Music Player Daemon

Music Player Daemon (MPD) is a server-side software for playing music. It can play various audio files through plugins and libraries, manage playlists, and maintain a music database. It requires a client program for interaction and includes a command-line client, mpc, in its package.

MPD supports multiple audio formats like Ogg Vorbis, FLAC, Opus, WavPack, MP2, MP3, MP4/AAC, MOD, Musepack, and wave files via FFmpeg. It can be remotely controlled over a network, supports both IPv4 and IPv6, and can play FLAC, OggFLAC, MP3, and Ogg Vorbis HTTP streams. It also reads, caches, and searches metadata information.

Additional features include buffer support for playback, gapless playback, crossfading, and seeking support. It allows users to manage playlists in M3U format and has native Zeroconf support, libsamplerate, and native sample rate conversion. It's compatible with various audio systems like ALSA, PulseAudio, PipeWire, OSS, MVP, JACK, Windows, and macOS. MPD can be used as a source for an Icecast stream, features a built-in HTTP streaming server, and can play music files inside .zip archives. It operates independently of a GUI, so music continues to play without a front-end.
