Finished a prototype with the audio and canvas feature in HTML5. It is quite a sad thing that no single audio format can work cross browsers. HTML5 Doctor had a table showing the supported audio format from different browsers.

In the prototype I implemented the box filter documented out at Gamasutra. The blur function is applied to 6 canvas at every 100ms. Just chrome can run it smoothly….Maybe Firefox 4 can do that too, but I didn’t test it on FF4, also the mp3 may not be able to play on it…The link to the prototype (Google Chrome Only).

Screen shot with the audio mixer. Let’s play~
