@audio/dynamics-envelope

Branching one-pole envelope follower. Returns a stateful per-sample detector

npm install @audio/dynamics-envelope

import envelope from '@audio/dynamics-envelope'

Every processor except softclip is built on this: a branching one-pole follower with separate attack/release time constants, peak or RMS detection.

import { envelope } from '@audio/dynamics'

let follow = envelope({ attack: 5, release: 100, detector: 'peak' })
let level = []
for (let x of samples) level.push(follow(x))

| Param | Default | | |---|---|---| | sampleRate | 44100 | — | | attack | 5 | ms | | release | 50 | ms | | detector | 'peak' | 'peak' or 'rms' | | rmsWindow | 256 | samples, for RMS detector |
