音频输入流不工作 [英] AudioInputStream is not working

问题描述

我试图在用户每次按下按钮时播放 .wav 声音，但会引发异常:

I'm trying to play a .wav sound every time the user presses a button, but an exception gets thrown:

Exception in thread "Thread-0" 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)
    at Uber.play(Uber.java:534)
    at Uber$5.run(Uber.java:340)
    at java.lang.Thread.run(Thread.java:724)

代码如下:

//Play Audio File
public void play(String file) throws LineUnavailableException, UnsupportedAudioFileException, IOException
{
    AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File(file));
    Clip clip = AudioSystem.getClip();
    clip.open(inputStream);
    clip.start();
}

推荐答案

我设法让它发挥作用.这是我使用的代码.请记住，我需要它只是为了播放短的 beep.wav 声音.较长的声音文件似乎有些麻烦.让我知道它是否适合你们，以及你们是否设法使用此代码播放更长的声音.

I managed to get it working. This is the code that I used. Keep in mind that I needed this just to play a short beep.wav sound. It seems to have some trouble with longer sound files. Let me know if it works for you guys and if you manage to play longer sounds with this code.

public void play(String file) throws LineUnavailableException, UnsupportedAudioFileException, IOException
    {

    try 
        {   
            AudioInputStream inputStream = AudioSystem.getAudioInputStream(this.getClass().getResource(file));
            AudioFormat format = inputStream.getFormat();
            DataLine.Info info = new DataLine.Info(Clip.class, format);
            Clip clip = (Clip)AudioSystem.getLine(info);
            clip.open(inputStream);
            clip.start();
        }

    catch (IOException | LineUnavailableException | UnsupportedAudioFileException e1)
        {
            e1.printStackTrace();
        }
    }
