Play multiple audio files in sequence as one

Question

I'm trying to implement an Audio Player to play multiple files as if they were a single one. However, the initial buffer time should be only the first part's duration, and the other files should be loaded in sequence.

For example:

• File1:
  • Part1 - 0:35s
  • Part2 - 0:47s
  • Part3 - 0:07s

The File1 should be played as if it had 1:29, but we'd only wait (at most) until Part1 is loaded to start playing.

I've had a look at AVAsset, but it doesn't seem to solve the problem. I also thought of implementing it using AVAudioPlayer and doing all the logic myself.

Has anyone had this issue before?

Thanks!

You can use AVQueuePlayer for achieving this. You need to create AVPlayerItem using your files url and then need to initialize the AVQueuePlayer using it's queuePlayerWithItems: method.

AVPlayerItem *firstItem  = [[AVPlayerItem alloc] initWithURL:firstPartURL];
AVPlayerItem *secondItem = [[AVPlayerItem alloc] initWithURL:secondPartURL];
AVPlayerItem *thirdItem  = [[AVPlayerItem alloc] initWithURL:thirdPartURL];    

NSArray *itemsToPlay     = [NSArray arrayWithObjects:firstItem, secondItem, thirdItem, nil];
AVQueuePlayer *qPlayer   = [AVQueuePlayer queuePlayerWithItems:itemsToPlay];

[qPlayer play];
