Vocal Signs

This was a quick evening project to get some initial understanding of data visualization.

We recorded our friends all speaking the same phrase, “Welcome to Copenhagen” in this case and visualized these recordings in the form of colorful signatures overlaid on each other. A basic level of control was added to select/deselect certain voices.

The project allowed us to understand some concepts like labeling and  presentation leading to successful correlation in any data visualization scheme. Apart from that it was also a hands on experience with setting up and feeling the nuances of Processing for a longer weeklong project.

The project uses the Minim library in processing to calculate the amplitude (or simply, the volume) at each instant of a voice recording. This data is then plotted on the screen.
