Actually, I've wanted to do this for some time, but there are a few  
limitations of the JS node that makes it impossible to re-implement  
most nodes with it (at least in a way that makes them operate  
identically). Apart from Bug 17388, we also have:

https://www.w3.org/Bugs/Public/show_bug.cgi?id=17533
https://www.w3.org/Bugs/Public/show_bug.cgi?id=17534

(and possibly some other things that I've forgot about)

In any event, in order to put the DSP API to test, I'm currently doing  
a Web Audio API-kindof-subset-reimplementation in JavaScript (does not  
require Web Audio API - more of a shim). Not quite there yet, but  
making progress. Will let you know how it turns out (if/when I have  
the time to complete it).

Regards,

   Marcus
