EQ Graph: Maximum - Average (Infinite)

What does this graph do? Why does it display at +3dB slope compared to my graph settings? In other words, pink noise displays flat with 3dB/oct slope but this one shows an upward tilt. You have to set Main Settings/Analysis/Slope to 0dB for pink noise to look flat with this one. Overall, I know what the rest of the graphs do but their '?' icon just shows the Help for the Paste function. Is this band displaying slope wrong?

So here's the reason: you take the input spectrums maximize them and average them, then subtract these too. The result - it will mitigate any slope that was in the signal! That's the point of the graph after all - to see the "deviances". Now we have +3dB slope by default, because that's how most signals and pink noise behave - they have a natural -3dB slope, so we compensate. But this graph doesn't.

So it's basically the EQ curve you'd have to apply to get 'Average (Infinite)' to look like 'Maximum'? I didn't realize it's "Maximum minus Average (Infinite)"; I thought it was a hyphen.
I don't fully understand your explanation, but I'm grateful for it anyway. The way it seems to me is you maximize 'Average (Infinite)' and 'Maximum' then you end up with positive curves for where 'Maximum' has more temporary energy. I'm not sure if that's what's happening but I think I understand that this graph, overall, shows the spectral difference between peak and average levels. What I'm less certain about is which the graph is showing: does an upward curve mean that average or maximum levels have more energy? To me it looks like it ends up showing where Maximum exceeds Average. Thanks.

Basically it's all about slope & the properties of the pink noise. To be honest, I never used this graph myself, it was one of the many FRs, which are perhaps a bit of a confusion generators only

Oh I see, thank you. Yeah, I love your software but I realize there's kind of a "soft bottom" with it. Not how you're thinking (hehe) but meaning the hard bottom is the absolute limit of the software's capability but the "soft bottom" is just my lack of complete understanding.

Hehe yeah. You know, some time ago I was kinda implementing every FR people asked for, and that's what happened
. Then I stopped and people start arguing "why don't you do that man, you suck!"
, so that's why
(among other things)
