Hi Jerry, I missed your second paragraph. I read about WaveRT drivers and Vista audio support. Maybe I missed something, but what I read seemed to indicate that Vista's audio enhancements would improve the average user experience with latency, but wouldn't provide a definitive advantage over a tuned Windows XP machine running ASIO drivers on PCI hardware. Am I wrong? - Andy ________________________________ From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Jerry Evans Sent: Sunday, March 04, 2007 6:33 AM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: Anyone here worked with Windows CE? 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: http://cmediadrivers.googlepages.com/. If WaveRT drivers and Vista CoreAudio live up to promise then you might get all you want. Keep us posted!

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?
