ah, nice. very clever! would love to check that out!
I may be making a bit of headway in looking at rtmp and hls streaming media
servers like mist server and the rtmp module for nginx webserver. it
accepts a raw connection to its input ports.
my question now becomes, which of the signal capable network objects can
work without an associated in~ object? i have been toying with netsend~,
udpsend~ mp3streamout~ streamout~ and mp3cast~, which works with the
icecast server, but the others return errors so far. i have the greatest
confidence in getting the netsend~ to eventually work, but does anyone have
any experience with the others in regards to sending their outputs to
non-pd or max based inputs like network ports set up to recieve other data?

Hello list,
I have trouble with automatically choosing audio devices because the
list of available device is not the same each time I launch pd.
I am on ubuntu 12.04 / pd 0.44.3. I want to use portaudio with the
"pulse" device because I'm running another software in parallel, that
can only use pulse for playing sound.
When I launch pd, the list of available device for portaudio is not the
same each time... that makes difficult to choose pulse automatically.
Is there anything I can do to be sure of choosing the good device?
Here is an output of 3 different launchs:

Thanks in advance for your help.

was this using wifi? how were you able to implement it? was it a server
type system or a broadcast system? might need to bike alternators as well
to power this joint, lol.

yes please! that sounds perfect. i mainly need to know to bit that serves
up the audio at low latencies. ive got the icecast server stuff working
wirelessly to multiple devices but the latency is killing me (10-5 sec).
would it be possible to use your server directly to the browser?
currently, i simply need a low latency stereo audio instance to come on
when they log into my network. that is it (for now) i have alot of other
things i want to build around it, but i really need to know
1. what format does pd need to output to useful to...
2. a way to serve said audio out from my wireless router
3. instant sound output as soon as they login.
so far, i have investigated web audio api and just started digging into the
idea of feeding the audio feed as a data dump so i can at least see that it
is transmitting anything-garbage-to the browser, then i can figure out how
to deal with it after that is sorted. i am playing with netsend~ right now
with mixed results (server connection issues). any insight is much
appreciated.

"Onyx, is that an idea? Most cell phones do have an FM receiver. They only
work with wired headset connected, functioning as antenna. As wired
headsets can be cheap, just offer them for sale during the event. The good
thing with FM is, it has zero latency. I got a LinexFM transmitter from
here:"
not for this project. I want to explore this new "everyone has a wifi
capable cellphone" space for a while, without plugins or apps. I have
gathered quite a bit of data to that effect in the last day or so. there
are audio api's for the various browsers that do the same thing is slightly
different ways. i want to trick the server into accepting the output from
a network object out of pd, but i am also open to finding a low latency
server like the one from kaazing. still studying though.

Dear List,
Flux is a digital sound sculpture for Android devices. It is our latest
artifact built with libPD. You can grab & tweak the patch, download the app
from here >> http://www.binaura.net/stc/wrx/flux/
It would not be possible to build the synthesis engine without the Pd
community, special respect to the RJDJ team for their high level (brilliant
Vanilla-based) objects... thanks
..and share the source
Yours,
Binaura

Hi list,
Sei and I have launched Pure Data Portal Website for Japanese users in February (http://puredatajapan.info)
and we are very happy to announce that we will hold a launch event of our portal website in May.
The entire event will be webcasted using Ustream; We have selected a venue specialized for it!
The event features not only presentations and lectures but also many demos and live-performances by Japanese Pd users.
For example, a user employs Pd for controlling LED-corsage, and another presenter utilizes Pd for getting data from his own touch-interfaces.
We are pretty sure that the show will be inspiring even if you do not understand Japanese ; )
Website: http://tokyomax.jp/pd/
The URL of the webcast: http://2-5-d.jp
Date and Time: May 29. 2013 18:30 - 23:00 JST
The number of Pd users in Japan is gradually increasing.
I hope Pd will soon become one of the most popular creative tools among the citizens of presumably the most geekiest country on the earth !
best regards,
Chikashi Miyama (Pure Data Japan)
Greetings! I hope all is well with you. I wanted to ask if i might gain
some of your insight on a project i am undertaking.
I am currently attempting to stream my audio into html5 capable web
browsers of smartphones. i have created a local network and installed
nginx as my webserver. i and a friend got everything working with the
oggcast~ and mp3cast~ objects and the icecast 2 server, but the latency was
horrific-5-15seconds. I would like to investigate the idea of taking
advantage of the plugin-less nature of these modern fast browsers and pipe
the audio directly into it as directly as possible the same way voip works
but lower bandwidth and only one way.
I see that udpsend~ can do alot of what i think i want, but i am confused
as to how i might connect it with the audio socket in the client browser
(if socket is even the right term).
Any insight would be greatly appreciated. and if i get it working, as
before, i will document the findings in a step by step once it works.
thank you.
cheers!
