java - 卡在java中播放wav文件上......需要一些指导

Question

我试图在按下按钮时在java中播放声音。所以我有类似以下内容:

public void playSound(File soundFile) {
    try {
        AudioInputStream stream = AudioSystem.getAudioInputStream(soundFile);
        AudioFormat format = stream.getFormat();
        DataLine.Info info = new DataLine.Info(Clip.class, format);
        Clip clip = (Clip) AudioSystem.getLine(info);
        clip.open(stream);
        clip.start();
    }
    catch (Exception e) {e.printStackTrace();}
}

然后我在buttonListener中调用actionPerformed中的方法:

playSound(new File("woow_x.wav"));

但它抛出 UnsupportedAudioFileException。这是说不支持 .wav 文件吗？我确认 wav 文件可以工作，所以我不知道问题是什么。我正在尝试在不使用阳光的情况下做到这一点。请让我知道这是如何正确完成的。谢谢。

文件的编码在其 header 中指定为0x55。我不确定 0x55 到底是什么，但我怀疑它是 mp3。不管怎样，它都不是 Java 支持的编码之一。

为了您的目的(并且如果许可证允许)，您可以使用音频编辑器将文件转换为支持的格式。 (这些由 AudioFormat.Encoding 中的静态字段枚举。)
