音乐解码技术研究与音乐播放的实现


摘要
本文介绍研究音频编码解码相关技术，并结合VC6.0编写多媒体音乐播放器，利用软件工程原理，采用面向对象的编程方法，其开发主要包括前台窗体的设计和后台源码的实现两个方面，实现了利用计算机进行多媒体音频的播放.
音乐播放器开发过程总共包含了六部分，通过系统分析，系统开发的方法，系统开发平台介绍，概要的设计，系统的规划和设计，系统设计，分别介绍了从分析到开发到系统的设计与测试的整个音乐播放器的生成过程。系统分析介绍了播放器的播放流程，开发背景发展前景，开发工具概要，开发系统的最低配置等。系统开发的方法介绍了音乐播放器的具体的开发方法和如何选择的开发方法。系统开发平台的介绍，具体介绍了VC6.0主要界面和使用方法，其中包括常用工具具体位置与使用方法和工作区的生成，项目的创建、项目中文件的添加删除、项目的编译、项目的测试等。后边几部分和附录介绍了系统规划与分析，应用程序主界面，数据库的生成，代码的编写与功能的实现，系统的编译与运行，最终实现了音乐播放器的功能，能对歌曲音乐进行播放和控制。

Research of the audio frequency decoding engineering and realize of the audio frequency player
Abstract
                                                            
This article introduces the correlation technique of audio frequency code and decoding. Through writing the audio frequency player of the multimedia with VC6.0, utilize soft project principle, adopt facing target programming method, it develops to be mainly including the design of the body of window of the front desk and backstage supporter's source code realization two respect, have realized utilizing the computer to carry on the broadcasting of audio frequency of multimedia.
System this develop course include six chapter altogether, through network analysis, method that system develops, the introduction to the systematic developing platform, the design of outline, systematic planning and design, the system is designed, has introduced and turned into the course to the systematic design and whole audio frequency player of test from analyzing to developing separately. Chapter one introduces the procedure of broadcasting of the player, develop the development prospect of the background, the outline of the developing instrument, develop systematic disposing etc. the most low. And approach how to choose that chapter two has introduced player concrete development approach of audio frequency. Chapter three is the introduction to the systematic developing platform, introduce VC6.0 main interface and operation method specifically, including the formulation of concrete position of daily tool and operation method and workspace, establishment, project Chinese piece of project add deletion, compiling test of event of event etc. Odd chapter and appendix recommend system plan and analyze application program live in interface finally, the formulation of the database , the code one writes and the realization of the function, the systematic one compile and is issued, realize the function of the player of the audio frequency finally, can broadcast and control the song music .
Keywords: Audio frequency decoding； The software system; VC6.0 ; audio frequency broadcast; Develops the even project; Project; resources document.
