摘要:
PURPOSE: A wind noise suppressor, a semiconductor integrated circuit, and method for suppressing wind noise are provided to obtain an audio signal having a natural and good quality using a wind noise suppression part. CONSTITUTION: A division part(2) divides a first frequency band which can include wind noise in an input sound and a second frequency band having higher frequency than that of the first frequency band. A calculation part(3) calculates wind noise probability of the input sound from a characteristic parameter of the input sound of the first frequency band. A suppression part(4) suppresses the wind noise included in the input sound of the first frequency band with intensity of the calculated probability. An adding part(5) synchronizes the divided input sound of the second frequency band with the input sound of the first frequency band which suppresses the wind noise in the suppression part.
