What nightingale-karaoke does

The skill covers Nightingale, a Rust and Bevy application that scans a local music folder and prepares songs for karaoke. It can split vocals from backing audio with UVR Karaoke or Demucs, retrieve timed lyrics through LRCLIB, and use WhisperX to create word-level timing. Playback includes lyric highlighting, pitch scoring, player profiles, and shader or video backgrounds.

Its guidance includes setup, first launch, configuration in ~/.nightingale/config.json, profiles in ~/.nightingale/profiles.json, and keyboard or gamepad controls. The first run fetches ffmpeg, Python 3.10, PyTorch, and the required ML models. Building from source requires Rust 1.85+; Linux also needs libasound2-dev libudev-dev libwayland-dev libxkbcommon-dev. CPU processing takes ~10–20 min/song, so hardware choice affects the wait for analysis.

What it helps with

  • build a Rust karaoke app with Bevy
  • separate vocals from backing audio
  • create timed lyrics from a song
  • score a singer’s pitch in real time
  • configure player profiles and visual backgrounds

Example prompts for the agent

  • Build a Rust and Bevy karaoke app following the Nightingale design.
  • Add Demucs vocal separation and WhisperX transcription with timed words.
  • Configure player profiles, pitch scoring, and a video background for playback.
