@audio/dynamics-gate

Noise gate with hold-then-close logic and smoothed gain transitions

npm install @audio/dynamics-gate

import gate from '@audio/dynamics-gate'

Noise gate with hysteresis, hold-then-close logic and look-ahead. Opens above threshold, closes only below closeThreshold (hysteresis prevents chatter around a single threshold); below it, signal is attenuated by range dB. A hold timer keeps the gate open after a drop-out; attack/release smooth the gain transitions. lookahead runs detection ahead of emission so the gate is already opening when a transient reaches the output — batch calls stay sample-aligned (no silence prefix, no dropped tail); block hosts get the delay declared as atom latency.

import { gate } from '@audio/dynamics'

gate(data, { threshold: -40 })
gate(data, { threshold: -35, range: -80, hold: 20, attack: 1, release: 150, lookahead: 5 })

| Param | Default | | |---|---|---| | threshold | -40 | dB, open above | | closeThreshold | threshold − 6 | dB, close below (hysteresis) | | range | -60 | dB attenuation when closed | | hold | 10 | ms | | attack | 0.1 | ms (opening) | | release | 100 | ms (closing) | | lookahead | 0 | ms, detection leads emission |

Use when: drum mics, voice dialogue with ambient noise, removing hiss between phrases. Not for: subtle low-level reduction — use expander.
