2.1.34. Sidechain mode

---

The sidechain mode combo-box allows you to choose how Loudness Leveler uses the sidechain input.

• Disabled ignores the sidechain input entirely.
• Engage activates leveling only when the sidechain signal exceeds the sidechain threshold.
• Disengage deactivates leveling when the sidechain signal exceeds the sidechain threshold.
• Direct uses the sidechain signal’s loudness directly to drive leveler gain, bypassing the normal source measurement.
• Engage Trg uses the primary target loudness and target tolerance above the sidechain threshold, then switches to secondary loudness and secondary tolerance below it.
• Disengage Trg uses the primary target loudness and target tolerance below the sidechain threshold, then switches to secondary loudness and secondary tolerance above it.

The sidechain threshold and sidechain knee controls are only enabled for Engage, Disengage, Engage Trg, and Disengage Trg modes.
