Adau1452 Phase Vocoder/Pitchshift
Hi
Would it be possible to implement a phase vocoder in SigmaStudio with the existing blocks?
I am not sure how to do the complex math, or if a Hanning Window function is avaliable.
Guitar Pitch Shifter - Algorithm
If it is not possible, what would have to be added?
Thanks!

Don't know if this is the same thing but there is a design posted somewhere for a Vocoder. I can't remember where I got it from but do a search for "Vocoder-1452.dspproj".

found it, https://ez.analog.com/message/186270?commentID=186270#comment-186270 it is a zip file attached to a reply from KJBob about halfway down the thread
Hi Phillip
Unfortunately that quite different. I am looking to build a phase vocoder, used for real time pitchshifting and resampling. A normal vocoder splits an audio signal into multiple bands, and then controls thode audio bands with another dpectrum divided input or oscillator.
Ah! OK.
I guess that is also different from a standard time delay as they are available in the Toolbox and perhaps could be used for pitch shifting.
