A friend of mine has (16) Beyer MM1 measurement mics with calibration files but they are not formatted to load directly into Smaart without be manipulated.

beyerdynamic.com – MM-1 webpage
Beyer MM-1 spec sheet PDF
Beyer MM-1 user manual PDF

As soon as I figure out how to get the file formatted to load into Smaart, I will post the details.
