Audio Ducking
Audio Ducking
What is it?
Ducking is the automatic lowering of one sound when another speaks — almost always: music drops when a voice begins, and rises back in the pauses. The background "ducks" under the foreground. It's the technique behind every radio DJ's seamless talk-over-music, every podcast's bed that breathes around the narration, every stream where the playlist never fights the host.
Practical example
Listen to morning radio: music plays full; the DJ opens the mic — the song instantly settles to a cushion beneath the voice; the DJ finishes — the song swells back. No hand touched a fader: a ducker watches the mic channel and automatically presses the music down whenever voice is present. The streamer's version is identical: background playlist at comfortable volume, and every time they speak, the music politely steps back — the show sounds mixed even though nobody is mixing.
Key things to know (non-technical)
- The parameters that make it feel natural: how far the music drops, how fast it ducks (quick), and how slowly it recovers (gentle — instant recovery sounds like pumping).
- It's the automation of a radio craft: what a board operator once rode by hand, now a sidechain rule.
- Beyond music: the same mechanism ducks game audio under commentary, video-clip sound under the host's interjections — any background under any foreground.
- Without it, the two bad options are music too quiet to matter or music wrestling the voice — ducking is why you can have both presence and clarity.
In Tupic Live
A one-toggle ducking feature — "lower music when I talk" — gives every Tupic Live creator the radio-grade mix automatically: background beds from the music library that breathe around the host's voice, with sensible defaults hiding the parameters entirely.
