Abstract
Various techniques for synchronizing illumination with an audio signal are disclosed. According to one aspect of the techniques, an audio signal continuously is received and processed one phase or period at a time in an analyzing or detecting unit. From one phase of the audio signal, a set of light controlling parameters are determined from a look-up-table. These light controlling parameters are used to adjust duty cycles of square waves used to drive a plurality of light sources such that the illumination produced is in accordance with the audio signal.
Claims18
