Nope. For that you need to use AudioUnits; there's a built-in unit that will do
time/pitch shifting.

Basically you'd create an AUGraph that looks like
audio-in ---> pitch-shifter ---> audio-out
CoreAudio is kind of involved :( but there's a bunch of C++ sample code and
utilities in /Developer/Examples/CoreAudio/. If you run into trouble, the
coreaudio-api list is the right place to ask questions.
