Abstract: An information processing method includes: (i) determining whether a type of a predetermined sound and a type of an external sound match; (ii) determining whether the incoming direction of the predetermined sound and the incoming direction of the external sound overlap by comparing the incoming direction of the predetermined sound with the incoming direction of the external sound analyzed; and performing at least one of the following based on a result of (i) and a result of (ii): (a) adjusting at least one of a sound pressure of the predetermined sound or a sound pressure of the external sound; or (b) adjusting the incoming direction of the predetermined sound.

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.

Abstract: A three-dimensional audio processing method for use in reproducing three-dimensional audio using an augmented reality (AR) device includes: obtaining change information indicating change occurring in a space in which the AR device is located when content that includes a sound is being output in the AR device; selecting, based on the change information, one or more audio processes among a plurality of audio processes for rendering sound information indicating the sound; executing only the one or more audio processes selected among the plurality of audio processes; and rendering the sound information based on a first processing result of each of the one or more audio processes executed.

Abstract: An acoustic reproduction method is an acoustic reproduction method for causing a user to perceive a first sound as a sound arriving from a first position in a three-dimensional sound field and a second sound as a sound arriving from a second position different from the first position in the three-dimensional sound field. The acoustic reproduction method includes: obtaining a movement speed of a head of the user; and generating an output sound signal for causing the user to perceive sounds that arrive from predetermined positions in the three-dimensional sound field. In the generating, when the movement speed obtained is greater than a first threshold, the output sound signal for causing the user to perceive the first sound and the second sound as a sound arriving from a third position between the first position and the second position is generated.

Abstract: An information processing method includes: obtaining spatial information indicating a shape of a virtual space including an obstacle and a sound source object that emits a predetermined sound; obtaining position information indicating a position and an orientation of a user in the virtual space; and generating an acoustic virtual environment by determining, based on the position and the orientation of the user and a position of the obstacle in the virtual space, a position of a virtual reflection surface off which the predetermined sound is reflected in the virtual space.

Abstract: A sound pickup device includes microphone elements arranged three-dimensionally in a distributed manner. A total number of effective microphone pairs is greater than a total number of the microphone elements, the effective microphone pairs each being a combination of two microphone elements having a distance less than a distance D between each other. The distance D is represented by D=c/2f, where f represents a frequency of a target sound obtained from each of the microphone elements and c represents a velocity of the target sound. Any one of straight lines each of which connects the two microphone elements of a different one of the effective microphone pairs is not parallel to any other of the straight lines.
