librosa.filters.get_window¶

librosa.filters.get_window(window, Nx, fftbins=True)[source]¶

Compute a window function.

This is a wrapper for scipy.signal.get_window that additionally supports callable or pre-computed windows.

Parameters:	window : string, tuple, number, callable, or list-like The window specification: If string, it’s the name of the window function (e.g., ‘hann’) If tuple, it’s the name of the window function and any parameters (e.g., (‘kaiser’, 4.0)) If numeric, it is treated as the beta parameter of the ‘kaiser’ window, as in `scipy.signal.get_window`. If callable, it’s a function that accepts one integer argument (the window length) If list-like, it’s a pre-computed window of the correct length Nx Nx : int > 0 The length of the window fftbins : bool, optional If True (default), create a periodic window for use with FFT If False, create a symmetric window for filter design applications.
Returns:	get_window : np.ndarray A window of length Nx and type window
Raises:	ParameterError If window is supplied as a vector of length != n_fft, or is otherwise mis-specified.
