Abstract
In a wind noise reduction device that reduces wind noise contained in an input sound signal to generate a corrected sound signal, when a predetermined band including the band of the wind noise is a first band and a predetermined band higher in frequency than the first band is a second band, the wind noise reduction device includes: a first corrector that has a signal generator generating, based on a sound signal (i) contained in the input sound signal and lying in a band higher in frequency than the first band, a sound signal (ii) lying in the first band and different from a sound signal (iii) contained in the input sound signal and lying in the first band, and that generates a first corrected sound signal based on the sound signal (ii) generated by the signal generator; a second corrector that reduces the signal level of a sound signal (iv) contained in the input sound signal and lying in the second band to thereby generate a second corrected sound signal as a sound signal (v) having the wind noise reduced and lying in the second band; and a corrected sound signal outputter that outputs the corrected sound signal based on the first and second corrected sound signals.
