+++ on the fabfilter pro q
but for analyzing before and for cleaning up after coloring. i usually have it open while coloring too, to see whats happening, making clean up that much faster.
just to give you an extra thing to think about
: dont f with an already nice tone. i think about tone as a sounds complete harmonic spectrum. and by that i mean its got its fundamental resonance supported by between 5 and 7 octaves of lesser resonances. go past that, or start supporting elements that arent in harmony and youll take away from the tone. which of course is what youre after when youre changing tone.
so with an eq like pro-q check which harmonics are missing and learn how to target specific bands with these coloring sticks. or, see which to remove, and then go about creating new harmonics instead of trying to fight the existing ones.
a lot of music lately is over saturated, randomly, and unnecessarily. leading to ear fatigue for listeners, and more laziness for us.

its nice to have a broad band effect on stuff, since that tends to get things gluing easier, but were forgetting how that translates to our master channel, where the space for resonances is limited. its another less is more situation. so choose your peaks wisely! alot of people rely on a songs key to figure out placement, but notes arent very specific, so stick to math math. also, dont get too carried away! make all final judgement with your ears and heart, if something need an extra spike or two, do it. if it sounds fine, leave it alone.
you can easily spend a month on something that should have taken an hour, which applies to alot of things audio, and why sharing knowledge is life saving. i dont know if this was knowledge, i think alot of people think about thisand take care. theres also what i call "pad mixers". they kinda make clouds out of sounds and keep thier fingers crossed as a bunch of compressors hold things down. those guys tend to rely on partying for work. i have busier templates...
