showfreqs and various other audio viz filters to create cool spectrum visualizations for my self-released music.
Going through the documentation, I see that there's a multitude of
win_funcs you can use with
showfreqs (and others):
I tried reading about these different windowing functions on wikipedia: https://en.wikipedia.org/wiki/Window_function
While I understand generally that you choose a windowing function based on how you want to handle spectral leakage, I can't really understand the math that's involved here... it's over my head.
So... my question really boils down to:
What's the right windowing function to use for visualizing music? Is there a best practice here?
hanning (the default) seems to work ok... I tried a few others but I'm having trouble actually observing what the differences are between them...
