Applications often enable the loading of a calibration file.

One such application is Room EQ wizard (REW).
Follow this REW user guide link and read the ‘ Mic/Meter Calibration’ section and following section for more details.

thanks for replying.

I want to create something myself. still not enough information for to to use that data.

the link tells
" It should contain the actual gain (and optionally phase) response of the meter or microphone at the frequencies given, these will then be subtracted from subsequent measurements. "

but, what is the range, filter type ? sorry for the stupid question cause I'm a newbie...

Hi, I am also trying to figure out how to apply the calibration .txt files to my microphone response without using REW. I am using matlab to record responses using my UMIK-1 mic, FFT the response to analyze it in the frequency domain, where I would assume I need apply this cal file. Is there an equation for applying it or a description of what the data actually is so I can figure out how to apply it with an equation?

Have you tried using REW? My bet is you'll find it does everything you need pretty well, without this complexity. And I'm saying this as someone who has used Matlab extensively in the past.
