Controlling Playback Using Keyboard Shortcuts
There are a number of keyboard shortcuts you can use to control playback of your
project. To use keyboard shortcuts, the pointer cannot be in a text field.
 Space bar: Plays back the project from the current playhead position. If the project is
playing, pressing the Space bar sets the playhead back to the point from which the
project started playing. This is equivalent to clicking the Play button.
 Return: Sets the playhead to the beginning of the project. If the playback region is
active, pressing Return sets the playhead to the beginning of the playback region.
This is equivalent to clicking the Go to Beginning button.
 Shift-Return: Sets the playhead to the beginning of the project, and starts playback if
it is stopped. This is equivalent to clicking the Start from Beginning button.
For a complete list of Soundtrack Pro keyboard shortcuts, see Appendix B,
“Soundtrack Pro Keyboard Shortcuts,” on page 279.
Locating and Adding Audio Files
You can locate media files to use in a project using the Media and Effects Manager, or
drag files from the Finder. The Media and Effects Manager gives you three ways to
locate audio files: the Browser, Favorites, and Search tabs. You can also store media files
for a project in the Bin for easy access in a project.
Supported Audio File Formats
You can add AIFF, WAV, MP3, and AAC (except protected AAC) files to a project. You can
also add QuickTime (.mov) audio files. You can import audio files with any combination
of the following sample rates and bit depths:
Sample Rates
 Any sample rate from 8 kHz to 192 kHz
Bit Depths
 8 bit
 16 bit
 24 bit
 32 bit (both integer and floating point)
Note: Files with lower bit depths or sample rates do not have the same playback
quality as do higher-rate formats.
