I'm finding the "this is a horrible idea" responses amusing. I don't know if there's something fundamentally different about the way this project works versus Dirac/XT32 or if the naysayers aren't familiar with it. Or maybe there's an anti-room correction sect of audiophiles that have remained hidden to me.
Not 'fundamentally', but using one single point would probably be the main issue. Move the microphone 5cm and the response measured is going to be different. Dirac and manual methods with REW use multiple points and/or just moving the microphone around.
