Virtual Audio Device
Virtual Audio Device driver which provides for Audio Out Device
and a Line In device. When audio is playing out it is looped back in on the Line Device. We will access this LINE in device either thru Directshow or other windows means.
Install as System Driver
We will handle code signing to support 64 bit mode
Must be near realtime (no delay)
Ability to support 4 virtual pairs
Must appear in Windows Sound Control Panel.
Must appear in say GraphEdit, each line in as separate 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,
this must be a valid windows system driver.

While that product has more than we need, it is what we want.

To date we have been led on by two developers who have not been able to do the work, or complete the job.
