Methods for creating windows.

Functions

def get_tukey(array: numpy.ndarray, alpha: float = 0.5) ‑> numpy.ndarray

Create a symmetric Tukey window (AKA: tapered cosine window) with same shape as input array. Note: alpha of 0 is a rectangular window, 1 is a Hann window. :param array: input array to get shape from :param alpha: fraction of the window inside the cosine tapered window, shared between the head and tail

def get_tukey_by_buffer_num(array: numpy.ndarray, taper_num: int, alpha: float = 0.5) ‑> numpy.ndarray

Create window with the same shape as input array, tukey tapered on the head and tail with ones in the middle.

Note: alpha of 0 is a rectangular window, 1 is a Hann window. :param array: input array to get shape from :param taper_num: number of points to taper on each side :param alpha: fraction of the window inside the cosine tapered window, shared between the head and tail

def get_tukey_by_buffer_s(array: numpy.ndarray, taper_s: float, sample_rate_hz: float, alpha: float = 0.5) ‑> numpy.ndarray

Create window with the same shape as input array, tukey tapered on the head and tail with ones in the middle.

Note: alpha of 0 is a rectangular window, 1 is a Hann window. :param array: input array to get shape from :param taper_s: duration of taper in seconds :param sample_rate_hz: sample rate in Hz :param alpha: fraction of the window inside the cosine tapered window, shared between the head and tail
