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
Audio Analysis Enhancements:
- Display codec name and container format
- Show decoded sample format (s16, s32, fltp, etc.)
- Add LUFS integrated loudness measurement (broadcast standard)
- Add true peak measurement (dBTP)
- Detect and count clipping samples per channel
- Estimate spectral cutoff frequency (helps detect fake upscales)
- Show per-channel statistics (Peak, RMS, DR, Clip count)
UI Improvements:
- MetricChip now handles long text with ellipsis
- Constrained max width for better layout
Cache version bumped to 4 to force rescan with new metrics.
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.
The audio analysis card used to read from a persistent cache but offered no way to refresh the result when the underlying file had been re-downloaded at a different quality (for example, re-downloading a track as FLAC after capturing it as AAC). Add an explicit rescan control that clears the cached JSON + spectrogram, reruns the FFmpeg probe and analysis pipeline, and swaps in the fresh data while keeping the loading copy distinct from first-run analysis. A retry button is also exposed in the error card so transient failures do not require navigating away.
All audio_analysis strings now have a Re-analyze / Re-analyzing pair in the ARB catalog so every locale can translate them independently.
