Hello Antoine,
Thanx for this brief explanation and for the link. I will dig a little bit to understand the process. Now if people know some literature about this topic, they are welcome. ++

for convolution purpose there are afaik lots of implementation you can even do your own in pure pd (without externals) the last externals I saw doing this was in the Hao or Cream library from MSH Paris Nord [1] I think the lib is shipped with lots of impulse to do binaural rendering, wich is great ! be careful there are lots of incompatibilies with Vanilla (I made a Makefile but I stuck with some crashes due to some hacks in Pd's code)
btw those only do convolution not impulse response extraction, for which you need to do "deconvolution" by knowing the source impulse and it's response some software are dedicated to this task, but I don't know any on linux
the old way to record impulse response is to fire some explosive or gun but they make a weighted noise and thus the impulse will be "colored" by the impulse source. once you have recorded an impulse, edit it to remove onset time and then convolve it with your live sound. the key to make a convolution reverb sounding great is to have a good impulse.
cheers

So far as I know it's only MaxMSP: http://www.alexanderjharker.co.uk/Software.html
But I'm sure someone here will know of a pd external for convolution (?)
All the best, Peiman

Hello Peiman,
Thanx for the links, it was instructive. Do you know where i could find Pd patch about impulse response ? ++
