I have been looking a the AUTimePitchTest sample code. It successfully changes the playback rate parameter in an AUTimePitch audio unit.
When I modify the sample code to change the pitch parameter, it seems to have no effect.
There is an earlier thread on the core audio list with the same issue. Has anyone been able to get this to work? Is this a know bug with the AUTimePitch unit?
thanks,
rob
What values are you using? In the earlier thread he was using the values 0.0 to 20.0. Not much pitch shifting going on there...I'd say try 100.00 and see what's up.
kTimePitchParam_Pitch
The value is in cents, i.e. 1/100ths of a semitone.
Range is -2400.0 to +2400.0 which is down two octaves to up two octaves.
