AudioCheck
Your MP3s, M4B audiobooks, and lectures already live in Files. AudioCheck indexes the folders you choose, streams with live permission checks, and keeps a persistent player while you browse Nextcloud.
We improve this app with real-world use. Bug reports, rough edges, and ideas help — open a GitHub Issue or write to info@software-by-design.de.
What it does
AudioCheck turns folders you already have into a clear library with a persistent player. Every stream and cover goes through live file permission checks — nothing is uploaded elsewhere.
Music library
Tracks, albums, folders, search, and sort — separate roots for music and audiobooks.
Continue listening
Home shelf, dashboard widget, saved progress per file, and a durable cross-device playback queue.
Playlists & Favorites
Built-in Favorites synced with Files stars plus manual playlists you create.
Chapters, speed & formats
Chapter jumps on .m4b and tagged files; MP3, M4A, M4B, and MP4 audio; 0.5×–4.0× playback speed.
Files integration

Built with security first
Single file-access gate, uniform 404 for inaccessible files, no outbound HTTP for playback.
