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.
Ajaxian has the full story about how it all came about.
