Mic calibration files

[tickertape]

My apologies, I originally posted this elsewhere, but probably should have posted it here.


I am hoping to use a mic I own with REW, but this particular mic has no electronic calibration file. It does however, have all the calibration data in a paper document, in tabular and graphic format. This data could easily be keyed-in to an electronic file, if I only knew the required format acceptable to REW.

Anyone know if this is possible ? ...and what the file format might be ?

If you go to the download page, you can find several calibration files there (like this one)

Save it to your desktop and either append a .txt to the file or simply dump it into notepad and you'll see it's quite simple to read.

The format is frequency (space) decibel_value

So, from a cal file if it reads:

20 -5.50

This means at 20Hz the mic is outputting 5.5dB low.

You may start and stop at any frequency with any intervals. REW will fill in the blanks between your values. After the top value, REW will extend from that value higher.

Save the text file you create as a filename.cal file

Let me know if you have any trouble and I'll help.

Thank you very much, brucek.
That was exactly the info I was looking for.

I'll get back to you once I've had a chance to try it out.
