@audio/synth-lfo

Low-frequency oscillator (modulation source)

npm install @audio/synth-lfo

import lfo from '@audio/synth-lfo'

Low-frequency control-rate generator — sine/triangle/square/saw, bipolar (-1..1) or unipolar (0..1). A modulation source, not an audio-rate processor — no audio.js manifest (hosts drive param modulation directly; an LFO-as-atom would be redundant with a host's own modulation routing).

lfo(2, { type: 'triangle', unipolar: true })   // → Float32Array

| Param | Default | | |---|---|---| | freq | 2 | Hz (positional) | | duration | 1 | Seconds | | type | 'sine' | 'sine' | 'triangle' | 'square' | 'saw' | | unipolar | false | false → -1..1, true → 0..1 | | phase | 0 | Starting phase, 0..1 | | fs | 44100 | Sample rate |

Use when: rendering a modulation curve to multiply/add onto a param, offline (for a host with live modulation routing, drive the param directly instead).

Part of @audio/synth — the synth family umbrella.
