So, you read the first couple of posts, but you didn't read the step-by-step guide?
Too bad. There are a lot of these microphones out there. And this is the one I could use to start practicing with REW for free (and I am not alone with this...).
I just ran through that a few minutes ago. It didn't really tell me anything I couldn't figure out myself but it gave me a good template for publishing graphs. It's was a good idea to establish some guidelines about this.
Reading some post here helped me to identify/understand my ASIO problem/misunderstanding (I don't know if your PDF could help with that or not, we won't know but it doesn't matter now).

I think I see a workaround here:
Connect the USB mic to a PC, apply the calibration in real-time with a PC software, output the corrected signal from the PC to the V.AUX L input on the AVR (where calibrated microphones meant to be connected on my AVR, but this could vary from AVR to AVR and may not available at all on some...).
But I assumed that the digital (optical) V.AUX is also acceptable. If we are limited to the analog V.AUX L then we need a calibration for our DAC (analog PC output). And I guess that's the case since that optical input also has Optical 4 label despite it's located in the "V.AUX" block.
And I don't know about such a software but I guess REW could easily expanded with support for this.
Here is the result of my first REW trial with an uncalibrated Audyssey mic (so, ignore the absolute sound pressure level, the AVR's Master Volume was set to 0db and REW was set to -15db, the noise floor was low). Edited by janos666 - 2/5/13 at 11:59am
