REW and ARC Genesis results differ a lot. Frustrating me. Help?

Can you use custom target curves in ARC? I wrote that script but I have never used ARC in my life

Nothing like DIRAC you can modify crossover, gain/cut, and change a visual target that it tried to achieve.You can modify the heck out of what order crossovers and pick a freq to boost.

1.10.5 is now an official release, as usual, they give a few things fixed and say improvements Have you ever worked with anyone on your ARC file? There are a few people that tweak other's files for them (I do) but always remember ARC is showing a suggested target and tries to get there, REW and UMIK are much more accurate. I have asked Anthem several times for a calibration file with no luck. Maybe someone here could show a way to make one?

Anthem does not give any information at all about the mics and how they calibrate or verify them, it is frustrating. Unfortunately I don't think we'd be able to make a calibration file without a professional setup to calibrate the mic.

You can use the script above and drop your ARC measurements on REW. Place an Umik in the same direction as close as possible (the tips) to the ARC mic and repeat the measurements with REW (making sure you have uploaded Umik calibration file). You can |A| / |B| divide the responses in REW and can create your own ARC mic calibration file. It will be as accurate as your Umik in the bass region and for up to 5-6kHz depending on how close your mic tips were during the two sets of measurements.

I would suggest using DIrac's own Harman curves (Dirac Harman +4, +6, etc.) with Dirac. They are specially adjusted Harman curves for the frequency dependent windowing Dirac applies to responses before filtering.

Yes but it wouldn't be truly calibrated, it would just be close to matching the UMIK-1, which itself isn't perfect. That being said, having the ARC mic info wouldn't even be that useful because I can't change the mic measurement responses in Genesis : (
