Abstract
An audio reproduction apparatus includes: a delay equalizer (), a delay equalizer (), a level adjuster (), and a level adjuster (). The delay equalizer () equalizes an FL signal using an equalizer characteristic EQthat converts a characteristic of an audio signal perceived as being reproduced at a position of an FL speaker () with respect to a viewing position to be perceived as being reproduced at a position of a virtual speaker () with respect to the viewing position. The delay equalizer () equalizes the FL signal using an equalizer characteristic (EQ) that converts a characteristic of an audio signal perceived as being reproduced at a position of an SL speaker () with respect to a viewing position to be perceived as being reproduced at a position of the virtual speaker () with respect to the viewing position. The level adjuster () performs level adjustment, using a first coefficient K, on an output signal of the delay equalizer (). The level adjuster () performs level adjustment, using a second coefficient K, on an output signal of the delay equalizer ().
