Cool Edit 教程--Cool Edit 的安装及参数设置

Cool Edit 教程--Cool Edit 的安装及参数设置

Cool Edit 教程--Cool Edit 的安装及参数设置首先,我们要做好准备工作。

把你的耳机作为监听音箱(此步的意义就是说用耳机来听伴奏音乐,否则在你录音时会录入音乐和人声的混合声音),把你的mic调试好。

然后下载我们要用到的工具COOL EDIT PRO 2.0及其插件。

现在很多的音乐制作人都在使用这个超级工具。

闲话少说,与本次介绍给大家无关的不提,我们现在开始。

1、安装好cooledit pro 2.0后,再把插件安装到安装目录下的子目录中,新建一个名曰“DX”的文件夹,把所有的插件都安装释放到这里。

2、打开cooledit pro 2.0后,会自动建立一个新的工程。

界面如下:大家看到,标注的红色1是多轨与单轨切换的按钮。

红色标注2是表示你在录音时要点亮“R”“S”“M”中的“R”,这表示此轨是在录音范围之中。

点击录音键(红色标注3)就可以开始录下你的声音了。

在录音之前还需调整你的“声音与音频属性”,双击电脑桌面右下角的音量图标,打开后点选项中的属性如图:需要把录音项打勾,在MIC一栏中选中,其它的不要选择,因为我们要录的只是自己要歌唱的声音。

3、在第三轨处点亮R,点击录音键,不要出声,先录下一段空白的噪音文件,不需要很长,录制完后双击进入单轨模式,选择效果-噪音消除-降噪器,选择噪音采样,点击“关闭”。

回到多轨模式下删除此轨。

另,也可以在单轨下截取音轨空白的部分获取噪音进行降噪。

4、右键单击第一轨,插入一个音频文件,注意,这个音频文件就是你的音乐伴奏文件,可以是mp3,也可以是wav等其它音乐文件的格式。

5、在第二轨处,把R点亮,点击下面的红色录音键就可以开始跟唱了。

不要忘了准备歌词和熟悉歌曲的旋律,要不然录出来的东西可是……嘿嘿6、录制完成之后,你可以听听你录下的声音是不是干巴巴的?很难听吧?呵呵,都这样,没有加任何效果嘛。

好,现在我们来给你的声音进行一下润色吧。

右键点击你录制声音所在的轨道,点击波形编辑进入单轨模式。

一步一步教你使用cooledit

一步一步教你使用cooledit

一步一步教你使用cooledit一步一步教你使用cooledit系统介绍一下用Cooledit pro 2.1录制自唱歌曲的一个全过程,希望对喜欢唱歌,想一展歌喉的朋友有所帮助。

录制原声录音是所有后期制作加工的基础,这个环节出问题,是无法靠后期加工来补救的,所以,如果是原始的录音有较大问题,就重新录吧。

1、打开CE进入多音轨界面右击音轨1空白处,插入你所要录制歌曲的mp3/wma伴奏文件(图1)。

(图1)2 、选择将你的人声录在音轨 2 ,按下“R”按钮。

(图 2 )(图 2 )3 、按下左下方的红色录音键,跟随伴奏音乐开始演唱和录制。

(图 3 )(图 3 )4 、录音完毕后,可点左下方播音键进行试听,看有无严重的出错,是否要重新录制(图 4 )(图 4 )5 、双击音轨 2 进入波形編辑界面(图 5 ),将你录制的原始人声文件保存为 mp3pro 格式(图6 图7 ),以前的介绍中是让大家存为 wav 格式,其实 wma/mp3 也是绝对可以的,并且可以节省大量空间。

(图 5 )(图 6)(图 7 )(注)需要先说明一下的是:录制时要关闭音箱,通过耳机来听伴奏,跟着伴奏进行演唱和录音,录制前,一定要调节好你的总音量及麦克音量,这点至关重要!麦克的音量最好不要超过总音量大小,略小一些为佳,因为如果麦克音量过大,会导致录出的波形成了方波,这种波形的声音是失真的,这样的波形也是无用的,无论你水平多么高超,也不可能处理出令人满意的结果的。

