Apple Soundtrack Pro 3 - Manual (Page 71)

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.
Soundtrack Pro supports audio files with any sample rate between 8 kHz and 192 kHz
and any of the following bit depths: 8, 16, 24, 32, and 32-bit floating point. Up to 24 audio
channels are supported in a single file.
When you set a sample rate and play a file, Soundtrack Pro plays at the nearest sample
rate your hardware can support.
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.
You can also open and add the following types of multichannel files:
• AIFF
• WAVE
• Broadcast WAVE
• QuickTime
• Single Folder Multi-mono AIFF and WAV
Supported Video File Formats
Soundtrack Pro supports the following file formats:
• 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
For more information about importing video files, see Working with Video in
Soundtrack Pro .
About 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.
