WIKI

npm install sparkle-motion

USE

window.AudioContext = window.AudioContext || window.webkitAudioContext
var ac = new AudioContext()
var sparkle = require('sparkle-motion')(ac)
sparkle.connect(ac.destination)

// set the frequency/ADSR
sparkle.update({midiNote: 72, attack: 0.3, decay: 0.1, sustain: 0.3, release: 0.5, peak: 0.3, mid: 0.1, end: 0.000001, lfoL: 0.3, lfoR: 0.6})
// and trigger it!
sparkle.start(ac.currentTime)


// destroy the oscillators completely. u probably would only wanna do this for garbage collection porpoises.
sparkle.stop(ac.currentTime)


// this will return an object containing all the nodes in the sparkle-motion audioGraph, for closer-to-the-metal manipulation than the update/start methods provide.
sparkle.nodes()
# DEVELOPMENT

npm install npm run test # should pass! Yay!

# HEAR THE MAGIC!

- `npm run serve` boot a webserver at port 3000
- `npm run build` build demo.js to a bundle. Run this after making any changes to hear updates (or add [watchify](https://github.com/wham-js/web-audio-advent-calendar/blob/master/package.json#L8), i wanted to keep things "light")
- open `http://localhost:3000/` in a web browser and hear the magic (hopefully)
