Apparatus for translating audio signals and producing a visual color display that portrays music. Circuits responsive to audio signal amplitude cause the display brightness to vary in accordance with the loudness of the music source. Circuits responsive to audio signal frequency content cause the color of the display to vary in accordance with the frequency spectrum of the music source. The audio frequency spectrum is evaluated by circuits which divide the spectrum into multiple contiguous frequency bands without the use of traditional filtering techniques. A palette of preselected light colors is assigned to the frequency bands such that each band is displayed as a unique color. The display apparatus is comprised of multiple colored light sources enclosed within a curved translucent light diffusion globe. Light sources are activated singly or in combinations of two adjacent light sources to produce the most attractive color blending to appear on the surface of the globe.
