Play multiple Audio Files with AVPlayer

问题:

I'm trying to play multiple sounds at the same time.

The approach initially I've taken was to create several players , but it seems wrong one.

What's the best way to play several audio files at the same time.

Is it through making them AVAssets, but in this case how would I stop and play them whenever I want.

Really appreciate your help.

The reason I need AVPlayer is to fetch sounds from the iPod Library.

I finally got an answer from TechSupport of Apple Dev Team and it seems I'm on the right track when I decided to use several AVPlayer.

For every sound you want to make make a new AVPlayer.

NSURL *url = [NSURL URLWithString:pathToYourFile];
AVPlayer *audioPlayer = [[AVPlayer alloc] initWithURL:url];
[audioPlayer play];

I have never answered a question here and I don't know in anyone is still waiting for an answer to this but heres my take... Try this and it should work, I am currently using it to play 12 plus simultaneous audio samples. I apologize if I am doing something newbish..

You press a button and you run this code...

But first you need to:

1. Need to import AVFoundation to project and #import into .h file as well then we can play sound with this.
2. Need to put "AVAudioPlayer *myAudio;" without quotation marks of course somewhere on top (usually on top of viewDidLoad).

Then just...

-(IBAction)playButtonPressed:(id)sender {

    NSURL *yourMusicFile;
    yourMusicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"your_Song_Name" ofType:@"mp3"]];

    myAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
    [myAudio play];
    NSLog(@"Button -playButtonPressed- has been pressed!");
}

Well, my solution comes out of experience. I can quickly cook up a project if needed. But also, it requires the use of an MoMu API at Stanford. It involves creating WvIn and WvOut objects for reading the files. The audio samples of these objects simply need to be fed to the output buffer to play the files simultaneously. Although the API uses AVFoundation, there is no explicit use of AVFoundation in this project.
