Question

Windows 7 使用NetBeans

所以我使用这个页面编写了这个非常酷的声音引擎 http://www.docjar.org/docs/api/sun/audio/AudioPlayer.html 音频播放器...... 现在我做了循环和一切一切正常：D 但是当我播放2000赫兹或更低的声音时，一切正常但是像任何高于3000-4000的那样它会给我这个错误

    10/08/2011 01:53:37 org.game.engine.SoundEngine loop
    SEVERE: null
    java.io.IOException: could not create AudioData object
at sun.audio.AudioStream.getData(AudioStream.java:110)
at org.game.engine.SoundEngine.loop(SoundEngine.java:61)
at org.enginetest.EngineTest.main(EngineTest.java:30)

现在我100％肯定它不是文件它自己因为我尝试使用多个声音，赫兹高于4000，它仍然无法正常工作。现在我知道它只接受WAV所以我只给它wav文件。我不知道为什么这样做！ BTW !!!!!重要!!!! 它不适用于高于4000 Hz的声音只有当我尝试使用ContinuousAudioDataStream循环声音时才会这样做如果我玩它，它完美地工作... 我该如何解决这个Hz限制问题？也许你可以给我一个有效的代码......

这是我正在使用的两个声音文件工作声音： http://www.mediafire.com/?kyqlr6dah71q62b 不工作的声音： http://www.mediafire.com/?72whdk7h1k7k4ee

（这里只是说它有点乱，因为把奇怪的空间放到代码盒中的东西mabob XD）如果你需要它，我的代码是：

package org.game.engine;
import java.net.MalformedURLException;
import java.util.logging.Level;
import java.util.logging.Logger;
import sun.audio.*;
import java.io.IOException;
import java.io.*;
import java.net.URL;

     private ContinuousAudioDataStream audiostream;
     private boolean checkforlooped = false;

    public SoundEngine(String name) {
    filename = name;
    try {
        in = new FileInputStream(filename);
    } catch (FileNotFoundException ex) {
        Logger.getLogger(SoundEngine.class.getName()).log(Level.SEVERE, null, ex);
    }
    try {
        as = new AudioStream(in);

        Logger.getLogger(SoundEngine.class.getName()).log(Level.SEVERE, null, ex);
    }
    }

    public void start() {
        if (checkforlooped) {
                try {
        in = new FileInputStream(filename);
        } catch (FileNotFoundException ex) {
          Logger.getLogger(SoundEngine.class.getName()).log(Level.SEVERE, null, ex);
        }
       try {
            as = new AudioStream(in);
        } catch (IOException ex) {
            Logger.getLogger(SoundEngine.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    AudioPlayer.player.start(as);
    }
    public void stop() {
        AudioPlayer.player.stop(as);
    }
    public void stoploop() {
        AudioPlayer.player.stop(audiostream);
        AudioPlayer.player.stop(as);
    }
    public void loop() {
    if (!checkforlooped) {
    try {
        data = as.getData();
        audiostream = new ContinuousAudioDataStream(data);
    } catch (IOException ex) {
        Logger.getLogger(SoundEngine.class.getName()).log(Level.SEVERE, null, ex);
    }
    AudioPlayer.player.start(audiostream);
    checkforlooped = true;
    } else {AudioPlayer.player.start(audiostream);}
    }
    }

AudioPlayer可以播放一次文件，但不能循环播放
