@audio/pitch-yin\n```\n\n```js\nimport yin from '@audio/pitch-yin'\n```\n\n**de Cheveigné & Kawahara, 2002.** The reference algorithm for monophonic pitch estimation. Most cited, most tested, most robust.\n\n```js\nlet result = yin(samples, { fs: 44100 })\n// → { freq: 440.1, clarity: 0.97 } or null\n```\n\n| Param | Default | |\n|---|---|---|\n| `fs` | `44100` | Sample rate (Hz) |\n| `threshold` | `0.15` | CMND threshold — lower = stricter, fewer detections |\n| `minFreq` | — | Minimum frequency (Hz); also uses more of the frame for low pitches |\n| `maxFreq` | — | Maximum frequency (Hz) |\n\nPass the expected range when known: `yin(samples, { fs, minFreq: 60, maxFreq: 520 })`. Besides rejecting out-of-range results, `minFreq` lets YIN use a longer comparison window and improves low-pitch detection near onsets.\n\n**Use when:** General-purpose monophonic pitch tracking — speech, singing, solo instruments. The most reliable choice when in doubt.
\n**Not for:** Polyphonic audio (returns dominant or null), real-time with hard latency budgets (needs full window).
