Mic Calibration File - Dirac Full for XMC-1

[chipless]

I recently received an XMC-1 and I've had a chance to run Dirac, but I have some questions pertaining to the mic calibration file.

Running Dirac via a Mac and I have the UMIK-1 with calibration files from Cross Spectrum Labs. All of the calibration files end with the ".frd" file extension. According to Dirac:

We support UMIK-1 calibration files, XTZ calibration files and .omm calibration files used by Dayton Audio. There is currently no clear standard on how calibration files look, when there is one we will implement support for that. If you got a microphone with another calibration file, please read the documentation on how to adapt it for use with our software.

My questions:

• Will Dirac via Mac recognize the .frd file extension? If not, which extension will it recognize?
• Is there a way to tell if the calibration file was properly applied?
• Is it possible to apply the calibration file post measurement? If so, how?

Thanks for the help! I am looking forward to posting my final impressions of the XMC-1 paired with XPA-1s and 1Ls after coming from a Marantz 8802 and ATI amps.

Have a look at emotivas mac calibration file and see what it ends with.

Do you have the full version of Dirac? If not, you can only use the Emo mic. With the full version you can use the UMIK and you can point to the cal file from within the program.

That was my original thought, and this is what I found within the installed folder. Just as an experiment, I changed the file extension of the .frd files I have to .txt and opened the XTZ file as well as the ones I edited to check for differences in formatting. I see only two differences: 1) There is a space before each line in the files I changed, and 2) each line ends with a zero digit as compared to no such extra digit in the XTZ file. Anyone have answers to my original questions given the additional info above?

Sorry, I should have clarified in the body of the post (although the title of the thread does mention it). Yes. I do have the full version, and I know how to point to the cal file within the program, but my questions still remain.

I did not have to change the files extension as sent from CS Labs. When you point to the cal file Dirac will accept it if it's sees it as a good file. They are really only text files. So if Dirac displays the chosen file in the program you're good to go.

Good to know, thanks! It seems .frd, .cal, and .txt cal file types all load properly into Dirac.
