    For sounds loaded from a file leave this blank and then give the `Expected duration` below for 
    visualisation purposes. See :ref:`startStop` for details.

    This sound can be described in a variety of ways:
      
      * a number can specify the frequency in Hz (e.g. 440)

      * a filename, which can be a relative or absolute path (mid, wav, and ogg are supported).
