PURPOSE:To reproduce a real sound field by collecting a sound by a first sound collecting means in which non-directional microphones are arranged in three dimensions and a second sound collecting means in which directional microphones to form a pair with the first sound collecting means are arranged centralizingly, and mixing the sound, and reproducing it by the speakers of the same number as the number of the non-directional microphones. CONSTITUTION:The first sound collecting means constituted by arranging plural non-directional microphones 16 to 23 on a virtual sound collecting system three-dimensional solid 10 and the second sound collecting means constituted by arranging the directional microphones 26 to 33 of the same number as the number of the first sound collecting means as directing their directivities toward the non-directional microphones to form a pair with them respectively in the inner position of the virtual sound collecting system three-dimensional solid 10 the first sound collecting means forms are arranged. Then, the sound is collected by the first and the second sound collecting means, and these collected sound are mixed, and the mixed sound is reproduced from the each speaker 46 to 53 of a reproducing means. At that time, in the reproducing means, the speakers 46 to 53 of the same number as the number of the non-directional microphones 16 to 23 are arranged so that their positions correspond to each respectively. Thus, spatiality can be obtained by the first sound collecting means, and directivity can be obtained by the second sound collecting means, and the real sound field can be reproduced. |
