What libraries should be used to write a virtual microphone driver?

Question

C++ / C#

Hello, tell me how to write a virtual microphone driver, or rather a program to broadcast music, and also at any time, for example, press a button and your voice will start to be broadcast (the microphone turns on real and starts broadcasting), I will be grateful in advance for the answer.
PS Ready-made solutions are not interesting, only the names of libraries and some general advice.

Answer 1

For Windows, everything is on the NT libraries, and compile WinDDK.
