Sound inputs

What is the purpose of Sound inputs in my emotive lamp project?

Sound plays an important part in our everyday lives.
Without sound, it is like painting a picture without color.

Sound affects our reaction in every way,
for example, the sound of a car horn warning of any danger approaching.
When the loud sound waves travels through our ears, our heart pumps extremely fast and the blood flow increases, thus, we react. This is thus, portrayed in the lamp that i'm doing.

I've decided to create an interactive sound file which reacts according to the keys pressed on my keyboard. The different keys will be programmed to create different lighting outputs and vibrating effects on the lamp.

Some visuals to explain what the outcome will be like:

Blinking LED + Sound Input= Emotive Lamp

Here's an example:
