局域網(wǎng)的語(yǔ)音通信(VC)畢業(yè)論文.doc

-I-摘要本論文討論了Windows環(huán)境下局域網(wǎng)語(yǔ)音聊天程序的設(shè)計(jì)思路和設(shè)計(jì)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(wù)器/客戶端)構(gòu)架,用socket編程設(shè)計(jì)網(wǎng)絡(luò)通訊。界面設(shè)計(jì)部分采用WindowsMFC框架。分析了服務(wù)器端應(yīng)用系統(tǒng)軟件的結(jié)構(gòu)和功能，闡述了系統(tǒng)的實(shí)現(xiàn)方法和實(shí)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(shí)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(diǎn)的說明了語(yǔ)音通信的設(shè)計(jì)思路、難點(diǎn)技術(shù)和解決方案。關(guān)鍵字：局域網(wǎng)；語(yǔ)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(jiǎn)介.11.2VisualC+程序設(shè)計(jì).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(jì)算機(jī)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(jī)/服務(wù)器模式.102.4Winsock介紹.112.4.1Winsock的基本概念.112.4.2Winsock的編程特點(diǎn).122.4.3Winsock基本的API.132.4.4異步選擇機(jī)制.182.4.5winsock編程原理.182.5系統(tǒng)實(shí)現(xiàn)的功能及設(shè)計(jì)要求.212.5.1系統(tǒng)實(shí)現(xiàn)的功能.212.5.2設(shè)計(jì)要求.22第3章系統(tǒng)分析與設(shè)計(jì)233.1設(shè)計(jì)思想.233.2界面設(shè)計(jì).253.3軟件設(shè)計(jì)要點(diǎn).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(shí)現(xiàn)29-IV-4.1連接服務(wù)器
