Kylo Ren voice in Star Wars The Force Awakens is very cool. When I watched the movie in 2015, one of the first things that came up to my mind was how to do such voice in Mathematica. At the time Mathematica capabilities to manipulate sounds were very simplistic, and was not possible to do such thing.
I'm far far way to be a sound expert, but I tried do something like this:
file = Import["https://s3-sa-east-1.amazonaws.com/rmurta/murta-audio.wav"]; audioOrg = Audio[file]; audioKylo = AudioPitchShift[audioOrg, 0.9]; audioKylo = AudioFrequencyShift[audioKylo,-200]//AudioAmplify[#, 4]&
Original Murta's record: Murta original
And here is the result: Murta as Kylo
I believe the community can do much better. I'm right?
