java的同时播放多个剪辑 [英] Java play multiple Clips simultaneously
问题描述
所以我的应用程序应该我点击面板上的每一次播放WAV文件。但现在的问题是，它会等待第一个完成它扮演的第二个之前。我希望能够让他们同时播放。
So my application should play the WAV file every time I click on the panel. But the problem right now is, it waits for the first one to finish before it plays the second one. I want to be able to have them play simultaneously.
我把视频下载的原因（500）是因为如果我不这样做，那么它不会播放声音在所有：（
The reason I put Thread.sleep(500) is because if I don't, then it won't play the sound at all :(

更新：好了，所以我让他们来打simeutaneously，但我想使线程关闭时，剪辑完成打，而不是让线程等待500ms的
Update: Okay so I got them to play simeutaneously, but I want to make the the thread close when the Clip is done playing, instead of making the thread wait 500ms
我怎么能这样做？
推荐答案
我一直运行多个声音是这样的。我猜javaSound已经运行在另一个线程剪辑我不产生新线程。主营游戏循环可能会继续做自己的东西。应用程序可以注册监听回调或使用干将，看看剪辑做。
I have always run multiple sounds like this. I don't spawn a new thread as I guess javaSound already runs clips in an another threads. Main "game loop" may continue doing its own stuff. App may register listeners for callbacks or use getters to see what clips are doing.
有时候，如果我们要使多媒体或游戏应用的更容易只使用干将。运行gameloop 30-60fps给出了大多数情况下足够的粒度和我们发生了什么，当一个总量控制。这个小testapp播放2 wav文件，首先是运行一次，第二个是3秒，第二循环开始后。
Sometimes if we are to make multimedia or game application its easier to just use getters. Running gameloop 30-60fps gives enough granularity for most cases and we have a total control of what happens and when. This little testapp playbacks two wav files, first is run once, second is started after 3sec, second loops.

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(filename));
Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);
clip.setFramePosition(0);
// values have min/max values, for now don't check for outOfBounds values
FloatControl gainControl = (FloatControl)clip.getControl(FloatControl.Type.MASTER_GAIN);
gainControl.setValue(gain);
if(autostart) clip.start();
return clip;
}
