AB  - A compatibility problem exists when two-channel program material is played over loudspeaker layouts with more than two front loudspeakers. Two-channel music recordings, when used either as cinema sound tracks or played on a typical home theater setup, are examples, as are older quadraphonic and related recordings played over a 5.1 layout. The theory of generalized head-related stereophony of Cooper and Bauck applies to this problem, indicating an infinite number of solutions. A few solutions are examined in detail, resulting in several remedial network specifications. These solutions are incorporated into a simulation and a signal-based error function, essentially a plot of the sweet spot is plotted for each and compared to errors which arise from conventional methods. Under several types of input signals, the new processor exhibits substantially better performance than conventional methods, yet it is simple and economical to implement.:
