A module for modifying the voice of a player

I don’t know if it’s the proper section but i’m looking for a server module that allow to apply various effects to a pplayer’s voice before it is sent to the other players, namely:

-Overlay: for simulating radio static, etc…
-Stereo balance (if possible)
-DSP effects

Something like this already exist?

This looks cool, I’d like to see this be made also!

¡A mì tambien!
