Hi HN,

OP here. If you wanna know more about the code involved in this project, I'm happy to answer your questions!

WASM-STREAM is really just a quick hack for rc3, the remote chaos communication congress happening right now.

But so far, I found it quite entertaining to listen to the audio stream.

Edit: Provisioned an ogg-vorbis stream now too. So now the blog should play the stream in Chrome-based browsers too.

Hi! I like what you're doing here. I'm the author of a tool that utilises an opus encoder and decoder in the browser to emulate something like modern live streaming. I followed similar ideas to yours but ultimately found that the icecast route was a little bit limited. If you're interested, the code is here: https://github.com/gaxge and is in the process of being refactored/ updated. You can play around with the original prototype here: https://low.show/noisecrypt/app. I use the streaming tools mainly for doing stuff with jamming in combination with randomness but they can be repurposed for normal linear real-time streaming.

I'm also based in Germany, and you're welcome to reach out if you want to talk about this kind of stuff further.

Oh cool! I'll definitely take a look. Thanks!

Damn it, now you guys are all on my website and the ogg-vorbis encoding (a requirement for the stream working in Chrome) crashed and I'm not at home!

Edit: I finally got home and restarted the ogg stream. Will have to find a solution for it to remain up...

Nice! Are all user inputs mixed into the same stream?

timdaub5• 6 years ago

Yes they are. Technically though it's not mixed. All arriving audio data is dumped into a single buffer. Mixing would now be a great way to get rid of the stream's choppyness.

now that so many users are playing simultaneously, I'm a bit annoyed that some leave the website open and stream silence.

Wondering how I could get a user a fair slot to perform now...

Anyways, the stream has become a great source of entropy now :D

streamer452• 6 years ago

Oh I see. Server side mixing would probably be a good option to help it scale better. Cool stuff anyway :)

So, is this like a giant party line?
