REW and Qudelix 5K

[MKreroo]

Hi, I have recently done a measurement with Umik-1 and REW, and have generated an EQ. However when inputted into the 5K PEQ the overall curve seems flipped from the Filter graph in REW.
Should I be inversing the gain values or this is the intended result?

On another note, the response here is done with Psy smoothing, would 1/6 or Var be better suited for NF use? Response with those smoothing are much more spikey.

Thanks

No, that looks correct.

Just slightly confusing how REW displays filters.

Best to use the Moving Microphone Method without any additional smoothing.

You get graphs like this:


Very detailed, perfectly readable, and without the issues of single-point sweeps.

Good to know it's REW that display the filters inverted.
This measurement was indeed taken with MMM, around 60 averages surrounding the MLP with 1/48 smoothing (smoothing was advised on another thread here)

I was under the impression that the un-smoothed graph would have lots of narrow peak/dips and thus not good for making EQ.
Without any additional smoothing, response >100hz can be EQ quite smoothly but <100hz remain very uneven (room mode?)

It seems the individual max boost needs to be higher, though currently at 6 I thought is already fairly high.

Max boost won't help much for room modes as physically, you cannot bring up bass nulls using EQ.

You can compare to the graph I posted above for a sensible PEQ approach to room correction.
