Hi,

Im looking at fft stuff, and I think I need to learn how to peek a window (hanning/blackmann etc)
into a buffer, but the math behind this look scary.

Any tips?

I did a little exercise the other day and came up with an abstraction to do just that. I got the formulas from wikipedia. Hope this is helpful. let me know if there are any bugs.

thanks,

can something decent be done with some oscillators and filters, like triangle~ and rampsmooth~/slide, or envelopes like techno~ or adsr~, or something?
