Is this what everybody else already does?

Probably not; old devil latency would get in the way. However, you can filter
digitally with few artifacts generated, depending of course on what you're
looking for.

But you can compensate for latency after you get your signal back into
the computer, and before you add the inverted original test tone.

I suppose you could do this with the equipment you described IF you
synchronize the DAT machine and the CD player.

Which'd probably be almost impossible. But filtering's easy enough.

I think it would be pretty easy IF your DAT machine allows clocking to
SPDIF input while recording the analog input. I know I can do this
with my AudioMedia II card, which costs less than a DAT machine, but I
don't recall if my DA30 does this or not. I think yes.
