Ducking Music Under Speech Without Killing the Vibe

What ducking is for

Ducking music under speech lowers the score whenever someone talks, then lifts it back when they stop. The goal is simple: every word stays clear while the music still sets the mood between lines.

Without ducking, you face a bad choice. Turn the music up and lose the voice, or turn it down and lose the energy. Ducking lets you keep both.

Depth and release matter most

Depth is how far the music drops. Six to ten decibels is usually enough for narration. Set it deeper and the music pumps audibly, which draws attention to the effect itself.

Release is how fast the music comes back. A slow release, around four hundred milliseconds, sounds natural. A fast one makes the mix breathe in and out like a nervous hand on the fader.

Settings to start from

• Use the dialogue as the sidechain trigger rather than a manual curve when you can.
• Start with a six decibel dip and increase only until the voice is clear.
• Set attack near ten milliseconds so the first word is never clipped.
• Set release near four hundred milliseconds to avoid pumping.
• High pass the trigger so bass does not open the duck by mistake.

Ducking should be felt as clarity, never heard as a fader moving.

When not to duck

If the music has no vocals and sits in a different frequency range from the voice, you may not need to duck at all. A quiet pad under a deep voice can coexist with no automation.

Also skip heavy ducking on musical moments where the score is the point. Let the music lead there and keep speech out of the way instead.

Key takeaways

• Duck just enough to keep every word clear.
• Keep the dip shallow to avoid pumping.
• Use a slow release for a natural feel.
• Channel the trigger from dialogue, not from the full mix.
