Effect of micro-setting target level when EQing - a sound practice?

So was I... The problem isn't there, however.

The 1/3 octave smoothing used in psychoacoustic smoothing in REW is just about right to avoid beginners trying to boost room mode nulls below Schroeder frequency.

You can see the non-minimum phase areas of room response by looking at the excess group delay plot. Wherever that curve is non-flat, you've got non-minimum phase problems. (ref: D'Appollito Testing Loudspeakers).

Thanks for the link. I think we are trying to achieve different goals. If the goal is to use a fully automated procedure and at the same time avoid boosting nulls, then heavy smoothing will do this. However, the price is much too high: It leaves the peaks intact. It is much better to use Var smoothing in combination with setting Individual Max Boost to 0db in the Filter Tasks panel. This will cut the peaks.

I just said that it doesn't. Humm...

I guess we'll have to agree to disagree.

And I never use "fully automated" procedures (also here). I find they all fall apart around the transition region and below (when taking measurements at the listening position--"LP"). I always edit what REW produces via its EQ facility.

Yes, I also do so and add the low Q positive gain filters manually.
