Stack: LiveKit (WebRTC), Next.js, Node.js, Neon Postgres, AudD for music recognition.
What's new in 2.0:
Stream from browser tab or system audio (BlackHole/VB-Cable)
Music recognition with automatic deduplication and "winner selection"
24/7 demo rooms (NTS Radio, SomaFM, and yes... Money For Nothing on loop)
See Lobby rooms from inside a room
Push-to-talk overlay for hosts
Automatically add emotes dropping 7tv.app link in the emoji popup in the chat
Happy to answer any questions! PS. Audio can be shared only by desktop at the moment. Not mobile

So sick. We've been using this at work (we're a small team - 6 people) and it's just so much fun. Great work! Thank you so much!

My project https://hangout.fm/ does this based on turntable.fm and its legal and licensed and pays artists

People running a Sandstorm server might be interested in an app in the same vein called Groove Basin. But it's a single shared stream, and you upload tracks to a library and play queue (rather than streaming from one person's own computer).

Heh, anyone remember MixApp (2008ish?) (streaming your own mp3s to chatrooms, this decade you could probably rebuild it on top of tailscale, it was more shaped like that than modern streaming...)

This is cool! Just hosted a stream but there were a few bugs/issues.
1. Streamed via Blackhole and music was constantly slowing down for me, not sure if listeners had similar experience. 2. Couldn't unmute my mic so you could hear me breathing in the bg at times. 3. If I refreshed the page I couldn't go back to hosting my room. How can I do this? 4. If I blocked my mic all music stopped and re-adding it wouldn't go back to streaming.

I see the marquee with "host a room" and arrows pointing up.
But I don't see a button or anything to actually host a room.
I can only join rooms.
Using Android Chrome.

1. I created a room but after refreshing lost it and then couldn't rejoin or recreate the room
2. Setup is a bit of a painful (had to install software and then still couldn't get audio to work from Rekordbox) so if that could be simplified it would be cool
3. I like the chat, makes me feel like I missed out on the IRC era

Not able to join any room on Chrome and Windows
Also seems to require a password to host a room (can't just leave it open?)

How do you create your own room? How do you connect system audio to a browser?

I clicked everything on the page but couldn't figure out how to join a room. Clicking a room card no worky. I can however view song history

In the late 2000s I hosted an Icecast server for our IRC channel and we had regular "radio" shows presented by channel members. It was great fun. Sometimes people who were in close proximity in real life would turn up as "guests" on other people's shows. We did a thing where people in the channel could pick songs for the show etc.
I know, I know, it's classic to look back wistfully, but I really feel like something was lost in the past 15 years or so. We just cobbled together this stuff from simple components and had fun. I didn't require a PhD to get your head around it, I feel like people were more clever because you kinda needed to be. Nowadays if something isn't part of the shiny web app you're just shit out of luck. Back then we'd just do another hack and it was all good.
