The only functions with builtin windows are the Nyquist fft functions.
The only way to get your own window function is to read the soundfile
(s-read filename [:time-offset offset] [:dur dur])
To get different window types you have to read the file with overlapping
blocks (windows) and fade from one to the next e.g. with with 'mult' and 'pwl'.
