@audio/dynamics-ducker

import ducker from '@audio/dynamics-ducker'

External-sidechain compressor. Main signal's gain tracks the level of a separate side signal.

import ducker from '@audio/dynamics-ducker'

// batch
let podcast = ducker(music, voice, { threshold: -30, range: -12 })

// streaming — callable takes (main, side); call with no args to flush
let duck = ducker({ threshold: -30, range: -15 })
let out1 = duck(musicBlock1, voiceBlock1)
let out2 = duck(musicBlock2, voiceBlock2)
let tail = duck()

Use when: music-under-voice podcasts, dialogue ducking, sidechain-pumped mixes.
Not for: sidechain from the same signal — use compressor.
