doing it in-process is a bit more complicated, especially with OpenAL (I think).
This has to be in-App, ON the iPhone itself!
A bit of an OT reply but are you sure that pitch shifting is what you
need here? You could probably get away by transposing (sample rate
converting) the notes which is several orders of magnitude faster than
pitch shifting.
I have been told that this approach sucks badly. like if you simply transpose a singing voice up an octave, it sounds like a chipmunk...
