发明名称 Sound field control device
摘要 In the sound field control device, main signals and a surround signal are generated on the basis of input left and right 2 channel signals, and 4 channel main sound field signals and 4 channel surround sound field signals which are respectively aggregations of reflected sound signals of various directions in the respective sound fields are generated on the basis of reflected sound parameters of sound fields established with respect to the main signals and the surround signal, and the 4 channel main sound field signals and the 4 channel surround sound field signals of each corresponding channel are combined together and provided as 4 channel sound field signals to be sounded. Reflected sounds are created on the basis of reflected sound parameters of a certain established sound field regardless of sound field components contained in a source signal and output as a sound field signal. By sounding the sound field signals by sound field control loudspeakers arranged about a listener, an effect that gives to the listener the impression that he is surrounded by the sound can be produced.
