Abstract:
An audio signal reproduction device generates, from an obtained audio signal, first reproduction signals for the first speaker group, sounds from which are localized at first virtual sound positions, and second reproduction signals for the second speaker group, sounds from which are localized at second virtual sound positions substantially the same as the first virtual sound positions. The audio signal reproduction device generates the first reproduction signals and the second reproduction signals so that at least phases or sound pressure values of a first sound and a second sound are different at a listening position, the first sound being indicated by the first reproduction signals, and localized at a first position among the first virtual sound positions, the second sound being indicated by the second reproduction signals, localized at a substantially same position as the first position, and substantially the same as the first sound.
