Yes! It uses sink.js! But sink.js uses WebAudio API when it can. The synthesis is made in JavaScript, not in Audio API (yet!). However, I have big plans of refactoring the whole stuff to be all Web Audio API! I started `pd-fileutils` as part of this refactor : I want to separate components to make maintenance easier.

But the Web Audio API version is coming, probably in 3-4 months. If somebody wanna help, they are welcome :) it's quite a lot of work for me alone.

All mentioned in roadmap are implemented (at least partly), except [adc~]. You can check out implemented objects here : http://funktion.fm/webpd/demos/simple-gui/simple-gui.html

Hi Jamie,

The audio is not streamed to the browser! WebPd is an implementation of Pure Data in JavaScript, so the browser itself produces the sound (link here : https://github.com/sebpiq/WebPd) . Since a couple of years, thanks to a new standard called Web Audio API, it is pretty easy to achieve in Firefox, Chrome and Safari. The performance is actually surprisingly good!!!

The graph editor project is called "dataflow" and is made by Forrest Oliphant, link here : https://github.com/meemoo/dataflow
It is all JavaScript as well.

Wow! That's impressive, when I saw this thread I was just expecting a patcher, but you've actually got audio streaming back to the browser. How are you achieving that?

Do you have a link to that project?

best,
