I'm making an app where I gotta record sound through microphone, change its pitch, save it in Documents Directory and play it.
I have accomplished the recording and playing part successfully via
AVAudioPlayer. But I'm unable to change the pitch of the recorder sound :(
Searched a lot all over StackOverlow and Google, but all methods aren't working. DIRAC is not available now I guess, SoundTouch integration is going over my head, other solutions are in Objectice-C++ which I don't understand.
OpenAL, but it only allows to play the changed pitch sound, not save it.
Please tell me if it's possible using Objective-C, or any other example/tutorial.
