Abstract: The system of the present invention includes, briefly, a point source speaker system, comprising a processor which produces a left minus right (L−R) audio signal, a right plus left (R+L) and a right minus left (R−L) audio signal; three speakers each for audibly transmitting one of the L−R, R+L and R−L audio signals; and a point source speaker enclosure for housing the three speakers in a single enclosure.

Abstract: A method of processing left and right audio signals is disclosed which reproduces the illusion of a center channel while achieving a perception by the listener of a wider speaker separation. This method is partly obtained by altering the spectral response of the left and right speaker signals to obtain left and right sets of odd and even Fourier Transforms having certain characteristics. These processed signals are re-combined with the unaltered left and right signals to produce an expanded separation image that appears to extend beyond the physical location of the actual left and right loudspeakers, and to simultaneously centralize center channel signals to a point located between the loudspeakers.
