Resonance Music rebuilds an earlier Qt Widgets player as a cross-platform Flutter application for local music, licensed previews and downloads, on-device behavior history, and explainable recommendations.
The project spans desktop and mobile layouts, local and online sources, persistent playback state, preview and download licenses, and cold-start recommendations.
A traditional single-window player does not adapt well across platforms. Opaque cloud profiles undermine privacy, while media sources require clear boundaries between preview, cache, and permanent download.
Ports isolate playback, media sources, persistence, and recommendation logic for testability.
Pages, navigation, themes, and player controls.
Coordinates search, playback, favorites, and recommendations.
Tags, events, preference vectors, and ranking.
Local files, public search, and licensed media adapters.
Favorites, history, cache, and preferences.
One UI layer covers four platforms while preserving platform-specific file, storage, and playback capabilities.
Metadata search is separated from actual playback through licensed providers.
Personalization starts only after enough useful signals have accumulated.
Older behavior decays over a 45-day half-life, with freshness, repetition, and artist-diversity adjustments.
