Why is there a difference between the JS and V8 bindings in whether these values are null-checked at run time? Please make the two bindings work identically. If this isn't supposed to happen then make it an ASSERT.

I've added error checking in the JS custom binding as well.

The V8 bindings are throwing a ReferenceError, so to be consistent you should do the same here and below.

> WebCore/bindings/js/JSAudioContextCustom.cpp:42
> +    Document* document = static_cast<Document*>(jsConstructor->scriptExecutionContext());

From looking at some of the other custom bindings, you need to check ScriptExecutionContext::isDocument() before casting to Document* to be safe. Since you're already doing the other checking you might as well do this too.
