Signature
def _calc_dual_canonical_window(win: np.ndarray, hop: int) → np.ndarraySummary
Calculate canonical dual window for 1d window win and a time step of hop samples.
Extended Summary
A ValueError is raised if the inversion fails.
This is a separate function not a method, since it is also used in the class method ShortTimeFFT.from_dual().
