class_docstr: Audio object used to store audio objects in Aim repository..
  
  Currently, audio formats are limited to mp3, wav, flac
  
  Args:
       data: file path, bytes, io.BaseIO or numpy.array (only for WAV)
       format (:obj:`str`): Format of the audio source
       rate (:obj:`int`): Rate of the audio file, for WAV defaults to 22500
       caption (:obj:`str`, optional): Optional audio caption. '' by default.
docstr: This method converts WAV to Numpy array.
  Other audio formats are not supported at this moment.
  
  Returns: numpy array
