  • Patent number: 5703955
    Abstract: A multichannel sound reproduction method and apparatus are described for achieving a higher proportion in the overall room size for acoustic/visual use, which can be used for the listening-position-independent reproduction of spatial information in maintaining the given directional information of the individual sound signal sources. In the described method, each signal is split up and, after a summation, part of it with an increased delay, a modified level and a changed phase position is supplied to one of the unchanged signal portions, with the aggregate signals being distributed and supplied to the two surround reproduction channels and to other reproduction loudspeakers distributedly located in the room in conformity with directional allocation and in accordance with the relevant unchanged signal portions.
