通过套接字从 android 向 PC 发送语音时出现噪音

Noise in sending voice from android to PC over socket

我正在尝试通过套接字从 android 向 PC 发送语音。我的代码可以运行,但是在PC端我听到很多噪音,我什至听不到任何声音。

这是我正在使用的 android 代码:

     byte buffer[]=new byte[1024];
     int buffersize = AudioRecord.getMinBufferSize(SAMPLE_RATE, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT);
         mic=new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize);
         mic.startRecording();
               
                  while(running){
                        count=mic.read(buffer, 0, buffer.length);
                        if(count>0){
                           OutputStream.write(buffer, 0, count);
                        }
                  }

这是 PC 代码:

    float sampleRate=44100;
    int sampleSize=16;
    int channel=1;
    boolean sign=true;
    boolean bigendian=true;
    AudioFormat format=new AudioFormat(sampleRate, sampleSize, channel, sign, bigendian);
    
    SourceDataLine voiceLine;
    DataLine.Info LineInfo=new DataLine.Info(SourceDataLine.class, format);
    if(AudioSystem.isLineSupported(LineInfo)){
        System.out.println("Line Supported...");
    }else{
        System.out.println("not supported Line...");
    }
    voiceLine = (SourceDataLine) AudioSystem.getLine(LineInfo);
    voiceLine.open(format);
    voiceLine.start();
    byte buffer[] = new byte[1024];
    inputStream=new BufferedInputStream(connection.getInputStream());    
    while(true){
                 count=inputStream.read(buffer,0,buffer.length);
                 InputStream in;
                 in=new ByteArrayInputStream(buffer);
                 AudioInputStream ais=new AudioInputStream(in, format, buffer.length /format.getFrameSize());
                 ais.read(audio, 0, count);
                 voiceLine.write(audio, 0, count);
            }

到目前为止我测试的内容:

到目前为止我尝试过的:

但是一无所获

最后我自己解决了这个问题。

原来只好改成bigendian=false;,现在可以了
