Ok ok I do need to ask, regarding your 16 steps I'm more in the 2nd stage of "You have a good headphone setup you are relatively satisfied with in overall signature but would like to improve its technical abilities (especially if you want smoother highs): listen to your headphones through Sinegen and smooth out its frequency response (especially in the treble), then create your equal loudness contour from your EQed headphones"
so I just wanted to ask is the dragging the point to -20db still applicable?
Edit: Actually I'm using a mac, I was doing your method on a PC to get a feel on what I am supposed to do, now that I have understood a bit I am trying to transfer the principles I learned on the PC onto a Mac with Soundflower and AU Lab. I guess I am now stuck at the making equalise loudness like in post

As you can see in the bottom I make an example of how the Q function (that's what it's called in AU Lab) can be made wider. I was just wondering is it possible to get the true equal loudness curve like demonstrated in Electri-Q or is it ok to just leave like as it is. I would imagine if I leave it as it is at some frequencies in between it would get oddly uneven in terms of loudness :|
