Wave_write Objects
------------------

Wave_write objects, as returned by `open()', have the following methods:

`close()'
     Make sure NFRAMES is correct, and close the file.  This method is
     called upon deletion.

`setnchannels(n)'
     Set the number of channels.

`setsampwidth(n)'
     Set the sample width to N bytes.

`setframerate(n)'
     Set the frame rate to N.

`setnframes(n)'
     Set the number of frames to N. This will be changed later if more
     frames are written.

`setcomptype(type, name)'
     Set the compression type and description.

`setparams(tuple)'
     The TUPLE should be `(NCHANNELS, SAMPWIDTH, FRAMERATE, NFRAMES,
     COMPTYPE, COMPNAME)', with values valid for the `set*()' methods.
     Sets all parameters.

`tell()'
     Return current position in the file, with the same disclaimer for
     the `Wave_read.tell()' and `Wave_read.setpos()' methods.

`writeframesraw(data)'
     Write audio frames, without correcting NFRAMES.

`writeframes(data)'
     Write audio frames and make sure NFRAMES is correct.

Note that it is invalid to set any parameters after calling
`writeframes()' or `writeframesraw()', and any attempt to do so will
raise `wave.Error'.
