Re: PitchDetection: UGen Tartini gives different results on Win and Mac

I think you can use otool to change library path(s).
I'd also consider building fftw statically... The last time I tried it
wasn't too difficult, here's my custom homebrew formula to build fftw
(shared, but should be straightforward to change to static):
