PROBLEM TO BE SOLVED: To provide a noise removal device, noise removal method, and noise removal program capable of effectively reducing wind noise.SOLUTION: A noise removal device includes: a subtractor 73 for calculating a difference signal between a sound signal of one channel and a sound signal of the other channel among multiple sound signals input from multiple sound channels; an adaptive filter 10 for defining the sum signal of a difference signal and an internal generation signal as an input and defining a signal correlated to the internal generation signal as a desired signal input; and a variable filter 61 that changes characteristics with the characteristic change of a variable filter inside the adaptive filter and processes a sound signal. |
