pybasswma.py - is ctypes python module for
BASSWMA - extension to the BASS audio library,
enabling the playback of WMA files and network streams.
The audio tracks of WMV files can also be played.
WMA file encoding and network broadcasting functions are also provided.

Requirements
============
BASS 2.4 is required. The Windows Media Format modules (v9 or above) are
also required to be installed on the user's system. They are installed with
Windows Media player, so will already be on most users' systems, but they
can also be installed separately (WMFDIST.EXE is available from the BASS website).
