    atm you can copy a trace using (A+B)/2 but the copied measurement is left with ref time of t=0 no matter where the original traces are. It would be nice if this were set automatically and/or an explicit copy option were added that avoided the need to use trace arithmetic at all. On a related...

    Hi all, I have a question: what is the difference between the trace arithmetic function A+B and the button at the bottom left of the graphic named average the response ? The graphs are very similar but with different values, is it a geometrical average ? Also, what is the difference between A+B...

    This might be a stupid question but I'll ask anyway. REW lets you sum 2 traces but say I want to sum multiple sources (e.g. >2 subs), does this work correctly in REW? i.e. does A + B + C = (A + B) + C when it comes to summing measured responses?

    Hi all how do i do to merge/add/divide measurements in REW ? (i want to average 4 impulse responses ) thanks

    Would it be possible to include arithmetic inversion (B = 1 / A) in the future REW versions?

    Hi I am trying to make a calibtration file for REW. With the facility Trace Arithmetic how would i do this.? i have tried to do this with the different calculations then import that file, but it doesnt work. I have attached the txt files for both mics, both named. Your help would be...

    I had measured the woofer and mid driver response separately and combined them using trace arithmetic (A+B) and am puzzled by the results. see attached screen shot. at freq = 212Hz, amplitudes from the graph are: A=125.1, B=125.5 A+B=98.7db From my calculation...

    I am running REW V5 on a Vista laptop. Everything seems to work fine - testing line level crossover signal from my receiver. I can't find the arithmetic tab though. I wanted to sum 2 curves, and after looking over the help manual, it looks like it should be an option under "Overlays". When I...

    Hi All, Is it possible to run EQ filters synthesis for calculated arithmetic traces? I see no restrictions about this in Help file, I tried to do this but no luck. Steps to reproduce: - make two measures (dummy ones), call it "1" and "2". - make trace "3" by generating trace in "Trace...
