radio button and choose
input and output ports in the MIDI In and
MIDI Out boxes
Select the SCSI radio button and select
your sampler in the Sampler box.

Note: The Sampler box lists all devices connected to the

selected SCSI host, including devices that are not samplers.
5. If desired, enter a value in the Sample bias box. Sample bias is a user-specified value that is added to the

logical sample number to determine the actual sample number used for sending or receiving.
Additionally, sample bias can be used to define unique biases for multiple projects. For example, when
composing multiple pieces using different samples, it is possible to create unique sampler configurations
for each project. Simply establish a unique sample bias to segregate the samples within the sampler.
6. Enter a value in the MIDI channel box to specify which MIDI channel (1-16) is used when transferring

samples.
7. Select the Open loop check box if you want to send SDS sample data immediately upon clicking the Send
Sample button.

CHP. 15

This is an unconditional transfer of sample data (no handshake).

SAMPLING

244

8. Select the Send request when retrieving samples check box if you want the Sampler Tool to send a request

for the sample to the sampler when you click Get Sample.
Clearing the Send request check box requires that the sample transfer be initiated from the sampler, even
after you click Get Sample. Typically, pressing the appropriate button on the sampler satisfies this request.
9. Select the Wait for request when sending samples check box if you want the Sampler tool to wait for the

sampler to request the sample transfer before sending the sample, even after you click Send Sample.
Typically, pressing the appropriate button on the sampler satisfies this request.
Clearing the Wait for request check box configures the Sampler Tool to send the sample as soon as you click
Send Sample.

Open loop versus closed loop
Open loop describes a unidirectional communication protocol. When the Open loop check box is selected,
the source transmits all data to the destination without listening for instruction from the destination. The
destination has no control over how the data is sent and cannot ask for information to be repeated. This lack
of feedback makes open-loop transfers prone to error.

The Open Loop check box in the
Sampler Configuration dialog

If the Open loop check box is cleared, the communication protocol is referred to as closed loop. A closed loop
allows information to flow in both directions. Using closed-loop transfers, the source sends data in small
packets and the destination, upon receiving the packet, either retains the data or discards the packet and
requests the data to be resent. Using closed-loop protocol, the source does not send the next packet of data
until the destination requests it. This makes closed-loop transfers more reliable than open-loop transfers.
In addition to being less reliable, open-loop transfers are slower than closed-loop transfers, especially when
sending samples using the Sampler Tool. This is due to intentional delays placed between data packets to
compensate for varying sampler speeds. Closed-loop transfers typically guarantee the most efficient timing
between packets.
If possible, avoid using an open loop to receive samples from a sampler. The Sampler Tool cannot control
the flow of data packets and there is a high probability that data will be missed.
Tip: Open-loop transfers can be useful when you do not have

enough cables to connect both the MIDI input and MIDI
output ports.

MIDI unity note and Fine tune
Once you specify a configuration in the Sampler dialog, the Sampler area near the bottom of the dialog
displays all relevant sampler configuration information.
The bottom pane of the dialog contains two additional parameters: MIDI unity note and Fine tune.

MIDI unity note

The MIDI unity note value indicates the pitch to which the sample is tuned.
Fine tune

The Fine tune value indicates any minor tuning differences (measured in cents) in the sample.
Editing MIDI unity note and Fine tune

Both values can be edited and used with samplers that support tuning information by choosing Edit Sample
from the Special menu.
Note: The software does not use this information.

Using the MIDI Keyboard
With the MIDI Keyboard, you can control internal/external synthesizers and samplers from the Sound Forge
application. The MIDI Keyboard can also be used to listen to the sounds on a synthesizer or in the synthesis
section of the sound card.

3. Configure the MIDI input channel of the selected device to correspond to the keyboard’s output channel.
Note: Most MIDI devices are configurable to accept MIDI

commands on any channel.

Troubleshooting the MIDI Keyboard
If after configuration, the keyboard fails to produce sound, check the following items:
• Verify that the output velocity of the keyboard is set to a value greater than 100.
• Verify that the MIDI input channel in the sound module is set to the same channel as the keyboard.
• Verify that the device is configured to receive MIDI input.
• Verify the device output volume level.
• Verify external MIDI connections, if applicable.

Specifying instruments
1. Choose Send Program Changes from the MIDI Out button

menu. A check mark appears adjacent to the
command to indicate that this option is turned on. If this option is turned off, patches cannot be
switched.

2. From the Voice drop-down list, choose the new voice and click any key.
Note: Patch names are arranged as specified in the General
MIDI Standard. For synthesizers not using the General
MIDI convention, use the patch number instead of the
instrument name.

Generating chords
You can also generate chords instead of single notes by choosing a chord structure from the keyboard’s Note/
Chord drop-down list. Chords are generated using the specified note as the root of the chord or interval.

Setting up MIDI/SDS hardware
To use MIDI/SDS protocol with an external sampler that supports MIDI/SDS, you must install a MIDI card
with MIDI input and output ports in the system.
1. Using a MIDI cable, connect the MIDI output port of the sampler to the MIDI input port of the MIDI

card.
2. Connect the MIDI input port of the sampler to the MIDI output port of the card.
Note: This is the same configuration used to connect a

MIDI keyboard to a computer for sequencing.
Internal samplers do not require a MIDI card and MIDI cables; however, an open-loop protocol may be
required when sending samples to an internal sampler. The sampler’s documentation should specify the
requirements for performing SDS transfers if the sampler supports this action.

