This makes a _lot_ more sense. I was having a hard time believing that a
latency of 300 mics (15 samples at 48kHz) could cause you to drop audio. As
it is, you must have buffer sizes set very small, or a very high sample rate
for 1.2 ms to cause a problem; that still only 60 sample frames, right?
I would be very interested to hear whether you experience these issues with
using the mach semaphores. Also, I suspect that there may be some issues
you are dealing with that are unique to the sinp (Sound Input) side of
things. It would be further interesting to know what happens if you sat
directly atop the CoreAudio AudioDevice API, instead of going through the
Sound Manager.
Of course, it is easy for me to suggest a code re-architecture, since I
don't have to do the actual work on your project... ;-)
