Problems solved by technology

[0004] However, due to the different compression methods of MP3, AAC, AC3, EAC3 and other files, when using the same audio frame number to transmit different types of files, the size of buffers required by each file is quite different, so use fixed-size buffers for audio compression When the data is stored, it will cause a waste of memory. In addition, the fixed buffer size will make the audio compression data in the boundary case, and the corresponding audio frame data needs to be split. In this case, the split audio frame needs to be recorded. The serial number of the data and the position of the split, which cause the complexity of file parsing and decoding, and increase the processing burden of the CPU and DSP

Abstract

The embodiment of the invention discloses an audio processing method. According to the method, sizes of cache spaces can be dynamically adjusted for storing audio data, the decoding complexity is reduced, and processing loads of a CPU (Central Processing Unit) and DSP (Digital Signal Processing) are reduced. The method comprises the steps of receiving an audio playing request, wherein the audio playing request is used for making a request for playing a first audio file; analyzing a first file type of the first audio file in response to the audio playing request; analyzing an audio feature parameter of the first audio file when the first file type is not stored in a preset mapping table of file types and caches and calculating a first cache space according to the audio feature parameter; and decoding the first audio file according to the size of the first cache space, thereby obtaining a first playing file.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an audio processing method, a terminal and a storage medium. Background technique [0002] In the era of mobile Internet, with the promotion and popularization of smart terminals, users are constantly pursuing high-quality audio-visual experience. High bit rate, multi-channel, and lossless audio sources have gradually become standard equipment for smart terminals. Increasingly demanding. Currently, moving picture experts compress standard audio layer 3 (MP3, Moving Picture ExpertsGroup Audio Layer III), advanced audio coding (AAC, advanced audio coding), audio coding 3 (AC3, AudioCoding3), enhanced audio coding (EAC3, Enhanced AC -3) and other audio coding technologies, as today's more popular digital audio coding and lossy compression formats, can greatly reduce the amount of audio data, and for most users' hearing experience, the sound quality of the replayed audio i...
