Document Type and Number:
WIPO Patent Application WO/2022/110723
Kind Code:
A1
Abstract:
An audio encoding and decoding method and apparatus, and a readable storage medium. The encoding method comprises: selecting a first target virtual speaker from a preset virtual speaker set according to a current scene audio signal (401); generating a first virtual speaker signal according to the current scene audio signal and attribute information of the first target virtual speaker (402); and encoding the first virtual speaker signal to obtain a code stream (403). By means of the encoding method, the amount of data to be encoded is reduced, so that the encoding efficiency is improved.
