ABSTRACT:
A sound processing system increases the robustness of surround sound in various playback situations. The system may process an incoming signal, such as a five channel surround sound signal, with a first and a second matrix. The first and second matrices produce outputs signals from the input incoming signals. At least one of the output signals may be combined before being sent to the speakers.
