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