           Summary: "PlaybackTime" parameter is not present in
                    AudioProcessingEvent Interface as per W3C spec
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: Web Audio
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kaustubh.j at samsung.com
                CC: crogers at google.com


As per W3C WebAudio Spec AudioProcessingEvent Interface should have parameters like below:

interface AudioProcessingEvent : Event {

        JavaScriptAudioNode node;
        readonly attribute float playbackTime;
        readonly attribute AudioBuffer inputBuffer;
        readonly attribute AudioBuffer outputBuffer; 

    }

W3C Spec link: http://www.w3.org/TR/2012/WD-webaudio-20120802/

The parameter "playbackTime" is not present in latest WebKit-137862. Also if required, necessary calculations to update the playbackTime parameter need to be implemented in AudioProcessingEvent.

Current Implementation AudioProcessingEvent.idl:
[
    Conditional=WEB_AUDIO,
    JSGenerateToJSObject
] interface AudioProcessingEvent : Event {
    readonly attribute AudioBuffer inputBuffer;
    readonly attribute AudioBuffer outputBuffer; 
};
