Our senses of sound and of light are two of the most prominent senses that we use to understand the world. Both of these senses share the common dimension of time. In this project we will explore time and space through the transformation of sound into light. This is a device to visualize an audio signal. Just as music is perceived through the cochlea in our inner ears and processed in several parts of our brain, principally in the auditory cortex, we will follow a similar process of detection and analysis through the microcontroller.
In this prototype, we use different lengths of acrylid rods to map the different frequecies of audio signal. Below are the video presentation and poster.
