I would be interested in this project too. What I'm looking for is
actuallay an anti-reverb that will be able to cancel reverbs in a
listening room, well always in conjunction with the listener position.
The other useful thing would be a phase-filter to correct the phases
coming out from a two or three way loudspeaker to get clarity in the
sound similar to high-end speakers. I'm surprised that you mind modern
consumer soundcards not linear, after all the sigma-delta converters
used in most of todays soundcards are supposed to be perfectly linear
and it was one of the reasons of their adoption.

Hello,
I am looking for a deconvolver, that is able to produce impulse
responses from sinus sweeps (and especially the exponentially sweeping
sine wave introduced by Farina).
Do you have any suggestions or at least tips to start an
implementation by myself?
Recently I managed to use the mls tools from nwfiir to produce an IR
of my microverb.
I had to learn the hard way, that simple soundcards are not able to be
used as MLS source because of the non linearities. Even a simple
DA-AD loop gives a result wave that mls2imp cannot cope with. But an
empty loop with an US-122 (unfortunately not with linux for now) gives
something very near to a dirac impulse!
The hunt for the linux convolution reverb has started ;-)
