摘要
To perform volume control matching the actual auditory sensation level of a human so as to improve the control accuracy. As shown in FIG. 1 , an audio gain adjustment device 10 includes: an audio signal input section 12 that acquires an audio signal to be adjusted; a long-term gain reflection section 14 that reflects the adjustment of long-term gain in the acquired audio signal; a frequency division section 20 that divides the audio signal from the long-term gain reflection section 14 into three frequency bands; a short-term gain reflection section 30 that reflects the adjustment of short-term gain in each frequency band; a synthesis section 40 that synthesizes audio signals output from the short-term gain reflection section 30; and an audio signal output section 42 that outputs the synthesized audio signal.
