Does there exist a way to EQ based on phase instead of amplitude?
Say your speakers and position have a problem at a frequency such that amplitude adjustments will not compensate. It would be nice to adjust the phase of a parametric band instead of amplitude.
Yep, completely possible. You'll need to read up on FIR processing. EQ APO can import FIR impulse files - you'll need something like RePhase to make those.
