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