Java：聲音傳輸問題

2015-12-15 126 views

我有一個SoundManager類和Sound類設置，以便我可以從我的代碼中的任何位置播放聲音。我的問題是，在家時，聲音片段播放良好（將其轉換爲.wav的正確音頻格式後）。然而，在學校，該程序崩潰，說音頻格式不支持。有沒有一種方法可以讓音頻在任何系統上運行，而不管Java版本如何？Java：聲音傳輸問題

的Wav應始終支持，但不一定是所有采樣率等等。你得到的確切例外信息是什麼？ –

@ greg-449由於我目前不在學校，所以我不確定確切的消息，但是我的'.wav'的音頻格式是：'PCM_SIGNED 44100.0Hz，16位，立體聲，4字節/幀， endian'，它說學校不支持 –

這看起來像普通的CD質量音頻。系統可能不支持「小端」或類似的東西。您將不得不查看輸出SourceDataLine支持的格式，以查看它是否與支持的格式匹配。 –

你可以看到，在Java聽起來使用像一臺機器上的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此顯示：
