1. A system for controlling a device, the system comprising:
at least one microphone configured to:
detect a sound produced from touching a surface; and
produce an electrical signal from the detected sound; and
at least one processor configured to:
receive the electrical signal from the at least one microphone;
convert the received electrical signal to a spectrogram;
use image recognition to compare the spectrogram to one or more sound profile spectrograms; and
in response to, based on the comparison, the spectrogram meeting or surpassing a similarity threshold to one of the one or more sound profile spectrograms, change at least one characteristic of the device based on a control operation mapped to the one of the one or more sound profile spectrograms.
