[linux-audio-dev] deconvolver for IR creation anyone?

[Uwe Koloska]

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 ;-)

Uwe
