Each microphone has calibration file, that you obtain by providing serial number.  Room EQ Wizard uses this file to correct microphone output.  Microphone is calibrated for direct (straight) and omnidirectional (pointing up) response.  Microphone is $75 and software is free.

kijankithanks for the recommendation.

I used what  kijankithanks recommended and discovered a few problems with my recent speaker purchase. I am fixing these issues now but the REW software and mic are now an important part of my system.

thanks!

Thank You!

Thanks for the information.I bought the mike from MADISOUND for $111.55 with shipping.
It looked like it was L.75 plus freight from Great Britain.
Looking forward to getting it setup.

As some one with 4 measurement mics, and several measurement software kits your best bet is a phone with a calibrated mic! :)

I use this on my android with Audio Tools, which can read the calibration file and give me near perfect results.  It is not OSHA or NSF certified, but damn accurate, especially relatively.

Best,
