Looping Sound Has Clicking Noise At The End Of The Loop

I have the music looped and everything is working as it should, but for some reason the looping background music has a clicking noise and a stutter at the end of the loop. Has anyone else had this issue and if so how did you rectify the situation?

I used Logic Studio 8 for the sound file with no open mics, So I know it's not the sound file.

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/theeye3.caf", [[NSBundle mainBundle] resourcePath]]];

audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
audioPlayer.numberOfLoops = -1;
[audioPlayer play]

Thanks.

Yes, this is usually because your sound file is compressed, and thereby not having the ending point amplitudes at the exact same level. I have the same problem in a game, my solution was to add a sound effect (which is parts of the looping menu music anyway) to play 0.3 secs before the looping. It actually covers the problem.

Have you tried looping it in an audio editor to make sure that the problem is not with the sample itself? If the sample doesn't start and end on a zero point you may get clicks.
