The Audyssey mics are batch calibrated with a generic calibration file that is proprietary to Audyssey and pre-loaded in the Audyssey software. Without the calibration file, the mic is pretty useless for measurements using any other system. I suppose you could send it out to one of the microphone calibration companies. They could generate a cal file for it which you could load into some other measurement system, but that seems like overkill for a cheap, $3 mic.
OmniMic and XTZ come with a pre-calibrated mic, and the associated calibration file is pre-loaded into their software. That is a big part of what makes them "Plug 'N Play". REW has a method to load a calibration file for any mic, assuming the calibration file is known and available. However, the steepest part of the learning curve for REW is getting the appropriate cal file, figuring out how to load the cal file into the program and verifying it's performance.
