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 had the same question (to process audio realtime for pitch

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).
