    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...

    I may have just missed the button. Is it possible to get the live difference between the reference and the mic feed on the RTA?

    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 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 am in charge of all the EQ at a Subwoofer GTG on October 22. We will have 13 different subwoofer setups for the day. All the subwoofers will be in a garage and moved down to the basement theater room for their individual EQ, measurements, and listening. With this many subwoofer groups I need...

    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...

    Hi again Sorry for all the questions! I'm sure that sometimes when I re-open a set of graphs the colours of the traces change. I just wondered whether they should be saved or not? For example, on one set of measurements yesterday I changed all the trace colours individually so that the...

    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...
