Hey all, Does a product currently exist on the market that: Takes two or more microphone inputs and applies noise canceling to them, then provides a noise-suppressed output?

Perhaps with a dsPIC or PIC3= 2. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
