Abstract

The invention provides an audio coding method and device, electronic equipment and a storage medium. The method comprises the steps: carrying out voice endpoint detection of to-be-coded audio data soas to segment active audio segments and inactive audio segments in the to-be-coded audio data; for each active audio segment, using the energy value of each sub-band in each granularity of each activeaudio segment for calculating the granularity average energy of each active audio segment; determining a coding rate of each active audio segment according to the granularity average energy of each active audio segment, wherein the coding rate of the active audio segment is positively correlated with the granularity average energy of each active audio segment; for each active audio segment, performing audio coding on the active audio segment according to the coding rate of the active audio segment; and encoding the inactive audio segment obtained by segmenting the audio data to be encoded, wherein the encoding rate of each active audio segment is greater than the encoding rate of each inactive audio segment. According to the method, the coding quality can be improved, and the audio distortion after coding is reduced.

Description

technical field [0001] The present invention relates to the technical field of audio coding, in particular to an audio coding method and device, electronic equipment, and a storage medium. Background technique [0002] At present, in order to facilitate the network transmission and storage of audio, it is usually necessary to use audio coding technology to convert the original audio data into compressed data, and the amount of compressed data is less, which is conducive to saving storage space and reducing the network bandwidth required for network transmission , however, usually, audio distortion is prone to occur after encoding. Contents of the invention [0003] Based on the above-mentioned status quo, the main purpose of the present invention is to provide an audio encoding method and device, electronic equipment, and a storage medium, which are beneficial to reducing audio distortion after encoding. [0004] In order to achieve the above object, the technical solutio...
