[wplug] Audio: Compression Utility?

[bgtrio at yahoo.com]

I am interested in the answer.

I would suggest checking out some of the .wav editors that have come out 
for linux lately, they typically have a lot of plug-in type effects.  I'd 
be shocked if there wasn't a LADSPA compression plug-in.

Last time I compressed a sound file this way I used cool-edit 95 
shareware.  Maybe it will run under wine, you can still find the 
shareware file if you look around.
