초록 ▼

An acoustic image localization apparatus localizes an acoustic image of a plurality of tone color species having various timbres to a source point with respect to a listening point within a sound field. Desired ones of separate source points are specified, which are provisionally set throughout the sound field. Each of the tone color species is assigned to one or more of the specified source points such that each specified source point is assigned with a group of desired tone color species. Acoustic images of the respective groups are localized to corresponding ones of the specified source points. Further, one of separate listening points is designated, which is provisionally set relatively to the source points so that the acoustic images are localized with respect to the designated listening point.

대표청구항 ▼

[ What is claimed is:] [1.] An acoustic image localization apparatus comprising:a generator that generates a sound signal;a memory device that stores a plurality of impulse response data;a first designator circuit that designates one of separate listening points that are predetermined separately from each other in a sound field;a second designator circuit that designates one of separate source points that are predetermined separately from each other in a sound field; anda sound localizer that localizes an acoustic image of the sound signal to a sound point by filtering the sound signal based on impulse response data read out from the memory in accordance with the listening point designated by the first designator circuit and the source point designated by the second designator circuit, wherein the acoustic image of the sound signal is localized to the designated source point as if the acoustic image is directed to the designated listening point.
