Here is a super simple example that I am trying to run on an iphone in chrome. Other web audio API examples like this one http://alxgbsn.co.uk/wavepad/ work, but not mine :(
<!DOCTYPE html>
<html>
<head>

</head>
<body>
<script>
var audioContext, osc
audioContext = new (window.AudioContext || window.webkitAudioContext);
osc = audioContext.createOscillator()
osc.connect(audioContext.destination)
if (osc.noteOn) osc.start = osc.noteOn
osc.start(0)
osc.frequency.value = 440
</script>
</body>
</html>
Any idea what's wrong?
EDIT
To summarize the answer :
iOS will only let you start playing sound with the Web Audio API as a result of a user action.
Try putting that code inside of some kind of event handler.
var elem = document.getElementById('play'),
audioContext = new (window.AudioContext || window.webkitAudioContext),
osc = audioContext.createOscillator();
osc.connect(audioContext.destination);
if (osc.noteOn) osc.start = osc.noteOn
osc.frequency.value = 440;
play.addEventListener('click', function() {
osc.start(0);
}, false);
