Biquad filter in HTML5

This is my first attempt at trying out the new web technologies.

The  Biquad Filter is implemented in JavaScript and using the Mozilla Audio API for accessing the audio.  The frequency response is also calculated in JS and plotted using Processing.js and JQuery UI to control the parameters.

You can try it out here.

Remember that you need a firefox build that has the audio API patch applied, you can find them here.
