Shairport Sync is an AirPlay audio player - it plays audio streamed from Apple devices and AirPlay sources such as ForkedDaapd (but apparently not rtunes). Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible for players that support it.
