- Extract _formatDownloadProgressLabel() for cleaner code
- Show received/total size when bytesTotal is available
- Estimate total size from progress when only bytesReceived is known
- Add text overflow handling with ellipsis
New lyrics providers using Paxsenix API:
- Spotify: Synced lyrics from Spotify
- Deezer: Synced lyrics from Deezer
- YouTube: Lyrics from YouTube
- Kugou: Lyrics from Kugou (Chinese service)
- Genius: Plain text lyrics from Genius
Implementation:
- Add lyrics client implementations for all providers
- Smart search result scoring based on track name, artist, and duration
- Support for both synced (LRC) and unsynced lyrics formats
- Fallback search with simplified track names and primary artist
UI updates:
- Add provider entries to lyrics priority settings page
- Add display names for new providers in settings
- Replace inline format detection with convertibleAudioSourceFormat()
- Replace inline conversion rules with canConvertAudioFormat()
- Add unit tests for Dolby format detection and conversion rules
Audio Analysis:
- Add rescan capability by bumping cache version
- Display channel layout (stereo, 5.1, etc.) and bitrate
- Use astats filter for more accurate peak/RMS measurements
- Support more formats: mp4, ac3, eac3, mka, wv, ape, tta, aif
- Only report bit depth for codecs that store it (FLAC, ALAC, WAV)
- Validate cache for SAF content:// URIs
Conversion:
- Add AAC as conversion target format
- Recognize ALAC as lossless source
- Prevent accidental deletion when source and target URI match
- Store format and bitrate in database after conversion
Utilities:
- Add audio_conversion_utils.dart for centralized conversion logic
- Add isSameContentUri() helper for safe URI comparison
The HIGH-quality lossy format picker can now produce an AAC/M4A 320 kbps output alongside MP3 and Opus. FFmpegService.convertM4aToLossy/convertAudioFormat, the Dart queue pipeline, the Kotlin finalizer, and the library database format helper all route .m4a through a unified aac codec path and tag the resulting file with the M4A metadata writer. The Lossy Format setting gains a new option, and the track metadata convert dialog lists AAC next to the other targets.
Apple Music lyrics gain a 'eLRC word sync' switch (default off). When disabled the pax-to-LRC formatter strips inline word timestamps, producing line-synced LRC that is safer for players that choke on eLRC; enabling it restores the previous word-by-word behaviour. The change propagates through SetLyricsFetchOptions and invalidates the global lyrics cache on toggle.
Broad l10n migration: roughly 400 previously hardcoded English strings across queue, settings, track metadata, repo, audio analysis, setup and extension screens now live in the ARB catalog, with matching plural/placeholder forms. No behaviour change beyond localisation. Existing and new unit tests (lyrics eLRC toggle and Dart settings round-trip) pass.
Introduce AppRemoteConfigService which fetches a platform/version/locale-aware JSON payload from api.zarz.moe/v1/spotiflac-mobile/config and caches it in SharedPreferences. main_shell shows a one-shot announcement dialog (respecting dismissible, CTA, time window and version gates) when no update prompt is pending; dismissed IDs are persisted so each announcement surfaces only once.
Tweaks bundled in: the service health dot loses its blur halo in favour of solid Material 3 tones, and AppInfo gains the remote config endpoint constant. The share listener and SAF migration hook stay synchronous inside the post-frame callback so share-intent URLs never race the network-bound checks.
New unit tests cover the announcement CTA/active-window rules.
Bump the history schema on both the Kotlin finalizer and the Dart database to v9, adding bitrate (kbps) and format (codec label) columns, and let the download flow fill them from backend/probe metadata so lossy downloads keep a 'AAC 256kbps' label instead of falling back to the stored placeholder. Library filtering and the track metadata screen now read format/bitrate directly from those columns, which also fixes mis-tagged quality badges after re-downloading a track at a different format.
Additional fixes bundled in: EditFileMetadata now routes ReplayGain writes through the M4A path whenever the file starts with ftyp (fixing .flac files that actually hold MP4 containers); GetM4AQuality falls back to the first trak/mdia/mdhd duration when mvhd is zero so EAC3 streams no longer report 0s; and both Kotlin and Dart reject bitrate values below 16 kbps to prevent probe noise from surfacing as '0 kbps' labels. New unit tests cover the EAC3 mdhd fallback and the mis-named M4A replaygain path.
GetM4AQuality now recognizes fLaC, alac, ec-3, ac-3, and ac-4 sample entries and parses the MP4 FLACSpecificBox so library entries carry the real codec rather than the container extension. The AudioQuality struct exposes Codec and Bitrate fields (with an estimator for compressed streams), and ReadFileMetadata publishes format + audio_codec so Flutter and Kotlin can make format decisions based on the actual stream.
Downstream: library_scan labels M4A-family items as flac/alac/eac3/ac3/ac4/m4a, zeroes the bitrate for lossless formats, and the filter UI + quality badges use the codec-derived format instead of only the file extension. Scans and SAF importers also accept .mp4 and .aac file extensions. New unit tests cover codec name mapping and MP4 FLACSpecificBox decoding.
Add a pair of floating quick-scroll buttons on the library tab so long lists become easier to navigate. The buttons sit above the bottom navigation (or the selection toolbar in selection mode), fade in and out based on the active page's scroll metrics, and share their scroll-target keys per filter mode so switching filters does not carry over the previous page's scroll state.
Prevent premature 'downloading' status before actual byte transfer
starts, and cache async provider values to avoid UI flicker during
queue library reloads.
Progress pipeline:
- StartItemProgress now initializes with 'preparing' status instead
of 'downloading'
- SetItemProgress ignores synthetic pre-download progress updates
while status is still 'preparing' (no byte data yet)
- DownloadService reads backend status field and propagates preparing/
downloading/finalizing to native worker item snapshot
- Dart progress stream maps 'preparing' to DownloadStatus.downloading
with progress 0.0 (indeterminate spinner)
Queue tab:
- Add _queueLibraryCountsCache and _queueLibraryPageDataCache to
retain last successful data during FutureProvider refetches
- Prevents empty-state flash when loadedIndexVersion bumps trigger
provider invalidation
- Caches trimmed to max 24 entries via FIFO eviction

