Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] Before explaining the embodiment of the present application in detail, some nouns that may be involved in the embodiment of the present application are firstly explained.

[0038] Audio frame: frame, also known as data frame.

[0039] An audio frame is a fixed-length or variable-length data block generated by compressing audio data of a certain length by a specific compression algorithm. Such a data block is called a frame.

[0040] As an example, the playback duration of an audio frame may be 23.32ms (milliseconds), 46.64ms or 128ms, etc., which is not specifically limited in this embodiment of the present application.

[0041] The aforementioned audio data before compression processing refers to PCM (Pulse Code Modulat...

Abstract

The application discloses an audio decoding method and device, a storage medium and equipment, and belongs to the technical field of multimedia. The method comprises the steps: after a multimedia fileis started to be played, acquiring audio data to be decoded within a first duration after playing is started; performing decoding processing on the audio data based on a software decoding mode, and performing verification processing on the obtained first decoded audio data to obtain first verification data; performing decoding processing on the audio data based on a hardware decoding mode, and performing verification processing on the obtained second decoded audio data to obtain second verification data; and when the first check data match the second check data, decoding the audio data to bedecoded after the first duration based on a hardware decoding mode. According to the application, on the basis of improving the decoding efficiency, the problem of audio noise generated by decoding errors is solved.

Description

technical field [0001] The present application relates to the field of multimedia technology, and in particular to an audio decoding method, device, storage medium and equipment. Background technique [0002] As people have higher and higher requirements for images and sounds, in high-definition digital television and digital movies, not only high-quality video images, but also high-quality stereo audio should be provided. Based on this demand, digital methods are often used to record audio nowadays to replace the original analog recording method. However, for digital audio, the amount of data is usually very large, which not only requires a large amount of storage space, but also requires a large amount of bandwidth during transmission. In order to solve the above two problems, audio compression technology is usually used to compress the original audio data. This process is also called compression coding; correspondingly, during the playback process, the compressed audio d...
