Cordata

Cordata is a control point and discovery layer for a local hi-fi library. It drives HQPlayer or a UPnP/OpenHome renderer on your network and turns your own collection into something you actually explore — not just a file list.

Requires a renderer on your network: HQPlayer (Embedded or Desktop with Network Control), or any UPnP/OpenHome renderer — a network streamer, a NAS running MinimServer/Asset, etc. Cordata is the remote and the brain; it doesn't replace your server. If you don't run one of these, this isn't the app for you (yet).

Rediscover your own library
• Home that fills in as you listen — recently played, most played, forgotten favorites, rediscover, by decade
• Radio: build an endless station from any track, artist, or album — it starts instantly and never repeats an artist back-to-back
• Surprise Me — one tap to reshuffle and rediscover a large collection
• Smart Mixes themed by mood, energy, and era

See the truth about every file (with the optional, free companion sidecar)
• Roon-style waveform seekbar
• Dynamic Range, BPM, and musical key for the playing track
• A provenance verdict that flags upsampled "hi-res" — plus per-track spectrograms
• Synced lyrics and high-resolution embedded artwork

A listening history that's yours
• A real dashboard: heat map, top artists/albums/tracks, sound-quality breakdown, streaks, trends
• Time Machine — what you played on this day in years past
• Export your history, sync to ListenBrainz, import from Last.fm — your taste graph stays portable

Rich context, on device
• Apple Music editorial notes, artist bios, similar artists, and the playlists that feature them (a permission — no Apple Music subscription required)
• Apple Intelligence album insights

Ratings, play counts, and all your metadata sync privately across your devices via iCloud.

Optional companion: a free, open-source sidecar you run alongside your library unlocks the file-analysis features above. Cordata works without it — the companion just elevates it.
