@earcon/engine-tone

Tone.js engine for earcon: 28 synthesized presets (sonar, parking sensor, Geiger counter, heartbeat, countdown, hi-lo siren, red alert, stall warning, missile lock-on, pulse oximeter, lane departure, foghorn, kettle, ticking clock; bell, register, coin, knock, all clear, buzzer, chime, SOS, gong, glass break, power down, squelch, water drop, latch click), per-monitor buses with pan and volume, and fromSpec (subpath @earcon/engine-tone/from-spec), which turns a JSON SynthSpec into a sound. tone is a peer dependency; the main entry imports it lazily inside unlock(), while the from-spec subpath imports it statically.

import { createToneEngine } from '@earcon/engine-tone'
const engine = createToneEngine({ masterVolumeDb: -6 })
button.onclick = () => engine.unlock()
