I asked a similar question a while ago but I didn’t know very much, so I wasn’t able to be specific enough.
I want to write a program that takes input from my microphone, processes it, and then sends the output to a fake “virtual microphone” as if the processed sound I created was what a microphone was hearing. I would then like to be able to use this virtual microphone with any application that supports choosing your microphone input (pretty much any well written software) as a valid microphone. So what the application “hears” will be my processed version of the microphone input.
I’m working with Portaudio in C and I can capture from the mic, process, and send out to the speakers just fine. Now I need to replace my real speakers in the application with the phony microphone. Windows seems to have some APIs for this.

So my sink pin will be the real microphone and I will have to create a NEW source pin that should be visible to other applications. How would I go about doing this? I’m having difficulty finding code samples or really even any very informative documentation.
Language: C
OS: Windows 7
It is possible to use the Windows Stereo Mix for that. Then you can open the virtual device in loopback mode and record what the microphone hears with programming
