Mindset Shift Idea: Forget what you know about mixing.
I'm continuously learning through practice that it's kind of detrimental to focus on the ideas of what a compressor or EQ or clipper, or whatever is "supposed" to do. Compressors aren't just for taming dynamics, EQs aren't just for balancing frequencies, and so on. Instead, analyze your song. If you hear a problem, decide which tool (of the ones you own or don't) could solve that problem most effectively. For example: you have a drum kit recorded in stereo. The snare is too loud. This is a dynamic problem, right? Not really. I mean, yes, but it's best solved with an EQ. You could use a compressor or clipper to turn down the snare, and crush it while leaving the rest of the kit intact, or you could just use a parametric EQ with higher bandwidth to target the snare specifically and turn it down, maybe with a dynamic EQ sort of process so your attenuation doesn't affect the quieter kick and toms, and at the same time, use a sharper EQ to target the kick and toms and boost them. I have an example of this, but I'm not sure how to share it. I was working through Music Production 101, on the "Long Way Home" song introduced in Mixing > Dynamics in the Mix and realized the methods shown really don't work very well. Not as well as an EQ anyway. Try this with the drumkit in the song, then, maybe, after the kick, snare, toms, and hat are balanced with EQ instead, then try to target just the snare with a clipper or compressor for a much smaller amount of gain reduction (less will be required). 2 things will happen: 1. you'll notice it sounds far more natural 2. after the EQ, before you even add the compressor at all, you'll notice the drum kit starts to sound fully mixed. Not quite 100%, but 80% for sure. Another example in the same song, regarding the snare: If you want more low mid body on the snare, you could try to EQ it, yes, but it might affect the whole kit. So instead, use some parallel processing. Use a parallel track with a high and low pass filter set to isolate those low-mids (where the snare sounds loudest). Then add tube or tape saturation to give it some leveling, oomph, and fatness (I used a tube), but also provide it some gentle distortion to work as a sort of exciter, and then mix it back in, and then EQ so it fits better with the kit. Just because an EQ "is for frequencies" doesn't mean its the best tool to EQ a snare, for example. Instead, I used a tube, some gentle compression and distortion from said tube, and some parallel processing to "EQ" the snare.
