I thought about doing this. Haven't tried it yet. I was thinking that it would be difficult, upon examining the recorded measurements, to identify which one went with which position. I suppose I'd have to keep track of it on a diagram. Each measurement would have to default to the ETC graph for...

I'm working with a lot of people who are currently playing reflection detective and something like this would save so much time.

I figured, but what if those sweeps were relatively short - like 256k - and repeating? REW's generator can already do that. It can also be told at what frequency to start and stop the sweep for the sake of what is being done. All that's needed is a method to read these sweeps in a real-time...

I am very conscious of what the RTA is. My question has to do not with the standard use of tracking SPL response, but with the idea of tracking reflections (i.e. the ETC graph) in real time to make hunting for room treatment points on walls faster than the standard measure-move a...

I seem to recall that there was a way to check for phase issues between channels (where they are out of phase with each other) from the LP by comparing some of the averages together. I can't remember exactly what to do to get the result I want, though. I do know that the mic remains stationary...

That method there produces some fine minimum phase filters using inversion. It's the best I have been able to come up with, plus it's relatively simple to execute.

If you make correction filters from vector average responses instead of dB or RMS responses, there will always be differences because the vector average is not a true representation of magnitude like a dB or RMS average is.

My response featured a typo, which I have fixed. It said that FDW will ignore the dips. What I meant to say was that the FDW will not ignore the dips. We don't want those dips included in the FDW calculations. Acourate's psychoacoustic treatment removes them prior to applying FDW. The only way...

The problem with FDW in Room EQ Wizard is that it is applied without a psychoacoustic treatment ahead of it. This may be appropriate in certain situations but if the goal is to generate perceptually accurate acoustic correction, you have to apply a psychoacoustic treatment to the response ahead...

Typically I avoid boosting anything in the filter. Try lowering your target or adding more EQ bands. Either that or, if you use a computer to run audio, follow my guide. You can add a small bump (low shelf) in the target if you'd like. https://nverxion.wixsite.com/meridiansoundworks/drc-rew

No difference at all? That's strange. What does your system configuration look like?

I think the spectrograms look "worse" because the range is shifting based on the highest SPL in the measurement. It looks like the whole thing is being shifted up (toward the screen) as the bass peaks are attenuated with the filter. Notice how the scale on the right changes when you switch...

Interesting. With the setup I use (the one I typed up in the guide) I haven't needed to use that feature. Everything works great. I'll look into this, though. Nice to know there's another option hidden in there.

It looks like your traps are mostly effective from 160Hz and up. They aren't doing much below that. Either they aren't thick enough, they aren't in the right places, or there isn't a large enough air gap behind them. Not sure what the case is. There is a large reflection in the ETC graph around...

You should look into using Voicemeeter (either Banana or Potato) and a VST plugin host like Hang Loose to run your system audio. I have written a guide demonstrating how to configure a system with these tools. https://nverxion.wixsite.com/meridiansoundworks/resources/systemwideasioforwindows
