Phase analyzer with fft~ or pfft~

Hello!
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.

– Pasted Max Patch, click to expand. –

</code>
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.
Thanks.
