AVAudioPlayer - playing multiple audio files, in sequence

Question

I want to play multiple MP3 files, in sequence (one after the other) , using AVAudioPlayer. I tried it, and it stops after playing the first MP3. However, if I go into debugger, it works fine.. any ideas? I read somewhere AVAudioPlayer plays audio in the background.. how do I prevent it from doing this? Vas

Answer 1

It would help to see your code. Somethings to look at - are you using one AVAudioPlayer per sound?

When you play mp3 files only one can play at a time so any over lap may not give expected results.

Not sure why the debugger would make a difference unless you mean in the simulator too. Maybe the simulator can play multiple mp3 files concurrently (since that is a result of mp3 decoding hardware in the iPhone).

Well more info will help us find a solution so feel free to post som code.

The following code ONLY plays one sound - ignores the other. Im very new to IPHONE sdk - ive scoured the web looking for a working example - Please GURUS of OBJC please help a poor Padawan learner. IPhone SDK 2.2.1

  (void)viewDidLoad {

  path2 = [[NSBundle mainBundle] pathForResource:@"alien" ofType:@"caf"];

  oplayer=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path2] error:NULL];

  oplayer.delegate = self;

  path = [[NSBundle mainBundle] pathForResource:@"Lotus" ofType:@"caf"];

  player=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];

  player.delegate = self;

  [oplayer play];

  [player play];

}

Answer 3

Use one AVAudioPlayer per sound.

You should use one AVAudioPlayer and let it play the next file in the sequence by implementing audioPlayerDidFinishPlaying:successfully:. You could use an array with the filenames, keeping track of your current position with a simple integer that you increment on every audioPlayerDidFinishPlaying..
