    Hi all,Is there anyone know how to modify MSVAD sample to make a voice 
changer?Thank you.
    Some docs on the web say modify CopyFrom or CopyTo function in the 
BaseDma.cpp can do this,
    But I don't know how to do it,Could you please tell me how to start?

  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:
