It corrects specific frequencies. Or course, by your chart, it wouldn't do you a whole lot of good as they nominally only work from 1500Hz up. You look pretty flat there...sorry, wrong direction.
IDK, if I can get my room to look that flat from 50-12k, I'll be very happy.
Okay, got most of my trapping up, and I've got a couple of frequencies I'd like to tame. I've got two nulls: 514Hz dip ~8dB, 950Hz dip of ~6dB, and a 5dB spike at 1613Hz @ 60dB Pink Noise. Any advice on the best way to render these flatter? My room is quiet and sounds very good. I measured at the sweet spot. Should I build a diffuser for the nulls on the back wall? Should I just use a parametric eq to deal with those three frequencies at output (like Equalizer APO)? Should I just get used to how it sounds and deal with it?
stuff like Owens Corning 703 insulation work well enough or is it worth it to invest in acoustic foam?
