Lyrion Music Server

Free your music.

What is Lyrion?

Lyrion Music Server, formerly known as Logitech Media Server (LMS) or SlimServer, is a mature, community-driven, open-source audio streaming platform. It acts as a central hub for your music, allowing you to stream your personal local music collection (MP3, FLAC, ALAC, DSD, etc.) alongside major internet streaming services to any room in your house.

Unlike many modern alternatives, Lyrion is completely independent of any single hardware brand or cloud service. It is designed to be lightweight enough to run on a low-power Raspberry Pi, yet powerful enough to manage libraries containing hundreds of thousands of tracks on high-end servers or NAS devices.

Why Choose Lyrion?

Lyrion is the premier choice for music enthusiasts who value control and longevity. While commercial systems often lock you into specific hardware or monthly fees, Lyrion offers:

Lyrion runs everywhere

It runs on almost anything, from a vintage laptop to a high-end NAS, Raspberry Pi, or Docker container.

Lyrion philosophy

Based on the Lyrion philosophy, the system is built on these four pillars:

Free Software: Completely open-source and free to use forever.
Hardware Agnostic: Use your existing audio gear, AirPlay receivers, Chromecasts, or DIY players (like Squeezelite).
Massive Scalability: Effortlessly handles libraries with 100,000+ tracks with lightning-fast indexing and search.
Perfect Multi-room: Achieve sample-accurate synchronization across your entire home, regardless of the different hardware brands you use.

Detailed Feature Analysis

1. The Power of Plugins

Lyrion’s greatest asset is its community repository. Lyrion allows you to "bolt on" features to suit your specific needs:

Material Skin: A modern, responsive web interface that transforms the look into a sleek, contemporary app experience.
Spotty: Arguably the most robust Spotify integration for any music server, allowing full library integration.
Music and Artist Information: Automatically pulls biographies, lyrics, and high-quality artwork from multiple web sources.
Bridge Plugins: Use the UPnP/DLNA, Chromecast, and AirPlay bridges to turn almost any smart speaker into a Lyrion player.
DSD support: Supports DSD64, DSD128, and DSD256. Through the DSDPlayer plugin, it handles .dsf and .dff files. It offers "Native DSD" for supported DACs on Linux/Windows and "DoP" (DSD over PCM) for macOS and hardware-limited bridges. Also, it can transcode DSD streams to players that don't natively support them.

2. Interfaces and Customization

Lyrion isn't locked into a single "look." Users can choose their experience:

Classic Web UI: Lightweight and functional for older hardware.
Material Skin: The gold standard for modern browsers and mobile devices.
JiveLite: A specialized interface for local displays, perfect for Raspberry Pi touchscreens.

3. Metadata and Library Management

Lyrion is famous for its ability to handle complex libraries where others fail.

Classical Music Support: Proper handling of "Works," "Conductors," and "Composers."
Box Set Management: Intelligent grouping of multi-disc sets.
On-the-fly Transcoding: The server can downsample hi-res files in real-time for older devices while maintaining the original quality for your main Hi-Fi system.
