如何传输音频缓冲区直接播放

Question

我试图创建一个音频缓冲区并将他发送到一个新类.在这个类中,我将使用AudioTracker播放此缓冲区,但它不起作用.我可以按时听到声音,但声音就像一个halleffect.我没有想到我的错误,也没有找到这个问题的答案.我希望你能帮助我.(对不起,我的英语不是最好的)Sorcecode:

public class input {
private static final String TAG = "Aufnahme";
private AudioRecord recorder = null;
private boolean isRecording = false;
private int SAMPLERATE = 8000;
private int CHANNELS = AudioFormat.CHANNEL_CONFIGURATION_MONO;
private int AUDIO_FORMAT = AudioFormat.ENCODING_PCM_16BIT;
private int bufferSize = AudioRecord.getMinBufferSize(SAMPLERATE, CHANNELS,
        AUDIO_FORMAT);
private Thread recordingThread = null;

public void startRecording() {
    recorder = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLERATE,
            CHANNELS, AUDIO_FORMAT, bufferSize);

    recorder.startRecording();
    isRecording = true;

    recordingThread = new Thread(new Runnable()

    {
        public void run() {
            writeAudioData();
        }

    });
    recordingThread.start();

}

public void stopRecording() {
    isRecording = false;
    recorder.stop();
    recorder.release();
    recorder = null;
    recordingThread = null;
}

private void writeAudioData() {

    byte data[] = new byte[bufferSize];

    while (isRecording) {

        recorder.read(data, 0, bufferSize);
        send(data);

    }
}

private void send(byte[] data) {

    int minBufferSize = AudioTrack.getMinBufferSize(8000,
            AudioFormat.CHANNEL_CONFIGURATION_MONO,
            AudioFormat.ENCODING_PCM_16BIT);

    AudioTrack at = new AudioTrack(AudioManager.STREAM_MUSIC, 8000,
            AudioFormat.CHANNEL_CONFIGURATION_MONO,
            AudioFormat.ENCODING_PCM_16BIT, minBufferSize,
            AudioTrack.MODE_STREAM);

    at.play();
    at.write(data, 0, bufferSize);
    at.stop();
    at.release();

}

好的，我找到了问题所在。霍尔效应来自实时录制的扬声器声音。糟糕的错误。
