I'll try to explain with my awful english.
What you are searching simply can't exist:
You basically are searching for a "magic" tool to eq various tracks automatically. For this task you need a "reference" eq, a sort of "perfect ideal" response curve of a "perfect ideal" well balanced track.
But in the real world, if you analyze some tracks very well mastered by experts like Bob Katz (it's only an example) you'll notice that these tracks don't have the same spectral frequencies.
Maybe you are able to equalize two tracks of the same genre (and so same instruments), for example you can try with the izotope mastering plugin to capture the response of an AC/DC track and apply it to a Van Halen track (still I doubt the good result).
But you'll obtain disastrous results if you use that curve to equalize a Funk or Hip Hop track.
The correct equalization of the sources simply requires the human ear and intelligence to be accomplished.
I understand that what I'm trying could be near impossible.
What I'd like to know, is some understanding of how VL is doing this, because as an average listener this plugin makes miracles to some tracks.
I perfectly understand that many tracks are mastered just the way they should be, but I think it would be possible from a wide range of mainstream music over the last few decades to detect which could simply need a little boost in the lower and upper bands.
I would assume this is actually why VL is using only 4 bands, because utilizing more bands could result in a weird curve, boosting instruments in the middle band which should just have left a flat curve.
The only thing I would need this for is a little help giving me an idea of how the spectrum is for all my files, instead of just trying every track manually.
