getAudioInputStream 格式无效，尝试在 Java 中播放声音 [英] Invalid format with getAudioInputStream, trying to play a sound in Java

问题描述

我正在尝试用 Java 播放基本的声音...

I'm trying to just play a basic sound in Java...

这是我的代码，基于在各种论坛上找到的代码:

Here is my code, based on the code found on various forums :

    Clip clip = null;

    try {
        clip = AudioSystem.getClip();
        AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File(url));
        clip.open(inputStream);
    } catch (LineUnavailableException | IOException | UnsupportedAudioFileException ex) {
        Logger.getLogger(Pomodoro.class.getName()).log(Level.SEVERE, null, ex);
    }

    return clip;

我检查过:new File(url).exists(); 返回true，我检查过文件类型确实是音频WAV (audio/x-wav)，我检查过问题坚持使用另一个文件...我不明白我做错了什么.

I checked that : new File(url).exists(); returns true, I checked that the file type is really audio WAV (audio/x-wav), I checked that the problem persists with another file... I don't understand what I'm doing wrong.

错误:

Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.lang.IllegalArgumentException: Invalid format
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.createStream(PulseAudioDataLine.java:142)
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:99)
    at org.classpath.icedtea.pulseaudio.PulseAudioDataLine.open(PulseAudioDataLine.java:283)
    at org.classpath.icedtea.pulseaudio.PulseAudioClip.open(PulseAudioClip.java:402)
    at org.classpath.icedtea.pulseaudio.PulseAudioClip.open(PulseAudioClip.java:453)

帮助！

我终于找到了我的问题的副本.抱歉打扰了.

AudioInputStream 不工作

我的代码变成了:

    Clip clip = null;

    try {
        AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File(url));
        DataLine.Info info = new DataLine.Info(Clip.class, inputStream.getFormat());
        clip = (Clip)AudioSystem.getLine(info);
        clip.open(inputStream);
    } catch (LineUnavailableException | IOException | UnsupportedAudioFileException ex) {
        Logger.getLogger(Pomodoro.class.getName()).log(Level.SEVERE, null, ex);
    }

    return clip;

尽管如此，我很惊讶我以前的代码不起作用.有时，我对 Java 感到非常绝望...

Nevertheless, I'm very surprised that my previous code didn't work. Sometimes, I'm quite desperate by Java...
