The VisualDSP toolset from Analog Devices for their floating-point SHARC processors is probably the best you'll find for realtime audio development.

Does it compare across the board to Visual Studio for Windows? Well, probably not but realistically nothing can. Windows is the biggest single development market there is, so the tools are the best funded.

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! Jerry ----- Original Message -----

    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?
