The information you share with us is very useful for those who work in the music field, not only mixing, but also in recording, in my case, when I record music, karaoke styles, I always find myself with the dilemma that the tracks are of very poor quality, the editing process can improve a lot, as you mention in many tips.
The editing process is a very arduous job that can take months even on a track, it requires good mixing programs, sound and all that it implies. In my case, I have many limitations, but I do the best I can, always looking to improve.
Your techniques and teachings will surely help me a lot, as far as the program and my limited knowledge will allow me. Thank you for sharing with us valuable help material.
I've been learning all this time, but unfortunately I don't have good equipment. Example: when mixing monitor speakers are needed, but I only use headphones for 1 dollar
