I want to be able to store some sampled sounds, compare them to live samples and trigger an event when they are the same ...
Example - Save the sound of a footstep being made on a gravel path (in fact several at different attenuations) and detect and trigger when a fresh footstep is heard. A fairly simple security application but hopefully reasonably foolproof. It has to be a tiny self contained circuit that can be reproduced cheaply - obviously dead easy to do with a PC and a speech recognition package but how do I do it all in a tiny module?
Any ideas on how to do that please or pointers towards anything that does that job that pre exists?
Any guidance much appreciated - thanks
