I started playing around with the new AUNewTimePitch in IOS 6. There does not seem to be much documentation. I found the following in AudioUnitParameters.h
I am not sure how to interpret the parameter range comments. For example what does
Any idea what kNewTimePitchParam_Overlap and kNewTimePitchParam_EnablePeakLocking do?
// Parameters for AUNewTimePitch
enum {
// Global, rate, 1/32 -> 32.0, 1.0
kNewTimePitchParam_Rate = 0,
// Global, Cents, -2400 -> 2400, 1.0
kNewTimePitchParam_Pitch = 1,
// Global, generic, 3.0 -> 32.0, 8.0
kNewTimePitchParam_Overlap = 4,
// Global, Boolean, 0->1, 1
kNewTimePitchParam_EnablePeakLocking = 6
};
