java - 为什么 AudioSystem.getAudioInputStream() 会抛出 IllegalArgumentException

Question

我正在 Eclipse 中开发游戏。我有一些播放 wav 文件的代码:

public void play(String path) {
    try {
        Clip clip = AudioSystem.getClip();
        URL soundURL = getClass().getResource(path);
        clip.open(AudioSystem.getAudioInputStream(soundURL));
        clip.play();
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

问题是，即使我有一个有效的路径(我已经测试过)，我得到一个错误，上面写着:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Invalid format

这是完整的错误消息:

我对此很困惑，我只想播放一个声音! ;(如果你们中的一个可以帮助我，我将非常感激!

Java 显然在提示一种格式，这很可能是您的 .wav 文件的 AudioFormat。该文件可能以未在 java 中实现的方式压缩，因此无效。 .wav 文件通常包含原始 PCM 数据，但它们也可以以各种方式压缩。

尝试使用音频转换器/编辑器将 .wav 文件的格式更改为 PCM (Audacity)

支持的格式列表:
