      await _stopAudioRecording();
      Datum? data = await getDatum();
      if (data != null) controller.add(data);
      debug('Audio recording paused - sound file : $_soundFileName');
    } catch (error) {
      warning('An error occured trying to stop audio recording - $error');
      controller.addError(error);
