Requested by @okinaau in issue #242 — brings back the ability to
download tracks in lossy format for users on low storage devices.
HIGH quality fetches the AAC M4A stream directly from the Tidal server
(no lossless download + re-encode), then converts to MP3 or Opus via
FFmpeg based on the tidalHighFormat setting (mp3_320, opus_256, or
opus_128).
- go_backend/tidal.go: restore outputExt .m4a, filename logic,
duplicate-check guard, HIGH M4A lyrics/LRC handling, and
bitDepth=0/sampleRate=44100 for HIGH quality result
- settings.dart + settings.g.dart: re-add tidalHighFormat field
(default mp3_320) with JSON serialization
- settings_provider.dart: re-add setTidalHighFormat(), remove
migration that force-migrated HIGH to LOSSLESS
- download_queue_provider.dart: restore HIGH conversion logic for
both SAF and non-SAF paths using FFmpegService.convertM4aToLossy
- download_settings_page.dart: restore Lossy 320kbps quality tile,
format sub-picker tile, _getTidalHighFormatLabel helper, and
_showTidalHighFormatPicker bottom sheet
- l10n: add 10 keys (downloadLossy320, downloadLossyFormat,
downloadLossy320Format, downloadLossy320FormatDesc, downloadLossyMp3,
downloadLossyMp3Subtitle, downloadLossyOpus256/Subtitle,
downloadLossyOpus128/Subtitle) to ARB and all 13 generated files
When enabled, playlist downloads are placed inside a subfolder named
after the playlist before the normal folder organization structure
(e.g. Playlist/<artist>/<album>/). The setting is a no-op when folder
organization is already set to 'By Playlist'. Includes model field,
JSON serialization, settings notifier, download queue path logic,
UI toggle in download settings, and localizations for all 13 languages.
Add a new 'Auto Scan' setting under Local Library with four modes:
off, every app open (10min cooldown), daily, and weekly. The app
uses WidgetsBindingObserver to trigger incremental scans on launch
and when resuming from background, respecting the configured
cooldown based on the last scan timestamp.
- Add _convertToAlac() and _convertToFlac() in ffmpeg_service with
single-pass FFmpeg encoding, metadata tags, and cover art embedding
- Wire lossless formats (ALAC, FLAC) into single-track convert sheet
with dynamic format list based on source format, hidden bitrate for
lossless targets, and lossless hint text
- Add lossless conversion to batch convert UI in downloaded_album,
local_album, and queue_tab screens with lossy-source filtering
- Fix M4A quality probe in Go backend: increase audio sample entry
buffer from 24 to 32 bytes, read sample rate from correct offset
(bytes 28-29) and bit depth from samplesize field (bytes 22-23)
- Add l10n keys for lossless confirm dialogs and hints (en, id)
Add 'Auto-fill from online' expandable section to the metadata editor
that lets users choose exactly which fields to populate from online
metadata search. Users can select individual fields via filter chips,
use 'All' or 'Empty only' quick-select buttons, then tap 'Fetch & Fill'
to search metadata providers and fill only the selected controllers.
The search uses existing searchTracksWithMetadataProviders API with
ISRC-preferring best-match selection. Extended metadata (genre, label,
copyright) is fetched via Deezer extended metadata API when available.
Cover art is downloaded from the match's cover_url. All results are
previewed in the editor before saving — nothing is written to the file
until the user taps Save.
Add 21 new l10n keys (editMetadata* namespace) for all UI strings.
Add LocalTrackRedownloadService with confidence-scored metadata matching
(ISRC, title, artist, album, duration, track/disc number, year) to find
reliable online matches for locally-stored tracks.
Wire up 'Queue FLAC' selection action in both local_album_screen and
queue_tab (library tab). Shows progress snackbar during resolution,
skips ambiguous or low-confidence matches, and reports results.
Add Indonesian (id) translations for all queueFlac l10n keys.
- Add YouTubeQualityOpus320 constant and opus_320 parser case in Go backend
- Expand opus supported bitrates to [128, 256, 320] across Go, Dart settings, and UI
- Update default YouTube Opus option from 256 to 320kbps
- Remove Tidal HIGH (lossy 320kbps) quality from Go backend, settings model,
settings provider, download queue provider (both SAF and non-SAF paths),
settings UI (quality option, format picker, helper methods), and l10n keys
- Add settings migration v6: auto-migrate users with audioQuality=HIGH to LOSSLESS
- Update and add Go test cases for opus_320 and adjusted max bitrate
- Regenerate l10n files, remove 10 unused downloadLossy* l10n keys
Parse .cue files in library scanner (Go + SAF) to display individual
tracks instead of one large audio file. Add FFmpeg-based CUE splitting
to extract tracks into separate FLAC files with embedded metadata and
cover art.
- Go: CUE parser, two-pass scan (CUE first, skip referenced audio),
virtual paths (cue#trackNN) for DB UNIQUE constraint, audioDir
override for SAF temp-file scenarios
- Android: SAF scanner recognizes .cue in both full and incremental
scan, copies .cue+audio to temp for Go parsing, unchanged-CUE audio
sibling dedup, parseCueSheet handler resolves SAF audio siblings
- Dart: FFmpegService.splitCueToTracks, CUE split UI in track metadata
screen, persistent output dir for SAF splits with write-back
- CUE virtual path normalization across fileExists/fileStat/deleteFile/
openFile; play/share/open blocked for virtual tracks with guidance to
split first; delete only removes DB entry, not shared .cue file
- iOS: parseCueSheet handler
- Localization: 12 new CUE-related strings