Troubleshooting MIDI/SDS with open loop
Open-loop transfers, while not recommended for sending or receiving samples, can assist you in
troubleshooting SDS hardware setup problems. If the Sampler Tool does not transfer data to (or from) the
sampler, select the open-loop option and attempt single cable transfers. If open-loop transfers are successful,
but closed-loop transfers are not, any of the following items may be the cause:
• The sampler does not support closed-loop transfers (handshaking).
• One or more of the MIDI cables or connections is faulty.
• The MIDI card is not receiving MIDI input (send) or sending MIDI output (receive). Interrupt conflicts
are common for MIDI input.

Setting up SCSI/SMDI hardware
To use the SCSI/SMDI protocol with an external sampler that supports the SCSI/SMDI protocol under
Windows 98SE, Windows Me, Windows 2000, or Windows XP, only a compatible SCSI adapter is needed.
The computer and sampler must be powered-down prior to connecting or disconnecting SCSI cables to
prevent damage to the computer and/or hardware.

SAMPLING

CHP. 15

249

Troubleshooting SCSI/SMDI
A brief description of some common problems encountered with SCSI and samplers follows.

Conflicting SCSI IDs
When connecting devices on a SCSI chain, each device must have a unique device identifier (ID). SCSI
allows for up to eight unique ID values, numbered 0 to 7. Typically, device ID 7 is used for the internal SCSI
controller card, leaving ID 0 through 6 for other devices.
Note: The ID of a bootable SCSI hard drive must be set to

0.
The following table describes a typical SCSI configuration:
ID

Device(s)

0
1
2-6
7

Hard Drive
CD-ROM Drive
Samplers
SCSI Controller Card

Periodic transfer failures
Messages such as “The SCSI Device is not responding” or “A problem was encountered while transferring
the sample” may indicate a problem with a SCSI bus.
1. From the Tools menu, choose Sampler. The Sampler dialog is displayed.
2. Click Configure. The Sampler Configuration dialog is displayed.
3. Repeat the selection of the SCSI host. This causes a series of SCSI commands to be executed that may

settle the bus.
If the problem persists, power-down and restart all equipment.

Sampler is recognized but does not transfer reliably
The following items are possible causes of unreliable SCSI transfers.
Synchronous transfer mode

Select samplers (the Kurzweil K2000 among them) do not operate properly if there is a SCSI device set to
synchronous transfer mode on the same SCSI chain. SCSI hard drives and CD-ROMs often have the option
of using a synchronous transfer mode. If there is a host versus device synchronous transfer option, select the
host option. Refer to the SCSI device’s documentation for more information.
SCSI termination

If the SCSI chain is not properly terminated, unreliable SCSI transfers may be experienced. Refer to the
SCSI card and SCSI device documentation for more information.
Long or faulty SCSI cables

SCSI cables that are very long or not properly shielded may not operate reliably. In addition, do not use
cables that are not certified SCSI cables.

Adaptec 1540/1542CF does not recognize a sampler

If the Adaptec 1540/1542CF does not recognize the sampler, a change may be required in the configuration
of the Adaptec controller. Some samplers do not operate when the Reset SCSI Bus at Power-On option of the
Adaptec controller is turned on. This is the default operation for the 1540/1542CF and must be turned off to
allow the system to work with the sampler.
Note: Turning off the Reset SCSI Bus at Power-On option

may keep other devices on the SCSI chain from resetting
correctly when using the system’s soft boot feature. Other
systems may freeze temporarily. To guarantee that devices
are reset when rebooting with this option turned off, use the
system’s reset button or power-down and up to reset the
system.
SCSI/SMDI-compatible menu is not displayed under Windows 98SE and Windows Me

Verify proper SCSI termination and check for multiple devices on the SCSI chain using the same SCSI ID.
If this fails to solve the problem, Adaptec SCSI card users may need to update the system’s mini-port drivers.
Adaptec has a series of updated mini-port drivers available for Windows 98SE and Windows Me on the
Web.
After you download the file, you must create a temporary directory or folder on the system and run the
WIN95MPD.EXE program. Follow the directions in the readme.txt file to update the drivers for the Adaptec
SCSI card.

Looping

16
Sound Forge® software is an excellent tool for creating loops and provides the perfect compliment to Sony
Media Software’s revolutionary ACID® line of loop-based music creation tools.
Creating loop regions in files is useful only when you intend to transfer the files to a hardware sampler that
supports the loop regions.

Loops
A loop is a sample or region in an audio file that is repeated during playback. Samples are finite and
frequently very short in length. Therefore, they must be repeated (or looped) to create longer or sustaining
sounds.
Note: Loops can also be used to repeat entire sections of

music, although the playlist is better suited to this purpose.

Sustaining and release loops
A sound envelope contains four elements: attack, decay, sustain, and release.
Attack
Decay

Sustain

Release

Typically, the sustain portion of the envelope is looped to lengthen the duration of a sound. This is referred
to as the sustaining loop.
While sustaining loops are useful, it is frequently necessary to create a second loop, taken from later in the
envelope. This allows you to reproduce longer, more complex sounds, such as a piano chord struck with the
sustain pedal depressed. This second type of loop is referred to as the release loop.

Looping techniques
Depending upon the source material, creating a natural-sounding loop can be a difficult task. Many factors
beyond your control may produce distracting pops and glitches, thereby calling unwanted attention to the
loop. Although looping skill is largely the product of practice and experimentation, there are some
guidelines to consider.

Match endpoint amplitudes
This feature is available only in the full version of Sound Forge software.
One of the easiest ways to minimize the occurrence of glitches when creating loops is to select loop
endpoints that have an amplitude of zero. These points are known as zero-crossings. For more information, see
Finding zero-crossings on page 257.

Match endpoint waveform slope
This feature is available only in the full version of Sound Forge software.
Another technique for reducing loop glitches is to avoid matching loop endpoints where the waveform slope
does not match. If the waveform slope changes drastically, a pop plays when the sample is looped.

