Export of impulse response

[antani]

I need to export the impulse response in wav format for elaboration in DRC.

Is the exported impulse response calibrated for mic and audio card compensation in REW?
As far as I know ETF is using mic calibration file just for graphs and it's not applying any correction to the pcm export....

No, the soundcard and mic calibration files are added when the frequency response etc graphs are created. The impulse is what is recorded raw with REW and everything else is generated from that....

Why not use REW to measure the room and create filters for the measurement to get the response you want, and then export the impulse response wav file of the filters....

Because the FIR filter I can automatically generate with DRC produces much better results compared with what I can manually or automatically get from REW.

Your soundcard response should have virtually no effect on the frequency response. As far as the mic response, you should be able to visualize its effects for yourself and then tweak the DRC with that in mind. In other words, put on that engineering cap and use your understanding of the test rig to interpret the data.
