'Create an audio/* type MIME document.
_audiodata is a string containing the raw audio data.  If this data
can be decoded by the standard Python `sndhdr\' module, then the
subtype will be automatically included in the Content-Type header.
Otherwise, you can specify  the specific audio subtype via the
_subtype parameter.  If _subtype is not given, and no subtype can be
guessed, a TypeError is raised.
_encoder is a function which will perform the actual encoding for
transport of the image data.  It takes one argument, which is this
Image instance.  It should use get_payload() and set_payload() to
change the payload to the encoded form.  It should also add any
Content-Transfer-Encoding or other headers to the message as
necessary.  The default encoding is Base64.
Any additional keyword arguments are passed to the base class
constructor, which turns them into parameters on the Content-Type
header.'