backed pagination using ATTACH DATABASE to join library and history
tables in a single UNION ALL query.

with indexes, backfill from existing data
- Add getAlbumTracks, findByTrackAndArtist, getGroupedCounts,
existsTrack, findExistingTrack, existingTrackKeys batch lookup

Library database (v7 -> v8):
- v8: add library_path_keys table for cross-DB dedup
- Add getQueueTrackPage, getQueueCounts, getQueueAlbumPage with
ATTACH DATABASE for cross-DB UNION ALL queries
- Dedup local items against history via path_keys JOIN
- All write/delete paths maintain library_path_keys consistency
Download history provider:
- Load only 100 recent items into state.items at startup
- Store lookupItems as immutable List field instead of recomputing
from maps on every access
- Add async fallback to DB in _putInMemoryHistory for items outside
the 100-item window
- Add downloadHistoryPageProvider, downloadHistoryGroupedCountsProvider,
downloadedAlbumTracksProvider, downloadHistoryBatchExistsProvider
- Add catchError to adoptNativeHistoryItem async block
- Fix removeBySpotifyId to query actual DB count instead of decrement
Screen migrations:
- album/artist/playlist/home screens use async DB lookups instead of
sync in-memory state for track existence and playback resolution
- downloaded_album_screen uses downloadedAlbumTracksProvider
- library_tracks_folder_screen uses downloadHistoryBatchExistsProvider
for skip-downloaded checks and cover resolution
Replace the full in-memory List<LocalLibraryItem> in LocalLibraryState
with a lightweight lookup index (ISRCs, matchKeys, filePathById) and
database-backed FutureProvider.family pagination providers.
Database changes:
- Add library schema v7 with normalized lookup columns (track_name_norm,
artist_name_norm, album_name_norm, album_artist_norm, match_key,
album_key) and corresponding indexes
- Backfill normalized columns on migration from v6
- Add getPage, getPageCount, getAlbumPage, getAlbumCount, getLookupIndex,
getCoverPaths, getByFilePath, findFirstByTrackAndArtist DB methods
Provider changes:
- LocalLibraryState no longer holds items list; uses totalCount and
loadedIndexVersion for change tracking
- Deprecate synchronous getByIsrc/findByTrackAndArtist (return null);
add async findExistingAsync, getByIsrcAsync, getById on notifier
- Add localLibraryPageProvider, localLibraryAlbumPageProvider,
localLibraryAllItemsProvider family providers for paginated access
- Add localLibraryCoverProvider and localLibraryFirstCoverProvider
for async cover path resolution from DB
Screen migrations:
- album/artist/playlist screens use findExistingAsync for playback
- library_tracks_folder_screen uses async cover providers and
existsInLibrary for local library indicator
- queue_tab watches localLibraryAllItemsProvider instead of state.items
- library_settings_page uses state.totalCount
- playback_provider uses findExistingAsync
Track metadata screen:
- Replace pushReplacement navigation with in-place state swap using
AnimatedSwitcher for smooth cross-fade transitions on track swipe
- Add metadataLoadGeneration counter to prevent stale async callbacks

