java - 尝试播放音频 (.wav) 文件时没有声音

Question

我有一个非常简单的类，可以使用以下代码播放声音文件:

import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;

public class Sound{

private Clip sound;

public Sound(String location){

    try{ 
        sound = AudioSystem.getClip();
        File file = new File(location);
        sound.open(AudioSystem.getAudioInputStream(file));
    }
    catch(IOException | LineUnavailableException | UnsupportedAudioFileException error){
        System.out.println(error);
    }

}

public void play(){

    sound.start();

}

}

但是，当我创建此类的实例并对其调用播放函数时，我听不到任何声音。当声音开始和结束时我听到爆音，但不是实际文件。我也没有收到任何类型的错误。

我做错了什么？

使用它并注意这不是我的代码，它来自这里:How to play .wav files with java 我唯一做的就是把它贴在这里并稍微优化一下。

private final int BUFFER_SIZE = 128000;
private AudioInputStream audioStream;
private SourceDataLine sourceLine;
/**
 * @param filename the name of the file that is going to be played
 */
 public void playSound(String filename){
try {
    audioStream = AudioSystem.getAudioInputStream(new File(filename));
} catch (Exception e){
    e.printStackTrace();
}
try {
    sourceLine = (SourceDataLine) AudioSystem.getLine(new DataLine.Info(SourceDataLine.class, audioStream.getFormat()));
    sourceLine.open(audioStream.getFormat());
} catch (LineUnavailableException e) {
    e.printStackTrace();
} catch (Exception e) {
    e.printStackTrace();
}
sourceLine.start();
int nBytesRead = 0;
byte[] abData = new byte[BUFFER_SIZE];
while (nBytesRead != -1) {
    try {
        nBytesRead = audioStream.read(abData, 0, abData.length);
    } catch (IOException e) {
        e.printStackTrace();
    }
    if (nBytesRead >= 0) {
        @SuppressWarnings("unused")
        int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
    }
}
sourceLine.drain();
sourceLine.close();
}

希望对您有所帮助。
