5c071fab8f The _comp_data() function never worked, it contained a reference to 
undefined 'nframes'.  Should be self._nframes.  (Andrew Dalke & kjpylint)

bb189dbcb0 Small corrections to comments that were cloned from aifc; moreover 
the description of setparams() was wrong.

wave.py: Include the tag of an unknown format in the exception.

afe3ebfa5c Use newer struct, which handles unsigned long right 1997-01-11 19:21:09 +00:00

36bb181cdf Rewrote _{read,write}_{short,long} to use the newly revamped struct 
module.  (Small problem: struct.pack() won't deal with the Python long
ints returned by struct.unpack() for the 'L' format.  Worked around
that for now.)

7bc817d5ba * Mass change: get rid of all init() methods, in favor of __init__() 
constructors.  There is no backward compatibility.  Not everything has
  been tested.

  comments)

8d733a00f0 added kludge for buggy soundfiler from SGI; when reading 0 frames, 
just set file pointer correctly instead of returning the complete
file.
