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 ;-)
