音樂解碼技術研究與音樂播放的實現(xiàn)


摘要
本文介紹研究音頻編碼解碼相關技術，并結合VC6.0編寫多媒體音樂播放器，利用軟件工程原理，采用面向對象的編程方法，其開發(fā)主要包括前臺窗體的設計和后臺源碼的實現(xiàn)兩個方面，實現(xiàn)了利用計算機進行多媒體音頻的播放.
音樂播放器開發(fā)過程總共包含了六部分，通過系統(tǒng)分析，系統(tǒng)開發(fā)的方法，系統(tǒng)開發(fā)平臺介紹，概要的設計，系統(tǒng)的規(guī)劃和設計，系統(tǒng)設計，分別介紹了從分析到開發(fā)到系統(tǒng)的設計與測試的整個音樂播放器的生成過程。系統(tǒng)分析介紹了播放器的播放流程，開發(fā)背景發(fā)展前景，開發(fā)工具概要，開發(fā)系統(tǒng)的最低配置等。系統(tǒng)開發(fā)的方法介紹了音樂播放器的具體的開發(fā)方法和如何選擇的開發(fā)方法。系統(tǒng)開發(fā)平臺的介紹，具體介紹了VC6.0主要界面和使用方法，其中包括常用工具具體位置與使用方法和工作區(qū)的生成，項目的創(chuàng)建、項目中文件的添加刪除、項目的編譯、項目的測試等。后邊幾部分和附錄介紹了系統(tǒng)規(guī)劃與分析，應用程序主界面，數(shù)據(jù)庫的生成，代碼的編寫與功能的實現(xiàn)，系統(tǒng)的編譯與運行，最終實現(xiàn)了音樂播放器的功能，能對歌曲音樂進行播放和控制。

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.
