Audio tag

So what's the "materiality" of digital audio in the browser?

Audio (HTML tag)

A Script (Performance)

The Audio Tag

When asked to "load":
    Say: "loaded" and then a few seconds later "durationchange"
When asked your "currentTime":
   Report the number you're standing closest to.
When asked to set your "currentTime":
   Move to the number requested
When asked to "play":
    start moving towards higher numbers
When moving and you cross a new number:
    Say: "timeupdate"

Callback 1

When AUDIO says "durationchange":
    Tell AUDIO: "Set currentTime to 60" and then (after a few seconds) "play"

Callback 2

When AUDIO says "timeupdate":
    Ask AUDIO: What is your "currentTime"
    If it's response is 63 or bigger:
        Tell AUDIO: "pause"

Javascript

Javascript version of the above. 

$(audio).bind("durationchange", function () {
    audio.currentTime = 60;
    audio.play();
}).bind("timeupdate", function () {
    if (audio.currentTime >= 63) {
        audio.pause();
    }
});

AudioLooper

Loop

<script src="http://code.jquery.com/jquery-1.9.1.min.js" > </script>

<audio controls>
	<source src="http://wsdownload.bbc.co.uk/worldservice/css/96mp3/latest/bbcnewssummary.mp3">
	<source src="http://pzwart3.wdka.hro.nl/~mmurtaugh/bbcnewssummary.ogg">
</audio>

<script> 
$("audio").bind("durationchange", 
	function () {
		$("audio").get(0).currentTime = 30
		$("audio").get(0).play()
		console.log($("audio").get(0).duration)
	}
)

$("audio").bind("timeupdate", 
	function () {
		console.log(this.currentTime)
		if (this.currentTime >= 33){
				//this.currentTime = 60
				$(this).trigger("durationchange")
		}
	}
)

</script>

recursive exercise using jQuery+ CSS

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script> 

<style type="text/css">

div.box {
padding:10px;
		background:red;
		border:1px dashed black;
		color:white;
		width: 1000px;

      }

  			}
