Visualising the Auditory System

 
The Design is based on the Cochlea, the part of the auditory system that converts mechanical vibrations into electrical signals that get passed to the brain.

The Cochlea is split up into 25 frequency bands known as the Bark Scale. These are represented by strips of colored LEDs.

The audio feed is analysed in real time in MAX using a fourier transform to separate the audio into different frequency bands.

This information is sent as packets of information that are interpreted by the Arduino which controls the LEDs.