另:如果你的麦克总是录入从耳机中传出的伴奏音乐的声音,建议你用普通的大话筒,只要加一个大转小的接头即可直接在电脑上使用,你会发现录出的效果要干净的多。

降噪是至关重要的一步,做的好有利于下面进一步美化你的声音,做不好就会导致声音失真,彻底破坏原声。

单单这一步就足以独辟篇幅来专门讲解,大家清楚这一点就行了。

1. 点击左下方的波形水平放大按钮(带 + 号的两个分别为水平放大和垂直放大)放大波形,以找出一段适合用来作噪声采样波形(图8 )。

cooleditor使用02

cooleditor使用02
在第一轨中按鼠标右键点击Insert项中的Wave from File,选择第1步中处理好的消除人声后的音频文件插入第一轨,再在第二轨中按鼠标右键插入均衡处理后的音频文件
插好之后,播放听一下,是不是还可以?不行的话,就分别调大这两轨的音量
最后,如果满意了,那么在Edit菜单中选择Mix Down to Track项中的 All Waves,将两轨混合输出为另一个文件。等混音结束后,将它存盘即可使用了
显然,在描述这些奇妙的音效方面,语言未免显得有些苍白无力,最好的学习方法,就是反复试用、反复体会它们。你可以录制或打开一个现成的声音文件,然后,点击菜单Transform,选择一种音效,调整音效的各项设置,或直接选用一种预置效果,按下OK按钮,听听看,不满意用Undo还原重来。
注意,如果你使用的是Cool Edit 2000试用版,那么,每次启动只能选用两类功能,因此,要想试所有音效,你不得不反复启动程序,并选择不同的功能(免费午餐并不好吃呵^_^)。
注意:如果你正在使用Cool Edit 2000的试用版,那么,只允许保存一分钟长度的MP3文件(Syntrillium公司是不是太小器了?)。不过,相信聪明的读者可以用Windows剪贴板来饶过这道弯,具体操作就不用我说了吧?
五、如何提升Cool Edit 2000的功能?
使用Syntrillium公司提供的以下插件,可以将Cool Edit 2000的功能提高到一个新的档次,需要的话,可到该公司网站(),免费下载试用版。
三、如何用Cool Edit 2000添加音效?
添加音效,是Cool Edit 2000最激动人心的功能。在Cool Edit 2000的菜单Transform(变换)下,有20个子菜单,通过它们,用户可以方便地制作出各种专业、迷人的声音效果。如Reverb(余音),可以产生音乐大厅的环境效果;Dynamics Processing(动态处理),可以根据录音电平动态调整输出电平;Filters(过滤器),可以产生加重低音、突出高音等效果;Noise Reduction(降噪),可以降低甚至清除文件中的各种噪音;Time/Pitch(时间/音调),能够在不影响声音质量的情况下,改变乐曲音调或节拍等等,最神奇的是Brainwave Synchronizer(脑波同步器),可以通过立体声耳机,产生有助于入睡、放松,甚至思考的音乐,真是绝了!

CoolEdit 2.0的安装和设置技巧如何安装和设置CoolEdit pro 2.0 (以下简称COOL)。

首先,我们要从网上下载 CoolEdit pro 2.0 的安装包,其中应该包括以下几个东西(图1):每个东东的用途都已经写在图上了,大家可以自己看一下。

下面我们就开始安装 CoolEdit pro 2.0 了。

首先运行主安装程序cooledit2setup.exe(图2),然后我们就可以看到Cool的安装界面,下面我们一步一步进行安装。

首先是cool的版权信息,我们直接选择同意(Accept license agreement),然后下一步(continue)(图3)。

然后是cool的欢迎信息,我们同样直接下一步(Next)(图4)。

接下来是选择cool的安装路径,如果你想更改cool的安装路径,可以点击Browse,指定你想安装到的路径。

这里我们直接点击下一步(Next)(图5)。

然后就到了cool的文件类型链接设置了,也就是只要打勾的文件,系统都会默认用cool 打开,因为其它格式都不常见,所以这里我们只把.wav的勾去掉(wav文件我们通常都用播放器打开)(图6)。

