Hello together,

the implementation of a pitch shifter would be awesome!
I found a website with an implemented pitch shifter in the video player:

https://app.quetschn.academy/

You need to be registered for free than you can have a look at some free videos and the video player.
On the left side is the select box with three different pitch levels.

Finally, here’s an idea of what that might look like in backend and frontend.
