🎵 Voice Note to MIDI
Transform your voice memos, humming, and melodic recordings into clean, quantized MIDI files ready for your DAW.
What It Does
This skill provides a complete audio-to-MIDI conversion pipeline that:
- Stem Separation - Uses HPSS (Harmonic-Percussive Source Separation) to isolate melodic content from drums, noise, and background sounds
- ML-Powered Pitch Detection - Leverages Spotify's Basic Pitch model for accurate fundamental frequency extraction
- Key Detection - Automatically detects the musical key of your recording using Krumhansl-Kessler key profiles
- Intelligent Quantization - Snaps notes to a configurable timing grid with optional key-aware pitch correction
- Post-Processing - Applies octave pruning, overlap-based harmonic removal, and legato note merging for clean output
