Document Type and Number:
WIPO Patent Application WO/2016/208406
Kind Code:
A1
Abstract:
The present technology pertains to a device, a method, and a program for processing sound which are capable of acquiring sound having higher quality. This acquisition unit acquires an audio signal and meta data of an object. This vector calculation unit calculates a spread vector indicating a position within a region indicating spread of a sound image, on the basis of the angle in the horizontal direction and the angle in the vertical direction which indicate spread of the sound image, and which are included in the meta data of the object. This gain calculation unit calculates a VBAP gain of the audio signal for each speaker by VBAP on the basis of the spread vector. This feature can be applied to a sound processing device.
