* fix(loudness): target sync, -14 pre-analysis ref, queue UI, and reseed
- Front: coalesce loudness refresh by target LUFS; replay-gain IPC dedupe keys
include norm target and effective pre-attenuation so TGT changes apply.
- Rust: placeholder gain before integrated LUFS uses pivot at -14 LUFS; UI gain
from effective trim; reseed loudness after delete when waveform cache would skip.
- Pre-analysis: store attenuation relative to -14 LUFS; engine and UI use an
offset for other targets; migrate legacy absolute values on rehydrate.
- Queue/Settings: Loudness/TGT labels vs value buttons; styles; i18n for help.
* fix(i18n): simplify loudness pre-analysis helper copy
Remove reference-target wording from loudness pre-analysis helper text and keep
only the effective adjustment shown for the current LUFS target in all locales.
Persist waveform v4 as paired curves per bin (peak and mean absolute value),
invalidate cache rows with insufficient data shape, and render the seekbar as
0.7 * mean + 0.3 * peak for a denser, more stable contour.
Thanks to @peri4ko for proposing this waveform improvement.
Serialize heavy PCM seeding through a dedicated queue with optional priority
for the current track. Emit waveform-updated once per completed seed, fix
Lucky Mix waveform refresh tokens, redact Subsonic URLs in logs, and align
hot-cache prefetch with the queued path.
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.

- Emit streaming partial loudness only when the loudness normalization engine is active
- Seed waveform/loudness from in-memory full buffers (preloaded, stream cache, gapless reuse) so offline hot cache does not rely on HTTP backfill
- Add explicit ranged/local/preload logs before full-file Symphonia + EBU analysis
- Coalesce concurrent waveform DB reads and skip duplicate audio_set_normalization within 450ms (e.g. StrictMode double init)
Resolve integrated loudness from SQLite only at decode bind; keep pre-trim
until a row exists, then allow provisional gain from live updates. Pass
DB-stable hints from the web app into play and gapless preload.
Default pre-measurement attenuation -4.5 dB with an icon reset in Settings;
drop redundant normalization copy and shorten pre-trim descriptions.
analysis_cache seed_from_bytes returns an outcome and skips redundant
waveform work on cache hits; wire callers and related frontend/backend glue.
Improve seekbar fallback behavior by using consistent bar-based rendering and smoother transitions to analyzed waveform data. Reduce hot-path analysis overhead during ranged streaming and add controls to clear cached waveform entries.
- Add Tauri command to delete loudness_cache rows for a track and helpers in AnalysisCache.
- Queue tech strip: click dB to reseed loudness; LUFS target picker via body portal; metric styling aligned with strip (no link chrome).
- Player store: reseed clears local cache and replays analysis seed; show loudness dB from SQLite cache when live state is still null; allow first numeric normalization-state update through the short duplicate filter.
- audio_update_replay_gain: resolve loudness from the requested gain when playback URL is not pinned yet.
Improve normalization consistency by separating cache refresh for non-playing tracks, hardening track-id cache lookups, and keeping UI gain state aligned with actual playback. Also reduce startup stalls by preferring non-seekable streaming when format hints are missing and by tuning ALSA/analysis paths to avoid underrun-prone churn.
