title: How to create a virtual audio device
body: <p>I am working on a project in C# for which I need to create several virtual audio devices. 
  Later I will be doing some switching with them on my own.</p>
  
  <p>Does maybe anyone know a nice library that would allow me to do it problematically on my own. To create instances of audio devices. (commercial is OK, but free .dll would be better)</p>
  
  <p>Another solution, that would be an optional solution, is to find a software that creates virtual audio devices according to my desires.</p>
