Decibel Audio Player is a GTK+ open-source (GPL) audio player for GNU/Linux. It is very straightforward to use thanks to a clean and user-friendly interface. It is especially targeted at Gnome and follows the Gnome HIG.
Decibel Audio Player is built around a highly modular structure that lets the user disable completely the features he does not need. A disabled feature uses absolutely no memory and no processor time.
Decibel Audio Player is a real audio player and does not include features that are not meant to be part of an audio player. These features, such as tagging files or burning CDs, generally have a better support in dedicated software. If you are looking for an audio player that can make coffee, then you should stay away from Decibel and give a try to other players (e.g., Amarok, Exaile).

Snapcast is a multi-room client-server audio player, where all clients are time synchronized with the server to play perfectly synced audio. It’s not a standalone player, but an extension that turns your existing audio player into a Sonos-like multi-room solution. The server’s audio input is a named pipe /tmp/snapfifo. All data that is fed into this file will be send to the connected clients. One of the most generic ways to use Snapcast is in conjunction with the music player daemon (MPD) or Mopidy, which can be configured to use a named pipe as audio output.
