Audio encoding and decoding methods and equipment

Abstract

The term "encryption" refers to the methods used to encrypt and decrypt audio, and the means by which the audio is readable by a computer. This encoding method includes: selecting the most interesting target virtual speaker from a pre-set set of virtual speakers based on the current audio scene signal (401); generating the first virtual speaker signal based on the current audio scene signal and the attribute information of the first target virtual speaker (402); and encoding the first virtual speaker signal to receive the bit stream (403). With this encoding method, the amount of data encoded is reduced, improving encoding efficiency.
