Branching one-pole envelope follower. Returns a stateful per-sample detector
import { envelope } from '@audio/dynamics-envelope'
The common detector for the envelope-driven processors is a branching one-pole follower with separate attack/release time constants, peak or RMS detection.
import { envelope } from '@audio/dynamics-envelope'
let follow = envelope({ attack: 5, release: 100, detector: 'peak' })
let level = []
for (let x of samples) level.push(follow(x))
