Wavy Jones

Need a simple way of showing what your audio looks like in real time? Already have a project that uses the Web Audio API? Wavy Jones is just the thing.

You can just connect Wavy Jones just as you would any other Audio Node, with the side-effect of having a nice oscilloscope that you can control the look of.

The best way to start using Wavy Jones is to grab it from GitHub

How to use

Wavy Jones relies on a couple of things, namely:

Your project must use the Web Audio API You know who Greg Evigan is

Step 1. SRC-ya!

Firsty, you'll need to reference Wavy Jones after downloading it by doing something like this:

<script src="/wavy-jones.js"></script>

Step 2. Make space!

You'll want somewhere to show your oscillator, so just create and empty div and give it an id like so:

<div id="oscilloscope"></div>

Don't forget get to give it a height and width!

<style> #oscilloscope { width: 400px; height: 200px; } </style>

Step 3. Gonna get myself connected

Wavy Jones is basically a normal Audio Analyser node wearing a sparkly jacket. This means you can connect it up just like you would any other audio node.

var context = new AudioContext(), sineWave = context.createOscillator(), myOscilloscope = new WavyJones(context, 'oscilloscope'); sineWave.connect(myOscilloscope); myOscilloscope.connect(context.destination); sineWave.start(0);

Ch-ch-ch-ch-changes

It's easy to customise Wavy. You can change the thickness and colour of the line by doing something like this:

oscilloscope.lineColor = '#EE0000'; oscilloscope.lineThickness = 3;

Super.
