Hello list,
I am planning to write an application which intercepts data from microphone, 
processes it, then hands over to upper level applications. Ideally,
the program should
present itself as a device so that if a user chooses to use it instead of 
standard audio input hardware, it starts doing its job. Target
platforms are XP,
2003 and later. I have no control on applications using audio devices.
I'm an experienced Windows/C++ programmer but completely new to device driver programming. Please point me to the right direction where I can get a quick 
start (sample code, articles, advice, etc). Greatly appreciated.

TIA.

Will Xu
