In general, MSVAD would be the wrong way to do this.  To make a voice
changer, you need to get input from a real microphone, not a virtual
microphone.  If you're trying to do this within a single application,
you could write a DirectShow filter for this.

Alternatively, you may be able to use the Virtual Audio Cable
application to do what you want:
