Transform your music library into a complete karaoke experience with AI-powered vocal separation and real-time pitch scoring. This innovative software uses neural networks to isolate vocals from any song, creating instant karaoke tracks from your existing music collection.

Key features include:

Intelligent stem separation using UVR Karaoke model or Demucs to isolate vocals from instrumentals with adjustable guide vocal volume
Word-level lyrics transcription via WhisperX that aligns every word to the audio timeline, with fallback to LRCLIB database
Real-time pitch scoring that rates your singing performance with star ratings and maintains per-song scoreboards
Multiple player profiles to track separate score histories for different singers
Video file support for .mp4 and .mkv files with automatic vocal separation while displaying original video as background
Dynamic visual backgrounds including GPU shader effects (plasma, aurora, nebula), Pixabay video loops, or source video content
Full gamepad support for menu navigation, song selection, and playback control using D-pad, sticks, and face buttons

The software ships as a single self-contained binary that automatically bootstraps ffmpeg, Python, PyTorch, and ML models on first launch - no complex installation required. Works across Linux, macOS, and Windows with GPU acceleration via CUDA or Metal when available, plus CPU fallback for universal compatibility.