Non-matching slope

Matching slope

Note: The data windows pictured above display the Loop
Tuner in the bottom half of the window. For more
information on the Loop Tuner, please see page 256.

LOOPING

CHP. 16

255

Match endpoint sound levels
This feature is available only in the full version of Sound Forge software.
The overall amplitude (or loudness) approaching the loop’s endpoints should be as similar as possible to
prevent distracting glitches. Unfortunately, it is frequently difficult to avoid this problem, particularly with
rapidly decaying source material. For more information, see Viewing loop amplitude on page 257.

Non-matching amplitude

Matching amplitude

Avoid very short loops
If the loop is shorter than ~50 ms (1/20 Hz), the pitch of the loop may not equal the sample pitch. Pitchtuning a loop is accomplished by creating short loops with a length equal to 1/frequency. For example, a
sample of pitch 440 Hz corresponds to A5 on the keyboard, meaning the loop can be pitch-tuned 2.27 ms.
However, pitched loops do not sound like the original sample.

CHP. 16

LOOPING

256

Editing loops
This feature is available only in the full version of Sound Forge software.
The loop you initially create in any situation is rarely perfect. Frequently, loops require some degree of
editing before they are usable.

Editing a loop without the Loop Tuner
Once you create a loop, you can quickly edit its beginning and end (and subsequently its length) by dragging
the markers to a new location. However, this method frequently does not provide the control required to
create seamless loops. In this case, you should edit the loop using the Loop Tuner.

Editing a loop with the Loop Tuner
The Loop Tuner allows you to precisely edit loop points in order to prevent distracting audio glitches. This is
accomplished by greatly magnifying the waveform and displaying the loop tags in relation to one another.
The left side of the Loop Tuner window displays the end of the loop, while the right side displays the start of
the loop. This arrangement allows you to fine-tune loops by viewing a graphical representation of the
junction between the end and the start of a loop.
In addition, the Loop Tuner contains several tools designed to assist you in creating professional-sounding
loops.
Displaying the Loop Tuner
1. Open the Loop.pca file. A sustaining loop appears in the data window.
2. From the View menu, choose Loop Tuner. The Loop Tuner appears at the bottom of the data window and

displays the waveform of the file’s loop.

Playing loops using the Loop Tuner

The Loop Tuner contains three playback buttons: Play Pre-Loop, Play Loop, and Play Post-Loop.
Play Pre-Loop: Starts playback of a file
from its beginning and stop playback at
the loop start tag.

Play Post-Loop: Starts playback immediately
following the loop end point and continue
through the end of the file.

Plays Loop: Starts playback of the looped
region. The number of times the loop
plays is dependent upon the Loop count
value in the Edit Sample dialog. Use this
button to audition the loop for pops and
glitches. For more information, see
Creating a sustaining loop on page 252.

Tip: You can use the Play as Sample button

in the
playbar to audition the entire sample with configured loops.
Switching between the sustain and release loops

When working with a file that contains sustain and release loops, you can quickly toggle between the loops

Viewing loop amplitude

The sample amplitude at the loop’s start and end points appears in the lower-right corner of the Loop Tuner.
End Loop Amplitude

Start Loop Amplitude

Although it is dependent upon the specific waveform, a good rule of thumb is that the closer these two
amplitude values are, the more natural the resulting loop sounds.
Finding zero-crossings

The Loop Tuner’s zero-crossing finders are used to locate zero-crossings adjacent to the current loop tag
location.

Loop End Zero-Crossing Right
Loop End Zero-Crossing Left

Loop Start Zero-Crossing Right
Loop Start Zero-Crossing Left

The Loop Tuner contains two zero-crossing finders for each of the loop points.
• The left button in each pair locates the zero-crossing to the left of the current location.
• The right button in each pair locates the zero-crossing to the right of the current location.
To use the finders, click the desired button. By experimenting with different locations and repositioning the
start and end points, you can create seamless loops. You can also configure the zero-crossing finders to locate
positive slope crossings, negative slope crossings, or all zero-crossings.

Configuring the zero-crossing finders
1. From the Options menu, choose Preferences. The Preferences dialog is displayed.
2. Click the Editing tab.
3. From the Snap to zero-crossing slope drop-down list, choose the desired slope and click OK.
Fine-tuning loop points

You can use the Loop Tuner to fine-tune loop points in three ways:
• To move loop points by small amounts, use the Loop Start Position and Loop End Position arrow spinners.
Clicking the up or down arrow increments the loop point by one sample.
• To move loop points by larger amounts, use the mouse to drag the spinner up or down.
• To move loop points by very large amounts, use the mouse to drag the ruler at the top of the Loop Start or
Loop End display.
Click the arrow spinners to
move by one sample

Drag the ruler to move
by large amounts

Locking loop length

The Lock Loop Length button
allows you to freely move the start and end points of a loop without altering
its length. When the button is selected, any editing that moves a loop point affects both loop points, thereby
keeping the loop length constant.
Clicking the Lock Loop Length button a second time turns this feature off and allows loop points to be edited
independently with no regard for the loop’s original length.
Note: The Lock Loop Length button has the same function as

the Lock Loop/Region Length command in the Options
menu.

Crossfading loops
This feature is available only in the full version of Sound Forge software.
You can use the Crossfade Loop tool to loop audio from difficult source material. It allows you to crossfade
the end of a loop with the beginning of the loop in order to create a smoother, more natural-sounding
transition. In addition, you can configure the Crossfade Loop tool to crossfade the beginning of the audio
loop with the beginning of the post-loop audio on the loop’s final pass. This smooths the occasionally
awkward transition from looped to non-looped audio.

