Visualising data from <audio> on <canvas>

Experiments to see how data can be pulled out of an HTML audio tag and rendered/visualised using canvas.

Requires FireFox 4 beta. Other browsers will eventually catch up. I believe that there's a patched webkit version which will run this, but I'm not sure where to find it.

Read a blog post about this.
