Abstract:
According to one embodiment, audio controlling apparatus includes first receiver configured to receive audio signal, second receiver configured to receive environmental sound, masking gain calculator configured to calculate masking gain for each frequency band, based on audio signal and environmental sound, and gain controller configured to smooth masking gain of frequency band that is less than preset threshold frequency in first interval, smooth masking gain of frequency band that is equal to or higher than threshold frequency in second interval that is longer than first interval, and thereby set gain.
