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: A method, system, and computer program product for processing an encoded audio signal is described. In one exemplary embodiment, the system receives an encoded low-frequency range signal and encoded energy information used to frequency shift the encoded low-frequency range signal. The low-frequency range signal is decoded and an energy depression of the decoded signal is smoothed. The smoothed low-frequency range signal is frequency shifted to generate a high-frequency range signal. The low-frequency range signal and high-frequency range signal are then combined and outputted.

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.
