Claims
- 1. In a UMX encoder comprising means for encoding multidirectional source signals in a plurality of at least two transmission channels with predetermined amplitude and phase relations indicative of source directions and two of said transmission channels being stereo compatible channels adapted to be decoded for formation of at least three loudspeaker presentation signals having source signals corresponding to every source direction appearing in a plurality of the presentation signals, the improvement comprising means for providing a left stereo compatible transmission channel T.sub.SL and means for providing a right stereo compatible transmission channel T.sub.SR, said T.sub.SL, T.sub.SR channels having encoding axes with an included angle in the range of from about 45.degree. to about 90.degree. wherein a source signal to be encoded from the encoding axis of one of said channels T.sub.SL, T.sub.SR is substantially null in the other of said channels.
- 2. An encoder in accordance with claim 1 wherein said stereo compatible signals are substantially defined by: ##EQU35##
