Abstract: According to the present disclosure, a sound output device includes: a sound acquisition part configured to acquire sound to be output to the other end of a sound guide part, one end of which is arranged near an entrance of an ear canal of a listener, the sound guide part having a hollow structure; and a head-related transfer function adjustment part configured to adjust a head-related transfer function of sound captured by the sound guide part. Since the head-related transfer function adjustment part adjusts the head-related transfer function of sound captured by the sound guide part, it is possible to listen to both ambient sound and sound provided from a sound output device such that the listener does not feel strangeness even in the state in which the listener is wearing the sound output device.

Abstract: The present technology relates to an HRTF measurement method, an HRTF measurement device, and a program which can more simply acquire a head-related transfer function of an individual.The HRTF measurement device displays an image indicating a target direction that a user is to face. In a case where a front direction of the user and the target direction are matched, the HRTF measurement device outputs a measurement sound from a speaker and measures an HRTF on the basis of a result of receiving the measurement sound through a microphone mounted on an ear of the user. The present technology can be applied to, for example, a device which measures a head-related transfer function and the like.

Abstract: The present disclosure relates to a signal processing device, a signal processing method, and a program that allows for generating an input signal suitable for a multi-way speaker. A band dividing unit divides an audio signal into signals in a plurality of bands corresponding to respective bands of a plurality of speaker units of the multi-way speaker. A filter processing unit performs wave front synthesis filter processing on each of the audio signals in the respective bands having been divided into. The audio signal in each of the bands after the wave front synthesis filter processing is supplied to the speaker unit of the corresponding band in the multi-way speaker. The present disclosure is applicable, for example, to a signal processing device or other devices.

Abstract: The present technology relates to a sound field reproduction apparatus and method, and a program, enabled to more accurately reproduce a sound field. A spacial filter application unit obtains a virtual speaker array drive signal of an annular virtual speaker array with a radius larger than a radius of a spherical microphone array, by applying a spacial filter to a spacial frequency spectrum of a sound collection signal obtained by having the spherical microphone array collect sounds. An inverse filter generation unit obtains an inverse filter based on a transfer function from a real speaker array up to the virtual speaker array. An inverse filter application unit applies the inverse filter to a time frequency spectrum of the virtual speaker array drive signal, and obtains a real speaker array drive signal of the real speaker array. The present technology can be applied to a sound field reproduction device.

Abstract: To record and reproduce sound and an image so that content which entertains a viewer and which prevents the viewer from being bored is provided while realistic sensation is provided.Upon recording, image information shot by a plurality of cameras is recorded together with position and posture information of each camera, and acoustic information from a plurality of sound sources is recorded together with position information of each sound source. Upon reproduction, an image at a position of a viewer (eye direction) is reproduced, and a sound image is localized at the position of the viewer so that content which entertains the viewer and which prevents the viewer from being bored is provided while sound with realistic sensation is provided.
