Thanks Richard.

Maybe you're exactly right, because if i can find any free software
that's relevant to what i want, then i can probably get it to Debian.
(If i have something specific, then can bring it up here in fact if i
have trouble installing it.)

How do you normally access usenet?

In the old days (meaning, decades ago) i used to read usenet with rn.

I suppose a modern equivalent would be google groups, but if i do get
back in the usenet scene, i'm wondering if there's a more
command-liney thing or just other alternatives to consider before
walking down the google trail.

Anyhow, whether or not you have an answer about the best way to go to
usenet, i appreciate the suggestion because that group (comp.dsp) is
probably where i can find what i'm looking for if it exists at all.
