Well, there are two companies that I can think of to get you going on this. First, Turtle Beach Softworks has announced a 56k card for the AT. I don't know the price off hand, but it's a place to start. Second, a company called Spectral Synthesis makes a system based on TI's 32C020. Each of their cards has two DSP's on board, and you can connect up to seven cards in a system. They can get you going for about $2000, but when I last saw their software, about eight months ago, they were not ready to ship just yet. Their software is called AudioCAD, and basically it lets you connect fundamental blocks (mixers, amplifiers, etc.) graphically under windows, then it compiles the code and assigns it to the bank of DSP's. Their big goal is real time processing, so the have a neat set of resource allocation routines, and process scheduling system to best use however many DSP's you have in your system. A full blown system is about $10k. Oh, and you can write your own primatives too. -Dean Swan dean@sun.soe.clarkson.edu
