Feature Overview

Feature Overview

Cadence brings a managed local library, native playback, organization, and lyrics into one macOS application. It does not provide a streaming catalog or modify source files selected for import.

Library

• Review files and duplicates before import.
• Copy confirmed media into ~/Music/Cadence.library under stable track IDs.
• Link matching line-timed LRC files.
• Move managed items to recoverable Cadence Trash and restore them later.

Playback

• Use an AVAudioEngine PCM path for supported stereo files.
• Fall back to the system player when the route or format requires it.
• Control playback from Cadence, media keys, Control Center, queue, and Now Playing.
• Inspect source format, sample rate, channels, backend, and output route.

Organization and editing

• Browse tracks, albums, artists, playlists, tags, and smart collections.
• Apply hierarchical tags without changing the audio file's metadata.
• Search the library and follow contextual navigation.
• Edit lyrics, timestamps, and artwork on managed library records.

Interface and accessibility

• System, Light, and Dark appearances.
• First-run guidance plus replayable Help chapters.
• Keyboard navigation, VoiceOver labels, and reduced-motion behavior in the production UI.

For implementation details, use Architecture. For current manual release gaps, start with Troubleshooting and the repository README.
