Audio processing method, related device, storage medium and program product

Abstract

The embodiment of the invention discloses an audio processing method, related equipment, a storage medium and a program product, and the method comprises the steps: obtaining to-be-processed target audio data and the frequency spectrum information of the target audio data,wherein the audio missing clip exists in the target audio data, the frequency spectrum information comprises frequency spectrum features of context audio clips of the audio missing clip; performing feature compensation processing on the frequency spectrum information of the target audio data according to the frequency spectrum features of the context audio clip to obtain compensation frequency spectrum information corresponding to the target audio data; performing audio prediction by adopting the compensation frequency spectrum information to obtain predicted audio data; and compensating the audio missing clip in the target audio data according to the predicted audio data to obtain the compensated audio data of the target audio data, so that the accuracy of carrying out prediction compensation on the packet loss audio can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an audio processing method, related equipment, storage media and program products. Background technique [0002] With the continuous development of computer network technology, packet loss usually occurs during the transmission of audio data based on the Internet, resulting in the failure of part of the audio data in the transmitted audio to be received by the receiving end, thereby affecting the user's listening experience. However, the current method of compensating and recovering packet loss audio usually adopts an autoregressive iterative prediction method, that is, a method of sequentially predicting the next sampling point based on the previous sampling point, and due to the error during the iterative prediction process, Therefore, how to improve the accuracy of audio data obtained after predicting and compensating packet loss audio has become a current researc...
