Slightly off-topic but there was mention of a proposal for porting HISSTools to Pd but it's a big job and there wasn't any momentum - this was a couple of years ago now.
Spoke to Harker a couple of weeks ago and this topic came up again. The (BSD) code's in good shape and he's parsed out much of the Max/dsp code to aid a port.
It's all still outside of my skills/time (and isn't that the general problem) but it would still be a worthhile additional lib to Pd, perhaps even just a few objects such as the convolution that's all over Live (for example) these days.
Just saying like.
Anyhow, good luck with it Jack, IR's are a fun topic.
REgards,
Julian

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.
