How to play audio with different speed?

For example, play a local audio file with double speed or half speed.
I've already checked several Github projects, but none of them supports that. Any idea about how to make it will be appreciated.

Now it is possible to change the speed of sound.

here is my sample code:

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];

you set "enableRate" to YES and you can change it.

player.rate = 2.0 // Whatever speed you want

Assuming you're using AVAudioPlayer. you can change speed by changing the rate.
