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