    Abstract: The present technique relates to an information processing apparatus, an information processing method, and a program capable of performing appropriate remapping.An offset angle calculation section calculates an offset amount of a position of a reference screen from a reference position present in a front direction of a user, and a position information correction section corrects a position of an audio object referred with the reference position, in conformity with the position of the reference screen on the basis of the offset amount. Furthermore, an object remapping section remaps the position of the audio object in conformity with a position of a reproduction screen on the basis of the corrected position of the audio object. The present technique can be applied to an information processing apparatus.

    Abstract: The present technology relates to a coding device and method, and a decoding device and method, and a program capable of reducing the amount of calculations for decoding.A separating unit separates a supplied bit stream into coded data of channel sources including a dialog source, coded data of additional data sources, and coded data of dialog information. A dialog information decoding unit decodes the coded data of the dialog information. When the dialog information acquired by the decoding is presented to a viewer, the viewer selects one source from the dialog source and some additional dialog sources. An additional dialog source decoding unit decodes only the coded data of an additional dialog source selected by the viewer. An additional dialog selection unit outputs a viewer-selected audio signal from among the audio signals of the dialog source and additional dialog sources in response to the selection instruction of the viewer. The present technology is applicable to coding devices and decoding devices.

    Abstract: The present technology relates to an encoding apparatus, an encoding method, a decoding apparatus, a decoding method, and a program for obtaining sound of higher quality.An audio signal decoding section decodes encoded audio data to acquire an audio signal of each object. A metadata decoding section decodes encoded metadata to acquire a plurality of metadata about each object in each frame of the audio signal. A gain calculating section calculates VBAP gains of each object in the audio signal for each speaker based on the metadata. An audio signal generating section generates an audio signal to be fed to each speaker by having the audio signal of each object multiplied by the corresponding VBAP gain and by adding up the multiplied audio signals. The present technology may be applied to decoding apparatuses.

    Abstract: The present technology relates to an encoding device, an encoding method, a reproduction device, a reproduction method, and a program enabling each reproduction equipment to reproduce an appropriate content in a simplified manner. A content data decoding unit decodes encoded metadata and outputs zoom area information, which is included in metadata acquired as a result thereof, designating an area to be zoomed. A zoom area selecting unit selects one or a plurality of pieces of zoom area information from among the zoom area information. A video segmenting unit segments a zoom area represented by the selected zoom area information in a video based on video data and outputs zoom video data acquired as a result thereof. An audio converting unit performs an audio converting process according to the selected zoom area information for audio data and outputs zoom audio data acquired as a result thereof. The present technology can be applied to a reproduction device.

    Abstract: The present technology relates to an audio processing apparatus and method and a program that make it possible to obtain sound of higher quality.An acquisition unit acquires an audio signal and metadata of an object. A vector calculation unit calculates, based on a horizontal direction angle and a vertical direction angle included in the metadata of the object and indicative of an extent of a sound image, a spread vector indicative of a position in a region indicative of the extent of the sound image. A gain calculation unit calculates, based on the spread vector, a VBAP gain of the audio signal in regard to each speaker by VBAP. The present technology can be applied to an audio processing apparatus.

    Abstract: An audio signal processing apparatus that includes a band division section, an analysis section, a gain adjustment amount calculation section, and a gain adjustment section. The band division section is configured to generate a resonance in-band signal by band division on an audio input signal. The analysis section is configured to extract an amount of features from each of the resonance in-band signal and the input signal. The gain adjustment amount calculation section is configured to calculate a gain adjustment amount for a resonance frequency band in the input signal, the gain adjustment amount being calculated based on the amount of features of the resonance in-band signal and the amount of features of the input signal. The gain adjustment section is configured to perform a gain adjustment on the resonance frequency band in the input signal based on the gain adjustment amount.
