Show 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.

| 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

| Console says "WebRTC: ICE failed, add a TURN server and see

|
| 1. Streamed via Blackhole and music was constantly slowing down

| 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.
