  recorder = OmRecorder.wav(

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
         )
     );
     
   To Enable NoiseSuppresor (android.media.audiofx.NoiseSuppressor)
   
   return new PullableSource.NoiseSuppressor(
          new PullableSource.Default(
              new AudioRecordConfig.Default(
                  MediaRecorder.AudioSource.MIC, AudioFormat.ENCODING_PCM_16BIT,
                  AudioFormat.CHANNEL_IN_MONO, 44100
              )
          )
      );   
      
   To Enable AutomaticGainControl (android.media.audiofx.AutomaticGainControl)
   
   return new PullableSource.AutomaticGainControl(
            new PullableSource.Default(
                new AudioRecordConfig.Default(
                    MediaRecorder.AudioSource.MIC, AudioFormat.ENCODING_PCM_16BIT,
                    AudioFormat.CHANNEL_IN_MONO, 44100
                )
            )
        );    
        
   and if you want both NoiseSuppressor & AutomaticGainControl :-
   
   return new PullableSource.AutomaticGainControl(
           new PullableSource.NoiseSuppressor(
               new PullableSource.Default(
                   new AudioRecordConfig.Default(
                       MediaRecorder.AudioSource.MIC, AudioFormat.ENCODING_PCM_16BIT,
                       AudioFormat.CHANNEL_IN_MONO, 44100
                   )
               )
           )
       );
