Windows APO


I have a C/C++ code for real time audio processing and I want it to run on a windows machine - without a DAW.
The goal is to run any windows app (spotify, youtube, browser, VLC, foobar or other player) - via the ‘APO’ of Windows.

The chain should be:
Any app playing music --> Windows APO in --> my code processing --> Windows APO out --> Speakers (or sound card) out

This way I can process any app and send it to any available output on the PC.

Is any one experienced with that?
