            Bug ID: 143332
           Summary: Web Audio API filter not working in Safari
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Macintosh Intel
                OS: Mac OS X 10.10
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Audio
          Assignee: webkit-unassigned at lists.webkit.org

I am in the process of developing an HTML5 canvas interactive piece that uses Createjs and the Web Audio API. I've managed to get audio working in Chrome/Firefox/Safari despite the deprecation of webkitAudioContext by Chrome and FF but not Safari. However, filters for some reason are not working in Safari, but sound still plays. Filters DO work in Chrome/FF.

I have my filters set up like this:

    var sound = new Audio();
    sound.src = './sounds/sound.mp3';
    sound.autoplay = false;
    sound.loop = true;
    soundSource = context.createMediaElementSource(sound); 
    var soundFilter = context.createBiquadFilter();
    soundFilter.type = "lowpass";
    soundFilter.frequency.value = 500;
    soundSource.connect(soundFilter);
    soundFilter.connect(context.destination);

I found [this](http://webaudioapi.com/samples/filter/) example of a lowpass which works in Safari, but I've no idea. I have a hunch this has to do with "createMediaElementSource". Any help would be appreciated!
