ABSTRACT:
A device (10) for producing light enhanced sound from a music source (36) producing music signals on at least a first (54) and second (56) channel is provided. The device (10) includes a speaker (18 or 20) for reproducing music from the music signals. The device (10) also includes axis-crossing detection circuitry (69) coupled to the first (54) and second (56) channels that detects when the music signal on each channel crosses the time-axis and generates an axis-crossing signal. The present device (10) further includes light control circuitry (81) coupled to the axis-detecting circuitry (69) operable to generate a light signal responsive to the axis crossing signals. The present device (10) also includes a light (42) coupled to the light control circuitry (81). The light (42) is illuminated responsive to the light signal.
