I was wondering if anyone could help me with a product i'm undertaking. I need a device that can essentially "learn" a particular sound. E.g. The device starts blank, i place it next to a doorbell, put the device into "learn" mode, ring the bell and the device will learn this sound. Now the device will only activate to the sound of this doorbell and nothing else. I originally thought that neural networks could do this job for me, but i have since been brought to the attention of Digital Signal Processors and the prospect that these would do the job better. However i have very little knowledge in this area and am finding it extremely difficult finding any devices that can do this job. If anyone is able to point me in the right direction to solving the above problem, i would be extremely grateful. Many Thanks, James
