M: Mrs. Brown looks sad these days.
W: So she does.
M: What's wrong with her?
W: Don't you know her son was ill last weekend?

Like many other parents, I am worried about that my children watch too much television. Why? Firstly, there are a lot of bad programmers on TV. They may copy what they see on it. Secondly, sitting in front of the TV set all day is bad for their eyes. Many students wear glasses because they watch TV for long hours. Also, watching TV too much makes children think little. I think it is important for children to read some books. Books will make children think more. When
I say this to my children, they just do not answer. They are too busy watching TV to answer me. So, I have decided to sell the television set. Don’t you think it is a good idea?

第一章数字音频基础知识 主要内容 ?声音基础知识 ?认识数字音频 ?数字音频专业知识 第1节声音基础知识 1.1 声音的产生 ?声音是由振动产生的。物体振动停止，发声也停止。当振动波传到人耳时，人便听到了声音。 ?人能听到的声音，包括语音、音乐和其它声音（环境声、音效声、自然声等），可以分为乐音和噪音。 ?乐音是由规则的振动产生的，只包含有限的某些特定频率，具有确定的波形。 ?噪音是由不规则的振动产生的，它包含有一定范围内的各种音频的声振动，没有确定的波形。 1.2 声音的传播 ?声音靠介质传播，真空不能传声。 ?介质：能够传播声音的物质。 ?声音在所有介质中都以声波形式传播。 ?音速 ?声音在每秒内传播的距离叫音速。 ?声音在固体、液体中比在气体中传播得快。 ?15oC 时空气中的声速为340m/s 。 1.3 声音的感知 ?外界传来的声音引起鼓膜振动经听小骨及其他组织传给听觉神经，听觉神经再把信号传给大脑，这样人就听到了声音。 ?双耳效应的应用：立体声 ?人耳能感受到（听觉）的频率范围约为20Hz~ 20kHz，称此频率范围内的声音为可听声(audible sound)或音频(audio)，频率<20Hz声音为次声，频率>20kHz声音为超声。 ?人的发音器官发出的声音（人声）的频率大约是80Hz～3400Hz。人说话的声音（话音voice / 语音speech）的频率通常为300Hz～3000 Hz（带宽约3kHz）。 ?传统乐器的发声范围为16Hz (C2)～7kHz(a5)，如钢琴的为27.5Hz (A2)～4186Hz(c5)。 1.4 声音的三要素 ?声音具有三个要素： 音调、响度（音量/音强）和音色 ?人们就是根据声音的三要素来区分声音。 音调（pitch ） ?音调：声音的高低（高音、低音），由―频率‖（frequency）决定，频率越高音调越高。 ?声音的频率是指每秒中声音信号变化的次数，用Hz 表示。例如，20Hz 表示声音信号在1 秒钟内周期性地变化20 次。?高音：音色强劲有力，富于英雄气概。擅于表现强烈的感情。 ?低音：音色深沉浑厚，擅于表现庄严雄伟和苍劲沉着的感情。 响度（loudness ） ?响度：又称音量、音强，指人主观上感觉声音的大小，由―振幅‖（amplitude）和人离声源的距离决定，振幅越大响度越大，人和声源的距离越小，响度越大。（单位：分贝dB） 音色（music quality） ?音色：又称音品，由发声物体本身材料、结构决定。 ?每个人讲话的声音以及钢琴、提琴、笛子等各种乐器所发出的不同声音，都是由音色不同造成的。 1.5 声道

12声音素材(一)基础知识 (2课时) [教学目标] 1、了解数字声音的基础知识； 2、知道常用声音设备的使用方法； 3、掌握各种数字声音文件的播放方法。 [教学重点与难点] 1、数字声音的基础知识； 2、常用声音设备； 3、声音文件的播放。 [教学手段] 多媒体演示教学、研讨法和上机探索练习 [教学过程] 前面我们化了较多时间研究了多媒体课件制作中的重要素材——图像素材，下面我们研究另一种多媒体素材——声音素材。在多媒体作品中，适当地运用声音能起到文字、图像、动画等媒体形式无法替代的作用，如调节使用者的情绪，引导、刺激观众的兴趣，引起使用者的注意；声音作为一种信息载体，其更主要的作用是直接、清晰地表达语意；因此声音能给多媒体作品带来令人惊奇的效果，还最大限度地影响展示效果。本次课主要研究数字声音的基础知识。 第一部分：数字声音基础知识 第二部分：常用声音设备 第三部分：声音文件的播放 上机作业： 1、常规声音设备有哪些？分别起什么作用？ 2、简要说明扩音原理。 3、多媒体电脑的声音设备核心是什么？它起什么作用？ 4、掌握耳麦的使用，并学会播放电脑或网络中的声音。 5、继续完成综合考试任务。
回目录 第一部分：数字声音的基础知识 声音数字化有两种：一是将模拟声音信号（波形信号）通过取样、量化、编码等过程转化为数字声音（波形文件）。二是计算机合成声音，包括语音合成和音乐合成（MIDI文件）。所有这些文件通称数字音频文件。 一、波形文件： 波形文件是声音模拟信号的数字化结果，可以通过录音获取。其形成过程是：音源发出的声音（机械振动）通过麦克风转换为模拟信号（模拟电信号），模拟电信号通过声卡的取样、量化、编码，得到数字信号（数字电信号）。所有声音如乐器、语音及自然界音效等都可以通过这种方式记录为数字声音。 ⑴数字波形文件参数： ＊采样频率：每秒钟将模拟信号转变为数字形式信息的次数。 11025Hz语音25050Hz音乐44100Hz CD效果 ＊采样位数：表示存储、记录声音振幅所使用的二进制位数，它决定声音的动态范围。若是8 位，表示采样的精度为28，即 256。 8位、16位、32位 ＊通道数：单声道、双声道 ⑵数字波形文件的大小： (采样频率×采样位数×声道 数)/8=字节数/秒 例：CD唱片的采样频率为 44.1kHz，采样位数为16位，双 声道，则一分钟的声音数据量为 ((44.1×16×2)/8) × 60=10584kB，所以，一张650M的光盘可存放60多分钟的声音。 ⑶数字波形文件的压缩：

录音技术基础知识 基本录音/多轨录音 无论是盒式磁带录音机、数码多轨录音机、硬盘录音机，还是其它录音媒体，其录音过程大致相同，目的都是将声音获取到缩混带上。 做此工作，录音工程师采用两个步骤： 1、多轨录音——各种乐器和人声的录音与叠加录音的过程，每种录音都有各自的“音轨”。 2、多轨缩混——将这些多轨内容同步录在一组立体声轨上（“母带录音”），可以用某种播 放系统如CD播放机或磁带卡座等进行再制作。 录音基础/多轨录音 多轨录音指多种乐器或人声的互相“叠加”，以便在播放任意一种音色时，同时听到其它的音色。有的录音设备具备将不同乐器录在每个“轨”上的能力。多轨录音好比将16个盒带录音机的磁带并列在一起。就成为16轨磁带（实际32轨，因为盒式磁带是立体声，有两个轨），从而具备了每轨录制不同乐器的潜力。 换言之，假如您为一个鼓手、一个贝司和一个伴奏吉他手弹奏的曲子录音，用一台多轨录音机将每种乐器录在各自轨上。由于是一起演奏的曲子，音符要互相合拍，播放时，听起来仍好象几个乐手在一起演奏一般。如果您要在歌曲中加入一个主音吉他，既然每个乐器都录在各自音频上，就要先播放前三个轨，使吉他手在第四轨上录制主音吉他时，能与其它乐器“合拍”。这个过程就叫叠加。 按传统方式，录音师要先录制“节奏轨”，包括：鼓、贝司、伴奏吉他、键盘以及一个将被替换的主音人声，所有都录在一起。下一步，录音师开始做叠加，加入其它节奏，主声部，背景人声，所有其它乐器，最后录制主音人声。而现代录音方式通常是一次制作一个轨，按排序的乐器、鼓的循环，或者人声开始录音。 关键点是最终你的乐器必须被同时录制在一起。一旦完成后，混音过程才能开始。 录音基础/多轨缩混 缩混的目的是将你所录制的轨道缩到两个轨道（立体声）上或一个轨（单声）上。这样就可以在传统的播放系统如卡带或CD播放机上今昔播放了。 按传统方法，多轨录音机连在多通道的调音台上，这样每一个轨在调音面板上都可以被单独进行处理了。换句话说，多轨录音机的每一个输出都连接到调音台的每一个输入通道上，从那里再进行合并，成为单一的立体声输出。这个立体声的输出可以连接到母带处理机上录制立体声信号。 在合并许多通道到两个通道时，调音台还处理其它一些重要工作，如： -调节乐器的频率内容，一般称为EQ。 -给乐器增加效果，如混响，回声或合唱。 -调节每一轨的音量，保证不会有单独的乐器音量太过于大或者小。 如今，多轨录音机，多通道调调音台，均衡和效果器上的所有功能都可以集中在一个装置上。而且还可以用光盘刻录机、数码录音机或硬盘作为母带处理机。当然重要的是您的曲子中的所有的乐器都被录音、加工、缩混最后成为一种媒介而被大众听到。 一般连接端子 输入端子 在开始录音之前，你需要将乐器或者是话筒连接到录音机或调音台的输入部分。可能你会注
2019年高考广东听说考试真题A录音稿及答案 Part B Tapescript: W: Hi, Tom! Where have you been during the holiday? M: Oh, I spent fifteen days with my family back in my hometown. W: That must be very relaxing. You were in your comfort zone again. M: You are right. Staying with family and relatives is always quite comfortable, especially when you have a big family. W: Oh… So you’ve grown up in a big family? How many brothers and sisters do you have? M: I have three brothers and four sisters. 三问部分： Question 1: What was it like growing up in a big family?/ How did you like growing up in a big family?/ What was growing up in a big family like? Answer 1: I love having such a big family. There were many sweet memories about those years growing up with my brothers and sisters. We played games together and went to school together and it was our family tradition to give everybody a surprise on his or her birthday. But at times, it could be a little crowded as we all live together in a small house when we were young. Question 2: What was the most difficult part?/ What was the hardest part?/ What was the toughest part?/ What was the most difficult thing?/ What was the hardest thing?/ What was the toughest thing? Answer 2: I think it was that we didn’t have enough money to make sure that everybody ate well and dressed well. My elder brothers and sisters had a little tougher life than we did, because they had to work a lot to help with the family income. Question 3: Are younger children luckier than the elder children?/ Are younger children more fortunate than the elder children? Answer 3: Yes. I think for the most part, the younger ones are luckier, because they have more people to look up to and tell them right from wrong, which is a great help. As for the elder children, they have to help support the family and look after the younger ones. So usually, they have more responsibilities. 五答部分： Question 1: Where did Tom spend his holiday? Answer 1: In his hometown./ He spent his holiday in his hometown. Question 2: How many sisters does Tom have? Answer 2: Four./ Four sisters./ He has four sisters. Question 3:What was Tom’s family tradition? Answer 3: To give everybody a surprise on his or her birthday. Question 4:Why did Tom’s elder brothers and sisters have a tougher life?

Adobe aduition 数字艺术中心 Adobe aduition 简介 Adobe Audition v1.5可以理解为是COOLEDIT pro的最新升级，出品COOLEDIT的公司两年前卖给了ADOBE公司（大名鼎鼎的PHOTOSHOP就是出自ADOBE），著名的音频编辑软件COOLEDIT PRO 2.1也随之改名为Adobe Audition v1.0。这个最新的版本是ADOBE接手后第一次对这个软件进行的较大 升级，增加了一些功能，值得关注，建议大家升级。 Adobe Audition1.5软件提供专业化音频编辑环境。Adobe Audition专门为音频和视频专业人员设计，可提供先进的音频混音、编辑和效果处理功能。Adobe Audition具有灵活的工作流程，使用非常简单并配有绝佳的工具，可以使您制作出音质饱满、细致入微的最高品质音效。 数字音频 数字音频技术是利用数字技术处理声音的方法 （1）数字音频技术和MIDI音乐的区别 数字音频技术是用数字化的手段还原真实的音乐MIDI技术主要是用MIDI软件将乐谱输到软件中然后选择一个音色，做成音乐。 （2）数字音频的用途： 1.唱片制作 现在99%的唱片制作流程中都有数字音频的参与，无论是CD,VCD,DVD,还是电脑的MP3音乐，数字音频都是必不可少的一个重要环节。可以说没有数字音频，就没有现在市场上的数量众多的音乐成品，唱片工业也不可能如此的繁荣。 2.影视配音配乐 数字电影已经遍地开花，而数字化的声音也是数字电影一个不可缺少的重要组成部分。每年全世界公开发行的影视作品中的配音和配乐大多都是通过数字音频制作的，影视音乐产生的产业价值与流行音乐比起来毫不逊色，许多大牌音乐人不做流行音乐，只做影视音乐。足见影视音乐的商业价值。影视音乐是我们这次课的重点，我们到最后每个组都要做一个自己的作品，下面我们就影视音乐方面做一个扩展 影视音乐的形式: 影视音乐就其声源而言，一般可分为有声源音乐和无声源音乐两种形式。 ①有声源音乐，亦称画内音乐、客观性音乐，即影视片中出现的音乐是画面中的声源所提供的，如正歌唱的人、演奏的乐器、开着的收音机、录音机、电视机等。此时音乐与画面保持同一现实世界的节奏。它在加强影视片的时代感、渲染环境气氛和直接参与情节等方面有其独到之处。运用有声源音乐应注意音乐的音质与画面小所提供的声源相一致。不过，有声源音乐一旦进入剧中人物的内心世界，便由原来的逼直性音乐走向假定性音乐，这时即使所听到的音乐与声源不符也是可以的。 ②无声源音乐，亦称画外音乐、主观性音乐，即影视片中的音乐并非来自画面所提供的现实世界，而是创作者对画面这一客观世界的感受，是根据塑造人物性格和谊染环境气氛等需要设计的，并以其特有的深度和强度来补充画画不易表达的情绪和感情影视音乐虽是分段陈述的，但仍有一定的承续性，因此，无声源音乐的运用，不仅要有内在的根据，而且要打前后衔接的照应。 音乐创作一经同影视艺术结合，就不再属于单纯音乐的范畴，而形成一个新的概念。它既不是独立的音乐作品，又不是仅仅为了说明画面内容的被动因素，而是发挥音乐的特性成为综合艺术中不可缺少的艺术表现手段。在这里，音乐同画面相辅相成、殊途同归，从不同的侧面达到了共同为作品主题服务的目的。