现在我们安装前的设置就完成了,点Next,开始安装,复制程序文件(图7)。

文件复制完以后,cool就安装完了,我们点击Exit完成安装(图8)。

这个时候cool会开始第一次的运行。

程序会自动搜索你的电脑上以temp为名的目录,并且提示你设置你的cool临时文件目录(图9),我们这里全部选NO,以后再设置。

然后是提示注册的对话框,因为我们等一下会注册,所以这里选择Buy Now,先进入程序。

(图10)进入程序以后,会有一个在线注册的提示框,直接点取消。

(图11)到这里,cool的第一次启动就完成了,然后我们把cool关掉。

接下来我们开始给cool注册,运行注册机cep2reg.exe。

(图12)同样的,选择Accept,进入下一步。

5、处理后的音频不会完全消除人声,但还是有效的。
修整换气声
由于歌手的紧张或话筒的摆放等其它因素,会造成急促或不自然、或较大的换气声,完全静音更不自然,这就需要录音师的处理了!
1、进入单轨模式,选中不自然的呼吸声前端部分(如图)
2、选择“效果”菜单下的“波形振幅”--“音量包络”。
有时还会有这样的现象,想要给网上下载的伴奏降噪,但整首歌曲没有空白区,根本无法选择一段纯噪音采样,如果要给这样的音频降噪,就必须根据自己的经验,输入参数一次次的聆听降噪了。 天!不要让我碰到这样的事情。
录制演唱专辑所需基本软件
1、录音软件:COOL EDIT 2.1
这是一款人气很旺的多轨录音软件,也算是专业的操作平台。相比amplitude2496和等录音软件要简单多了,用它录音合成对于业余爱好者是绰绰有余了。
3、让Cool edit搜索检测安装的效果器
打开Cool edit2.1,单击“单轨模式”(如图)
进入单轨模式后选择“效果”菜单,执行“刷新效果列表”(如图)
有很多网友抱怨这一部容易死机,建议死机后关闭cool,用“结束任务”,再重新启动Cool edit,再来一次,基本上没问题。如果还死机,重启系统再来。如果还死机,请检查系统配置。
再单击“高级”,选择性能(如图)
把硬件加速和采样质量都设为最好。同样的方式设置“录音”的首选设备。
3、设置录音音量电平
双击任务栏右下角图标,出现声音控制面板。如果你的录音源是设置的择“line in”,直接在“line in”下上下拖拉即可设置录音电平大小,一边在话筒前哼着旋律,一边打开录音软件观看录音波形,不能过大和过小。话筒放大器的设备上的话筒音量调节也可以设置录音电频,一般不要设置过小,设置到总音量的60%最好,细节在系统上调整。同时把带有话筒放大器设备上的话筒混响和均衡统统都关闭,因为人声的后期要在软件中处理,这样比一般设备的混响效果要好得多。

cool edit 教程一、降噪处理我们先做一‎个降噪的实‎例感觉一下‎它的功能。

说到降噪有‎好多种方法‎,大致上有采‎样、滤波、噪音门等几‎种。

这当中效果‎最好的应该‎是采样降噪‎法。

所以我们就‎先录取一段‎声音,再给它降噪‎。

Cool Edit 2000可‎以录入多种‎音源包括:话筒、录音机、CD播放机‎等。

将这些设备‎与声卡连接‎好。

然后,将录音电平‎调到适当位‎置,就可以准备‎录音了。

点击菜单F‎i le中的‎N ew,出现New‎wavef‎o rm对话‎框,选择适当的‎录音声道(Chann‎e ls)、分辨率(Resol‎u tion‎)和采样频率‎(Sampl‎e Rate)。

一般使用S‎t ereo‎、16-bit、44100‎H z,这是用于C‎D音质的设‎置,效果已经不‎错了点击Coo‎l Edit 2000主‎窗口左下部‎的红色录音‎按钮,开始录音,并播放CD‎音源。

完成录音后‎,点击Coo‎l Edit 2000主‎窗口左下部‎的Stop‎按钮。

Cool Edit 2000窗‎口中将出现‎刚录制好的‎文件波形图‎。

要播放它,点击Pla‎y按钮就可‎以了。

把波形放大‎后,将噪音区内‎波形最平稳‎且最长的一‎段选中(一般为没有‎音乐信号的‎间隔处)。

然后依次选‎取菜单里T‎r ansf‎o rm项中‎的Nois‎eReduc‎t ion 命令,就会弹出N‎o ise Reduc‎t ion的‎工作界面将界面中S‎n apsh‎o ts in profi‎l e的参数‎改为800‎,FFT Size的‎数值改为8‎192,Preci‎s ion Facto‎r的数值改‎为10,Smoot‎h ing Amoun‎t的数值改‎为10左右‎,这样可以达‎到比较好的‎效果。

改好各参数‎后,点击Get‎Profi‎l e from Selec‎t ion按‎钮,几秒后出现‎噪音样本的‎轮廓图关闭窗口,可以听听效‎果,噪音是不是‎没有了?不满意就再‎调调参数,因为音源与‎录音设备不‎同,所以需要反‎复的调试才‎能达到一个‎十分满意的‎效果。

Cool Edit简单使用教程最近总有很多朋友让我帮他们剪辑音乐并且问我是用什么软件弄的,想学怎么做音乐,今天我就简单的讲解一下如何利用Cool Edit进行音频的编辑一、软件的下载和安装点击这里下载Cool Edit,然后进行安装,安装很简单,就跟普通软件安装一样,直接下一步就好,这里就不多说了二、如何用Cool Edit打开音乐文件找到需要编辑的音频文件打开三、Cool Edit的两个编辑界面Cool Edit提供了两个编辑界面,一个是单音轨编辑界面,一个是多音轨编辑界面单音轨编辑界面多音轨编辑界面单音轨编辑界面主要是对单个音频文件进行编辑,在这个界面里可以进行各种效果的添加。

