@audio/mir-tonnetz\n\n> Tonal centroid (Tonnetz) — projects a 12-bin chroma vector onto three interval circles (fifths, minor thirds, major thirds), giving a 6-D harmonic-change feature (Harte, Sandler & Gasser, 2006).\n\n`npm install @audio/mir-tonnetz`\n\n```js\nimport tonnetz from '@audio/mir-tonnetz'\n\nlet tz = tonnetz(chromaVec)\n// Float32Array[6] — [fifths.sin, fifths.cos, minor3rds.sin, minor3rds.cos, major3rds.sin, major3rds.cos]\n```\n\nNo options — `tonnetz()` takes a length-12 chroma vector (any normalization) and returns a fixed 6-D point. Consecutive Tonnetz points that jump far apart flag harmonic change (chord/key boundaries); a static point means harmonic stasis. Zero-energy chroma maps to the zero vector.\n\nAlso exported as an `audio.js` stat manifest (`./audio`) — Tonnetz frames over time (via `@audio/mir-chroma` internally) plus their mean.\n\nPart of [@audio/mir](https://github.com/audiojs/mir).\n","readmeFilename":"README.md","homepage":"https://github.com/audiojs/mir#readme","repository":{"type":"git","url":"git+https://github.com/audiojs/mir.git","directory":"packages/mir-tonnetz"},"bugs":{"url":"https://github.com/audiojs/mir/issues"}}
