Java剪辑（声音/音频）内存关闭后关闭（） [英] Java Clip (Sound / Audio) Memory Leak after closing with close()

问题描述

以下代码创建一个新的音频片段，播放它，睡眠3秒钟，然后在播放完毕后关闭它。尽管调用了close（），但每次while循环运行时，我都会看到jvm的内存使用量会增加声音片段的大小。

The following code creates a new audio clip, plays it, sleeps for 3 seconds and then closes it when it is finished playing. Despite the call to close(), I am watching the memory usage of the jvm go up by the size of the sound clip every time the while loop is run.

I参与用java编码的游戏，我正在处理声音。每次播放声音时，我都无法使用增加的内存。

I'm participating in a game coded in java, and am handling the sound. I cannot have the memory i'm using increase everytime a sound is played.

我缺少什么？

import java.io.File;
import javax.sound.sampled.*;

public class ClipLeak{

public static void main(String[] args) throws Exception{
    while(true){
        File soundFile = new File("./sound.wav");
        AudioInputStream sound = AudioSystem.getAudioInputStream(soundFile);

        DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat());
        Clip clip = (Clip) AudioSystem.getLine(info);
        clip.open(sound);
                    sound.close();

        clip.addLineListener(new LineListener(){
            public void update(LineEvent event){
                if(event.getType() == LineEvent.Type.STOP){
                    event.getLine().close();
                }
            }
        });

        clip.start();
        Thread.sleep(2000);
    }
}
}

推荐答案

Try this
    import java.io.File;
    import javax.sound.sampled.*;

    public class ClipLeak{

    public static void main(String[] args) throws Exception{
        while(true){
            File soundFile = new File("./sound.wav");
            AudioInputStream sound = AudioSystem.getAudioInputStream(soundFile);

            DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat());
            Clip clip = (Clip) AudioSystem.getLine(info);
            clip.open(sound);


            clip.addLineListener(new LineListener(){
                public void update(LineEvent event){
                    if(event.getType() == LineEvent.Type.STOP){
                        event.getLine().close();
                    }
                }
            });

            clip.start();
            Thread.sleep(2000);
            if (clip.isOpen()) {
             clip.close();
             sound.close();
            }
        }
    }
    }
