Nightingale

Karaoke from any song in your music library, powered by neural networks.

Nightingale scans your music folder, separates lead vocals from instrumentals using the UVR Karaoke model (or Demucs), transcribes lyrics with word-level timestamps via WhisperX, and plays it all back with synchronized highlighting, pitch scoring, key/tempo controls, profiles, and dynamic backgrounds.

Ships as a single binary. No manual installation of Python, ffmpeg, or ML models required — everything is downloaded and bootstrapped automatically on first launch.
