* fix(perf): skip Performance Probe CPU snapshot poll on Windows Windows has no Rust CPU/RSS sampler, but the probe still invoked performance_cpu_snapshot every 2s when the modal or overlay pins were active. Skip the IPC on unsupported platforms and only poll JS-side metrics; do not start overlay polling for CPU/memory pins alone. * fix(analysis): park backfill coordinator until Advanced is configured #881 started run_coordinator_forever at app init with a 2s sleep even when disabled, waking tokio on every platform for no work. Park on Notify instead; wake on configure (enable/disable) and library sync-idle. Long sleeps use select with wake so sync-idle can interrupt COMPLETED_RECHECK waits. Investigation branch — not for merge until periodic CPU root cause is confirmed. * fix(perf): stop probe overlay flicker on live poll updates Publish CPU samples only after a valid jiffies baseline, skip no-op snapshot emits, and sync sparkline history atomically in the store. Overlay uses wall-clock sparkline time and auto-scales low CPU values. * fix(perf): cut idle Rust CPU from probe scan, cover prefetch, and storage poll Move performance_cpu_snapshot /proc work to spawn_blocking so tokio workers are not charged with probe sampling. Stop lazy cover strategy from running route prefetch disk stats every 1.5s, and slow hot-cache size refresh on Settings → Storage to 15s. * fix(perf): stabilize probe sparkline clock between live poll ticks Track sampleAt separately from updatedAt so CPU rate history and overlay sparklines only advance on real % changes, not FPS re-renders or RSS-only poll ticks. Hold CPU sparkline Y scale with a peak ref to avoid scale jumps. * fix(cover): restore lazy route prefetch without idle disk stats poll Re-enable lazy cover registry warm-up so cached WebP paths reach diskSrcCache before cells mount. Skip cover_cache_stats on every 1.5s tick — drain batches via ensure only, poll full disk usage every 30s when the registry is idle. * docs: CHANGELOG and credits for PR #939 idle CPU perf fix * fix(cover): peek before route prefetch ensure to match main responsiveness Route prefetch moved batch drain ahead of cover_cache_stats for idle CPU, which removed the accidental throttle and flooded ensure invoke slots. Use warmCoverDiskSrcBatch first (cached hits skip ensure), ensure misses only, and yield while high-priority viewport work is queued.
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.
