摘要： The present technology relates to audio processing. An acquisition unit acquires metadata including position information indicative of a position of an audio object and sound image information configured from a vector of three dimensions and representative of an extent of a sound image from the position. A vector calculation unit
determines a three-dimensional vector representative of the position of the audio object, wherein a start point of the three-dimensional vector is the origin in a three-dimensional coordinate system whose origin is given by a position of a user. The vector calculation unit further calculates, based on the three-dimensional vector and a ratio between a horizontal direction angle and a vertical direction angle of a region representative of the extent of the sound image determined by the sound image information, at least one spread vector indicative of a position in the region, wherein the number of spread vectors is determined in advance. A gain calculation unit calculates, based on the at least one spread vector, a gain of each of audio signals supplied to two or more sound outputting units positioned in the proximity of the position indicated by the position information by using Vector Base Amplitude Panning.

摘要： The present technology relates to an audio processing device, a method therefor, and a program therefor capable of achieving more flexible audio reproduction.
An input unit receives input of an assumed listening position of sound of an object, which is a sound source, and outputs assumed listening position information indicating the assumed listening position. A position information correction unit corrects position information of each object on the basis of the assumed listening position information to obtain corrected position information. A gain/frequency characteristic correction unit performs gain correction and frequency characteristic correction on a waveform signal of an object on the basis of the position information and the corrected position information. A spatial acoustic characteristic addition unit further adds a spatial acoustic characteristic to the waveform signal resulting from the gain correction and the frequency characteristic correction on the basis of the position information of the object and the assumed listening position information. The present technology is applicable to an audio processing device.

摘要： Provided is a decoding device including a demultiplexing section configured to demultiplex a coded bit stream, and extract transform window information indicating a type of a transform window used in time-frequency transform of an audio signal and coded data regarding frequency spectrum information obtained by the time-frequency transform from the coded bit stream. The decoding device further includes a decoding section configured to decode the coded data. Additionally, the decoding device includes a decoding scheme selection section configured to select a decoding scheme for the decoding section based on the transform window information. The decoding scheme selection section is configured to control the decoding section to decode the coded data by a decoding scheme corresponding to Huffman coding in a case in which the type of the transform window indicated by the transform window information is a transform window selected at a time of changing over the transform window length from a small transform window length to a large transform window length. Furthermore, the decoding scheme selection section is configured to control the decoding section to decode the coded data by a decoding scheme corresponding to arithmetic coding in a case in which the type of the transform window indicated by the transform window information is not the transform window selected at the time of changing over the transform window length from the small transform window length to the large transform window length.
