我目前有代码使用AudioRecord类从设备mic读取录音,然后使用AudioTrack类播放.

我的问题是,当我播放它时,它通过扬声器电话播放.

我希望它通过设备上的耳机播出.

这是我的代码:

public class LoopProg extends Activity {

 boolean isRecording; //currently not used
 AudioManager am;
 int count = 0;

 /** Called when the activity is first created. */
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
        am.setMicrophoneMute(true);
        while(count <= 1000000){
        Record record = new Record();  
        record.run();
        count ++;
        Log.d("COUNT", "Count is : " + count);
        }
    } 

   public class Record extends Thread{
      static final int bufferSize = 200000;
      final short[] buffer = new short[bufferSize]; …
