Onyx,
Interesting idea.
What kind of threshold are you looking for regarding latency? I assume this would be for a local network, right?
If I were you, I would first try to fine-tune your current setup by getting all latency variables as low as possible (icecast, pd+oggcast~, and the html audio player).
ICECAST: There should be config settings for it where you can manage the buffering/latency. Usually buffering/latency is good for streaming media since you never know what will happen on the network.
oggcast~ : I'm guessing it is as low as it can go right now, but there may be an internal buffer that you can adjust/downsize.
HTML audio player: Most importantly, in the HTML, you should check to make sure that the audio is not buffering. My guess is that this is where you are experiencing the largest latency. Since HTML5 is a moving target, I'm not sure how you would currently do that. May not even be possible. https://developer.mozilla.org/en-US/docs/HTML/Element/audio
...
Then, if the above didn't work, you might try to hook up the output of a TCP netsend to a websocket and then translate the audio data chunks into JS Audio. UDP won't work on websockets AFAIK.

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 y> cheers!
