THE CORE
One authority for the whole library.
Core separates what the music is from where a copy happens to live. That gives you one catalogue, proper editions, persistent artwork and one playback state across every Control client.
LIBRARY
Albums, editions and copies
Multiple copies do not become duplicate albums. Remasters, alternate mixes and real editions stay distinct.
INGEST
Bring the collection in
Local and network files, optical media, Bandcamp, audiobooks and supported legacy sources all feed the same catalogue.
PLAYBACK
Tell the truth about the path
Core tracks source, conversion, transport, endpoint and physical output instead of claiming bit-perfect playback when the route cannot deliver it.
BUILT FOR REAL COLLECTIONS
The library is more important than the folder tree.
Core keeps the user's decisions authoritative. Metadata services can help identify releases and artwork, but rescans should not undo a manual correction or turn a second storage copy into a fake second album.
Preserve the master
Original media stays original. Compatibility conversions are playback decisions, not destructive changes to the library master.
Persistent artwork
Chosen artwork belongs to the logical release identity and survives restarts, rescans and metadata edits.
PostgreSQL authority
Core owns the canonical catalogue and revision state; clients consume it rather than independently inventing their own library truth.
Headless by design
Debian 13 runs the appliance. Core Web and Control provide the UI; a customer should not need to live in a Linux shell.
SOURCES & OUTPUTS
Keep old hardware useful. Add new routes around it.
Meridian / Sooloos
Existing libraries and zones can participate alongside Core storage rather than being thrown away.
Sonos & Cast
Core Cast handles supported network renderers including Sonos, AirPlay and Chromecast capability paths.
Core & End
Native endpoints can expose the actual audio capabilities of attached hardware so Core can choose a truthful playback route.
CORE ON YOUR PLATFORM
Debian, Windows or Mac.
Choose the Core server installer for your operating system. Debian 13 has a 1.0.3 QA8 package and QA11 installation ISO. macOS now has a Developer ID-signed universal QA build (not notarised). Windows Core remains an unsigned Alpha.
