Ultra high-precision tempo detection using multiple analysis methods with weighted consensus. GreenGo snaps to common production tempos and verifies beat phase coherence for accuracy you can trust.

Key Analysis

Multi-signal fusion key detection engine with genre-aware parameter profiles. Combines four independent detection methods and uses auto-genre classification to weight results — the most accurate key detection available in any standalone tool.

  • 4-signal fusion: libKeyFinder + librosa chroma ensemble + STFT-only + sub-bass root
  • Genre-aware profiles: Electronic, Hip-Hop, Pop, Rock & more
  • Auto-classifier detects genre from BPM + spectral centroid
  • Camelot wheel notation (Rekordbox, Serato, VirtualDJ)
  • Open Key notation (Traktor)
  • Enharmonic normalization (flats → sharps)
