Project Detail

Description

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.

Requirements:

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 Installations (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
mixing.

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.

A comparable product: http://software.muzychenko.net/eng/vac.html

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

Please only respond if your are capable of doing the work, can do the work on time, have references.

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