Generally looks fine; r- because of an inconsistency in the publicly visible attributes. Also a couple of minor suggestions.

> WebCore/webaudio/AudioDestinationNode.cpp:50
> +    initialize();
I certainly hope that AudioNode initializes the m_isInitialized flag to false in its constructor. It would be simpler if AudioNode were landed before this class which depends on it.

> WebCore/webaudio/AudioDestinationNode.cpp:71
> +    m_isInitialized = true;
I would suggest just calling AudioNode::initialize() here and making m_isInitialized private in AudioNode (assuming that's where it's declared).

> WebCore/webaudio/AudioDestinationNode.cpp:81
> +    m_isInitialized = false;
Same comment, but about calling AudioNode::uninitialize().

> WebCore/webaudio/AudioDestinationNode.idl:34
> +        readonly attribute short numberOfChannels;
This attribute isn't currently in the Web Audio spec.

Ken, I've created a new patch to address some changes to AudioContext.  I've added the "numberOfChannels" attribute to the web audio specification document.  I spoke with you offline about keeping the initialize/uninitialize part as it is.  But I *did* add addInput() and addOutput() methods to AudioNode.

Looks fine. Tiny formatting issue.

> +    virtual void reset() { m_currentTime = 0.0; };

No semicolons at end of lines.
