 recorder = OmRecorder.wav(
                new PullTransport.Default(mic(), new PullTransport.OnAudioChunkPulledListener() {
                    @Override
                    public void onAudioChunkPulled(AudioChunk audioChunk) {
                        animateVoice((float) (audioChunk.maxAmplitude() / 200.0));
                    }
                }), file());

   recorder = OmRecorder.pcm(
                  new PullTransport.Default(mic(), new PullTransport.OnAudioChunkPulledListener() {
                      @Override public void onAudioChunkPulled(AudioChunk audioChunk) {
                          animateVoice((float) (audioChunk.maxAmplitude() / 200.0));
                      }
                  }), file());

## For Skip Silence

  // FOR SKIP SILENCE
 recorder = OmRecorder.wav(
        new PullTransport.Noise(mic(),
            new PullTransport.OnAudioChunkPulledListener() {
              @Override public void onAudioChunkPulled(AudioChunk audioChunk) {
                animateVoice((float) (audioChunk.maxAmplitude() / 200.0));
              }
            },
            new WriteAction.Default(),
            new Recorder.OnSilenceListener() {
              @Override public void onSilence(long silenceTime) {
                Log.e("silenceTime", String.valueOf(silenceTime));
                Toast.makeText(WavRecorderActivity.this, "silence of " + silenceTime + " detected",
                    Toast.LENGTH_SHORT).show();
              }
            }, 200
        ), file()
    );

 @NonNull private File file() {
    return new File(Environment.getExternalStorageDirectory(), "demo.wav");
  }

## Configure Audio Source

  return new PullableSource.Default(
         new AudioRecordConfig.Default(
             MediaRecorder.AudioSource.MIC, AudioFormat.ENCODING_PCM_16BIT,
             AudioFormat.CHANNEL_IN_MONO, 44100
         )
     );

## Start & Stop Recording

       recorder.startRecording();
       recorder.stopRecording();
