Description oao.hikaru.oao 2014-01-14 16:52:38 UTC 
Now, when use `File` to `Audio`, we should write like this,

var audio = new Audio(URL.createObjectURL(file));

but, that is redundancy, and `createObjectURL` need `revokeObjectURL` to release it's data.

Therefore, we should be writable like this,

var audio = new Audio(file);
Comment 1 Philip Jägenstedt 2014-01-14 16:58:17 UTC 
The HTMLMediaElement.srcObject suggestion in bug 23775 is relevant.

Also note that there is no Video constructor, not that it matters.

FYI, URL.createFor does not need developers to couple a URL.revokeObjectURL call with it.

Thanks.
That mean we can write like this ?

var audio = new Audio();
audio.srcObject = file;

Yes, I believe that's how it's supposed to work.

I think it's good form.
Thank you!
