Problems solved by technology

[0003] However, due to cost considerations, the RAM capacity of electronic playback devices is very limited, and most of the capacity must be allocated for running more basic and important programs, so the capacity allocated for buffering audio file information is very limited.
[0004] Due to the very limited RAM capacity of the car, the current car multimedia playback device uses one-time reading when scanning songs. The number of songs is fixed and limited, and song files exceeding this number cannot be read

Embodiment Construction

[0042] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0043] like figure 1 As shown, the embodiment of the present invention provides a kind of audio file loading method, comprises:

[0044] Step 1. Set the total length of the audio file information cache unit.

[0045] In this embodiment, the total length of the audio file information cache unit is set to store 500 pieces of audio file information.

[0046] Step 2, the audio file information cache unit is divided into several functional buffer areas, and the functional buffer area includes the front buffer area, the front list buffer area behind the front buffer area, and the rear end buffer area. buffer, a back list buffer before the back buffer, and a playback buffer between the front list buffe...

Abstract

The invention provides an audio file loading method. An audio file information caching unit is equally divided into a plurality of functional caching areas; according to the capacity of the functionalcaching areas, the total number of the audio file is segmented into blocks to generate a storage node list; according to the storage node list, each caching area is refreshed; then, according to thereceived audio file information, the caching area is refreshed. By use of the method, the caching area is dynamically regulated, and relatively small RAM (Random Access Memory) space is used for reading the audio file information without a number limitation.

Description

technical field [0001] The invention relates to the technical field of audio file management, in particular to an audio file loading method. Background technique [0002] General electronic playback devices have ROM and RAM. ROM is used to store system programs and user data such as music, movies, and e-books. RAM is the running memory of electronic playback devices and is used to temporarily store data. Generally speaking, RAM capacity The larger the size, the more applications can run at the same time. [0003] However, due to cost considerations, the RAM capacity of electronic playback devices is very limited, and most of the capacity must be allocated for running more basic and important programs, so the capacity allocated for buffering audio file information is very limited. . [0004] Due to the very limited RAM capacity of the car, the current car multimedia playback device uses one-time reading when scanning songs. The number of songs in is fixed and limited, and ...
