Where can I send my miss to have a calibration file generated?

Hi Brian,

Depending on the microphone, you may be able to get the microphone calibration file from the manufacturer (instead of sending it off to a lab). What kind of mic is it?

Do you happen to have the calibration file for the DBX RTA-M?

Hi sndman2004,

You will need to contact dbx (or the reseller that you purchased the mic from) for the mic correction file. Each microphone is going to have a unique file that is generated based on the frequency response of that particular mic.

Best regards,

There is no calibration file for that mic, and dbx is not the manufacturer. The mic is made by an oversees manufacturer and relabeled FOR many companies around the world. I can name at least 4-5 in the US that sell the mic. It's an entry level mic and therefore is not individually measured. dbx isn't likely to be of any help to you. The links provided in this thread are your "best bet". I can provide a "poor man's" correction file (which you can also create if you have a reference mic, a stereo bar, and a wide range loudspeaker), but for $50. you can get a very accurate correction file from Cross Spectrum using the Larson Davis gear that was designed for the purpose and a very accurate traceable reference mic.

I'm new to the forum and also the use of Smaart v.7.
I have the files MIC Calibration for my M30 but when I try to import Smaart tells me that is not compatible.
Can you help me??

Hmm that file seems to import fine for me. Are you using File->Import Mic Correction Curve?
