Abstract: The present technology relates to an information processing device and a data structure in which reproduction accuracy of a perceived sound can be improved. The information processing device of the present technology includes a generation unit configured to generate a transfer characteristic file storing measurement data of transfer characteristics of a sound according to acoustic characteristics of a measurement space and condition information indicating a condition at a time of measuring the transfer characteristics.

Abstract: The present technique relates to an information processing device, an information processing method, and a program that allow a user to adjust a personalized transfer function. The information processing device according to the present technique comprises an adjustment unit that adjusts personalized transfer characteristics, which are transfer characteristics of sound in a measurement environment and are personalized to a user, in response to an operation performed by the user. The information processing device according to the present technique further comprises a presentation unit that presents, to the user, contents of reference information referred to at the time of adjusting the personalized transfer characteristics, along with the personalized transfer characteristics. The present technique can be applied to, for example, a system that mixes audio of content such as movies.

Abstract: The present technology relates to an information processing apparatus, an information processing method, and a program capable of reproducing a sound pressure of a playback sound in a measurement environment. An information processing apparatus according to one aspect of the present technology records sound pressure reproduction data used to reproduce sound pressure of a speaker as a sound pressure when outputting a playback sound obtained by playback processing using transfer characteristics of sound in a measurement environment where the speaker is installed from an output apparatus prepared in a playback environment together with transfer characteristic data representing the transfer characteristics. The present technology can be applied to a system that performs audio mixing of contents such as movies.

Abstract: An information processing device according to an aspect of the present technology includes a storage unit that stores HRTF data corresponding to a plurality of positions based on a listening position, and a sound image localization processing unit that performs a sound image localization process based on the HRTF data corresponding to a position, in a virtual space, of a participant participating in a conversation via a network and sound data of the participant. The present technology can be applied to a computer that performs remote conference.

Abstract: The present feature relates to an information processing device, an output control method, and a program that allow a sense of distance about a sound source to be appropriately reproduced. An information processing device according to the present feature causes a speaker provided in a listening space to output sound of a prescribed sound source which constitutes the audio of a content and an output device for each listener to output sound of a virtual sound source different from the prescribed sound source, wherein the sound of the virtual sound source is generated by processing using a transfer function corresponding to a sound source position. The present disclosure is applicable to an acoustic processing system in a movie theater.

Abstract: Sound is flexibly reproduced. A sound processing device (10) according to an embodiment includes: an acquisition part (111) that acquires parameters relating to a way of sounding of sound from first sound data obtained by actual measurement; an adjustment part (1121) that adjusts the parameters in accordance with a space for reproduction; a synthesis part (1122) that generates third sound data from second sound data on the basis of parameters having been adjusted by the adjustment part (1121); and an output part (113) that reproduces the third sound data.

Abstract: The present technology relates to a signal processing apparatus and method that are capable of reproducing sound at an optional listening position with a high sense of reality. The signal processing apparatus includes a rendering unit that generates reproduction data of sound at an optional listening position in a target space on the basis of recording signals of microphones attached to a plurality of moving bodies in the target space. The present technology can be applied to a reproduction apparatus.