多音轨编辑界面主要是对多个音频文件的编辑,主要是为了实现多个音频的混合工作四、如何在两个界面间进行转换界面的转换有三种方法1、点击界面左上角的切换按钮2、点击查看标签,在下拉框中第一个实现界面切换3、快捷键F12实现切换效果四、如何将音频插入到多轨编辑界面中1、通过在单音轨编辑界面中的音频图像上右击,选择插入到多轨中3、在多轨编辑界面中在左边音频列表中左键按住音频不放拖拉到多轨中这样拖动有时不能使音频顶格,这是需要我们手动调整到顶格,cool edit多轨中的拖动与普通桌面图标的多动方法不同,并不是用鼠标左键,而是通过鼠标右键按住音频向左拖动,移动到顶格即可五、如何利用cool edit截取音乐的一部分1、首先将音乐通过上面的方法插入到多音轨编辑界面中,然后开始监听,到达你想要剪下的头部停止,我们停止的地方也许会和我们需要的地方有微差,这时就需要我们进行微调,默认视图下波普的图像不够细微,我们需要将波频图像进行放大然后微调将鼠标放在如图所示红色方框内滑动鼠标滚轮即可2、放大后在左键按住黄色虚线顶部的倒三角形进行左右调整,如果觉得鼠标动作过大可以通过键盘实现切割线(即黄色虚线)的左右位置,K是向左微调,J是向右微调,L是向右微调并选择微调区域,H为向左微调并选择微调区域,当调整到你想要的位置时,右击选择分割,即可将音乐切下,同理找到你想要音乐结束的地方分割即可。

You might think of it as a paint program for audio-- just as a paint program enables you to create images with colors, brush strokes, and a variety of special effects, Cool Edit enables you to “paint” with sound: tones, pieces of son gs and voices and miscellaneous noises, sine waves and sawtooth waves, pink noise, white noise, and brown noise-- even silence. Cool Edit also gives you a wide variety of special effects to “touch up” your sounds: reverberation, noise reduction, echo and delay, flanging, filtering, and many others. Cool Edit is both flexible and powerful. It works with dozens of audio file formats, supports files up to 1 gigabyte in size, enables you to customize any function to achieve just the effect you want and then to store your settings as a “preset”, and offers scripting and batch-processing features so that you can automate your sound-processing routines.This manual describes all the features and procedures you need to make the most of Cool Edit. Once you’ve started working with it, you’ll understand why thousands of musicians, multimedia authors and artists, scientists, telephony professionals, and audio enthusiasts around the world have chosen Cool Edit as the ultimate sound editor.But first, a few words:Cool Edit is marketed as ShareWare and registered copies should only be used on onemachine at any one time (that is, it's not nice to give out registration numbers to allyour friends, but it is OK to put it on more than one machine if only one person willbe using it on those multiple machines at a time). Demonstration (unregistered)copies can be given out to friends, posted on bulletin boards and internet (ftp/telnet)sites, and the like. If Cool Edit is distributed in any ShareWare collection (on CD,disk, or other medium), then Syntrillium should be notified.

Please see the section on Configurations if you have any problems running the program. This may be the first application you have used that takes full advantage of your PC (lots of hard disk space for temporary storage, lots of floating point math for many of the waveform editing functions, lots of data bandwidth for recording and playing - especially 44.1K 16-bit stereo CD quality audio, and lots of CPU time while crunching out the results of various waveform functions). In many ways, it is similar to a CAD package, except that the focus is on audio instead of graphic design.Please use this documentation for reference purposes, or just to learn more about digital signal processing and all the capabilities Cool Edit already has. We are committed to keeping Cool Edit up to date with current and future technologies.Syntrillium Software CorporationContentsGENERAL WORKINGS AND OVERVIEW (5)F EATURES O VERVIEW (5)H OW C OOL E DIT W ORKS (7)C ONFIGURATIONS (7)U SING C OOL E DIT (9)A S HORT C OURSE IN D IGITAL S IGNAL P ROCESSING (12)S IGNALS (OR W AVES) (12)A MPLITUDE (12)F REQUENCY (12)P HASE (13)S AMPLING (13)S OUND R EPRODUCTION (14)Q UALITY I SSUES (14)N OISE (14)F ILTERING (14)T HE FFT (14)W ORKING WITH F ILES (15)C LOSE (15)E XIT (15)N EW (15)N EW I NSTANCE (16)O PEN (16)O PEN A S (19)O PEN A PPEND (19)R E-O PEN (19)S AVE (19)S AVE A S (19)S AVE S ELECTION (19)G ENERAL P URPOSE E DITING (20)A DJUST S AMPLE R ATE (20)B YTE S WAP (20)C ONVERT (20)C OPY (21)C UT (21)D ELETE S ELECTION (21)E DIT L EFT/R IGHT (21)P ASTE (22)P ASTE S PECIAL (22)R EPEAT L AST C OMMAND (22)S ELECT E NTIRE W AVE (23)S PECTRAL/W AVEFORM V IEW (23)T RIM (23)U NDO (23)V IEWING R ANGE (24)FUNCTIONS AND SPECIAL FEATURES (25)W AVEFORM T RANSFORMATION F UNCTIONS (25)A MPLIFY (25)C HANNEL M IXER (26)C OMPRESSOR (26)D ELAY (28)D ISTORTION (29)E CHO (29)3D E CHO C HAMBER (30)E NVELOPE (33)F ILTER (33)F LANGE (34)I NVERT (35)M USIC (36)N OISE R EDUCTION (37)N ORMALIZE (39)Q UICK F ILTER (39)R EVERB (40)R EVERSE (41)S ILENCE (41)S TRETCH (42)W AVE (43)W AVEFORM G ENERATION F UNCTIONS (46)G ENERATE N OISE (46)G ENERATE S ILENCE (47)G ENERATE T ONES (47)O PTIONS (49)L OOP/P LAY T OGGLE (49)M ONITOR S OURCE (49)S ETTINGS (49)I NFO (51)F REQUENCY A NALYSIS (52)CD P LAYER (53)C UE L IST (54)P LAY L IST (55)S CRIPTS (55)B ATCH P ROCESSING (57)W AVE D EVICE S ELECTION (58)QUESTIONS AND ANSWERS (59)BRAINWAVE SYNCHRONIZATION FUNDAMENTALS (63)A BOUT C ARRIER W AVES (64)E NCODING B RAINWAVE I NFORMATION (65)A UTHORING B RAINWAVE F ILES (66)S AMPLE T HETA F ILE (67)H OW T O U SE B RAINWAVE S YNCHRONIZATION F ILES (69)R EFERENCES (69)TECHNICAL INFORMATION (72)T ECHNICAL N OTES (72)A BOUT THE A UTHOR (73)Features Overview∙Multiple instances (copies of Cool Edit) can be loaded, copied to, and pasted from in any mixture of wave formats.∙Cool Edit can synthesize just about any sound using the noise and tone generation functions along with the various wave transformation functions.∙Convert between various sample types with variable levels of quality for upsampling and downsampling.∙Any sample can be used as an “instrument” and set to music, like a dog barking Jingle Bells, or Tarzan yelling the national anthem.∙Waveforms of any size can be edited, limited only by hard drive space∙Supports PCM, Microsoft ADPCM and IMA ADPCM .WAV, Sound Blaster .VOC, raw PCM, Apple AIFF, and ASCII Text data formats.

This means that an instance of the program operates on a single continuous waveform. This, however, in no way means you have to work on only one waveform at a time. Multiple copies can be run at once by choosing File:New Instance. Use multiple copies to temporarily store waveform snippets (like having a multiple visual clipboards) or to work with more than a single waveform at a time. Since each running copy of the program is totally independent of the others, you can even play waveforms and work on one copy while the other is busy calculating.While Cool Edit is calculating, most of your CPU's time will be used for these calculations, although you can still run other Windows applications albeit a little slower. If in the middle of calculating a lengthy operation you need the processor for another task, you can suspend, or pause calculation by pressing the Pause button in the progress meter dialog (or just clicking on the blue progress meter in some versions).In general, all functions that alter existing waveform data can be found in the Transform menu, while those that create new waveform data can be found in the Generate menu. All file and main program control functions are in the File menu. All functions dealing with the general purpose editing can be found in the Edit menu. And finally, all miscellaneous functions that did not fit anywhere else are in the Options menu.Most dialogs have help [?] buttons for quick help about the current dialog. Lengthy explanations of all the functions can be looked up this way.Temporary FilesWhen Cool Edit loads a file, it is actually creating a temporary backup copy of the wave, decompressing it if necessary (which is why the size displayed in file size window can be larger than the size of the file that was loaded). All editing, transforming, generating, recording, and playing is done by using this temporary file. Most all systems are fast enough to record and play directly from disk, so the limits of RAM are removed allowing for the editing of files as large as your hard drive. Cool Edit uses the temporary directory specified in the Settings dialog. (This dialog first gets the directory from your TEMP environment variable, usually set in your AUTOEXEC.BAT file, the first time Cool Edit is run.) The temporary directory used to store Undo information can be different than the main temporary files directory. Undo and various other functions create temporary files that are all removed when every instance of Cool Edit is closed.Playing and Recording AudioCool Edit uses a multi-buffered system for recording and playing audio. The total buffer size can be specified in the Options:Settings dialog. The size is measured in seconds, and should be just slightly longer than the longest time you expect your system to be busy. The system is busy whenever you see the hourglass cursor, so this should give you some indication of the proper time to enter. If the system is busy for longer than the buffer time specified, recording or playing will stop. You will hear gaps of silence during play, and missing audio data from recording if this value is too low. For most systems, 4 seconds is fine, and 8 seconds should be more than enough.ConfigurationsCool Edit doesn't need much configuration, but for optimal performance, there are a few guidelines you can follow.Location of Temporary Files DirectoryYour temporary files directory should be located on your largest, fastest hard drive (of course :-). A slow hard drive may not be fast enough to record to at higher data rates (like 44.1K, 16 bit, stereo). Also, compressed (or stacked) hard drives require more processor time, and may make recording at higher data rates impossible on slower systems because of the time needed to encode, or compress the data. You want the hard drive with the greatest amount of free space on it as well, since this will limit the size of the file Cool Edit can work with. Be aware that if the wave you are currently working on takes up more than half of the available space on the temporary drive, then you will not be able to save that wave to that temporary drive in a non-compressed format, since the saved file will take up more room than the drive has left. The temporary files directory can be specified in the Settings dialog.Internally, this setting is kept in the TEMPOVERRIDE= line in the [Size] section of COOL.INI. The file COOL.INI is located in your Windows directory. After the section that reads "[Size]" you may enter the line, "TempOverride=D:\TMP" for example.Interrupts and DMA ChannelsMany sound boards use Interrupts and/or DMA channels. For 16-bit audio, you must specify a DMA channel of 5 or greater. Consult your sound board user's guide for more information. For Cool Edit to run at its fullest, these must be set correctly. You can still edit waveforms of any sample type even if your board is not capable of playing them, and even if you do not own a sound card!Some problems occur during recording or playback if the Interrupt or DMA settings for your card conflict with some other installed device (hard drive, network, etc.). Some devices, like SCSI hard drives, may steal too much of the data bus away from the sound card, not allowing it to run at higher data rates. So if you have any problems playing or recording, especially at higher rates (44.1K and/or 16-bit) please check all the settings on all your hardware to ensure there are no conflicts. Cool Edit plays audio directly from the hard drive, so your computer's data bus must be able to handle the traffic coming from the hard drive to memory, and from memory to your sound card at the sample rates you wish to use the program at.Using Cool EditNavigating About the InterfaceThe Toolbar represents the commonly used functions as icons along the top of the window. A quick help description of the button’s purpose will pop up if the mouse remains over the button for about a half second. If too annoying, this feature can be turned off in the Settings dialog.Waveforms are displayed in green.