Downloaded this SAT LIVE, and started playing with it. It seems a lot easier to use than other dual FFT software I have messed with. They give a 30 day demo trail with full functionality, and offer it for $220, about 1k less than SMAART. I will be measuring, time aligning and other fun stuff to optomise what I have, better design xovers, and the like. A lot to learn about, but I am hoping it can be a useful tool.
