Embodiment Construction

[0021] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The main solution of the embodiment of the present invention is: a single sound file is sliced ​​and separated into different sub-files, and each sub-file is re-sampled using different sampling rates according to requirements to generate sub-files with different sampling rates. The sub-files of the program are bound according to the sequence of program calls to form an association group, so that they can be spliced ​​into a whole in the program for playback. Therefore, through the differentiated sampling rate of a single sound file, the problem of capacity occupation of a single sound file can be further optimized, and the memory footprint can be optimized according to user needs, so as to reduce the occupation of system capacity and memory by sound files, and improve system performance.

Abstract

The invention relates to a file processing method and device. The method comprises the following steps: obtaining a sound file, and slicing the sound file to divide the sound file into different sub-files; resampling all sub-files by different sampling rates to generate the sub-files of different sampling rates; and binding the sub-files with different sampling rates according to a program calling sequence to form a related group. The system volume and memory occupation of single sound file can be reduced through the differentiation sampling rate of the single sound file.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a sound file processing method and device. Background technique [0002] At present, when processing sound files used in various terminal applications (such as games), different sampling rates can only be used for different sound files, so as to meet the requirements of optimizing file occupation capacity and memory. However, since a single sound file can only use a fixed single sampling rate, the volume occupied by the sound file and memory is still relatively large. Contents of the invention [0003] Embodiments of the present invention provide a file processing method and device to reduce the occupation of system capacity and memory by sound files. [0004] The embodiment of the present invention proposes a file processing method, including: [0005] Obtain the sound file, slice the sound file, and separate it into different sub-files; [0006] Use different samp...
