AUHAL could be used for this.
Even easier though, I think you should just be able to use and
AudioQueue

Hi All,
I'm trying to put together a CoreAudio app that would start
recording from an input, triggered by speech (kind of like those
voice-activated tape recorders.)
The order of ops would be:
1. Open an audio input for recording to a file.
2. Do nothing while detecting silence.
3. Upon detecting non-silence, start recording to said file.
4. Stop recording after x seconds of silence.
Is it possible to construct a CoreAudio app with the standard-issue
AU's shipped with MacOS 10.5.x?
Or do I have to make a custom AU to do this?
Any pointers on where to start or how to go about this would be much
appreciated!
Thanks,
Bob Ingraham
