Btw @John Mulcahy I don't think the term "Trace Arithmetic" is very good, sounds like it's about the visible trace only (like for example Trace Options). Wave or vector arithmetic sounds better ihmo.
Is the new trace arithmetic functionality a better way to create a convolution file for room correction? Obviously, you can't do any hands-on changes as you can with EQ filters, but still?
Cheers, I usually don't do automatic correction, I like to do it manually and trying to use as few filters as possible, and as you say keep the Q down. Just never noticed this behavior before.
I think I will only generate 48khz impulse response and then use that for all sample rates (I use...
Don't remember and now its gone, but did a similar correction and got a similar result (but not quite as bad). Only auto-correct from REW, and REW put a -9.6dB filter at 19897, see below for a screenshot. So its probably what you said, but with regular filters instead of notch.
As you can see...
I found the problem, its the higher sample rates that gets wrong. I did a correction from a measurement, exported if (Export filter impulse to wav) to both 44khz and 192khz. Then I imported them and looked at them
44Khz (sound correct):
192khz (sounds muffled):
I have used REW for several years, mostly for room correction. But it seems something is broken in the last versions, 5.20 beta 8:
1. I took a moving-mic RTA measurement, made correction and then measured the correction and got -6dB in the 5khz area and a wide area around it. Needless to say, it...
