How does sidechain compression actually shape a mix?

27 Eki 05:45

I keep hearing about sidechain compression in house tracks, but I’m not entirely clear on what’s actually happening under the hood. How does the sidechain signal affect the gain reduction of the main channel, and why does it create that characteristic pumping effect? Are there best practices for setting attack and release times in a club‑oriented mix? Would love to hear your explanations and any tips you use.
