I welcome all submissions. Please, send me any little code bits
you think might be useful for someone else. Also, if you have
any downloads from Dr. BuB, please send them here. I'd like to
post them to save people the phone call.
Send bug reports to todd@ivucsb.sba.ca.us
NOTE: Thanks to Tom Cunningham at Motorola for sending me a copy of
the latest version of srec.
If you want to find out how to download the following files, send the
following line [subject line is ignored] to dsp@ivucsb.sba.ca.us
send HOWTO
Anything ending in .uu is generally tar'ed and compressed source that
has been uuencoded. Unless otherwise noted, you should be able to
extract the source using the following:
uudecode file.uu
If a file.tar.Z file results, try
zcat file.tar.Z | tar xvf -
If a file.Z file results, try
uncompress file.Z
Please note that anything that has already been uuencoded will not need
to be sent using 'sendu'.

By the way, I haven't finished "Dolby Surround: The NeXT Generation"
and it probably won't be done before the end of the year. However, for
your entertainment (and as a treat for those who actually bothered to
read this far), I have included my code for outputing everything BUT
the center channel. Using this code, you should be able to derive just
about everything needed to build a Dolby Surround decoder the right way.
Good luck... you're going to need it! If you don't understand adaptive
filtering, you won't be able to understand the code. I'm sorry, but I
just don't have the time lately to do a proper overview. The code is
documented somewhat, however.
