From page 44 of the REW guide;
Step 5: REW Microphone Calibration
Note: With certain USB microphones, calibration is not necessary. Currently, only the UMIK-1 is recognized by the REW beta software as having a sensitivity parameter that allows REW to calibrate the microphone automatically. All other microphones must be configured manually using this procedure.
Ah, the reason why I didn't have to calibrate is I'm using the UMIK 1.
