Oops, sorry.
The description of the bug at that link is:
"While trying to play the mp3 local file sytem song, there a time gap to play the song, but it works will for playing web hosted song .
var player = new Player();
player.play('file:///HRUDAYAM.MP3');
var Player = function ()
{ this.audioContext = new webkitAudioContext(); }
Player.prototype.play = function (url) {
var currentdate = new Date();
var request = new XMLHttpRequest();
request.open("GET", url, true);
request.setRequestHeader('Access-Control-Allow-Origin', '*');
request.responseType = "arraybuffer";
var audioContext = this.audioContext;
request.onload = function () {
var soundSource = audioContext.createBufferSource();
audioContext.decodeAudioData(request.response, function(buffer)
{ soundSource.buffer = buffer; }
, null);
soundSource.connect(audioContext.destination);
soundSource.start(0);
};
request.send();
}"
However, I don't believe it is restricted to mp3 files since obviously I wasn't referring to mp3 when making my post on the Tizen forums. This bug report contains a link to a thread on forums, but I'm not sure if you need an account to view: developer.tizen.org/forums/web-application-development/web-audio-api-delay-local-files
It's too long of a thread to paste the contents here, and lots of what is discussed frankly goes over my head technically. If you are unable to follow this link and would like more specific information let me know and I'll do what I can to help!
The bottom line is that I didn't get the vibe that this was going to be fixed right away. Not sure what the urgency level is in the Tizen camp.
