Abstract
Apparatus for providing an optical display as a function of frequency and amplitude of an audio music signal comprising a plurality of frequency selection circuits and a corresponding plurality of linear optical displays for providing a composite bar display comprising a plurality of linear bar segments each having a length which varies as a function of amplitude of a corresponding frequency component of the input music signal. The display is preferably in the form of a row and column array of individual optical display elements such as LED's. The apparatus also includes bar/dot display drivers and an operator-responsive switch for alternately selecting either a bar or a dot display at the LED array.
