not increasing. very stable. the volume is pretty low. 3 sec cooldown left from previous measurements of small midranges.

I get significantly different THD numbers and harmonic levels when I measure in RTA vs Stepped Sine. Stepped Sine vs Sine Sweep give me roughly the same results. Settings seems to be the same - you can see on screenshots.

perfect. thanks!

Hello there. I can't access Google Drive folder from REW in MacOS. On windows seems to work fine. I just don't see the folder where it supposed to be. I prefer to save all measurements in Drive, but how do i do it?.. Am i missing something or is there some workaround?.. Also i have some...

hm. did not happen with this particular version.

also counter of measurements left (10/28) does not change.

i guess not related issue... i've marked "try smaller steps" and "stop at 1%". and it went well... until it got stuck in some kind of loop testing at the same level over and over again. i've looked at DBFS level - it did not change for quite a few measurement rounds. i had to manually stop it...

seems to work now...

works magic! thanks.

sure.

by the way - it is totally expected for THD to grow in the end of the measurement. i want it to be on the chart up to 10+%.

THD vs Level Stepped sine measurement is "not saved", it is empty. Check out the screenshots attached. Empty distortion tab and one dot on the SPL and phase tab. Looks like it happens when i have a spike in the distortion in the end of the measurement. No digital clipping yet. If i lower the...

got it. i though with big FFT we suppose to get better precision, not dramatically less :)) i guess i am missing something :)

ok. how do i do that?

it helped with single sine, but... :) it's always some "but..." :)) similar problem with multitone. 512k fft - no problem, 1m - it goes wild.
