Nightingale is an open-source karaoke application that turns any song in your music library into a karaoke track using neural networks. It separates vocals from instrumentals (UVR/Demucs), transcribes lyrics with word-level timestamps (WhisperX), and plays back with synchronized highlighting, pitch scoring, and key/tempo controls.
Use cases
- turn my music library into karaoke tracks
- karaoke app with automatic pitch scoring
- separate vocals from instrumentals for singing practice
- get word-level synced lyrics for any song
- host karaoke night from my Plex or Jellyfin library
- self-hosted karaoke server for the whole house
- play UltraStar Deluxe songs with a modern app
When to choose
- you want karaoke from your existing music files, Plex, Jellyfin, or Navidrome library without manual prep
- you need automatic vocal separation and word-level lyric alignment including CJK songs
- you want a self-contained app with pitch scoring, key/tempo shifting, and player profiles
- you want a self-hosted web mode so phones, tablets, and TVs can join from a browser
When to avoid
- you need a code-signed installer or strict corporate security policies (the app is unsigned on macOS)
- you only want a lightweight lyrics player without ML analysis overhead
- you have no GPU and need fast analysis (CPU mode works but is slow)
- you need a cloud-hosted multi-tenant karaoke service
