Problems solved by technology

[0002] With the increasing popularity of the Internet, real-time voice communication applications are being used more and more widely. However, due to the influence of network status and related factors, packet loss in real-time voice communication is inevitable. Unlike video transmission, voice packet loss Poor handling will seriously degrade the experience of both parties in the call. Therefore, in order to avoid this problem, in the prior art, compensation methods based on receiver compensation are usually used to solve the above problems; Compensation technology, by generating a substitute voice similar to the lost voice packet to realize the supplementary packet operation, but due to the algorithm limitation, it can only handle small packet loss rate (<15%) and small voice packets (4-40ms ), and the accuracy of the algorithm is low, it is difficult to meet the business needs in some business scenarios, so an effective solution is urgently needed to solve this problem

Abstract

The invention provides an audio processing method and device. The audio processing method comprises the following steps: acquiring a to-be-processed audio; preprocessing the to-be-processed audio to obtain a global frequency domain frame sequence corresponding to the to-be-processed audio; constructing an audio feature set corresponding to the to-be-processed audio according to the global frequency domain frame sequence, and inputting the audio feature set into an audio processing model for processing to obtain a local frequency domain frame sequence; and generating a target audio for replacing the to-be-processed audio based on the local frequency domain frame sequence and the global frequency domain frame sequence, thereby realizing accurate compensation of the to-be-processed audio, and effectively improving compensation efficiency and compensation accuracy.

Description

technical field [0001] This specification relates to the field of computer technology, in particular to an audio processing method. This specification also relates to an audio processing device, a computing device, and a computer-readable storage medium. Background technique [0002] With the increasing popularity of the Internet, real-time voice communication applications are being used more and more widely. However, due to the influence of network status and related factors, packet loss in real-time voice communication is inevitable. Unlike video transmission, voice packet loss Poor handling will seriously degrade the experience of both parties in the call. Therefore, in order to avoid this problem, in the prior art, compensation methods based on receiver compensation are usually used to solve the above problems; Compensation technology, by generating a substitute voice similar to the lost voice packet to realize the supplementary packet operation, but due to the algorith...