∙Any portion may be selected by clicking on the waveform with the left button, and dragging left or right.∙Holding the SHIFT key while doing so, or using the right mouse button will increase or decrease the size of the currently selected portion.∙Double-Clicking on the waveform will select the entire visible wave.The View Indicator (the green bar above the waveform) depicts which portion of the entire waveform is being viewed in the workspace below.∙Sliding the green bar (when present) left or right scrolls various parts of the waveform below into view accordingly.∙Clicking to the left or right of the green bar will scroll the audio to the left or right one screenful when zoomed.∙Double-Clicking on the View Indicator will bring up the Viewing Range dialog to allow direct entry of starting and ending samples for the portion of the wave to view.The Yellow Arrows indicate the point of insertion. Clicking anywhere in the workspace will move the point of insertion to the mouse.The Red Arrows, when present, represent the Cue List entries for cue markers.The Blue Brackets, when present above and below the waveform represent the Cue List entries for a range.Choose Zoom In to expand the selected portion to the full window. Zoom Out will give a larger view of the waveform, while Full View will display the entire waveform in the workspace.Playing and recording is controlled by the lower row of buttons.∙The Play button will play the portion of the wave that is currently being viewed, or the portion that is highlighted.∙The Pause button will temporarily pause the playback or recording of audio. The button turns into a Continue button when audio is paused. If recording, the red record bar turns yellow to indicate a paused state.∙The Record button will start recording at the current insertion point. Any waveform data after that will be recorded over.∙Use the Stop button to end waveform playback or recording.The Record Level Meter below the Play/Record buttons will display red when a waveform is being recorded, and a real-time display of the input when Monitor Source is chosen. The display turns yellow if recording has been temporarily paused.∙Double-Clicking on the Record Level Meter will start or stop monitoring.The Time Display windows show the current Starting and Ending points of the current selection, or portion being viewed.∙Double-Clicking on these windows will toggle the display between time in seconds, and in samples.The Wave Format window displays the format of the wave in Channels, Sample Rate, and Bits Per Sample.Double-Clicking on this window will bring up the Adjust Sample Rate dialog to change the way Cool Edit interprets samples.A Play Position Indicator (vertical inverse bar) shows the current playing position when a wave is played.The Cool Edit ParadigmThe main purpose of Cool Edit is act as a non real-time studio to edit digital waveforms. Many of the functions take longer than real-time to process, thus there is no non-destructive “playthrough” of any of the effects. So don’t go throwing away your digital effects processors just yet.Only one waveform can be edited at a time, but you are not limited to the number of copies of Cool Edit that can be running. Running multiple instances does not use very much memory, so don’t be afraid to open as many copies of Cool Edit as needed. Instances of Cool Edit can be worked on while others are in the middle of processing audio, since each copy is completely independent of the other. Yet, copying and pasting can be performed seamlessly between each of the instances.When a file is opened, a temporary backup is made, and all edits are made on the temporary backup copy. Changes are only made to the original file if they are explicitly saved back. Choosing File:Re-Open will re-copy the original waveform to the temporary working copy at any time (kind of like a global level Undo). If you are using Cool Edit to just play a waveform, and not edit it, it is better to use some other wave player program, since Cool Edit uses hard drive space to create a backup copy before it can be played.The waveform currently being edited is always resident on the hard drive (except for during the middle of operations). Because of this, waveform sizes are limited only to the amount of free space on the temporary drive. The maximum size Cool Edit allows is just over 1 gigabyte, which should be plenty for most purposes. Because the temporary file takes up hard drive space while Cool Edit is open, you have less space on the temporary hard drive to save your files. Editing a file of more than twice the original free space on the temporary drive will make it impossible to save the waveform on the same drive, unless a compression method is used (e.g. ADPCM).Waveforms are played directly off of the hard drive as well. For this reason, it is important for the temporary hard drive to be as fast as possible. To improve hard drive speed, remove any type of disk compression you may be using if your working on a slow processor system and desire to record at high sample rates. But, waveforms of any size can be played.Keyboard ShortcutsDelete Delete ALT+P Play waveformCTRL+C Copy ALT+S Stop playCTRL+Insert Copy SPACE Play waveform / Stop playing waveform toggleCTRL+X Cut F2 Repeat last command (show dialog if command has one) SHIFT+Delete Cut F3 Repeat last command now (using last used settings)CTRL+V Paste F8 Add the current cursor location or selection to the cue list SHIFT+Insert Paste ALT+M Monitor Source signal toggle on/offCTRL+T Trim ALT+I Waveform InfoALT+Bksp Undo ALT+Z Frequency Analysis WindowCTRL+A Select Entire WaveCTRL+S Select the current viewMouse ShortcutsLeft Click and Drag on waveform to highlight and select a range of samplesRight Click (and drag) on waveform to extend selectionShift+Left Click (and drag) on waveform also to extend selectionDouble-Click on view indicator (green bar) to enter viewing range directly in samples Click to the left or right of green bar to scroll view left or right one screenDouble-Click on Levels Meter (black bar) to start/stop monitoringDouble-Click on Sample type display to change sample type interpretationDouble-Click on time windows to change time formatDouble-Click on title bar to Maximize/RestoreRest mouse over toolbar button to get explanation of button's functionA Short Course in Digital Signal ProcessingSignals (or Waves)Waves in the context of Cool Edit are sound waves. A sound wave can be written as the how the air pressure on your ear changes over time. When you hear a loud sound, the pressure on your eardrum is greater, and it vibrates harder. Soft sounds affect the eardrum very little, and thus are noticed as softersounds. So a wave is a convenient representation of how thesound level varies over a time interval. The illustration is asine wave of a constant pitch. It shows the sound pressureoscillating from low pressure to high pressure and back. Innatural systems, this motion follows the path of a sine wavewhen graphed. The wave here is of a constant frequency andconstant amplitude. Choose any time along the Time axisgoing from left to right, draw a vertical line up and down,and there will be exactly one spot where the wave crossesthis vertical line. This is because a wave can have only onevalue at any instant in time. For example, there can notsimultaneously be two different pressure levels on the eardrum at once. If two sounds are heard at the same time, the pressure levels from both of them are simply added, and a single resultant pressure is observed (and at that instant, it is impossible to tell exactly which role each sound played in creating this single value). So a waveform is depicted as a line that can vary up and down freely, going from left to right, but with no "backtracking" (e.g. a graph of a waveform will never look like a circle, or a "U" on its side).Waves in the natural world are continuous, which means that no matter how much you "zoom in" to the waveform, or no matter how small of a time interval you look at, there are an infinite number of values needed to represent the progression of the waveform during that interval. Other types of waves exist besides just sound waves. Seismic activity can also be viewed as a wave - as in the shock wave during an earthquake. The Richter scale graphs (the familiar graphs of earthquake activity they show on television after a quake) are a prime example. There is a single needle that sways back and forth leaving a mark on a slowly turning cylinder. As the seismic receptors placed into the Earth pick up vibrations, the electrical impulses are sent to the device, causing the needle to sway in response to the movement of the earth.Cool Edit's normal Waveform View displays waveforms just as described, as a plot with the time going from left to right, and at each instant in time there is exactly one value for the waveform's instantaneous amplitude, or pressure level. AmplitudeThe amplitude of a sine wave is the difference between thehighest part of the wave and the lowest part. The differencebetween the high and low pressure parts. A low amplitude,quiet wave would be one that would vary much less up anddown, while a louder waveform would vary much up anddown. Amplitude is generally measured in decibels,although the decibel (dB) itself not an absolute measurementlike Fahrenheit is for temperature, but instead is ameasurement of ratio. If one decibel is the quietest soundsomeone can hear, then the loudest sound one can hearwithout damaging the ears with prolonged exposure wouldbe about 100 dB. Normal speaking would be at about 20 dB.Ten decibels is an increase in volume of 10 times. Thedecibel scale is not linear, but logarithmic, which means that20 dB is not 20 times louder, but instead 100 times louder(10 times louder than a 10 dB increase).FrequencyThe frequency of a wave determines the pitch we perceive, and is measured in cycles per second, or Hertz (Hz). As seen on the graph, the time it takes the wave to complete one cycle is the time it takes to go all the way from the point of lowest pressure, on up to highest pressure, and then back to lowest pressure where it started. A cycle can start anywhere, not just at the bottom of the wave. The cycle will always end at the same pressure level it began. For a male voice, you may count about 180 complete cycles in one second of audio, which would give the speaker's voice a pitch of 180Hz. A female singing voice may attain 600Hz. The key "A" below middle "C" on the piano is about 440Hz. Each time a frequency doubles, it is said to raise an octave. So, if 440Hz is "A" below middle "C", then 220Hz is "A" the next octave lower, and 110Hz is still "A", yet another octave lower. The high pitched ringing you may hear emanating from television sets is around 17,000 