AB  - Azimuthal harmonic synthesis generates a universe of matrices (UMX) with maximal input-output azimuthal correlations for two (BMP), three (TMX), four (QMX), etc., intermediary channels. The basic mono-stereo-compatible BMX accepts augmentation channels converting to TMX, QMX, etc., In quadrasonics, the psychoacoustically discrete TMX essentially equals the fully discrete QMX. The feasibility of multichannel disc, broadcast, and tape is profoundly enhanced by the sufficiency of using 2-kHz-wide augmentation channels.
