I’m trying to achieve an effect that I could’ve done before in the native Mac Auxiliary Tool named Repeat After Me. What I want to do is pitch down a whole audio to a certain frequency (seen in https://www.youtube.com/watch?v=Cma-WdKsxRs)
“Repeat After Me” is a completely different kind of app than Audacity. To do what you previously did in “Repeat After Me” you will need to use “Repeat After Me”. Audacity is NOT a speech synthesiser.
Grallion2 is a free pitch-shifting plugin.
It can make everything one pitch, (robotic monotone). https://youtu.be/28ckb6ztHAc?t=20
I’ve used it in Audacity on Windows, apparently it’s available for Mac.
