Hey Folks,

We're mixing things up a bit with the next live code - Aaron Hans ( is going to show us how to pull information from HTML5 audio, and use it to power an interactive visualizer! This is going to be a visually spectacular live code you don't want to miss.

Web Audio, Waveforms and WebGL:

Being able to pull live information from HTML5 audio and use it to power an interactive visualization is powerful, fun and sometimes beautiful.

This live code will Begin by interrogating a playing sound file, and using the data to create scenes starting with a 2D waveform. After that, we'll explore weirder, more complicated visualizations including 3D particle systems with three.js (

Playing around with music like this is a rewarding way to immerse yourself in the capabilities of WebGL ( using three.js. Developers without experience with these specific technologies will quickly be able to create cool visualizations

A little about Aaron/Reverb:
