音樂(lè)解碼技術(shù)研究與音樂(lè)播放的實(shí)現(xiàn)


摘要
本文介紹研究音頻編碼解碼相關(guān)技術(shù)，并結(jié)合VC6.0編寫(xiě)多媒體音樂(lè)播放器，利用軟件工程原理，采用面向?qū)ο蟮木幊谭椒ǎ溟_(kāi)發(fā)主要包括前臺(tái)窗體的設(shè)計(jì)和后臺(tái)源碼的實(shí)現(xiàn)兩個(gè)方面，實(shí)現(xiàn)了利用計(jì)算機(jī)進(jìn)行多媒體音頻的播放.
音樂(lè)播放器開(kāi)發(fā)過(guò)程總共包含了六部分，通過(guò)系統(tǒng)分析，系統(tǒng)開(kāi)發(fā)的方法，系統(tǒng)開(kāi)發(fā)平臺(tái)介紹，概要的設(shè)計(jì)，系統(tǒng)的規(guī)劃和設(shè)計(jì)，系統(tǒng)設(shè)計(jì)，分別介紹了從分析到開(kāi)發(fā)到系統(tǒng)的設(shè)計(jì)與測(cè)試的整個(gè)音樂(lè)播放器的生成過(guò)程。系統(tǒng)分析介紹了播放器的播放流程，開(kāi)發(fā)背景發(fā)展前景，開(kāi)發(fā)工具概要，開(kāi)發(fā)系統(tǒng)的最低配置等。系統(tǒng)開(kāi)發(fā)的方法介紹了音樂(lè)播放器的具體的開(kāi)發(fā)方法和如何選擇的開(kāi)發(fā)方法。系統(tǒng)開(kāi)發(fā)平臺(tái)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(xiàng)目的創(chuàng)建、項(xiàng)目中文件的添加刪除、項(xiàng)目的編譯、項(xiàng)目的測(cè)試等。后邊幾部分和附錄介紹了系統(tǒng)規(guī)劃與分析，應(yīng)用程序主界面，數(shù)據(jù)庫(kù)的生成，代碼的編寫(xiě)與功能的實(shí)現(xiàn)，系統(tǒng)的編譯與運(yùn)行，最終實(shí)現(xiàn)了音樂(lè)播放器的功能，能對(duì)歌曲音樂(lè)進(jìn)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.
