Well Real-Time (but I think it's not possible on Mac OS X) or Soft-
RealTime (like SRT on Linux).
Mac OS X has support for such things (THREAD_TIME_CONSTRAINT_POLICY)
and the Mac OS X schedular can provide one of the more consistent low
latency scheduling available on any desktop grade operating system
that exist today. For example it is one of the reason the Core Audio
can provide audio processing that you can use in a live (on stage)
situations.
With that said do you really need to go to this level of things? What
is the sampling frequency of the capture device you are interfacing
with?
