Re: Questioning the current direction of the Web Audio API

@Olivier : if this is the crux of the matter, what is the idea behind the
existence of AudioNodes?

@Hongchan : I really didn't mean to criticize your work. In fact, this was
not clear in the original post, but when I referred to "few good libraries
out there", I was referring to waax as well ... which I have used, and
which I got inspiration from to do the current round of WebPd refactoring.
So all apologies if you misunderstood me.
On the other hand, you cannot say that looping over a buffer of white noise
to generate white noise is not an ugly hack ... and though you probably do
your best to implement as many nodes as possible by composing the existing
AudioNodes, you will never ever get even close to a library like
SuperCollider in terms of amount and quality of UGens available.
