Hi Hans,

That is correct, you need a special build of Firefox to use it now.

Those Firefox-audio patches are getting put in for review for the main
Firefox build tonight, so I think that probably quite soon they will see
the light of day in that browser. Once that happens, WebPd will work by
default in vanilla builds of Firefox, and I guess most Firefox users
download upgrades as soon as they come in[1]. One in three people use
Firefox globally[2], which means this kind of change carries some clout
(The percentage of users in Europe is even higher).

In addition, a w3 working group called AudioXG has been formed which
includes some of the larger companies (I think it is Mozilla, Google, HP,
Yahoo, but not 100% sure about that). I reckon the odds are high that
WebKit (e.g. Safari, Chrome) will follow quickly behind with an
implementation like Mozilla's. [What a pity that WebKit, a fork of the GPL
KHTML, isn't controlled by hackers any more since Apple forked it. I am
really interested to see how Apple will cripple their WebKit implementation
since this technology is so disruptive to part of their core business of
selling music. I doubt very much that the browser on their hand held
devices, for example, will be allowed access to audio. We'll see.]

Also, somebody was working on a small Flash program to allow this stuff to
work in non-audio-enabled browsers[3]. Even if that particular project
doesn't continue, I think it's likely that something to bridge the gap for
IE users will be created.

Basically, Javascript read/writeable audio buffers are coming to a browser
near you very soon. I think it's really cool that some Pd patches will be
working in the browser already when that happens. I've been spending a few
hours of my spare time per day at the moment working on this, and you can
see my progress in the tests which pass here:
<http://mccormick.cx/dev/webpd/tests.html>. Recently I have been getting
messages and triggers, and [line~] working.

Patches welcome. :)

Cheers,

Chris.
