Abstract
A method and apparatus for storing and presenting visual and audible information to an individual. Audio source signals from a stereophonic audio source are processed by a microcontroller-controlled circuit that also receives commands from a programmer. The programmer commands cause the generation of pulsed low audio frequency control signals for each channel. The audio source signals are processed so that their frequencies are translated above the low audio frequency range of the pulsed control signals and inverted. The pulsed control signals are then added to the corresponding processed audio source signals to produce two combined audio signals which are then recorded on a compact disc. To replay the recorded information, the recorded combined audio signals are read from the compact disc. The pulsed control signals and processed audio source signals are separated by filtering and the processed audio source signals are reprocessed to recreate the original audio source signals. The pulsed control signals drive separate channel LED displays built into a headset visor and the audio source signals are concurrently played through speakers in the headset. Also disclosed is a method for using the apparatus so that the individual can learn information.
