Phase/bang in Audio Analysis

Hi (and bear with me)
create a Audio Analysis node and hit F1, now select the SplitAudioAnalysis and hit F1 again.
There are two different help patches one with the old bang/phase used, the other without, and the pins are of course useless because of the missing fftw library.
I am trying to get some kind of beat phase function, before I go on patching is there a way to get it already, or is it possibl eo tjust download the fftw library and place it somewhere… or?
