Granular Synthesis
We will now implement the second voice transformation method described in the Jupyter notebook, namely pitch shifting via granular synthesis.
While the alien voice transformer simply alters the quality of the voice, with a pitch shifter we will be able to move the perceived pitch of the speaker either down (to create a "Darth Vader" sound) or up (to create a "Chipmunks" voice).
We recommend you study the relevant section on the notebook carefully before proceeding, since the algorithmic details are going to be a bit trickier than what we have seen so far; please make sure you understand the theory and that you are comfortable with the offline implementation before tackling the real-time version of the transformer.
May the Force be with you!
