alt Hacker NewsShow HN: Pulse 2.0 – Live co-listening rooms where anyone can be a DJ
I wanted to listen to music with friends who live far away. Not "watch a YouTube video together" - actually share what I'm hearing in real-time, like we're in the same room.
Pulse is what came out of that. Anyone can host a live audio stream from their browser tab or system audio. Listeners join, music recognition identifies tracks automatically, and there's chat with 7TV emotes. No account required - you get an anonymous code and you're in.
We're running demo rooms that stream NTS Radio and SomaFM 24/7 (indie project, not affiliated - we backlink to the original stations). There's also a "Money For Nothing 24/7" room if you want to loop that Dire Straits instrumental forever.
Think of it as co-listening infrastructure. Bedroom DJs, listening parties, or just sharing your current vibe.

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...)
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
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
neat!
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.
