Changelog

3.0.0

Breaking: ESM-only. require() no longer works.

34 window functions (was 18): added connes, powerOfSine, generalizedNormal, planckTaper, exponential, hannPoisson, cauchy, rifeVincent, confinedGaussian, kaiserBesselDerived, dolphChebyshev, taylor, dpss, ultraspherical, parzen, bohman
Quantitative metrics: enbw, scallopLoss, cola
Individual files: import hann from 'window-function/hann'
Default + named exports: both import hann from and import { hann } from work
TypeScript declarations included
Scientific SVG plots for all windows (time domain + frequency response)
Consolidated to ESM ("type": "module")
Single util.js for shared helpers and utilities
Zero dependencies (fourier-transform is devDependency for plot generation only)

- const hann = require('window-function/hann')
+ import hann from 'window-function/hann'

The per-sample API fn(i, N, ...params) → number is unchanged.

18 window functions: rectangular, triangular, bartlett, welch, hann, hamming, cosine, blackman, exactBlackman, nuttall, blackmanNuttall, blackmanHarris, flatTop, bartlettHann, lanczos, gaussian, tukey
