This sort of thing is my field of expertise. I assume you are using
Windows since you mentioned Cool Edit.

1/ Are these WAV/MP3 files or does a signal need to be captured
in real time?

2/ What version of Windows are you using?

3/ How old is your computer? Do you know if the sound card is 5.1
channel compatible?

Yes, XP Pro and CoolEDit Pro. The only thing not "Pro" is obviously me
:-)

These are files (test signals) produced in CoolEdit's audio tone
generator, saved as MP3's and then played back, also from CoolEdit.

Please see above.

We have a number of PC's. The ones in use for this are matching IBM
S51 Celerons, about 6-7 years old. But I have access to newer models.

The soundcards I bought for this purpose are Creative Audigy 2's with
_5.1 outputs_. However, I can not find how to make CoolEdit feed out
anything but 2 channel stereo.

If possible, I assume it involves cutting and pasting signals from the
editor to the 4 channel multi-track window, but I see no way to assign
each of these to a different 5.1 channel of the soundcard.

Any advice would be much appreciated.

The Audigy 2 should be suitable, but will not show up as separate devices,
which is what Cool Edit needs for multi-channel outputs. Most audio programs
do not offer the capability of splitting signals to various channels on a
single soundcard. You would need a proper multi-device sound card such as
a M-Audio Delta 1010LT or similar, or 2 cards. I don't think it is possible
to get 2 Audigy cards to work in one computer.

It would take me about an hour or 2 to throw a simple program together
that will play a couple of audio files and split the signal using an
open source DirectShow matrix filter to send signals to the various
outputs on the Audigy.

I'd be happy do do this for a bit of fun as long as you can wait a few
days until I can find some spare time. Email me if you are interested
