Phase analyzer with fft~ or pfft~

    Jul 08 2013 | 8:53 am
    I want to build a phase analyzer patch with fft and cartopol but i think i'm missing something about phase response theory because all i see is a random response.
    in this patch i modified the plot~ help file.
    Can you point the errors in the patch?
    I have to use a different source than noise~ to see plots like this?
    Any help would be appreciated.
