Six independent paths reach analysis_cache::seed_from_bytes for the same
track_id during a cache-miss play under LUFS:
- track_download_task legacy stream capture-complete
- ranged_download_task HTTP buffer full
- audio_preload bytes-ready
- psysonic-local file-read complete
- spawn_analysis_seed_from_in_memory_bytes (gapless reuse / preloaded /
stream cache)
- analysis_enqueue_seed_from_url (frontend backfill triggered by
refresh:miss while a playback path is mid-seed)
Whenever a track is streamed for the first time with loudness on, two of
these fire in parallel and Symphonia + EBU R128 decode the same buffer
twice — ~30 s of duplicate CPU per track, plus a redundant SQLite write
of an identical row. Reproduced on multiple cache-miss tracks (KjP… ranged
+ backfill, mPdz… preloaded bytes + backfill).
Coordinate at the funnel:
- New SeedFromBytesOutcome::SkippedConcurrent variant.
- SEEDS_IN_FLIGHT static (Mutex<HashSet<String>>) tracks track_ids whose
analysis is currently running. First caller into seed_from_bytes
wins the slot via HashSet::insert; later callers return SkippedConcurrent
immediately and let the winner publish the analysis:waveform-updated
event.
- SeedInFlightGuard (RAII) releases the slot on every exit path including
panics, so a crashing analysis cannot leak the marker.
- enqueue_analysis_seed in lib.rs distinguishes the SkippedConcurrent log
from the genuine "seed result" log so the frontend backfill case
(when it arrives second) doesn't read like a backfill failure.
Existing call-site match arms in audio.rs already use Ok(_) => {} for
non-Upserted outcomes — no changes needed there. enqueue_analysis_seed in
lib.rs already gates the waveform-updated emit on outcome == Upserted, so
the new variant is silent there too.

Psysonic
The Ultimate Desktop Client for Self-Hosted Music Libraries
Fast. Beautiful. Native. Feature-packed. Built primarily for Navidrome. Also compatible with Gonic, Airsonic, LMS and other Subsonic-compatible servers with partial feature support.
No telemetry • Native performance • Massive feature set • Community driven
Warning
Psysonic is under heavy active development. Bugs and rough edges are to be expected. We reserve the right to change, remove, or rework existing features at any time without prior notice.
Server Compatibility
Psysonic is optimized first and foremost for Navidrome.
Many advanced functions integrate directly with Navidrome APIs for the best possible experience. Other Subsonic-compatible servers generally work well, but some features may be limited depending on server capabilities.
Why Psysonic?
Most Subsonic clients feel like web wrappers.
Psysonic does not.
It is a true desktop experience built with Rust, Tauri v2, and React for users who care about speed, aesthetics, customization, and serious music library management.
If you host your own music, this is what the premium experience should feel like.
