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.

An acoustic processing apparatus () according to the present disclosure includes an acquisition unit (), a storage unit (), and a processing unit (). The acquisition unit () acquires location information regarding a location viewed by a user who listens to an acoustic content. The storage unit () stores acoustic information () regarding acoustics at the location. The processing unit () converts an acoustic characteristic of the acoustic content into an acoustic characteristic in accordance with the location on the basis of the acoustic information () and regenerates a sound field.

Acoustic processing apparatus, acoustic processing method, and acoustic processing program

The present disclosure relates to a signal processing device, a signal processing method, and a program that make it possible to readily achieve personalization of head-related transfer functions in all bands. A synthesis unit generates a third head-related transfer function by synthesizing a characteristic of a first band extracted from a first head-related transfer function of a user and a characteristic of a second band other than the first band extracted from a second head-related transfer function measured in a second measurement environment different from a first measurement environment in which the first head-related transfer function is measured. The present disclosure may be applied to, for example, a mobile terminal such as a smartphone.

Acoustic processing apparatus, acoustic processing method, and program

The present invention is directed to reducing influence of crosstalk components by appropriately blocking a propagation path of the crosstalk components output from speakers that reproduce signals for right and left ears respectively. Provided is a contact member used in contact with a back and/or a back of a head of a listener. The contact member is installed with: a first speaker that reproduces a signal for the left ear and a second speaker that reproduces a signal for the right ear; and a propagation obstruction adapted to block a propagation path of crosstalk components output from the respective speakers.

Acoustic device

To favorably reduce crosstalk components output from respective speakers that reproduce left and right ear signals. Directivity is given to a left ear signal and a right ear signal and the left ear signal and the right ear signal are reproduced by using at least two respective speakers arranged back-to-back to reduce crosstalk components. For example, the speaker may be a speaker installed in a headrest or a seat provided with the headrest. For example, the directivity given to the left ear signal and the directivity given to the right ear signal may be bidirectional directivity or unidirectional directivity.

To provide a sound pickup device which is worn on an ear of a user and used. A sound pickup device includes: a sound pickup part; and a holding part that includes a sound transmission part and is configured to hold the sound pickup part in an ear canal of a user. The holding part includes a ring body having an opening portion that serves as the sound transmission part, and one or more arms each of which has one end coupled to the ring body and another end supporting the sound pickup part. The ring body is inserted into a cavum concha of the user and is locked in a vicinity of an intertragic notch. The holding part holds the sound pickup part so that a microphone hole is oriented to outside of the ear canal and the microphone hole is positioned on a farther side of an entrance of the ear canal.
