Audio project - 2D speaker array and mic array

Depends on the work you want to move into the FPGA. I doubt, that the CPU will have enough power to do that. I worked on line arrays already as well as wave field synthesis (www.irt.de) and found the linearisation of the microphones will have to be performed before analyzing thier data in order to be able to obtain useful results. This all required some FIR filtering in parallel which was best done in FPGAs. Also microwave arrays and matrix led arrays with IR diodes for laser impulse reception work this way. Allthough they come with similar band widths they required an FPGA though.
