    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.
