This is simply to make using the HTML5 audio tag a little bit easier. It abstracts away some of the cruft of creating an audio player and specifically, makes it easy to have more than one (or many!) audio players on a single page.
Make the .js .png .css files reachable from your web page and set up an audio player like this:
<div id=1 class='player'></div>
Call this javascript function on document ready
build_player (1, 'some_file.wav', 'some_file.png', 20, 600, 100);
The signature of build_player is
build_player (id_of_player_div, path_to_wav_file, path_to_png_file,
height_of_controls, width_of_player, height_of_player)
See http://robtandy.github.com/SimpleHTML5AudioPlayer/ for an example several players on a page formatted differently
