Implementation

Future<void> unmuteMic() async {
  if (await recorder.isRecording()) {
    return;
  }

  Stream<Uint8List> userAudioStream = await recorder.startStream();

  userAudioStream.listen((bytes) {
    realtimeModel?.sendUserAudio(bytes);
    var volume = getAudioIntensityFromPcm16(bytes);
    _audioVolumeStreamController.add(volume);
  });
}
