Thanks, that’s very nice of you!
Yes i’ll intent to send the code as soon as i feel it’s ready to. I try to improve on performance while not consuming too much memory, that’s my priority for now! It’s FFT based and it’s very performance intensive as you are well aware, but it could be worse i guess! Ran some tests on a I7 4790 and found that with default project settings on 48K i can run 16 pitch shift instances (parallel) with 1024 window and 4 oversample, without actually hitting the limits of the audio engine. So far so good, but it’s not final result. I just hope i can keep this level up.
No i didn’t mean to beat anybody, it’s just fun and i enjoy working on the bits and pieces of this code. Wish i could spend more time on this, but i’ll find my ways to keep myself focused on this project. If you have better, less performance consuming solutions to FFT’s i’m sure you will be the one who beats me on this 
Yes sir, i absolutely agree It’s fun to work on and many possible uses ahead!
I just hope the implementation will hit the requirements of an acceptable pull request. It’s not an easy task, really gives me the scare
