case study
justecho.me
Real-time synchronized music playback across devices — Spotify, Apple Music, and NFC pairing.
overview
Echo synchronizes music playback across multiple devices in the same room — aiming for roughly ±50ms sync accuracy — with an NFC-tag pairing flow and a grouped-listening-session concept called a 'Chamber.'
what was built
A small Socket.io-based backend coordinating playback timing across connected clients, supporting both Spotify Connect and Apple MusicKit JS as playback sources.
outcome
Working proof of concept; still early rather than a finished product.
