About Audio in Motion
You can add audio files to your project and use markers and keyframes to sync the audio
with other events in your project. You can import several different types of audio files,
including the audio tracks from QuickTime movie clips. For each mono audio file you add
to a project, Motion creates a single audio track. For each multichannel audio file you
add to a project, Motion creates a single audio track for each channel.
