John Resig's Class-Object has some simple inheritance without the (very verbose) prototype stuff. It's the basis of my engine: http://ejohn.org/blog/simple-javascript-inheritance/ http://ejohn.org/blog/simple-javascript-inheritance/ I used the Audio API's canPlayType() to decide whether to use mp3 or ogg.
