If good tools & v. low latency are the issue then consider OSX. PPC or Intel
both have excellent prosumer hardware available plus Apple CoreAudio is very
easy to use. You should be able to reliably work with 64 sample buffers.
Or try Vista, a 25 buck Terratec soundcard and this BSD licensed driver:

live up to promise then you might get all you want.
Keep us posted!

Subject: [wdmaudiodev] Anyone here worked with Windows CE?
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?
Thanks!
