Ya, JACK would probably be something you could use. Asterisk has some JACK 
support now. Look at app_jack.c (I've not used JACK before).

Alternatively, in trunk is the dialplan function func_pitchshift.c which can 
manipulate the pitch on a channel. It depends how you're trying to manipulate 
the audio I guess.
