Virtual Audio Device Driver - Windows

Windows XP 32/64, Vista 32/64, Windows 7 32/64

Virtual Audio Device/Loopback

Virtual Audio Device driver which provides for Audio Out Device

and Matching Line In device. Basically its a Loopback where we can

play out audio to VIRTAUDIO and read same data back in thru Virtual

LINEIN Device.


Install as System Driver

We will handle code signing to support 64 bit mode

Supported formats:

8000/16/2, 8000/16/1

22050/16/2, 22050/16/1

44100/16/2, 44100/16/1

48000/16/2, 48000/16/1

Volume Control

Multiple Instllations (supporting say 5 virtual LINE IN/LINE OUT)

Must be near realtime (no delay)

This will be a 1-1 mapping, no need to support for multiple connections


Must appear in Windows Sound Control Panel.

Must appear in say GraphEdit, each line in as seperate INPUT.

Source Code should be properly documented.

Sufficient buffering so as to support polling of LINEOUT every 500ms to grab

data. We dont want overrun/underrun on buffers.


We do NOT WANT a directshow filter. If that is what we wanted, we would have posted for such. We know what we need, and why we need it. Directshow filters can not be directly assigned by applications (not ours) to direct output.