Using the Crossfade Loop tool
1. Open the Loop.pca file. A sustaining loop appears in the data window.
2. From the Tools menu, choose Crossfade Loop. The Crossfade Loop dialog is displayed.
3. Drag the Loop slider to configure the percentage of the loop to be crossfaded.

30% loop crossfade

80% loop crossfade

4. If desired, select the Post-Loop check box and drag the slider to configure the percentage of the loop to be

crossfaded into the post-loop audio.

20% post-loop crossfade

90% post-loop crossfade

5. From the Preview mode drop-down list, specify how the Preview button operates: Loop the Loop, Play Loop
through Post-Loop,

or Play as One Shot.

6. Preview and tune the crossfade until you cannot detect the loop transitions.
7. Click OK.

Creating loops for ACID software
The Sound Forge application is an excellent tool for creating and editing loops to be imported into any of
the ACID family of products. You can create four different types of files for ACID use:

Creating an ACID one-shot file
One-shots are files that do not stretch with tempo or change pitch to match the key of the ACID project.
This behavior makes one-shots particularly suited for audio such as cymbal crashes, sound effects, and short
vocal lines.
1. Open the Voiceover.pca file.
2. Create a selection containing the “Wow” and drag it to the workspace. A new data window is created

containing the “Wow” audio data.
3. From the Special menu, choose Edit ACID Properties. The Edit ACID Properties dialog is displayed.
4. Select the One-Shot radio button and click OK.
5. From the File menu, choose Save As and save the file with a descriptive name.

Creating an ACID loop file
Loops are musical building blocks and are by far the most common type of file used in the ACID application.
Loops stretch with an ACID project’s tempo and can be configured to change pitch. When creating Sound
Forge files for use in ACID software, the Edit ACID Properties dialog defaults to the loop setting.
1. Open the Voiceover.pca file.
2. Create a selection containing the “And easier” and drag it to the workspace. A new data window is

created containing the “And easier” audio data.
3. From the Special menu, choose Edit ACID Properties. The Edit ACID Properties dialog is displayed.

Creating an ACID 2.0 disk-based file
ACID 2.0 disk-based files can stretch to comply with an ACID project’s tempo, but require that you specify
the file’s original tempo upon configuration. If the original tempo is not specified in the Edit ACID
Properties dialog, no stretching occurs.
While ACID 2.0 disk-based files can change tempo, they cannot change pitch. Disk-based files are typically
used in ACID 2.0 software for extended vocal tracks or other long audio files that do not loop.
1. Open the Voiceover.pca file and select the entire waveform.
2. From the Special menu, choose Edit ACID Properties. The Edit ACID Properties dialog is displayed.
3. Select the ACID 2.0 Disk-Based radio button. The Tempo check box activates.

4. If the file should stretch to match the ACID 2.0 project’s tempo, select the Tempo check box. The Tempo

box activates.
5. Specify the file’s original tempo (60-240 bpm) in the Tempo box and click OK. For more information, see

Setting loop tempo on page 265.
6. From the File menu, choose Save As and save the file with a descriptive name.

Creating an ACID beatmapped file
ACID beatmapped files can change tempo and pitch to match an ACID project. You must specify the file’s
original tempo and root note for transposing upon configuration. If you do not specify these values, no tempo
or key changes occur. Beatmapped files are typically used in ACID software version 3.0 or later for extended
vocal tracks or other long audio files that do not loop.
1. Open the Voiceover.pca file and select the entire waveform.
2. From the Special menu, choose Edit ACID Properties. The Edit ACID Properties dialog is displayed.
3. Select the ACID Beatmapped radio button. Complete the information for an ACID beatmapped file:

• Select a value from the Root note for transposing drop-down list so that the ACID application can
transpose the file to match the project key. Select Don’t transpose from this list to keep the key from
being changed.
• Specify the file’s original tempo (40-300 bpm) in the Tempo box so that the ACID application can
stretch the file to match the project tempo. For more information, see Setting loop tempo on page 265.
• Enter a value in the Downbeat offset (samples) box to indicate the location of the first downbeat.

Using Spectrum
Analysis

This chapter introduces you to the concept of frequency and describes the Sound Forge® Spectrum
Analysis. Spectrum Analysis allows you to examine audio frequencies and overtones using either spectrum
graphs or sonograms.
Spectrum Analysis is available only in the full version of Sound Forge software.

Working in the frequency domain
Unlike the waveform display, which represents audio in the time domain (amplitude vs. time), Spectrum
Analysis allows you to examine audio recordings in the frequency domain.
Consider the following graphic, which depicts the same audio event as a waveform and as a spectrum graph.

Waveform display

Spectrum graph

Data displayed in the frequency domain (whether in the form of a spectrum graph or sonogram) depicts the
amplitudes and frequencies of sine waves that, if mixed, would sound much like the original audio. Since it is
relatively easy to remember what a sine wave sounds like at a specific frequency, it is possible to imagine
what simple waveforms sound like by examining their spectrum.
Learning to “read” the frequency components of a sound in conjunction with their corresponding amplitudes
makes it possible to determine the fundamental frequency of a sound, as well as its overtones. Similarly, you
can identify unwanted noise, thereby allowing filtering to be applied where needed.

CHP. 18

USING SPECTRUM ANALYSIS

276

Fast Fourier Transform
A Fourier transform is computationally intensive and for this reason it is common to use a technique called a
Fast Fourier Transform (FFT) to perform spectral analysis. The FFT utilizes mathematical shortcuts to reduce
the processing time at the expense of putting limitations on the analysis size.
The analysis size, also referred to as the FFT size, indicates the number of samples from the audio signal used
in analysis and also determines the number of discrete frequency bands. When a large number of frequency
bands are used, the bands have a smaller bandwidth and this provides for more accurate frequency readings.
However, since complex sounds have a rapidly changing spectrum, a large analysis size can blur the timechanging frequencies of a sound. For example, when performing FFT analysis of an audio file sampled at
44,100 Hz using an analysis size of 4096, almost 100 milliseconds (44,100/4096) of sound are analyzed. If the
sound is not constant for those 100 milliseconds, it is impossible to focus on the instantaneous spectrum at
smaller time intervals. This is the trade-off between time resolution and frequency resolution encountered
when analyzing audio signals.
Spectrum Analysis allows you to perform precise FFT analysis and displays the resulting data in two graphical
formats: the Spectrum Graph allows real-time monitoring of playback or input, while the Sonogram displays
a playback cursor for real-time preview. Both formats make it easy to navigate data and read audio frequency
and position.

Using a spectrum graph
In the spectrum graph, the horizontal axis represents frequency in Hertz (Hz), while the vertical axis
represents amplitude in decibels (dB).

Displaying a spectrum graph
1. Open an audio file.
2. Select the portion of the waveform you want to analyze. The sound or note you want to analyze should be

in the center of the highlighted area.
3. From the View menu, choose Spectrum Analysis. The Spectrum Analysis window is displayed.

4. Use the toolbar at the top of the window to set your display options.
Tip: You can also click the Settings button

in the
Spectrum Analysis window to set additional options.
The spectrum graph displays the amplitude (in dB) of each frequency component from 0 Hz (DC) to the
Nyquist frequency.
Tip: You can continue to make selections in the audio file

with the Spectrum Analysis window open (just move the
cursor or make selections as you normally would in the Sound
Forge application). Click the Refresh button in the Spectrum
Analysis toolbar to update the display. If no selection is
made, analysis is performed on the samples immediately
following the cursor position.

Using a sonogram
The sonogram is another way of displaying spectral data variations over time. In a sonogram, the horizontal
axis represents time, and the vertical axis represents frequency.
Sonogram

The amplitude of each frequency component in the sonogram is represented by the color intensity of each
point in the graph. This method of displaying spectral information is useful for identifying distinctive
spectral patterns created from sounds such as speech, musical instruments, and ambient noise.

Displaying a sonogram
1. Open an audio file and select the portion of audio you want to analyze. The sound or note you want to

analyze should be in the center of the highlighted area.
2. From the View menu, choose Spectrum Analysis. The Spectrum Analysis dialog is displayed.
3. Click the Sonogram button

to display your data as a sonogram.

4. Use the toolbar at the top of the window to set your other display options.
Tip: You can also click the Settings button

Tuning a sonogram
It is frequently necessary to experiment with the control parameters in the Spectrum Settings dialog to
produce the best possible sonogram. For more information, see Adjusting Spectrum Analysis settings on page 286.
Improving the graph’s contrast

To improve the contrast of the sonogram, decrease the frequency and amplitude ranges as much as possible.
Smoothing the graph’s display

If the graph appears too pixelated, raise the Set sonogram resolution value to 200.
Improving the frequency resolution

For greater frequency resolution, choose a higher value from the FFT size drop-down list.
Reducing the processing time

To reduce processing time, decrease the Set sonogram resolution value and/or choose a lower value from the
FFT size drop-down list.
Adjusting color intensity

Adjust the sonogram’s color intensity using the Color slider
located directly beneath the sonogram. Notice that the
bottom pane of the dialog depicts the color scale in dB.

Adjusting Spectrum Analysis settings
From the Spectrum Analysis toolbar, click the Settings button
to display the Spectrum Settings dialog.
The following sections explain the role of each control in audio spectrum analysis.

FFT size

Choose a value from the FFT size drop-down list to determine the size (in samples) of the analysis window
and number of discrete frequencies analyzed. Higher FFT size values produce higher frequency resolution at
the expense of lower time resolution and slower processing.
FFT overlap

The value in the FFT overlap box determines the amount of overlap between FFT analysis windows. Lower
values decrease the number of distinct analysis functions performed, which also decreases processing time.
Higher values provide more analysis, but result in slower processing.
Smoothing window

Choose a setting from the Smoothing window drop-down list to determine the window function applied to the
input data prior to analysis. This option influences the sharpness of peaks in an FFT graph and the leakage
into neighboring frequencies.
• Choose Rectangle to apply no window. This results in a very sharp peak, but high leakage.
• Choose Triangular (also referred to as a Bartlett or Parzen window) to apply a window that results in less
leakage than the rectangle window.
• Hamming, Hanning, and Blackman windows are commonly used in audio applications.
• Choose Blackman-Harris to obtain the least sideband leakage of the six options. The major drawback of
Blackman-Harris is rounded graph peaks.
Slices displayed

The Slices displayed value determines the number of FFT slices created for the selection. When displaying
multiple slices in the spectrum graph, slices are displayed chronologically forward or backward based on
whether you have the Forward or Backward radio button selected.

USING SPECTRUM ANALYSIS

CHP. 18

287

Set sonogram resolution

The Set sonogram resolution value determines the number of FFT samplings used in a sonogram. This keeps
the processing time and graph resolution constant. Increasing this value increases the horizontal graph
resolution, but requires more processing time.
When this check box is cleared, the resolution value is determined by the length of the selection and the FFT
overlap value.

Display range
Note: These options are available in Normal display only.

