*The graph above isolates individual audio frequencies within a waveform by using a Fast Fourier Transform algorithm. The algorithm returns an array of values based on 1.) amplitude across time (in dark grey), and 2.) amplitude across audible frequencies (in pink). The audio track comes from the NASA Voyager Missions (1977 -), where the space probes recorded magnetic waves emanating from planetary bodies. The magnetic waves were later mapped into the corresponding audio frequencies that we are hearing right now. To hear the full album click here.
