How to act as a microphone using DirectShow or something else on windows?

I have googled for a while to find how to create a virtual mic on windows. But I find nothing.
I want to write a program acting as a microphone which can be used in Skype when there is no mic on my computer. So that I can play music from audio files to my friends.

Is it realizable? Can I do it in C++?
If so, Can I do it in directshow? Which Interface should I implement to make a virtual mic filter. Otherwise, what other technology should I study?
If not, why?

TIA!
