Pfft~ Pitch Shift inside Gen~
Apr 02 2015 | 3:38 am
Hey there Jean,
I'm building a pitch shifter which performs in gen~ via pfft~ to optimize performance.
I wanted to tag you in the forum post given your experience in the field of spectral analysis. I have gained quite a bit of knowledge from your previous works and posts concerning FFT.
Currently, I believe to have properly determined bin frequency centre and then real frequency, however I have hit a roadblock in respect to outputting the shifted bin index and converting the shifted real frequency back to phase for fftout~.
I have attached a few images of the patch, specifically inside the pfft~ and the embedded gen~ code. Currently shifting ratio comes though pfft~ input 2 (@comment ShiftRatio)
If anyone could chime in with some insight I would really appreciate it. I have the feeling I'm close to success but over looking something simple!
