A spatial audio processing uses a matrix of channels and conditioning amplifiers. Four channels are created from two by using a left, right, mono and a differential amp. A timing gate is added and set to the bass frequency to switch the matrix. The matrix starts with channel one receiving the left program. On the next timing cycle, channel two receives the left program, while channel one receives the left rear program. Thereafter, channel three receives the right program and channel four receives the right rear program. This condition continues through the timing order until every channel has received all four programs and then repeats itself. The constant shift in program content eliminates standing waves in any area and opens up the sound in an area that becomes spatial or orbital.
