  • Patent number: 8269646
    Abstract: Disclosed is a light display comprised of a light display unit containing 24 LEDs of various colors, a USB connector connecting the light display unit to a computer, and light display custom software that is loaded onto the computer. When the computer plays music audio such as a WAV file, MP3 file, or a CD disk, the light display custom software, installed on the computer, transforms the audio output into a four 8-bit byte record 40 times a second. The first byte is a header record, and the remaining 3 bytes contain 24 instruction bits. The instruction bits are calculated using a programmed spectrum analyzer that filter the sampled audio signal over a range of 20 Hz to 20K Hz. When the frequencies within a given band exceeds a threshold, the bit associated with that band is set to 1, otherwise the bit is set to 0. The light display unit contains a circuit board that turns the LED associated with the bit on if the bit is one, otherwise it is turned off.
