I am trying to take a snapshot of an audio signal and convert that into a list
of normalized freq magnitudes. I want the output list to have 8 frequency bands.
I first tried fftb~, but it outputs freq components as audio signals in the amplitude time
domain. fft~ brings things in to the freq domain, but I can't figure out how to
get to the fft bin data to create my list. Also fft~ is using a 512 sample window, so I need to
be able to reduce that to 8 bands.
This seems harder than it should be. Am I missing something?
Any pointers would be appreciated.
