A Hann window is a taper function defined as w(n) = 0.5 * (1 - cos(2πn/(N-1))) for n = 0..N-1, where N is the window length. Parameters: N (integer ≥ 2, window length), n (sample index). Persistence mechanism: standardized as a mathematical formula in signal processing libraries and documentation. [formal: hann window is | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]
