Then start Cadence, Jack and the alsa jack bridge.
Then started REW and choose Default Device as output. After this a rawjack device appears in Catia and a EQ can be added in front of it.
if you activate alsa-jack-brige in Cadence it overwrites you .asoundrc with a snd-aloop one

Just for curiosity, I am not very familiar with REQ, but what can you export from REW? Can you export the whole impulse response in some way?
You can export EQ settings as a file based on your measurement for various hardware or plugins (e.g. miniDSP). I was just interested in equalizing three frequencies on which I have have strong room modes (~40, 50 and 120 Hz). You can also show the correction settings as a table (frequency, Q-factor, damping) which you can use for any EQ (plugin or hardware) by setting the parameters by hand.
The feature list suggests that it is possible to export the measured impulse response as WAV. If you manage to do that, it would be fun to try to invert it and use the inverse in a convolution reverb. Octave can be used for that pretty easily. This should give you the highest degree of compensation for the transmission line you measured. This means that, if you put your head where the microphone was during the measurement, then the compensation will be not optimal as your Head Related Transfer Functions are not the mic response, but maybe it will work OK anyway, especially at low frequency I think.
If you have time to spare, try to give us your impulse response, if you figure out how to do it. I can try to calculate the inverse for you and we can give it a spin, and compare it with the EQ solution.
I wonder why DRC and sorts use complicated convolution filters and not just invert the IR. there must be a good reason for this (I hope)