network via CachedCoverImage fadeInDuration/fadeOutDuration params)
- Refactor track metadata swipe navigation from push+pop to
pushReplacement to prevent route stack accumulation
- Convert adjacentHorizontalPageRoute to MaterialPageRoute subclass
to support pushReplacement with proper transition semantics
- Add five new metadata completeness filters: missing track number,
missing disc number, missing artist, incorrect ISRC format, and
missing label
- Expose trackNumber, discNumber, isrc, and label on
UnifiedLibraryItem for filter support
- Tighten metadata completeness definition to include all new fields
All search, metadata, and download providers are now exclusively
supplied by extensions. The built-in provider registry that previously
exposed Deezer/Tidal/Qobuz as hardcoded providers is fully removed.
Removed across Go, Dart, Kotlin, and Swift:
- BuiltInProviderSpec class, registry, and all accessor helpers
- SearchProviderAllJSON, GetBuiltInProvidersJSON, ParseProviderURLJSON,
ParseDeezerURLExport Go exports and their platform channel bindings
- Built-in provider items in search dropdown, service picker, and
provider priority UI lists
- provider_ui_utils.dart helper file
Deezer metadata enrichment (ISRC lookup, extended metadata, cover
upgrade) remains fully functional through direct DeezerClient calls
in the download pipeline — these are not part of the provider
registry and are unaffected.
Mark deezer as a retired built-in metadata provider so stale user
priority lists are cleaned up on next launch.

Delete the entire Qobuz downloader implementation (qobuz.go, qobuz_test.go)
including all API clients, search, metadata, download, and track matching
code. Empty the builtInProviderRegistry now that all built-in providers are
retired. Remove Qobuz-specific exports (SearchQobuzAll, GetQobuzMetadata,
ParseQobuzURLExport) and the downloadWithBuiltInQobuz adapter. Stub out

construction into normalizeExtensionDownloadResult/overlayExtensionDownloadMetadata
helpers with AlreadyExists support and ISRC indexing. Switch download mirrors
to DoRequestWithUserAgent for ISP blocking detection. Add 50+ new
localization keys and accessibility labels across all supported locales.
Replace hardcoded Tidal/Qobuz switch/case with builtInProviderSpec registry
pattern. Unify searchTidalAll/searchQobuzAll into searchProviderAll,
getDeezerMetadata/getTidalMetadata/getQobuzMetadata into getProviderMetadata,
and parseDeezerUrl/parseQobuzUrl/parseTidalUrl into parseProviderUrl. Remove
extension-specific getAlbum/Playlist/ArtistWithExtension in favor of generic
