comb

Hi guys - I recently started using REW to analyze my HT (living) room. I ran tests of the left and right front speakers individually, and the results indicate significant comb filtering from roughly 1k on up. On the left wall of the room there's a large window, so an absorber panel isn't an...

Any thoughts on why more sweeps would give rise to large comb-filter like effects? In the attached png, the flat(er) curve shows a single sweep, and the wacky curves show 2,4 and 8 sweeps. Exactly the same measurements otherwise. I can't imagine that the first 10 second sweep is having such a...

Is this comb filtering, or something else? Seems too noisy to be room modes. I realize that the level is low, I think that the SPL is mis-calibrated (mostly due to a lower battery in my RS db meter). Using line input on a laptop, calibration file for EMM-6 mic and I've done the soundcard cal...

Can anybody please evaluate the comb filter of the SC-25/27 with a screenshot of the Snell & Wilcox 2 test pattern from a composite LD signal for me please? I an considering this AVR and this is a screening criteria for me.

I've attached a picture of my 12x17 room (with tons of 703!) and my left and right channel REW results. Any advice on how to treat (or whether to worry about) my dramatic HF comb filtering would make my day! emad
