Does anyone do a s/w 3rd octave equalizer that will work on a stereo
(non dolby etc) SPDIF output (from a mobo or soundcard)?

Not a comp.dsp question (unless you want someone to design and build it
for you, for the appropriate high fee). Use an audio gear forum
somewhere. "Google is your friend" (most of the time). Most digital
graphic EQs (and Room Correction systems) above seriously cheap
low-budget models have SPDIF interfaces.

I'm asking here because I cannot get an answer on audio NGs.
And I am looking for a PC based *software* solution, not a DSP board.
Does comp.dsp have room for questions concerning DSP s/w on PCs?

I just did a Google search for "pc software 1/3 octave eq" and got a ton of
hits. Many of them download for free.

This is a technical/engineering list (the "comp" is a bit of a clue) -
dsp maths, algorithms, some hardware design. Only a minority are
especially concerned with audio. They talk more about comms, radar,
filter design, etc. Try the musicdsp list for a list dedicated to audio
dsp.

It is an almost totally vague and undefined question. If you had
problems on an audio NG you will have even more here! Your question
implies that you want to use one PC to process an SPDIF signal input
from some other machine. And presumably output it through the SPDIF
output of the same card. There is any amount of free and commercial
audio software on PCs etc that will one way or another enable audio
input from a soundcard (e.g. SPDIF input) to be processed through
plugins etc, and out again. Bound to be a graphic equaliser plugin
somewhere; more if you are prepared to spend money. Can't think of one
offhand, I don't use such things. You haven't even mentioned what OS you
are running. Vista? Linux? Since you didn't answer to it, I will
~assume~ you are not trying to equalize output from a PC etc prior to
sending to the speakers; which is the most common reason to want to
process an SPDIF output from one machine on a second one. Some people do
even do that with PCs, e.g. using FOSS software on a Linux box.

I suggest you try the audio NGs again, but form your question ~much~
more precisely. Satte the task you are trying to perform,as clearly as
possible, not what you assume the solution might be. Oh, and even a DSP
board actually runs software. Different kind of chip (probably), but
software is software. And if you really do want to connect the SPDIF
output of a computer to some some second machine, the hardware DSP box
will likely be both cheaper and better.
