如何玩同样的声音与AVAudioPlayer重叠？ [英] How to play the same sound overlapping with AVAudioPlayer?

问题描述

这code起着当按钮被点击的声音，但取消了previous如果再次pssed $ P $。我不希望这种事情发生我想同样的声音重叠时反复pressed。我相信这可能是由于使用相同的AVAudioPlayer，因为我已经看过了互联网上，但我是新来的迅速，想知道如何创建一个新的AVAudioPlayer每次方法运行，因此声音重叠。

  FUNC playSound（音：字符串）{
    //设置声音文件的名称和放大器;延期    让和声= NSURL（fileURLWithPath：NSBundle.mainBundle（）pathForResource（音，ofType：MP3）！）
    做{
        // preperation
        尝试AVAudioSession.sharedInstance（）。setCategory（AVAudioSessionCategoryPlayback）
    }赶上_ {
    }
    做{
        尝试AVAudioSession.sharedInstance（）。SETACTIVE（真）
    }
    赶上_ {
    }
    //播放声音
    VAR错误：NSError？
    做{
        audioPlayer =尝试AVAudioPlayer（contentsOfURL：和声）
    }赶上让ERROR1为NSError {
        错误= ERROR1
    }   audioPlayer。prepareToPlay（）
  audioPlayer.play（）}
 

解决方案

要两个声音同时播放与AVAudioPlayer你只需要使用不同的球员每种声音。

在我的例子中，我声明了两个球员， playerBoom 和 playerCrash 在的viewController了，我中号填充它们拥有完善的通过功能的发挥，然后触发播放一次：

 进口AVFoundation一流的ViewController：UIViewController的{    VAR playerBoom：AVAudioPlayer？
    VAR playerCrash：AVAudioPlayer？    覆盖FUNC viewDidLoad中（）{
        super.viewDidLoad（）        playerBoom = preparePlayerForSound（命名为：Sound1例子）
        playerCrash = preparePlayerForSound（命名为：SOUND2）        playerBoom？prepareToPlay（）
        playerCrash？prepareToPlay（）
        playerBoom？.play（）
        playerCrash？.play（）    }    FUNC preparePlayerForSound（命名声：字符串） -  GT; AVAudioPlayer？ {
        做{
            如果让和声= NSBundle.mainBundle（）pathForResource（音，ofType：MP3）{
                尝试AVAudioSession.sharedInstance（）。setCategory（AVAudioSessionCategoryPlayback）
                尝试AVAudioSession.sharedInstance（）。SETACTIVE（真）
                返回尝试AVAudioPlayer（contentsOfURL：NSURL（fileURLWithPath：和声））
            }其他{
                打印（文件\\（音）.MP3不可用）
            }
        }赶上让误差NSError {
            打印（错误）
        }
        零回报
    }}
 

这工作得很好，但如果你有很多的声音打IMO是不适合的。这对只有几的人一个完全有效的解决方案，但

的这个例子是两种不同的声音，但当然的想法是完全两个同文的声音是一样的。的

This code plays the sound when the button is tapped but cancels the previous if it is pressed again. I do not want this to happen I want the same sound to overlap when repeatedly pressed. I believe it might be due to using the same AVAudioPlayer as I have looked on the internet but I am new to swift and want to know how to create a new AVAudioPlayer everytime the method runs so the sounds overlap.

   func playSound(sound:String){


    // Set the sound file name & extension

    let soundPath = NSURL(fileURLWithPath:NSBundle.mainBundle().pathForResource(sound, ofType: "mp3")!)
    do {
        //Preperation
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    } catch _{
    }
    do {
        try AVAudioSession.sharedInstance().setActive(true)
    }
    catch _ {
    }
    //Play the sound
    var error:NSError?
    do{
        audioPlayer = try AVAudioPlayer(contentsOfURL: soundPath)
    }catch let error1 as NSError {
        error = error1
    }

   audioPlayer.prepareToPlay()
  audioPlayer.play()

}

解决方案

To play two sounds simultaneously with AVAudioPlayer you just have to use a different player for each sound.

In my example I've declared two players, playerBoom and playerCrash, in the Viewcontroller, and I'm populating them with a sound to play via a function, then trigger the play at once:

import AVFoundation

class ViewController: UIViewController {

    var playerBoom:AVAudioPlayer?
    var playerCrash:AVAudioPlayer?

    override func viewDidLoad() {
        super.viewDidLoad()

        playerBoom = preparePlayerForSound(named: "sound1")
        playerCrash = preparePlayerForSound(named: "sound2")

        playerBoom?.prepareToPlay()
        playerCrash?.prepareToPlay()
        playerBoom?.play()
        playerCrash?.play()

    }

    func preparePlayerForSound(named sound: String) -> AVAudioPlayer? {
        do {
            if let soundPath = NSBundle.mainBundle().pathForResource(sound, ofType: "mp3") {
                try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
                try AVAudioSession.sharedInstance().setActive(true)
                return try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: soundPath))
            } else {
                print("The file '\(sound).mp3' is not available")
            }
        } catch let error as NSError {
            print(error)
        }
        return nil
    }

}

It works very well but IMO is not suitable if you have many sounds to play. It's a perfectly valid solution for just a few ones, though.

This example is with two different sounds but of course the idea is exactly the same for two identic sounds.
