摘要: 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.

摘要: 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.
