Important note: The included calibration files from Dayton is close to useless for precision work. I purchased 2 mics for the sake of comparing their consistency. The mics measured fairly similar without the calibration file, but once the individual calibration files were applied, they measured completely different from one another!
I have created a calibration file using a Kef LS50 loudspeaker and a CSL-Labs calibrated UMIK-1. You are free to use it. Its won't be perfect for your mic, but it must surely be better than the crap Dayton provides: https://pastebin.com/bkMm1EM0 (copy and save as .txt file)
