Thanks. I find REW defaults confusing. I am not clear on how to interpret this waterfall graph. It looks like the decay times are lower for higher frequencies. What is bad here and what is good? Given the flutter and echo issues in my basement, I would have expected the mid to high frequencies to have a long decay time. Perhaps they do, but not as much relative to the lower frequencies?
I am getting some acoustic panels next week for the back wall and I am hoping to do a before/after measurement so it would be good to understand what I am measuring.
REW documentation is a bit too advanced for me at this point. I would prefer a simpler step-by-step for dummies that may not get me close to 100% but if it improves things noticeably, that would be a good step forward without spending hundreds of hours learning this stuff.
Also, how and where are you taking this measurement?
Using a UMIK-1 mic + REW on my laptop. Mic is placed at the listening position pointed up with the corresponding 90 deg calibration file loaded. The only reason I am pointing it up is because I haven't yet found a way to point it forward without it tipping over at the place i am setting it. I am hoping this won't make a big difference.
Meanwhile, the Integra processor has a bi-amp mode, so I connected my REL sub to one of amp/speaker outputs (set to full range) used for biamping, set the crossover to around 50 Hz and switched the Rythmiks to mid-bass (50 Hz - 250 Hz). With this, I am finally getting the dynamics I was hoping for!
