Ducking and Sidechain Compression: The Decisions That Matter
Lowering one sound automatically when another plays, most often music dipping under narration or dialogue.
Tomas Lindqvist
At a glance
- Sidechain a compressor responds to a different signal than the one it controls
- Auto ducking Premiere Pro's Essential Sound panel can duck music under dialogue
- Release time controls how quickly music returns
- Pumping fast, deep ducking can sound unnatural
Why it matters
Why it matters: Ducking keeps speech clear without manual volume rides, but poorly set ducking pumps audibly and distracts listeners.
Best practice
- Duck music by a few decibels rather than muting it
- Set release times to avoid pumping
- Check ducking around pauses in speech
- Adjust music EQ to leave space for voices
- Automate by hand where auto ducking fails
Common pitfalls
Watch out for:
- Music that swells between every phrase
- Ducking so deep the music vanishes
- Relying on ducking instead of a good mix
- Ignoring how ducking sounds on phones
When to call in a specialist
Bottom line Bring in help when narration fights with music across a series.
