Chapter 4 Getting Started with Soundtrack 57

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.

Â 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.

Â 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.

Â 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 keyboard shortcuts, see Appendix B, “Soundtrack

Keyboard Shortcuts,” on page 189.

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 and STAP (Soundtrack Pro Audio Project) files. You

can import audio files with any combination of the following sample rates and bit depths:

Sample Rates

Â Any sample rate from 8 kHz to 192 kHz

Bit Depths

Â 8 bit

Â 16 bit

Â 24 bit

Â 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.
