MPD is a headless music server daemon that indexes audio libraries and streams music to local or remote outputs. It functions as a music library manager and network audio streamer, providing a remote audio control protocol that allows external clients to manage playback, playlists, and database queries.
The system acts as a multiroom audio coordinator, synchronizing audio distribution across multiple networked clients and hardware devices. It supports a variety of remote management capabilities, including a dedicated control API and the ability to broadcast audio streams over network protocols.
The server provides a comprehensive suite of audio playback and processing tools, including bit-perfect output, loudness normalization, and track cross-fading. Its content management capabilities cover metadata parsing, music library indexing, and persistent playlist management, while its hardware integration allows for flexible audio device routing and external mixer coordination.
The project is implemented in C++.
