Hi all,

Having just gone through another frustrating afternoon trying to reduce
Windows audio latency, I am motivated once again to think of
alternatives for real time audio algorithm development. I have a couple
applications where a minimum 4.5 millisecond latency is just not

I will probably have to use standalone DSP cards for development in
order to avoid this problem, but the development tools on such boards
just can't compare to Visual Studio.

I have thought before of building a Windows CE target using a standard
Pentium motherboard, and cross developing from a host Windows XP
machine. I've heard that the Visual Studio tools for this sort of cross
development are pretty good. I would imagine that Windows CE could be
configured to have much lower latency than Windows XP.

The problem is that the audio driver model is different, and I am afraid
that finding a Windows CE driver for multichannel audio IO would be
impossible, and that developing a driver myself would be very time

Has this idea occurred to anyone else? Is it even feasible? Has anyone
succeeded? Does anyone have opinions on related subjects?
