File-> save FRD
Then in Added Curves, Add the FRD files for the curves you want to show. (Non-live curves for frequency response are called "Added Curves" in Omnimic).

Ok, mtg, I'm impressed. Nice frequency response on those!

Why can't the DIYSG forum at Erich's site be the "subforum"? It's just another link to stick on your bookmarks list... And won't clog up AVS.

Probably, but I haven't noticed any issue so far. Probably just some fiber at both ends would be enough to kill any resonances that might occur.

Windows8 screws up recording levels with usb mics, no idea why they still haven't fixed it. The workaround (at least with Omnimic) is to run the measurement app in "XPSP3 mode". If you right-click...

Erich,

Can we get some cabinets milled out of a solid aluminum block? That's becoming a thing now in the high end market!
