音频剪辑不会连续循环 [英] Audio Clip won't loop continuously

问题描述

有人能指出正确的方向，为什么这段代码不能连续播放这个音频片段？它播放一次并停止。

Can anyone point me in the right direction as to why this code will not play this audio clip continuously? It plays it once and stops.

final Clip clip = AudioSystem.getClip();
final AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File("Alarm_Police.wav"));
clip.open(inputStream);
clip.loop(Clip.LOOP_CONTINUOUSLY);

推荐答案

如果您正在运行更大的应用程序，这个答案可能是不适用。但是对于仅使用那段代码的简单测试，这可能帮助：

If you are running a bigger application, this answer may not apply. But for a simple test with only that piece of code, this may help:

Clip.loop（）启动它自己的线程，但是线程不会使JVM保持活动状态。因此，为了使其工作，请确保剪辑不是唯一的线程。

Clip.loop() starts it's own thread, but that thread will not keep the JVM alive. So to make it work, make sure the clip is not the only thread.

如果我从这个片段中遗漏Thread.sleep（..），我会遇到与你相同的问题;

If I leave out Thread.sleep(..) from this snippet, I get the same issue as you;

import java.io.File;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

public class Snippet {
    public static void main(String[] args) throws Exception {

        AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File("notify.wav"));
        Clip clip = AudioSystem.getClip();
        clip.open(inputStream);
        clip.loop(Clip.LOOP_CONTINUOUSLY);
        Thread.sleep(10000); // looping as long as this thread is alive
    }
}
