Thanks guys. My app would need to
support other VOIP-type apps, too, so I'm thinking a Soundflower-like solution
is the only solution here.

In the pitch detection case, there's no need to intercept audio
input
because multiple applications can have the same input device
open and
get the same data. You do not need AudioUnit code to
open the audio
input and get data.
In the Skype pre-process
case, you would need to alter the data for
another application, so
you need to point Skype to your audio data
instead of the usual
input. I'm not sure whether Soundflower has the
same features
for input as it does for output. Perhaps the easiest
approach
would be to write the Skype developers and ask them to
support
AudioUnit plugins on the input audio. That way you could
process the audio without writing any code (assuming that all the
processing you need is available in existing AUs).

I am looking to avoid Audio Units, since I'd
like to use my code on
both the Mac and iPhone.

Somewhat of a novice question here - is it possible
to catch and
process the audio from, say, the internal mic before it
gets passed to
the application space, without resorting to something
like Soundflower
or a custom kernel driver? Is it even
possible via a kernel driver?
Specifically, I'd like to write
an application (user-land driver,
AudioUnit, or whatever) that can
pre-process audio-in before it's
provided to another application (eg
Skype).
