Abstract
An audio reproduction apparatus is provided which is capable of maintaining the sense of dimensions in an acoustic space even when multi-channel input audio signals are reproduced using speakers having different frequency characteristics. The audio reproduction apparatus includes: a sound source position parameter calculating unit () that calculates a localization position of a sound image when reproduced by each of the first and second speaker groups; a reproduction signal generating unit () that generates a reproduction signal by separating, from audio signals corresponding to the second speaker group, audio signals representing a sound having a sound pressure level higher when reproduced by the first speaker group than the second speaker group; and a signal correction unit () that corrects reproduction signals such that the sound image localized according to the reproduction signals are localized at a substantially identical position to the calculated localization position; and a delay time adjusting unit ().
