Actually there's a whole lot of information on these two in AudioUnitProperties.h (AudioUnit.framework)
Also, since you mentioned locking the speed of audio files to your reference, there is a DiracAudioPlayer class that comes with the free Dirac LE time stretching project that does file playback by emulating the AudioFilePlayer API while simultaneously being able to change pitch and speed independently in real time.
Not sure if this is useful in your case but here's the link:

Hi,
Is there any documentation or sample code for either of these AU subtypes? I'm working in OS X 10.6.
I have read through AUComponent.h, which pretty much just says they exist.
My application needs to be able to play individual music files locked reasonably accurately to time code or some other stable time reference to generate musical structures (chords, rhythms, melodies) similar to how a sequencer/sampler combination would accomplish this. I have been using audioqueues, but am now moving towards an audiograph based structure.
These sub types sound useful, it would be nice to have an idea of how to link them to audio files, or to buffers extracted from files.
thanks,
rob
