I did run guitarix before. I even had some patches.

Guess it was my computer. Or maybe I needed to give it some more time. But nevertheless it's working now. Thanks for the theme tip.

The IRs generated by specmatch are good by the way. I was actually trying to make the guitar sound like a trombone, so I loaded a trombone sample into specmatch and then a sample of my clean strat clone, and got a very nice clean guitar sound. True, it wasn't the trombone I was after, but it surprised me that I got such a nice bold tone out of this.

If anyone's interested, I could get the guitar as a trombone by only loading a trombone sample into the IR.lv2. It takes some tuning, though.

hmm, I've been looking for the clean strat tone with specmatch. The Hendrix clean tone as in Little Wing.

It was not nearly similar to that tone, unfortunately. I already deleted the IR, since it wasn't what I was after, but I could recreate it if you are interested in trying it out.

It boosted the mids mainly in quite a warm way.

all good, I'll keep experimenting.. thanx

Here is the video witch inspired to create specmatch: https://www.youtube.com/watch?v=iYjdMi2VW9A
spechmatch + guitarix (tubescreamer+ amp) follow mainly the method David shows in his video.
Just, you didn't need to play the same rhythm/style as your reference tone, your record just needs to contain roughly the same Notes, to get what you are after. You must take care, that they don't clip. Filter out the high/low end on both tones (with the same settings), helps as well, for better match your goal.
Leave out the tubescreamer and the amp, indeed only works for non distorted reference tones.

any tool to create an IR form a recorded sweep and the inverse of the original?

These plugins do the job for you:

I know this plugin but I don't see an option to "deconvolve" two given wavs against each other.
GratisVolver works nicely with wine though: https://www.catt.se/download_area.htm

Oh I see, sorry, didn't get the question properly. I think it should be very easy to make a simple program with Octave, Julia or Python to do so. By the way, convolution with the inverted swept sine only works if the swept sine is linear. Otherwise, you also need to apply an amplitude envelope to obtain the correct inverse filter.

Hi,

in the meantime I found out about Aurora Plugins for Audacity. they have a version for Audacity 2.0 on Linux: http://www.angelofarina.it/Public/Auror ... 0.0/Linux/
