Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments It is a part of the embodiments of the present disclosure, but not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0042] In the prior art, when encoding and decoding audio data, the audio data is generally encoded and decoded in a linear predictive analysis modeling manner. However, because coding and decoding using the linear predictive analysis modeling method will have more residual information, it is difficult to realize coding and decoding lower th...

Abstract

The embodiment of the invention provides an audio processing method and device and electronic equipment. The method comprises the steps of obtaining to-be-processed audio data, wherein the to-be-processed audio data comprises at least one audio frame; extracting audio feature information corresponding to each audio frame, and performing quantitative compression based on the audio feature information corresponding to each audio frame to obtain encoded audio data; and sending the encoded audio data to a second device, so that the second device decodes the encoded audio data by using a target up-sampling network model to obtain the to-be-processed audio data so as to effectively realize encoding and decoding under a low bit rate and improve the use satisfaction of a user.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of audio technology, and in particular, to an audio processing method, device, and electronic device. Background technique [0002] In the audio transmission process, it is often necessary to encode and decode the audio, that is, the encoding end needs to first compress and encode the audio to obtain the corresponding encoded audio. After the encoded audio is obtained, the encoded audio is sent to the decoding end, so that the decoding end decodes the encoded audio and recovers the audio. [0003] At present, when encoding and decoding audio data, the audio data is generally encoded and decoded in a linear predictive analysis modeling manner. However, due to the use of linear predictive analysis and modeling methods for encoding and decoding, there will be more residual information, and it is difficult to achieve low bit rate encoding and decoding. Therefore, there is an urgent need for a ...
