Sidechain compression uses one signal to trigger gain reduction on another.
In sidechain compression, the compressor listens to a detector input that may be different from the audio being turned down.
A kick can duck a bass, a vocal can clear space in a pad, or a filtered detector can make compression respond less to low-end weight.
Fast settings can create obvious pumping. Slower settings can feel smoother but may not clear enough space for the lead sound.
The right timing depends on groove, arrangement, and whether the effect should be invisible or audible.
Soloing the compressed track can make sidechain moves seem extreme or too subtle. Check gain reduction while the full mix plays.
