<p>A speaker array having improvement in localization during reproduction of a front channel of surround sound, improvement in sense of density, improvement in narrow directivity during reproduction of stereo sound, and improvement in selectivity of reproduction practices in accordance with installation environment. When a speaker array for making surround sound into beams for reproduction is used to reproduce stereo sound, the speaker array is divided at the center thereof into an L-system channel sound reproduction area and an R-system channel sound reproduction area. Each of the thus divided reproduction areas is further divided for each of bands. The reproduction areas of a higher frequency band, when reproduced by use of a plurality of speakers at the same time, exhibit a high directivity and an enhanced sense of localization as previously described, and hence are limited to a certain area. Additionally, when the front system of a surround source is stereo reproduced, the center localization is improved by changing C processings of the L-system and R-system. In this way, natural stereo sense sound can be reproduced without making the higher frequency band of sound into beam.</p> |
