Hi folks. I am having some problems using REW, and I'm hoping maybe someone can help?
This is my first time using REW to make speaker measurements. I'm trying to splice a nearfield measurement I took with a farfield measurement, but when I use the "trace arithmetic" function, the result is that the spliced measurement cuts off at the point where my farfield measurement cuts off. Since this is really my first foray into all of this stuff, I am not super hip with all the lingo, but I limited the farfield measurement to 3ms to try to take away the influence of the first reflection, which is why it only goes down to about 350Hz. The reason the nearfield measurement only goes up to around 10KHz is because the free version of Excel Online would only let me copy a certain amount of text, and I didn't bother pasting above 10KHz because that data I don't think is important to me?
I can send more screenshots of what I have been doing on REW if the one photo I have inserted here isn't enough. Does anyone know how I can get my spliced measurement not to cutoff so high? Thank you 🙂

Try swapping the measurements? I use VituxCAD for NF summing, but in REW I got seemingly-correct result (bottom blue trace) when measurement A was gated measurement, and measurement B NF measurement. Reverse order - A NF, B gated - resulted in cut off splice (green trace).
