(voice-change-o-matic) Documentation? How to add new voice filters?

[poVoq]

Is there somewhere an explanation how to add new filters?

Something like a female to male or robotic voice filter or so?

Thanks :)

Also:

I am wondering if there is some documentation, or some guide on how to integrate this into another webapp. Like a voice-chat solution, or something like Mozilla's Hubs social VR chat.
