I only included the sensitivity data in the one file "zero band response zero degrees" as thats the file I was using for room measurement using REW and I am pointing the mic directly at the speakers being measured. If you are using all six files then load the sensitivity data into all 6 files.
Got it. One last question, I'm a bit nervous because I don't want to mess up a cal file.

Did you use a text editor like word pad to add the file?

Pass me a paddle buddy cause I'm in the same boat with you I have the file, I just dont know how to add it, Thanks..

I did it, when you hit, file save as, then hit the drop down box and save it as a text file, that worked for me. REW said something when I tried to load it but it still loaded. Good luck... I could not get this file and the 0 degrees file to load at the same time though..

Save it to your desktop, then open REW and you can load it..

Re: MiniDSP UMIK-1 Microphone

REW will accept FRD, TXT files. You can just load the file that Cross Spectrum produce.

Best thing to do is make a copy/s then there if a mistake is made you have spares quickly.

From the original (MiniDSP) UMIK file, copy the first line (SN + Sens Factor)

Insert a row in the Cross Spectrum UMIK file then paste

File > Save

Done

Thank you sir! While it seems I have set my windows machine to open the cal files with word pad it seems they are still labeled as .FRD files.

Sounds like either way it will not be an issue. Again, thanks guys. I will post results, but it may be a bit.

Even if you somehow mess up the original file, I have copies of the cal files I produce, so just email the mic serial number and I can send you the original cal files.

Maybe I didn't get it right, Sorry. Phillips, or anybody for that matter, could you post some screen shots of the process when you have the time. It's not letting me save anything when trying to copy & paste from the "Sens Factor =-5.929dB, SERNO: 7000896". This is the folder I saved to my desktop with original cal files.

"Sens Factor =-5.929dB, SERNO: 7000896"

10.054 -6.214461668
10.179 -6.041088351
10.306 -5.870899851
10.434 -5.703954414
10.564 -5.54013152

These are the first few lines of the files they have for my mic, above. Sorry I'm so computer illiterate.

I keep getting different floor levels when plugging min my mic, without changing the level input in Windows. Sometimes it will be ~40, others 9, and others in the 15s. Is there something wrong with my mic that the floor level keeps changing?

Unless the floor level is ~40 I can't calibrate the SPL meter in REW without having to set the volume so high that REW tells me I'm clipping. Lately I've just been skipping the calibration and setting the AVR at -10 and input level at 25 to keep the DB level consistent in my subwoofer FR testing. However I would like to have an accurate SPL reading that is identical every time (for identical graphs, etc), via the SPL calibration tool.
Sorry for not responding to your email about this (it's been a rough couple of days, we had to put out dog to sleep on Friday and things have gone downhill since). I haven't looked into noise floor issues that closely with the UMIK-1 but on first glance that does sound a bit unusual, although perhaps others can speak to their experience. The first question I would ask: is there something on your USB bus or something running in the background of your machine (anti-virus, etc) that correlates with the noise floor irregularities?
