Thx John. Yes, of course you are right on not making a difference since cal adjustments are just additive. I was thinking the cal adjustments could change the shape or width of the skirt on the fundamental but that was a brain fart on my side.

@John Mulcahy sorry but I just wanted to make sure I understood something above. Is the aes17 or standard notch applied after or before the .cal corrections are made to the data?

Thx for the explanation @John Mulcahy

Appreciate the response. It would be interesting to characterize the effect of one notch vs the other on thd+n. No way for any closed form solution to do that though.

@John Mulcahy is there a definition of “fundamental lobe” somewhere?

Oh I stupidly forgot that the REW notch options are applied after the cal file adjustments. Thx

@John Mulcahy does it really make sense with these thd +n calculations for all audio situations. For instance when you use a notch to filter out say 1kHz then run it through REW with a cal correction? Is say a 30db reduced fundamental after the notch filter close enough to a dac’s noise...

Does the AES17 notch for calculating the strength of a fundamental tone match AP software? I read the description in REW of the 2 notch types but don’t understand how the compare to other software. I see how a 1octave wide notch might make sense at say 1kHz but a 10k wide notch when the...
