A client-server audio player that synchronizes multiple clients for perfectly synced multiroom audio playback.
Snapcast is a synchronous multiroom audio player that turns existing audio players into a synchronized multiroom system. It works by capturing audio from a server and streaming it to multiple clients that are perfectly time-synchronized, solving the problem of audio lag across different rooms. It is not a standalone player but integrates with players like MPD, Mopidy, AirPlay, and Spotify.
DIY audio enthusiasts, home automation integrators, and developers looking to build or extend a whole-home audio system using existing hardware and open-source software.
Developers choose Snapcast for its precise synchronization, flexibility to work with almost any audio source, and ability to self-host a multiroom system without proprietary hardware. It offers an open-source alternative to commercial systems with extensive control APIs and cross-platform support.
