Nothing wrong with that. The home stereo manufacturers have been doing it for years using pink noise and a little mic to help customers eq the setup for their home listening space.

You find the deficiency and boost those freqs until it is even..

the big difference is that the pink noise gen as a source is 100% consistent on all frequencies, but your music source will not be... the amplitude of the frequencies will vary because music is inherently inconsistent.

In other words, how much you choose to even the amplitude across the spectrum will be subjective... like anything else with music / sound re-production.

I'd say pick some areas that look unnaturally dark and start there... but, a couple things to keep in mind:

The lower frequencies will always show more energy (amplitude), as it takes more to produce them. You should expect to see a natural fade from 0Hz to 20,000Hz, in amplitude - with the real drops coming at about 5-6k, then 10k, then again around 15k... don't try to get the same amplitude at 8khz as you have at 75Hz.. that will make it sound unnatural.

And as always... less is more. Don't do any more than you must.. your ears fatigue after just a few minutes of screwing with it. Best to listen, note BAD places, make an adjustment and STOP.. until later.. then repeat.

Less is more...
