-I-摘要本論文討論了Windows環(huán)境下局域網(wǎng)語音聊天程序的設(shè)計思路和設(shè)計方法。其中網(wǎng)絡(luò)通信部分采用流行的TCP/IP協(xié)議。程序采用典型的C/S(服務器/客戶端)構(gòu)架,用socket編程設(shè)計網(wǎng)絡(luò)通訊。界面設(shè)計部分采用WindowsMFC框架。分析了服務器端應用系統(tǒng)軟件的結(jié)構(gòu)和功能，闡述了系統(tǒng)的實現(xiàn)方法和實現(xiàn)思路。硬件上只需要一塊雙DMA通道的聲卡（目前的聲卡大多支持雙DMA通道）和一支耳麥，其余全部由軟件編程實現(xiàn)。論文主要介紹了本課題的開發(fā)背景，所要完成的功能和開發(fā)的過程。重點的說明了語音通信的設(shè)計思路、難點技術(shù)和解決方案。關(guān)鍵字：局域網(wǎng)；語音通信；socket；C/S構(gòu)架-II-AbstractThisarticlediscusseshowtodesignanddevelopaLANchattingprograminWindowsenvironment.NetcorrespondencepartusespopularTCP/IPagreement.TheprocedureusesthemodelC/S(server/Clientside)skeleton,programsthedesignnetworkcommunicationwithsocket.ThecontactsurfacedesignpartusesWindowstheMFCframe.Hasanalyzedtheserverendapplicationsystemsoftwarestructureandthefunction,Elaboratedthesystemrealizationmethodandtherealizationmentality.OnthehardwareonlyneedsthedoubleDMAchannelsoundcard(thepresentsoundcardmostlytosupportthedoubleDMAchannel)togetherandjournalwheat,othercompletelyprogramtherealizationbythesoftware.Thepapermainlyintroducedthistopicdevelopmentbackground,mustcompletefunctionanddevelopmentprocess.Keyexplanationpronunciationcorrespondencedesignmentality,difficulttechnologyandsolution.Keywords:thelocalarea；networkpronunciationcorresponds；socketC/Sskeleton-III-目錄第1章概述11.1開發(fā)環(huán)境簡介.11.2VisualC+程序設(shè)計.31.3低層波形音頻.4第2章WINDOWSSOCKET網(wǎng)絡(luò)編程的研究82.1計算機網(wǎng)絡(luò)的體系結(jié)構(gòu).82.2TCP/IP的體系結(jié)構(gòu).92.3客戶機/服務器模式.102.4Winsock介紹.112.4.1Winsock的基本概念.112.4.2Winsock的編程特點.122.4.3Winsock基本的API.132.4.4異步選擇機制.182.4.5winsock編程原理.182.5系統(tǒng)實現(xiàn)的功能及設(shè)計要求.212.5.1系統(tǒng)實現(xiàn)的功能.212.5.2設(shè)計要求.22第3章系統(tǒng)分析與設(shè)計233.1設(shè)計思想.233.2界面設(shè)計.253.3軟件設(shè)計要點.263.3.1客戶端.263.3.2音頻數(shù)據(jù)處理的CSound類.273.3.3主框架程序.27第4章系統(tǒng)的實現(xiàn)29-IV-4.1連接服務器
