Abstract
An audio signal processing apparatus includes a localization direction detector that detects localization directions of two-channel input audio signals, a localization direction distribution calculator that calculates a distribution of the localization directions detected by the localization direction detector, a gain table information recording unit that records gain table information defining weights corresponding to respective localization angles, a gain generator that generates a gain corresponding to an output audio signal on the basis of the distribution calculated by the localization direction distribution calculator and the gain table information recorded in the gain table information recording unit, and a synthesizing unit that synthesizes the two-channel input audio signals using the gain generated by the gain generator.
