When a provider delivers a lossy/unknown stream, the native finalizer preserved the container but kept the requested .flac name, so every metadata/ReplayGain write treated the file as FLAC and failed with "failed to write FLAC metadata: failed to parse FLAC file: fLaC head incorrect" — on the first download, on every retry (the file is never deleted from public storage), on every manual edit attempt, and the history backfill re-probed the same file on every app launch forever. - Finalizer now renames a preserved lossy/unknown container away from its .flac name to match the real content (aac/MP4 -> .m4a, mp3, opus), mirroring the Dart pipeline, so the correct tag writer is picked - EditFileMetadata sniffs MP4 content before taking the .flac branch and reports what is actually wrong (rename to .m4a) instead of the cryptic parse error - The history audio-metadata backfill remembers paths whose probe failed permanently (unparseable content) and stops reselecting them on every launch; transient failures (missing file, unmounted volume) still retry

Extensions
Extensions let the community add new music sources and features without waiting for app updates. When a streaming service API changes or a new source becomes available, extensions can be updated independently.
Installing Extensions
- Open the Store tab in the app
- On first launch, enter an Extension Repository URL when prompted
- Browse and install extensions with one tap
- Or download a
.spotiflac-extfile and install manually via Settings > Extensions - Configure extension settings if needed
- Set provider priority under Settings > Extensions > Provider Priority

FAQ
Why does the Store tab ask me to enter a URL?
Starting from version 3.8.0, SpotiFLAC uses a decentralized extension repository system extensions are hosted on GitHub repositories rather than a built-in server, so anyone can create and host their own. Enter a repository URL in the Store tab to browse and install extensions.
Why is my download failing with "Song not found"?
The track may not be available from your enabled providers. Try enabling more providers under Settings > Extensions > Provider Priority, or install additional download extensions from the Store.
Why are some tracks downloading in lower quality?
Quality depends on what's available from the source and the installed download extension. Check each extension's quality options and service notes in the app.
Can I download playlists?
Yes! Just paste the playlist URL in the search bar. The app will fetch all tracks and queue them for download.
Why do I need to grant storage permission?
The app needs permission to save downloaded files to your device. On Android 13+, you may need to grant All files access under Settings > Apps > SpotiFLAC > Permissions.
Is this app safe?
Yes SpotiFLAC is open source and you can verify the code yourself. Each release is also scanned with VirusTotal (see badge above).
Why is downloading not working in my country?
Some countries have restricted access to certain streaming service APIs. If downloads are failing, try using a VPN to connect through a different region.
Can I add SpotiFLAC to AltStore or SideStore?
Yes! Add the official source to receive updates directly within the app. Copy this link:
https://raw.githubusercontent.com/zarzet/SpotiFLAC-Mobile/refs/heads/main/apps.json
In AltStore/SideStore, go to Browse > Sources, tap +, and paste the link.
