I am looking for a driver than can appear as a sound device to the
system but be configurable to send the wave output to a file instead of
an actual device and have the ability to create multiples of these
devices.

Hello Yura,
thanks for your reply. Our application now use Wave-in and wave-out so I
understand that we can use your driver.
Can you provide me the demo and details to use? Can you also quote me?
