HTML5 audio tag with realtime javascript FFT visualization
Over the last couple weeks the #processing.js channel on IRC has been a buzz about David Humphrey’s experimental firefox patches which reveal live audio signal data to javascript. I was able to get a build compiled on my macbook and quickly whipped up this example in processing.js. This demo uses a FFT implemented in javascript and processes a 2048 sample buffer in realtime.

Mechanical reproduction of digitized speech on a piano
This is one of the cooler things I have scene recently and I’m kind of embarrassed I didn’t come up with it myself as it is so similar to my Spectrotune project. Over the weekend I plan on working on some code to do the same thing except instead of using a piano as an output device I will output to any MIDI compatible device. Should be fun and interesting project to replicate.
