TS implementation of the YIN algorithm for fundamental frequency detection

YIN

Faithful YIN algorithm implementation for fundamental frequency estimation according to the seminal paper and nothing else. Deviations from paper are documented in the code.

Usage

In node.js:

const yin = require("./dist/cjs/yin.js").default;
// sine wave with f0 = 440 Hz and sample rate of 8000 Hz sampled for 1024 samples
let signal = Array.from({length: 8000}, (_, i) => Math.sin(2 * Math.PI * 440 * i / 8000));
console.log(yin(signal, 8000, 0.2))

Output:

440.64565401846073
