* feat(playback): stream buffering UI, ranged M4A tail prefetch, demuxer fix Defer seekbar/progress until HTTP stream is armed for both legacy and RangedHttpSource; show buffering overlay on cover art. Add MP4 tail prefetch and Symphonia isomp4 bounded-mdat/moov-at-EOF probing so moov-at-end M4A can start without reading the full mdat. * feat(hot-cache): spill large ranged streams to disk for promote When a ranged HTTP download completes above the 64 MiB RAM promote cap, write the existing buffer once to app-data stream-spill/ and register it for hot-cache promote (rename) and replay via fetch_data. Analysis seeds from the spill file up to the local-file cap (512 MiB). * fix(ui): stream buffering — grayscale cover and static clock icon Desaturate player and queue cover art while isPlaybackBuffering; keep a non-animated clock overlay for visibility without the spinning animation. * fix(playback): review follow-up — tests, i18n, spill cleanup, changelog Clippy and test layout fixes; stream spill orphan cleanup on startup; buffering flag guard in progress handler; bufferingStream in all player locales; CHANGELOG and contributor credits for stream/M4A work. * docs: attribute stream buffering and M4A streaming to PR #737 * test(audio): avoid create_engine in stream spill unit test CI runners have no audio output device; test spill take/consume via the Mutex slot only, matching install_stream_completed_spill tests.
A modern desktop client for self-hosted music libraries
Fast. Native. Beautiful. Built for people who actually care about their music collection.
Psysonic is built primarily for Navidrome and also works with Gonic, Airsonic, LMS and other Subsonic-compatible servers, depending on the features supported by your server.
Available languages: English, German, Spanish, French, Norwegian Bokmål, Dutch, Romanian, Russian and Chinese.
More translations are added over time.
No telemetry • Native performance • Navidrome-first • Community driven
Warning
Psysonic is under active development. Bugs and rough edges can happen, and features may change as the project evolves.
What is Psysonic?
Psysonic is a desktop music client for self-hosted music libraries. It is designed for people who want the freedom of their own server without giving up the comfort, polish and speed of a modern music app.
It is built with Rust, Tauri v2 and React, with a strong focus on responsiveness, customization, practical music-library workflows and a user interface that does not require a manual before you can press play.
Psysonic is optimized first and foremost for Navidrome. Other Subsonic-compatible servers can work well too, but advanced features may depend on server-side support.
