Sony patents system to place virtual sounds in real rooms
Sony describes a device that tracks the location of a sound source in one area and a listener in another. It calculates a specific spot in the room where the sound should appear and uses a speaker array to create that effect.
In the filing’s own words
An information processing device according to the present technology includes: a position information acquisition unit that acquires position information of a first target object in a first space in which a speaker array is arranged and position information of a second target object in a second space; a position determination processing unit that determines a virtual position of the second target object in a first fusion space obtained by virtually fusing the second space to the first space; and an output control unit that performs output control of the speaker array by applying a wavefront synthesis filter to a signal obtained by collecting a sound emitted from the second target object such that a sound image is localized at the virtual position.
What exactly they claim (claim 1)
1. An information processing device comprising: a position information acquisition unit that acquires position information of a first target object in a first space in which a speaker array is arranged and position information of a second target object in a second space; a position determination processing unit that determines a virtual position of the second target object in a first fusion space obtained by virtually fusing the second space to the first space; and an output control unit that performs output control of the speaker array by applying a wavefront synthesis filter to a signal obtained by collecting a sound emitted from the second target object such that a sound image is localized at the virtual position.
