  While trying to convert an .AU file to something my Replay 4 cart. could
handle, I asked for help converting the file here on the net.  One of the
replies (sorry I lost your name) told me that the .AU file is a 12 bit
Sparc station file.  If such is true, then when I ran the DIGISTUFF convertor
file that turned it into an 8-bit unsigned .SND  file, why wasn't the file
size cut down by 30%?  (In fact, it was the same size!)  If there is some
funny math going on,  where might I find a 12 bit sound player to take
advantage of the extra sampling?  Or was that somehow done by the convertor?
The converted sound quality is on par with what I expected from an 8000 HZ
sample comprised of only 1.2 Meg, but lasting 6 minutes.  Is a Sparc
station's reproduction really supposed to be that much better?
