The wave module provides a convenient interface to the WAV sound
format. It does not support compression/decompression, but it does support
mono/stereo.
The wave module defines the following function and exception:
If file is a string, open the file by that name, other treat it
as a seekable file-like object. mode can be any of
'r', 'rb'
Read only mode.
'w', 'wb'
Write only mode.
Note that it does not allow read/write WAV files.
A mode of 'r' or 'rb' returns a Wave_read
object, while a mode of 'w' or 'wb' returns
a Wave_write object. If mode is omitted and a file-like
object is passed as file, file.mode is used as the
default value for mode (the "b" flag is still added if
necessary).
