Is the following code (especially the listen() function) a proper way
to do it? I'm not exactly happy with the sound quality I get from
it... thanks for your help/comments in advance!

public class Main extends Activity {
private volatile Thread listener;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listen();
}
@Override
protected void onPause() {
super.onPause();
stopListen();
}
private void listen() {
listener = new Thread() {
@Override
public void run() {
Thread thisThread = Thread.currentThread();
android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO);
int bufferRead = 0;
int bufferSize = AudioRecord.getMinBufferSize(8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
short[] tempBuffer = new short[bufferSize];
AudioRecord ar = new
AudioRecord(MediaRecorder.AudioSource.MIC, 8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize);
ar.startRecording();
AudioTrack at = new
AudioTrack(AudioManager.STREAM_MUSIC, 8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize * 2,
AudioTrack.MODE_STREAM);
at.play();
while (true) {
if (listener != thisThread) {
ar.stop();
ar.release();
at.stop();
at.release();
break;
}
bufferRead = ar.read(tempBuffer, 0, bufferSize);
at.write(tempBuffer, 0, bufferRead);
}
}
};
listener.start();
}
private void stopListen() {
listener = null;
}
}
