An information processing apparatus, a control method, and a control program capable of providing an experience close to one experienced in a real space to a user are provided. An information processing apparatus includes: an acquisition unit configured to acquire terminal position information of a communication terminal; a holding unit configured to hold a predetermined area and acoustic-image localization position information of an audio content to be output to the communication terminal while associating them with each other; a generation unit configured to generate acoustic-image localization information based on the acoustic-image localization position information and the terminal position information when the terminal position information is included in the predetermined area; and an output unit configured to output the acoustic-image localization information.

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.

Some implementations may involve receiving, via an interface system, personnel location data indicating a location of at least one person and receiving, from an orientation system, headset orientation data corresponding with the orientation of a headset. First environmental element location data, indicating a location of at least a first environmental element, may be determined. Based at least in part on the headset orientation data, the personnel location data and the first environmental element location data, headset coordinate locations of at least one person and at least the first environmental element in a headset coordinate system corresponding with the orientation of the headset may be determined. An apparatus may be caused to provide spatialization indications of the headset coordinate locations. Providing the spatialization indications may involve controlling a speaker system to provide environmental element sonification corresponding with at least the first environmental element location data.

An apparatus including at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured, with the at least one processor, to cause the apparatus at least to: generate content lock information for a content lock, wherein the content lock information enables control of audio signal processing associated with audio signals related to one or more audio sources based on a position and/or orientation input.

Systems and methods of presenting an output audio signal to a listener located at a first location in a virtual environment are disclosed. According to embodiments of a method, an input audio signal is received. For each sound source of a plurality of sound sources in the virtual environment, a respective first intermediate audio signal corresponding to the input audio signal is determined, based on a location of the respective sound source in the virtual environment, and the respective first intermediate audio signal is associated with a first bus. For each of the sound sources of the plurality of sound sources in the virtual environment, a respective second intermediate audio signal is determined. The respective second intermediate audio signal corresponds to a reverberation of the input audio signal in the virtual environment. The respective second intermediate audio signal is determined based on a location of the respective sound source, and further based on an acoustic property of the virtual environment. The respective second intermediate audio signal is associated with a second bus. The output audio signal is presented to the listener via the first bus and the second bus.

A wearable electronic device (WED) corrects an error where a user hears binaural sound. A processor processes sound into binaural sound that localizes to the user at a location, and the WED determines a gaze direction of the user when the user hears the binaural sound. The WED corrects an error between the location and the gaze direction.

An illustrative audio processing system identifies an experience location with which an augmented reality presentation device is associated. The experience location is included within a multizone augmented reality space that is presented by the augmented reality presentation device. The audio processing system determines that the experience location is within both a first sound zone and a second sound zone of the multizone augmented reality space, and, based on the determining that the experience location is within both the first and second sound zones, generates a binaural audio stream for presentation by the augmented reality presentation device. The binaural audio stream includes an environmental audio component implemented by a mix of a first environmental audio stream associated with the first sound zone and a second environmental audio stream associated with the second sound zone. Corresponding methods and systems are also disclosed.

A system for obtaining content for display to a user of a head-mountable display device, HMD, the system comprising one or more audio detection units operable to capture audio in the environment of the user, a motion prediction unit operable to predict motion of the HMD in dependence upon the captured audio, and a content obtaining unit operable to obtain content for display in dependence upon the predicted motion of the HMD.

A method or apparatus switches between binaural sound and stereo sound in response to head movements of a listener. An electronic device provides the listener with binaural sound at a sound localization point (SLP) in a field-of-view of the listener. Binaural sound at the SLP switches to one of mono or stereo sound when head movements of the listener cause the SLP to move outside the field-of-view.

A hearing assistance device adapted to be worn by a wearer comprises a processor configured to generate a sequence of audio cues that audibly guide the wearer through a series of actions involving the wearer's head and neck in accordance with a predetermined corrective or therapeutic maneuver. A speaker is configured to play back the sequence of audio cues for reception by the wearer. One or more sensors are configured to sense movement of the head during each of the actions. The processor is configured to determine if head movement for an action associated with each audio cue has been correctly executed by the wearer, and produce an output indicative of successful or unsuccessful execution of the actions by the wearer.
