Title:
SPATIAL AUDIO COLLECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/082181
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of mobile communications. Provided are a spatial audio collection method and apparatus. The method comprises: arranging a plurality of groups of mutually orthogonal microphone arrays in a UE, and performing differential beam processing on microphone signals acquired by the microphone arrays, so as to acquire a spatial audio signal. By means of the present disclosure, mutually orthogonal microphone arrays formed by miniature microphones that use a beam technique may be used, and the size of a spatial audio collection system is controlled to be within certain dimensions, such that the spatial audio collection system is built in an existing mobile device, and a pickup system that can be built in a mobile intelligent device is formed; in addition, the directivity of the microphone arrays is controlled by means of a differential beam technique, and additional electro-acoustic and acoustic hardware requirements are reduced, thereby meeting requirements for the mobile intelligent device regarding collecting immersive audio when the volume of the device is controlled.
