bzip2 is a new compressor that uses another compression algorithem like zip
and compress. gzip, compres,... are very similar, bzip2 is totally different.
After the great compression era in the 80s/beginning 90s the experts thought
compression algorithms can't be improved anymore in great steps. Then in the
ending 90s a guy (or more ?) found a totally different way to compress data
and its better than 'the old way'. Especially on on uncomporessed wav files
its much better compared to zip-based compressors.
Bzip(2) is another expample to never give up to find a better solution there
is sure one you only have to find it.

With b2zip -d.
Type bzip2 --help for more paramters. There exists also a bzip command.
Don't ask me whats the differecnce about b2zip and bzip, probably is
b2zip an improved version of bzip. I don't use them often. .gz-files
are still more used than -.bz2.
mc probably handles this format now too.
