Supported Audio File Formats
You can add audio files in the following formats: AIFF, WAVE, Broadcast WAVE, Sound
Designer II, NeXT, QuickTime (.mov) audio files, and CAF (Apple Core Audio Format).
Compressed formats such as MP3 and AAC (except protected AAC) files are also
supported, although these must be internally decompressed to a linear PCM format.
You can also add the following types of multichannel files: AIFF, WAV, Broadcast WAVE,
QuickTime, and Single Folder Multi-mono AIFF and WAV. 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 formats with higher bit depths or sample rates.
Supported Video File Formats
Soundtrack Pro supports standard QuickTime-compatible file formats. You can import a
QuickTime movie (.mov) file into a Soundtrack Pro project, and you can import an
MPEG-2 (.m2v) file if you have installed the QuickTime MPEG-2 Playback Component.
Video files using NTSC, PAL, HD, and other formats supported by QuickTime can be
imported into Soundtrack Pro. Imported video files can be up to four hours in length.
For more information about importing video files, see Chapter 10, “
Working with Video
in Soundtrack Pro ,” on page 315.
Looping and Non-Looping Files
Soundtrack Pro supports two types of audio files: looping and non-looping files. Most audio
files are non-looping files unless they contain tags for tempo, key, and other information.
Many of the Apple Loops that come with Soundtrack Pro, as well as other tagged audio
files, can be looping files. Looping files may contain music, rhythmic sounds, or other
repeating patterns. You can resize a looping file to fill any amount of time. Looping files
adjust to the project tempo and key, letting you use loops recorded in different keys
and at different tempos in the same project.
