      Parameters
      ----------
      coordinates : str
      proto : The proto to fill. Must have a string field called "url".
      data : str, bytes, BytesIO, numpy.ndarray, or file opened with
              io.open()
          Raw audio data or a string with a URL pointing to the file to load.
          If passing the raw data, this must include headers and any other bytes
          required in the actual file.
      mimetype : str
          The mime type for the audio file. Defaults to "audio/wav".
          See https://tools.ietf.org/html/rfc4281 for more info.
      start_time : int
          The time from which this element should start playing. (default: 0)
      sample_rate: int or None
          Optional param to provide sample_rate in case of numpy array
