Hi Stéphane, this is interesting stuff!  WebKit is pretty hackable, and
there are definitely pretty targeted places in the Web Audio implementation
there to create a specialized AudioNode, etc.  I can help you offline to
give you some general ideas for how to do it.  In the early days, the Web
Audio API implementation itself was much more experimental and something I
effectively "hacked" into WebKit.  I worked on a local branch on my machine
for awhile, and then a special audio branch in WebKit before the work was
polished enough to be at the stage where the code could land in the main
WebKit branch.
