  • Monaural to stereo sound translation process and apparatus
    Patent number: 5394472
    Abstract: A process and apparatus are disclosed which provides increased perceptual location control and spatial characteristics to existing multi-channel material, said apparatus includes a plurality of input terminals adapted for receiving multi-channel audio input; at least one processing channel having gain control means, at least one processing channel having time delay means, which in combination, spatially enriches previously existing multi-channel material. The process for providing increased spatial characteristics to existing multi-channel material teaches operations in accordance with the apparatus.

  • Monaural to stereophonic sound translation process and apparatus
    Patent number: 5056149
    Abstract: A circuit for generating a multi-channel audio output from a single channel input. In the circuit, the single channel input may include gain control. The circuit divides the single channel input into at least two signals, each of which may have applied to it gain control, time delay, tone control and/or phase inversion. The gain controlled, time delayed, phase inverted and/or tone controlled signals are each input to an amplifier to create the multi-channel audio output.
