摘要:
An audio reproduction apparatus includes: a delay equalizer (301), a delay equalizer (303), a level adjuster (314), and a level adjuster (317). The delay equalizer (301) equalizes an FL signal using an equalizer characteristic EQ9 that converts a characteristic of an audio signal perceived as being reproduced at a position of an FL speaker (104) with respect to a viewing position to be perceived as being reproduced at a position of a virtual speaker (201) with respect to the viewing position. The delay equalizer (303) equalizes the FL signal using an equalizer characteristic (EQ12) that converts a characteristic of an audio signal perceived as being reproduced at a position of an SL speaker (106) with respect to a viewing position to be perceived as being reproduced at a position of the virtual speaker (201) with respect to the viewing position. The level adjuster (314) performs level adjustment, using a first coefficient K9, on an output signal of the delay equalizer (301). The level adjuster (317) performs level adjustment, using a second coefficient K12, on an output signal of the delay equalizer (303).
