Patent ID: 7369667

Claim:
An acoustic image localization signal processing device, comprising: a sound source data storage unit storing second sound source data obtained by signal processing of first sound source data such that an acoustic image of said first sound source data is localized in one of a reference direction and a reference position; localization information control means receiving movement information for moving the acoustic image of said first sound source data and providing one of an acoustic image localization direction and an acoustic image localization position of said first sound source data with respect to one of said reference direction and said reference position based on the movement information; and, acoustic image localization characteristic application means applying an acoustic image localization characteristic to said second sound source data read from said sound source data storage unit based on one of the acoustic image localization direction and acoustic image localization position provided by said localization information control means; wherein processing to apply an acoustic image localization characteristic to second sound source data by said acoustic image localization characteristic application means is processing, in which a pair of output signals are obtained by applying at least two characteristic differences including a time difference and either a level difference or a frequency characteristic difference to the second sound source data.
