Hello, I would like to know if it is possible to have the Arduino recognize different sounds and react to them. I would be using a surround sound system to play the sounds off of a cd to start with. So I would just use one set of wires that would normally be sent to a speaker. What hardware would I need to use to "teach" the Arduino to recognize a sound(S) and react to it? Also how hard would the programing be?
Thanks!
A lot depends on a "sound" and type of arduino. I build a project with UNO, and later translate it to Leonardo - voice recognition:

length limited by 1 sec, at freq. range 2 kHz max (which is o'k for voice).
Also how hard would the programing be?
Depending. On what the sounds are and what number of false responses are acceptable it ranges from difficult to impossible.
