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

Hello,

The versions of Chrome that I am using are:

Version 30.0.1599.66 for MAC (works perfectly)
Version 29.0.1547.59 1547059 on Android 4.1.2 (lt26w, works but with
glitches)
Version 30.0.1599.16 on iOS 6.1.3, iPod Touch 5th (doesn't play any sound,
I guess the onaudioprocess is not being triggered)

Regards!
