  • Method and apparatus for generating audiospatial effects
    Patent number: 5487113
    Abstract: A method and apparatus is disclosed for producing one or more audiospatial effects in an original audio signal. A spatially disorienting signal, typically a modified white noise pattern, is combined with the original audio signal. A spatially reorienting signal is further combined with the original audio signal in order to give a listener the perception, upon hearing the original audio signal played back, that the sound emanates from a predetermined direction.
