Instead of seeking to reproduce the physical details of the original sound field, the potentially simpler approach of reproducing its psychoacoustic attributes is taken as a primary goal. Multichannel stereo is seen as offering the possibilities of a wider range of localization and the full perception of ambiance, to further enhance high-fidelity reproduction. These possibilities, already demonstrated in Triphonic-System reproduction from two-channel recordings, are developed further in the Dual-Triphonic system to provide stable, predictable, four-quadrant localization with full ambiance. This is a matrix system that avoids the principal phasing faults of other such systems, while exploiting established psychoacoustic principles for maximum effectiveness. Since it uses only two channels of information, it is fully compatible with normal stereo practice, and it makes no further demands for information capacity, whether in broadcasting or in recording.
