Unfortunately my development on WebPd is divided between my clients (day job) and other spare time projects so it doesn't always get the love it needs. So far it has kept plodding along due to some really awesome and huge patches from Brandon and Spencer with an occasionally architecture tweak from me. would it make sense for you to open up a pd-ext.js file, where non-vanilla objects are coded? Yes, perfect sense. Or someone could make their own pd-ext.js or pd-zexy.js or pd-gridflow.js and self-publish them. There are already some non-vanilla objects in pd.js though which I should move into pd-ext.js and that is a good idea, thanks.

[PD] Pd - DSP in a web app
Hi all, I've been toying with some new HTML tags (canvas and audio), in a an attempt to build a web app that would work as a simple sequencer. Although canvas is great, i'm not fully satisfied with the audio tag. I was wondering, is there a way i could use Pd as a sound engine in a web application? Can it run on a server? Sorry if this is a silly question... There was a discussion a few months back about a project calld WebPd. Anybody knows if it's been developped any further? Cheers!

Re: [PD] Pd - DSP in a web app
A few people (myself included) have built web UIs that control PD patches that run on a server. The technique I've used involves an http server that acts as a gateway, transforming http requests into OSC messages which are then sent to PD patches. My blog has some info about some of my experiments: http://www.pillowsopher.com/blog/ I've also been looking at wrapping libpd (http://gitorious.org/pdlib/pages/Libpd) in a web server (maybe writing a node.js binding?) and using that to generate audio based on data from a web browser. andy On Tue, Mar 29, 2011 at 8:07 AM, Pierre Massat pimas...@gmail.com wrote: Hi all, I've been toying with some new HTML tags (canvas and audio), in a an attempt to build a web app that would work as a simple sequencer.

Re: [PD] Pd - DSP in a web app
Those are both good reads. The Web Audio! All Aboard article is pretty inspiring. As for running Pd on a server, if the user's don't need to share data (for example, if you are streaming the results of their patches back to them) you could run one instance of Pd per user. That way one user couldn't kill audio for everyone. In most of the work I've done the web UI interacts with Pd patches, but it doesn't actually send patches, so to the extent that I trust my own patching ability, I can feel fairly certain that my instance of Pd won't crash. I guess I assumed that with the sequencer that's the type of thing you would be doing. andy On Tue, Mar 29, 2011 at 11:00 AM, Pierre Massat pimas...@gmail.com wrote: I think you should all read this: https://wiki.mozilla.org/Audio_Data_API and this: http://weblog.bocoup.com/web-audio-all-aboard I believe it only works in Firefox 4 at the moment.

Which means that if any patch crashes Pd there'll be no sounds anymore? Well, the question is how the audio is getting to the user. As you said, WebPd requires FF4's audio API. If you want the actual Pd running on a server then you need a way of hearing the output. In my own pd-on-the-web project, PuréeData, I'll be using an mp3 or ogg stream.
