Re: ScriptProcessorNode/JavaScriptNode iOS vs Android vs MAC OS ( Safari - Chrome)

Kaustubh,

I am attaching you my code. As I told you before it's working on:
Chrome
Version 30.0.1599.66 for MAC
Version 29.0.1547.59 1547059 on Android 4.1.2
Safari
Version 6.0.5 for MAC

Not working on (I can't hear anything, I guess the onaudioprocess isn't
called):

Chrome
Mobile iOS 30.0.1.1599 iPad 4 / iPod Touch 5th     (iOS 6.1.2 - iOS 7)
Safari
Mobile Safari 7.0
Mobile Safari 6.0

I will raise the bug to bugzila in a moment!

Thank you!

PS: The glichtes on Android were because the buffer size were too small...
It's ok on Android now! :)
