PROBLEM TO BE SOLVED: To provide an apparatus for creating, utilizing a pair of oppositely opposed headphone speakers, the sensation of a sound source being spatially distant from the area between the pair of headphones. SOLUTION: The present invention relates to an apparatus for creating, utilizing a pair of oppositely opposed headphone speakers, the sensation of a sound source being spatially distant from the area between the pair of headphones, the apparatus comprising: (a) a series of audio inputs representing audio signals being projected from an idealized sound source located at a spatial location relative to the idealized listener; (b) a first mixing matrix intermediate output means interconnected to the audio inputs and a series of feedback inputs; (c) a filter system including separate filters for filtering the direct response and short time response and an approximation to the reverberant response, in addition to the feedback response filtering for producing the feedback inputs; and (d) a second matrix mixing means combining the filtered intermediate output signals.
