Using node.js event-based JavaScript interpreter to perform real-time audio data transfer from arecord to Chrome browser running Processing.JS. This is an example I'm putting together for my Embedded Linux Conference presentation this week. The Cloud9 IDE, audio capture and web server are all running on the BeagleBoard. Chromium can also be run on the BeagleBoard for the display, but I didn't show that in this video. Other browsers might also work.
