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.

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?
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.

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".
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...
