Apple Soundtrack Pro 3 - Manual (Page 70)

You can mix a multitrack project using track controls for volume, pan, mute, solo, effects,
and effect parameters. These controls are available both in the Timeline and in channel
strips in the Mixer. You can create additional audio busses for effect sends. You can group
audio track outputs together with submixes. Tracks, busses, and submixes can be exported
to individual audio files, or a mixdown of all the tracks can be exported to a stereo or
multichannel audio file. These exported files can then be imported into Final Cut Pro.
Audio File Projects
Soundtrack Pro allows you to edit individual audio files (sometimes known as waveform
editing) using Soundtrack Pro audio file projects. However, unlike most waveform editing
applications, Soundtrack Pro allows you to edit your audio files nondestructively by
keeping track of the actions you have performed on your audio file. For more information
about Soundtrack Pro audio file projects, see
Working in the File Editor .
You can remove, disable, or reorder past actions at any time or save actions as AppleScript
documents that you can use to batch process other audio files. Actions you can perform
include trimming audio, copying and pasting parts of the waveform, normalizing or
amplifying levels, applying effects, and applying noise, pop, and click reduction.
Soundtrack Pro audio file projects are stored in Mac OS X packages (or bundles). A package
appears to be a single file in the Finder but actually contains a collection of files such as
the original audio file, temporary render files, and the list of actions applied to your audio
file.
Important: So that you benefit from nondestructive editing, the default option for saving
edited audio files is as a Soundtrack Pro audio file project. Soundtrack Pro usually does
this automatically any time you apply any command or effect from the Process menu to
a clip in the Timeline. For more information on when Soundtrack Pro automatically creates
audio file projects, see
How Source Audio File Editing Works in a Multitrack Project .
