Apparently there is a new pitch shifting unit in iOS 5 but I never got it to work. We're using Dirac http://dirac.dspdimension.com in our products. I can highly recommend it.

is kAudioUnitSubType_Varispeed avaible in ios5? I'm a bit confused; is there a way to obtain live pitch shifting using only ios new sdk?

My app should record RemoteIO mic input, shift it and record it on file;
everything is working but shifting; is 3rd party code the only easy way?

Varispeed Unit Parameters

Parameters for the Varispeed unit.

enum {

kVarispeedParam_PlaybackCents

it states "Available in iOS 5.0 and later." but I do get

how to get info about that? is the one I should use?