Select the Both, Left, or Right radio button to choose which graph you want to edit.
If you are analyzing a stereo file, select the Sync Graphs check box to synchronize both displays in a stereo file
so you can view the same region of the FFT in both channels.
Select the Logarithmic graphing check box to display the X-axis in logarithmic mode instead of linear mode.
This results in more graph area being devoted to lower frequencies.
Frequency minimum
Determines the lowest frequency displayed in a graph when you select Zoom to Range.
Frequency maximum
Determines the highest frequency displayed in a graph when you select Zoom to Range.
Ceiling
Determines the highest amplitude level displayed in a graph when you select Zoom to Range.
Floor
Determines the lowest amplitude level displayed in a graph when you select Zoom to Range.
Hold peaks during monitoring

Selecting this check box results in the highest value of each frequency being indicated on the spectrum
graph with a small horizontal line. The length of time (in seconds) that the peak is held is determined by the
value entered in the edit box.
Maintain last monitored view

Selecting this check box “freezes” the appearance of the spectrum graph when playback stops. Clearing this
check box results in the graph resetting to the cursor position when playback stops.

Description

Output

Choose a MIDI device from the drop-down list to specify the MIDI output device for
synchronization when Generate MIDI Timecode is enabled.

Input

Choose a MIDI device from the drop-down list to specify the MIDI input device for synchronization
and triggering when Trigger from MIDI Timecode is enabled.
This is the device through which Sound Forge will receive all MIDI triggering and synchronization
input, including SMPTE/MTC, MIDI triggers, and Regions/Playlist triggers.
When this check box is selected, Sound Forge software will not allow recording beyond the
specified end time. This ensures that your record length is exact regardless of any inaccurate
timecode.

Bound record time on SMPTE
generation
Use internal timer for SMPTE
generation

Select this check box if you want to use the internal timer for SMPTE generation rather than
position values reported by the sound card driver. Since many sound cards do not report their
position accurately, it is usually better to use the internal timer for SMPTE generation.
Choose a value from the Internal timer resolution drop-down list to specify the internal timer
accuracy used for generating SMPTE. Low values produce more accurate SMPTE generation, but
may also decrease system performance.

Use free-wheel for SMPTE loss

Select this check box to stop playback if the incoming MIDI timecode signal stops. When this
check box is not selected, Sound Forge playback will continue until the user stops playback manually.
In the Free-wheel time box, specify the amount of time that Sound Forge playback will continue
after the incoming MIDI timecode signal stops. If timecode starts again during this time, playback will continue.
In the Free-wheel slack box, specify how fast the software should expect timecode updates
before going into Free-wheel mode. If you have a fast computer, this value can be set to a lower
value if you want to stop playback immediately when timecode is interrupted.

Enable SMPTE playback offset

Select this check box to specify an offset that will be added to the time displayed in the Sound
Forge play counter. For example, if you want to generate MIDI timecode starting at 01:00:00:00,
instead of inserting 1 hour of silence at the beginning of your sound file, you can specify that
amount in this box.
When using Record Sync, you’ll often want to set this value to the Enable MTC/SMPTE Input
Synchronization Start time. The Sound Forge ruler and play counter will not display this offset.

useful when listening to the difference between the original sound and the sound after an effect
or process has been applied.

This option is most useful when using a fast computer, limiting preview times, and not using
processor-intensive effects.
Note: You can temporarily suspend Reactive Previewing by holding down the Shift key while
making parameter changes.

Audio event locator:
Pre-roll/Post-roll

Use the Pre-roll and Loop time settings to control how the audio event locator plays audio:
• In the Pre-roll box, specify the amount of data played prior to the cursor position.
• In the Loop time box, specify the amount of time that will loop when you stop the
cursor while clicking and dragging in the overview bar.
To use the audio event locator, click the overview bar and drag the mouse. Similar to a scrub
control, playback follows mouse movement and loops around the cursor position when the
mouse is still. Playback stops when the mouse button is released.

Description

Default frames per second

The default frame rate used to calculate frame values.

Default beats per measure

Frame values are useful when trying to synchronize sound with animation. Most animation players specify a playback frame rate at which video frames are shown to the user. If you are using
an animation that has a frame rate of 15.0 frames per second, you would set the frame rate to
15.0. When status values are displayed, they will be shown in values of frames. This allows you to
find the frame to which a given point in the sound file corresponds.

This feature is available only in the full version of Sound Forge software.
0 VU (+4 dBu) corresponds to X
dB FS

Choose a setting from the drop-down list or type a value in the box to calibrate the VU/PPM
meters to their associated levels on the peak meters.
VU meters display sound in dB VU, where 0 VU is a reference level, and there is headroom above
0 VU. The Sound Forge peak meters display peaks in dB FS (decibels relative to full scale).
In digital audio, there is no headroom above 0 dB FS. Choosing a setting from this drop-down list
subtracts a nominal dB value from the VU meters so that a signal displayed on the VU meters
remains slightly below 0 dB on the peak meters.

This feature is available only in the full version of Sound Forge software.
VU meter integration time

Type a value in the box to set the amount of data surrounding the cursor that will be used to calculate levels in the VU meters.

Playback Buffering (seconds)

Specifies the total amount of buffering that is used during playback.
The larger the number, the more buffering is performed during playback. This value must be as
low as possible without gapping. To set it, start at .25 and play back a typical song. Move some
of the track faders. If the playback gaps, try increasing this slider in small increments until the
gapping goes away. As you increase this slider, the RAM meter at the bottom of the ACID window will indicate more RAM usage. You need to strike a balance between RAM usage and playback buffering.
If you simply cannot get playback to be free of gapping, you need to either decrease the number
of tracks you are trying to play simultaneously, install more RAM in your computer so you can
increase buffering, buy a faster access hard drive, or minimize the number of audio plug-ins you
are trying to use simultaneously.

