mess with the frequencies but it can't be that simple.
It is that simple though, and the sharpness of the curve is measured in decibels per octave...
So like, If you have some evenly leveled, true white noise, and set an EQ up to cut everything above 20 hz by 12 db per octave... 40 hz will now be 12db quieter then 20hz is, 80hz will be 24db quieter then 20, 160 will be 48db quieter, ect, ect.
The curve is consistent and pretty self explanatory once someone explains it like that, any series of changes/boosts/cuts can be represented by addition and subtract in db per octave...
Well, thats how parametric graphic eq's work, linear phase stuff is mind blowingly complicated.
