<p>An audio signal processing apparatus includes: €¢ a dividing section (11L, 11R) dividing each of audio signals of a plurality of channels (Lch, Rch) into a plurality of frequency bands (sub1-L, ..., subn-L, sub1-R, ..., subn-R);
€¢ a phase difference calculator (22) calculating a phase difference (¸ lr ) between the audio signals of the plurality of channels, for each of the plurality of frequency bands;
€¢ a level ratio calculator (23) calculating a level ratio (mag lr ) between the audio signals of the plurality of channels, for each of the plurality of frequency bands;
€¢ a localization angle input (10) for designating a localization angle; and
€¢ an audio signal processor performing output gain setting (13-1, ..., 13-n, 24) with respect to divided signals obtained by the dividing section, on the basis of the phase difference and the level ratio for each of the plurality of frequency bands, and on the basis of the designated localization angle.</p> |
