Abstract
An acoustic reproduction method includes: localizing a first sound image at a first position in a target space in which a user is present; and localizing, at a second position in the target space, a second sound image that represents an anchor sound for indicating a reference position.
Claims15
An acoustic reproduction method comprising:
- obtaining a sound signal indicating a first sound image and positional information pertaining to a first position indicating a position of the first sound image;
- localizing, based on the positional information, the first sound image at the first position in a target space in which a user is present;
- and
- localizing a second sound image at a second position in the target space, the second sound image representing an anchor sound for indicating a reference position,
- the second position being determined according to a frontal direction in which a face of the user faces or a horizontal direction corresponding to a position of the user as a reference.

An acoustic reproduction device comprising:
- a decoder that decodes an encoded sound signal to obtain a sound signal indicating a first sound image and positional information pertaining to a first position indicating a position of the first sound image, the sound signal causing a user to perceive a first sound image;
- a first localizer that localizes, based on the positional information according to the encoded sound signal that has been decoded, the first sound image at the first position in a target space in which the user is present;
- and
- a second localizer that localizes a second sound image at a second position in the target space, the second sound image representing an anchor sound for indicating a reference position,
- the second position being determined according to a frontal direction in which a face of the user faces or a horizontal direction corresponding to a position of the user as a reference.
