PROBLEM TO BE SOLVED: To provide a sound recording device that maintains pre noise-reduced localized perception of a sound or sense of presence thereof even after the noise is reduced.SOLUTION: Sound recording devices 1 and 10 according to the present invention comprise: a plurality of sound collecting parts 41; a first noise estimation part 52L that performs a first noise estimation of a first sound collected by a first sound collecting part 41L of sound collecting parts 41; a first noise reduction part 53L that reduces the noise estimated by the first noise estimation part 52L from the first sound; and a second adjustment part 54R that calculates a first relation R serving as a relation between a second sound collected by a second sound collecting part 41R of the plurality of sound collecting parts 41 and the pre noise-reduced first sound, and adjusts the second sound so as to make a relation between the second sound and the post noise-reduced first sound equal to the first relation R. |
