AVAudioPlayer rate

Question

So I\'m trying to play a sound file at a different rate in iOS 5.1.1, and am having absolutely no luck. So far I have tried setting the rate of the AVAudioPlayer:

Answer 1

This is how you do it.

rate value is between 0.1f - 2.0f

player = [[AVAudioPlayer alloc]
          initWithContentsOfURL:[NSURL fileURLWithPath:path]
          error:&err];
player.volume = 0.4f;
player.enableRate=YES;
[player prepareToPlay];
[player setNumberOfLoops:0];
player.rate=2.0f;
[player play];
