Question

有人知道是否需要将audiorecord和audiotrack以特殊方式/类型的线程，可运行，服务等分开，以便它能够一起工作？现在我可以开始录音，然后听音乐也没有问题。

但是，如果我在录音时开始和停止音频录音，那么音频录音开始输出0就像它被静音一样。（但它没有静音或停止）

如果我开始录音电话然后是录音带，那么录音带也会被静音＃34;

同样奇怪的是，当我拔下并插上我的有线耳机时，它将再次开始录制/输出录音而不是0（这让我觉得我的手机联想B和联想C2太便宜了（电路/硬件问题）或构建问题）但我不知道。

任何人都突然听到这个问题并且＃34; audiorecord或audiorecord响应拔出/插入有线头设备而没有应用任何设置/方法？

class myRecordAndPlayer(){

public void initiateRecorder() {
    if(audio.getMode()!=AudioManager.MODE_IN_CALL) {
        audio.setMode(AudioManager.MODE_IN_CALL);
        //audio.setSpeakerphoneOn(false); for mode in com (mode in com produces more echo/crosstalk)
    }

    rec = true;
    Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {
            android.os.Process.setThreadPriority(Process.THREAD_PRIORITY_URGENT_AUDIO);
            AudioRecord audioRecorder = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE,

未经测试。

private Thread audioRecordThread
private AudioRecord audioRecorder;
private AudioTrack audioTrack;

public void initialize() {
    audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, SAMPLE_RATE, AudioFormat.CHANNEL_OUT_MONO,
                        AudioFormat.ENCODING_PCM_16BIT, BUF_SIZE, AudioTrack.MODE_STREAM);

    audioRecorder = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE,
                    AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT,
                    AudioRecord.getMinBufferSize(SAMPLE_RATE, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT) * 10);

    audioRecordThread = new Thread(new Runnable() {
            public void run() {
                writeAudioDataToAudioTrack();
            }
        });
}

public void start() {
    audioTrack.play();
    audioRecorder.startRecording();
    audioRecordThread.start();
}

private void writeAudioDataToAudioTrack() {
    while(AudioRecord.RECORDSTATE_RECORDING == audioRecord.getRecordingState()) {
        audioTrack.write(bufToPlay, 0, bufToPlay.length);
    }
}
