Java：声音传输问题

2015-12-15 99 views

我有一个SoundManager类和Sound类设置，以便我可以从我的代码中的任何位置播放声音。我的问题是，在家时，声音片段播放良好（将其转换为.wav的正确音频格式后）。然而，在学校，该程序崩溃，说音频格式不支持。有没有一种方法可以让音频在任何系统上运行，而不管Java版本如何？Java：声音传输问题

的Wav应始终支持，但不一定是所有采样率等等。你得到的确切例外信息是什么？ –

@ greg-449由于我目前不在学校，所以我不确定确切的消息，但是我的'.wav'的音频格式是：'PCM_SIGNED 44100.0Hz，16位，立体声，4字节/帧， endian'，它说学校不支持 –

这看起来像普通的CD质量音频。系统可能不支持“小端”或类似的东西。您将不得不查看输出SourceDataLine支持的格式，以查看它是否与支持的格式匹配。 –

你可以看到，在Java听起来使用像一台机器上的API支持格式：

public static void displayMixerInfo() 
{ 
    Mixer.Info [] mixersInfo = AudioSystem.getMixerInfo(); 

    for (Mixer.Info mixerInfo : mixersInfo) 
    { 
    System.out.println("Mixer: " + mixerInfo.getName()); 

    Mixer mixer = AudioSystem.getMixer(mixerInfo); 

    Line.Info [] sourceLineInfo = mixer.getSourceLineInfo(); 
    for (Line.Info info : sourceLineInfo) 
     { 
     showLineInfo(info); 
     } 

    Line.Info [] targetLineInfo = mixer.getTargetLineInfo(); 
    for (Line.Info info : targetLineInfo) 
     { 
     showLineInfo(info); 
     } 
    } 
} 


private static void showLineInfo(Line.Info lineInfo) 
{ 
    System.out.println(" " + lineInfo.toString()); 

    if (lineInfo instanceof DataLine.Info) 
    { 
    DataLine.Info dataLineInfo = (DataLine.Info)lineInfo; 

    AudioFormat [] formats = dataLineInfo.getFormats(); 
    for (AudioFormat format : formats) 
     { 
     System.out.println(" " + format.toString()); 
     } 
    } 
}

在我的Mac此显示：