This list contains all of the audio devices that are installed in your computer. Select a device from the
list to set the options below for that device.
When this check box is selected, the software will attempt to compensate for inaccurate devices by
interpolating the playback or recording position. If you notice that your playback cursor is offset from
what you are hearing, enable this option for the playback device.
If the position of playback or recording does not match what you hear after you enable Interpolate
position, you can attempt to compensate using the Position bias slider.

Buffer size

Moving this slider will offset the position forward or backward to compensate for the inaccuracies of
the device.
When this check box is selected, the software will not create buffers prior to starting playback. Some
devices do not behave properly if this check box is cleared.
If your audio stutters when you start playback try selecting this check box.
Drag the slider to set the number of audio buffers that will be used. Adjusting this setting can decrease
gapping or help you synchronize the input and output.
Choose a setting from the drop-down list to indicate the buffer size you want to use. Choose MME to
use the Playback buffering setting on the Audio tab in the Preferences dialog.
For example, if you choose MME from the Buffer size drop-down, set the Audio buffers slider to 5, and
set Playback buffering to 0.35 seconds, five 0.07-second buffers are created.

Priority

If you choose 1024 from the Buffer size drop-down and set the Audio buffers slider to 5, five 1024byte buffers are created.
Choose a setting from the drop-down list to set the priority that is assigned to your audio buffers.
Increasing the buffers' priority can help you attain smoother playback, but it can also adversely affect

• Blend Fields: Maintains the data in the two fields by blending them together. This
method can produce a smooth, motion-blurred image.
• Interpolate: Deletes one field and uses the remaining field to interpolate the deleted
lines. This produces sharper images than Blend Fields but can introduce jagged
motion or stair-stepping artifacts.
Select this check box if you want to interpolate video frames when you render to a frame rate
that is greater than the source file's frame rate.

Microsoft Audio
Compression
Manager

The Microsoft Audio Compression Manager (ACM) is a standard interface for audio compression in
Windows. This interface allows applications such as Sound Forge® to use compression algorithms provided
by other companies.
Sound Forge software fully supports audio compression through the ACM. This allows you to use any ACMcompatible compression. Compressed WAV files are transparently opened and all available compression
formats for WAV files are provided in the Save As dialog.
There are two major components to the ACM:
• Audio data compression and decompression
• Transparent playback and recording of non-hardware supported audio files

Audio data compression and decompression
The first component of the ACM allows audio data to be compressed and decompressed. Audio compression
is used to decrease the amount of data required to represent a sound and results in smaller sound files.
However, there are drawbacks to using audio compression on sound files:
• Most audio compression algorithms degrade sound quality. This is referred to as lossy compression because
information contained in the sound is lost when it is compressed. The amount of sound degradation is
dependent upon the algorithm.
• Compressed audio requires more processing time than uncompressed data. The amount of processing time
is dependent on the algorithm as well as the system’s hardware. Typically, opening and saving compressed
files takes longer than uncompressed files.
• Compressed files are not as portable as uncompressed files. To distribute WAV files in a compressed
format, you must verify that the audience can use them. Also, not all audio software can use compressed
WAV files, which may make using other applications with the Sound Forge software difficult.
In Sound Forge software, any compressed WAV file can be opened if a compatible ACM driver is installed. If
no compatible ACM driver is available for a compressed WAV file, you are alerted to the problem.
Saving compressed WAV files is as simple as specifying the compression algorithm in the Format drop-down
list of the Custom Settings dialog. Once a compressed file is saved, updates to the file are automatically saved
using the selected compression algorithm. The compression format can be changed later—or reverted to an
uncompressed format—using the Save As dialog.

APPENDIX B

MICROSOFT AUDIO COMPRESSION MANAGER

316

Transparent playback and recording of non-hardware supported audio files
The second component of the ACM is called the Sound Mapper. It allows playback and recording of audio
data formats that are not directly supported by the sound card. You can select the Sound Mapper as the
Playback and Record devices on the Audio tab of the Preferences dialog. You can perform any additional
configuration of the Sound Mapper from the Windows Control Panel.
The Sound Mapper functions as follows. When faced with a sound file recorded at an unusual sample rate
such as 22,257 Hz and a sound card that supports 22,050 Hz, the sound file normally cannot be played. The
sample rate of the file must be changed to 22,050 Hz before it can be played back, but changing the sample
rate without resampling causes a pitch shift. However, the Sound Mapper plays this file without resampling
by mapping the sound to the best format possible and performing the resampling in real time.
In addition, the Sound Mapper plays compressed sound files, even on sound cards that do not support
compression directly. A file compressed with Microsoft ADPCM or The DSP Group’s TrueSpeech plays on
any sound card without first decompressing the file.
The Sound Mapper can, under the right circumstances, record compressed sound files. Compressing sound
data can be computationally expensive, and the amount of time required is dependent upon the specific
compression algorithm and how it is implemented. Decompressing sound data is typically faster than
compressing the same sound data.
It should be noted, however, that the Sound Forge application does not play and record compressed sound
files directly. Rather,all compression and decompression is performed while opening and saving the files.
This limitation is fairly insignificant, and the compressed sound files are saved using the best possible
quality—something that cannot always be done in real time. Compressed sound files saved with the software
typically sound better than those recorded with audio compression.
After you save uncompressed audio data to a compressed format, you should audition the file. Compression
and decompression are performed during opening and saving; therefore, the compressed file is not accurately
represented until it has been reopened.

SMPTE Timecode

C
The Society of Motion Picture and Television Engineers (SMPTE) timecode may be one of the most
misunderstood concepts among individuals within the music industry. The problem with SMPTE timecode
formats is that they may mean different things to people in the audio and video fields. What follows is a brief
description of each SMPTE timecode format.
Important: When synchronizing audio to video, it is crucial
that the SMPTE timecode format used in the sequencer or
digital audio workstation is the same as the SMPTE timecode
striped onto the video. This guarantees that the SMPTE times
on the video screen and computer monitor synchronize during
playback.

SMPTE 25 EBU (25 fps, Video)
SMPTE 25 EBU timecode runs at 25 fps (frames per second), and matches the frame rate used by European
Broadcasting Union (EBU) television systems.
SMPTE 25 EBU format is used for PAL DV/D1 video projects.

SMPTE Drop Frame (29.97 fps, Video)
SMPTE Drop Frame timecode runs at 29.97 fps, and matches the frame rate used by NTSC television
systems (North America, Japan).
SMPTE Drop Frame format is used for NTSC DV/D1 video projects.
Both SMPTE Drop and SMPTE Non-Drop run at 29.97 fps. In both formats, the actual frames are not
discarded, but they are numbered differently. SMPTE Drop removes certain frame numbers from the
counting system to keep the SMPTE clock from drifting from real (“wall clock”) time. The time is adjusted
forward by two frames on every minute boundary except 0, 10, 20, 30, 40, and 50. For example, when
SMPTE Drop time increments from 00:00:59.29, the next value is 00:01:00.02.

SMPTE Non-Drop Frame (29.97 fps, Video)
SMPTE Non-Drop Frame timecode runs at a rate of 29.97 fps. This leads to a discrepancy between real
(“wall clock”) time and the SMPTE time, because there is no compensation in the counting system as there
is in SMPTE Drop Frame.
SMPTE Non-Drop format is used for NTSC D1 video projects that are recorded on master tapes striped with
Non-Drop timecode.

APPENDIX C

SMPTE TIMECODE

SMPTE 30 (30 fps, Audio)
SMPTE 30 is an audio-only format and runs at exactly 30 fps. SMPTE 30 is commonly used when
synchronizing audio applications such as multitrack recorders or MIDI sequencers. This format is not used
when working with video.

SMPTE Film Sync (24 fps)
The SMPTE Film Sync time format runs at 24 fps (frames per second). This frame rate matches the standard
crystal-sync 16/33 mm film rate of 24 fps.

Using CSOUND,
MTU, IRCAM, BICSF,
and EBICSF Files

Although Sound Forge® software supports a large number of sound file formats directly, it does not support
the CSOUND, MTU, IRCAM, BICSF or EBICSF file types. However, you can use the Sound Forge Raw
File Type capabilities to extract sound data from these file types.

About IRCAM files
The IRCAM or IRCAM-Gross format consists of a 1024-byte header prior to the audio data. This header
contains standard information like the number of channels, sampling rate, and data format, but can also
contain the name of the sample and comments. This format is used by the MTU system and these files are
frequently referred to as MTU files. IRCAM files support two types of data formats: 16-bit linear PCM and
floating point data.

About BICSF and EBICSF files
BICSF and EBICSF files (Berkeley/IRCAM/CARL Sound File or Extended BICSF) are extensions of the
IRCAM format. Instead of using the standard IRCAM header, these files replace the first 28 bytes of the
header with a standard NeXT/Sun header. This allows the IRCAM format to store additional information in
its 1024-byte header, while also allowing the files to be read by software that supports the NeXT/Sun file
format, such as the Sound Forge application.

Opening files
BICSF and EBICSF files
When reading BICSF and EBICSF files, the software identifies them as NeXT/Sun files. This is because the
header of the BICSF file has been modified to allow it to be read as a NeXT/Sun file. These files are read as
long as they are in one of the supported NeXT/Sun data formats.

IRCAM, CSOUND and MTU files
To read these formats, users must import them as Raw data files. This is best accomplished by configuring the
parameters in the Raw File Type dialog and saving them as presets. The Raw File import function allows
these files to be opened providing they are stored in 16-bit linear format. Sound Forge software does not open
floating point format IRCAM files.
Opening an IRCAM file
1. From the File menu, choose Open. The Open dialog appears.
2. Specify Raw File from the Files of type drop-down list.
3. Select an IRCAM file to open and click OK. The Raw File Type dialog appears.

4. Configure the following parameters:

• Specify a sample rate from the Sample rate drop-down list.
• In the Sample type area, select the 16-bit PCM radio button.
• In the Format area, select the Signed radio button.
• Select the appropriate Channels radio button.
• Select the appropriate Byte order radio button.
• Set the Header value to 1024 bytes.
• Set the Trailer value to 0 bytes.
Note: The settings you choose for opening the file — with
the exception of the sample rate — will be used when you
click Save or save the file using the Default Template setting in
the Save As dialog. The sample rate will be determined from
the source file.

Tip: If you do not always use the same settings for reading

raw files, make sure the Keep media files locked check box is
selected on the General tab of the Preferences dialog.
Otherwise, the individual settings will be lost if you have
multiple raw files open and switch away from the Sound
Forge window.
5. Click Save As. The Save Preset dialog is displayed.
6. Enter a name for the preset in the New preset name box and click OK. The preset is saved and the Raw File

Type dialog is displayed.
7. Click OK. The file opens.

Remember that the byte order of files generated by CSOUND is not constant. CSOUND executables for PC
generate files that use Little Endian byte ordering, while CSOUND for other platforms tends to generate
files with Big Endian ordering. In addition, MTU files use Big Endian byte ordering. Sony Media Software
recommends initially trying a file in Big Endian.
Note: You may want to save presets for byte ordering, as
well as mono/stereo, when receiving CSOUND files from a
number of source computers.

Saving files
You cannot save these files in their original format. You must select a Sound Forge-supported file format.
To save files for use with software that supports the BICSF/EBICSF format, use the NeXT/Sun format. This
format does not save the additional information found in BICSF/EBICSF files, but allows the data to be read
as a NeXT/Sun file.
