Read your guide and it states to set the gain to 81 in Win 10. Don't really know if that makes a big difference but at this point I have to try everything. Plus I have to set the sensitivity in calibration file and see if that makes any difference.
First of all, the mic sensitivity setting is not used by Dirac, although the calibration file is. The Windows audio gain setting also has no bearing--Dirac adjusts this setting to meets its needs.
You can see from the response measurement of my mains that a roll-off in the high frequencies is not unusual, especially in a highly treated room like mine. I tailor my custom target curve to follow the roll-off, rather than trying to artificially boost the high frequencies. I don't hear much, if anything, above 15KHz anyway.
