An audio signal processing device includes a gain control portion ( 11, 12 ) that controls a gain of an input audio signal (S 1 ), a noise suppression quantity calculating portion ( 13 ) that calculates noise suppression quantity (SL) with respect to the audio signal, a correcting portion ( 14 ) that corrects the noise suppression quantity (SL) based on a gain (GL) calculated by the gain control portion, and a noise suppressing portion ( 15 ) that suppresses a noise component included in the audio signal based on a corrected noise suppression quantity (SLH).
