Bartlett modifies the buffer to a Bartlett window.

Blackman modifies the buffer to a Blackman window N = size n = element a = 0.16 a_0 = (1 - a) / 2 a_1 = 1 / 2 a_2 = a / 2 w[n] = a_0 - a_1 * cos((2 * pi * n) / N) + a_2 * cos((4 * pi * n) / N).

CosSum modifies the buffer to conform to a cosine sum window following a0.

Hamming modifies the buffer to a Hamming window.

Hann modifies the buffer to a Hann window.

Lanczos modifies the buffer to a Lanczos window w[n] = sinc((2n / N) - 1) N = size n = element k = 2 / N buf[n] = sinc(kn - 1) https://www.wikiwand.com/en/Window_function#/Other_windows.

PlanckTaper modifies the buffer to a Planck-taper window not sure how i got this.

Rectangle is just do nothing.

HammingConst is the hamming window constant.

Function is a function that will do window things for you on a slice.
