Wink Mic's for REW

Hi all,
Newby question. I apologize if this question has been addressed previously.
I purchased a RadioShack 33-4050 so that I can get started with REW and will down load the appropiate file.
I also have two B&K 4007 Measurement Mics with factory calibration charts that I would prefer to use.
Is it possible to transfer the factory data to a spread sheet or whatever file type that REW uses?
I have a Crown 48v PS and mixer for a line out to my PC. (XP with Sound Blaster X-Fi Elite Pro)
I also have an Audio Control SA-3050A Spectrum Analyzer.It doesn't have a line out but the mic seems to be a good one.
My main use of REW is to help me deal with some room issues.

Thanks, and many cheers,

Ernie Whalley

Yep, very simple. The mic calibration files are text files (even though they have a .cal extension), and consist of a list indicating frequency, response, phase. The phase is not needed. There should be a space between the frequency and response entries. Any frequency increments are allowed as REW fills in the blanks.

Download a mic cal file and drop it into Windows notepad to see the format. Create a file in notepad and save it, then change the extension to .cal. Load it into REW and examine the files graph for errors.

brucek,

Wow! - Thanks for the quick reply and info. I'll be sure to do that in mid December when I get home from Bonita Springs FL.
Cheers,
