    Sound into Graphics



    Sound was used to generate computer graphics images. Music of interest was digitized at 40 KHz and the discrete samples converted to characteristic frequency values via DFFT for each 1/24-th of a second of “action”. The DFFT values were mapped onto an 8 x 12 grid, polygons constructed, and then rendered via scan conversion.
