How can I change the Music Note(audio file) to right pitch?
file - C3.wav
I wanna play the note C3 to D3. And to Higher or lower. (I plan to make a music keyboard by The Amazing)
AudioUnitSetParameter(_pitch.audioUnit, kAudioUnitScope_Global, 0, kVarispeedParam_PlaybackRate, 1.40, 0);
How can I change the pitch to right note?
