ABSTRACT:
An acoustic image localization signal processing device capable of localizing an acoustic image in an arbitrary direction includes: a sound source data storage unit that stores second sound source data obtained by subjecting first sound source data to signal preprocessing in advance, such that the acoustic image is localized in a predetermined direction; and an acoustic image localization characteristic application processing unit that applies an acoustic image localization position characteristic, based on position information from an acoustic image control input unit, to the second sound source data, when the second sound source data are read from the sound source data storage unit and reproduced by headphones. Accordingly, the acoustic image localization position of the reproduced output signals resulting from the second sound source data is controlled.
