I use the equalizers in Peak.
I'm really not arguing audibility. I don't know why it keeps coming back to that. My point is that the top octave isn't a sliver of sound that makes a whole lot of difference to music compared to the rest of the audible range.
If I was EQing, and a core frequency band was out by 2 dB, that would bother me much more than the top octave being out by 6 dB. *Relative importance*"
"I use the equalizers in Peak."
Like I said, that's not enough description for a valid discussion. We need to know Q (bandwidth), Gain/Loss, and center frequency.

Not sure what you mean "core frequencies", probably "important ones"? But my point is if you EQ down 20KHz with your peak/dip, you can, and likely will, affect 10KHz as well. It's not that the 20KHz matters all that much, it's what effect that mechanism has on the rest of the spectrum. In my example a 6dB drop at 20KHz would result in 2.4dB loss at 10KHz. I guess if you consider 10KHz a "core frequency", then that might bother you.
