Matrixing encoded multichannel audio onto two-channel media at the cost of channel separation
Evidence
All these signals can be encoded into and derived from a two-channel format using a technique called matrixing. However, this results in a considerable loss of separation between channels, but it was the only way to achieve it when only two channel distribution formats such as vinyl discs or stereo film tracks were available. Better performance is obtained from a multichannel formant, and with the advent of digital distribution formats that can provide discrete channels, this has become the norm, although some systems also use the matrixing technique to derive additional speaker feeds for more complex reproduction layouts. — David M.
