ABSTRACT:
An interface unit for providing visual color display of objects on an unaltered TV receiver which are directly associated with the music on an audio source. Audio energy is derived from separate channels of a stereo system. This audio information is presented on the screen in the form of objects in various arrangements. Color is derived based on the zero crossing rate of each channel. Each channel has its own color associated with it. Objects may be solid, or rings, or one may be "subtracted" one from the other. If desired, the different arrays may be selected automatically in a random manner. A spectral color modulator using phase shifted techniques is incorporated.
