i don't have a lot of experience with node, but i do know the
architecture is event driven. is it even possible to view the current
API from this perspective?

obviously, each note is an event. but for "music" we need to put events
into a certain larger pattern ... this seems like an interesting type of
problem to me, but i may be misunderstanding it completely.

Chinmay that's a great idea! If there are people willing to help, I'm happy
to coordinate the effort.
However, there is in my opinion one biggie that should be addressed before
more functionalities are added. This is the fact that right now audio runs
in the main thread, and I was thinking at possibilities to run it somewhere
else. Unfortunately node doesn't support multi-threading, which leaves us
with multi-processing as only solution. However, the major issue with that
is sharing / transferring of big buffers. There was a discussion going on
in this thread : https://github.com/sebpiq/node-web-audio-api/issues/16

Once we get the architecture right, I think this up-for-grabs is a great

What is "the right way" to redirect a thread from web-audio to

Hey Sebastian,

I think getting the community behind this and maintaining a standards
compliant nodejs version of WebAudio API would be something very useful and
powerful to have in the long run.

I will definitely try to spend some weekends trying work on unimplemented

I was wondering how we could get more people in the WebAudio community to
help out with implementing parts of this. Would breaking down features and
tagging them up something like 'up-for-grabs' (http://up-for-grabs.net/)

Hi Tristan,

I've been working on this, with help from some other people :

There is barely any node : ScriptProcessorNode, GainNode and
BufferSourceNode. Samuel Goldszmidt started adding Oscillators and Delay
nodes here :
https://github.com/sebpiq/node-web-audio-api/tree/Oscillator+DelayNodes but
he said it still needs some work.

So you can use it, but keep in mind that it is really a work in progress!!!
And also, I think the codebase is pretty clean, and documented, so if you
feel like implementing more nodes :D

Is there a JS engine that will let me do this?
