[pd] hanning window + fft

Actually anything (links, explanations, etc) that explains or details FFT as
it relates to Pd would be great... the example patches are a bit cryptic, or
sometimes jump a bit too quickly, at least for me.  I want to eventually
generate visuals based on obtaining frequency data from sound, but I just
couldn't get my mind around fft~, rfft~ etc. so I am going cheap using
bandpass filters now which is not really what I wanted.  (Sidenote - does
anyone know how other artists are accomplishing this?  I assumed they were
using FFT)

I know this is a fairly advanced topic but I'd really love to figure out how
to make it work.

Glad this came up!!
