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.

Could you build this?
Partial A basic prototype using WebRTC or off-the-shelf streaming is vibe-codeable, but low-latency, synchronized real-time system audio broadcasting to multiple listeners requires specialized media server infrastructure.
What it would actually take: The architecture requires an SFU (Selective Forwarding Unit) media server cluster (e.g., LiveKit, Janus, or Mediasoup) connected to WebRTC browser capture APIs (getDisplayMedia) and a low-latency audio transcoding pipeline. The hard part is clock synchronization across geographically distributed listeners to avoid audio drift/echo while keeping latency below 200ms at scale. It requires WebRTC systems engineering and real-time audio networking expertise.
