Set window shape in extract_part

[Helen Wright]

Hi there,

I see that the sound.extract_part() function has a parameter for the shape of the window to be used. The default is set to RECTANGULAR. Is it possible to change this? And, if so, what options are available? Thanks in advance

Hi

Yes indeed, the default is listed here: https://parselmouth.readthedocs.io/en/stable/api_reference.html#parselmouth.Sound.extract_part.

It's rather strange that the docs do not have the type highlighted as a link, but here it is, with all the options: https://parselmouth.readthedocs.io/en/stable/api_reference.html#parselmouth.WindowShape

These are the same options as in Praat, but I cannot find any Praat documentation on the exact shape of these windows:

But you could have a look here for the programmatic definition of all these windows: https://github.com/YannickJadoul/Parselmouth/blob/4485336c7c5ea017fc5a02657990d0c791f4ee9f/praat/fon/Sound.cpp#L1016-L1093

Or of course just try out on an all-1 sound fragment, that should also work.

Kind regards

Yannick
