Abstract
In frequency signals obtained by converting input audio signals from time-domain signals to frequency-domain signals, a level control value setting unitestablishes a level control value for reducing the levels of spectrums at a noise-components level. A level control value smoothing unitcarries out a smoothing process of smoothing the level control value established by the level control value setting unittemporally. A spectral adjustment unitmultiplies the level control value after the smoothing process by the frequency signals, performing a level control.