Hz. The human ear can perceive frequencies up to about 20,000Hz.PhaseAs a wave cycles through at its particular frequency, it can be thought of as passing through all the degrees of a circle, from zero to 360 degrees. Each part of the cycle can be referred to by its phase, with zero degrees being the midline value as the pressure level is increasing, or as the wave is on its up-swing. Then 90 degrees would be the peak, and 270 degrees the valley. At 180 degrees, the wave is back at the midline, but this time on the down-swing. At any instant in time, a sine wave can have only one phase value. Phase is the one component that human ears can not discern very easily. For example, a bell rang at exactly 12:00pm, we would not be able to notice at exactly one second past 12:00pm whether the phase of the sound we are hearing is at 0 degrees, or 90 degrees, or anywhere. If the bell rang at 3 milliseconds past 12:00pm, the phase at exactly one second past 12:00pm would certainly be different (depending on the pitch of the bell), but we still would not notice it was different.The sounds we hear in everyday life and when we listen to music, are generally not just a pure sine waves as exemplified above, but a collection of an infinite number of sine waves, each at its own varying amplitude, and its own varying phase. At any instant in time, what we truly hear is the sum of all of the frequencies present, each at their own amplitude, and each at a particular phase during their cycle. Summing all these will give exactly one value, or one pressure level that is present at the eardrum at any particular instant. Because of this, a wave can be graphed as the instantaneous amplitude (or pressure level) during an interval of time. Cool Edit's Spectral View will display all the frequencies present at any instant in time (almost), and their amplitudes at that instant. The louder a particular frequency is, the brighter the point will be. The higher up on the display the point is, the higher the frequency is that the point represents. Time is still represented as going from left to right. The reason we say the Spectral View almost displays all frequencies present at any instant in time is because it is impossible to determine all frequencies at any instant that went into producing the pressure level that was measured during recording, but it can be estimated from the audio before and after that point. This is why, as you zoom in more and more, the particular frequencies begin looking very smeared from left to right.SamplingIn the computer, it is impossible to work with an infiniteamount of data, which is what would be required if acontinuous wave were to be represented inside the machine,so at every possible instant in time we would have the valueof the waveform at that instant. For this reason, it isnecessary to sample the data. Sampling consists of breakingup the waveform at constant intervals, and representing allvalues in that interval by a single value. By dividing thewaveform up like this, one second of audio can now berepresented by a finite number of values. The sample rate isthe number of divisions taken per one second of audio. Asyou can see by the graph, the sampled waveform (horizontaldashes) contains much less information about the shape of thewave than the original continuous wave itself. The highestfrequency that can be represented by this method is exactlyone half the sample rate. So, if a sample rate of 22,050 slicesper second was used, the highest frequency that can berepresented would be a tone of 11,025 Hz. This frequency isknown as the Nyquist frequency. The higher the sample rate,the higher the frequencies are that can be represented by sampling. The human ear can hear frequencies up to about 20,000 Hz (or 20 KHz), so to represent all sounds that humans can hear, a sample rate of at least 40,000 Hz must be used, which would yield 40,000 values for the computer for each second of audio. This is why CD players sample at 44,100 Hz, to be enough above twice the highest frequency anyone can hear.So far we have broken time into discrete intervals. What about the actual values, or amplitude, at each of those intervals? The wave above can be thought of as going from values between 100 (at the top) to -100 (at the bottom). This would cause the short sequence of 11 samples to be given to the computer as roughly 93.7, 51.5, -22.1, -89.4, -97.6, -48.0, 25.7, 92.1, 93.9, 54.5, and -21.1. The same problem as with having continuous time exists with the values at each interval as well. There are an infinite number of possible values the wave can have during each of these intervals. For example, instead of the first value being 93.7, it could just as easily have been 93.716746352231... These values must also be broken up into intervals (which may or may not be evenly spaced) so that computers can deal with them. This breaking up of continuous values to a specific number of values is known as quantizing. An 8-bit sound card, for example, can have any one of 256 unique values, where the continuous range of real numbers has been quantized to 256 steps. The reason 8-bit sound has 256 possible values is because 2 to the 8th power (2 x 2 x 2... eight times) is 256. The 16-bit sound cards can have any one of 65,536 values for each interval. The quantization level, directly relates to the dynamic range (difference between the softest and loudest sound) that can be represented (if the range has been evenly divided into equal spaced steps). With only 256 levels, the sound quality is comparable to that of AM radio. With the 65,536 levels possible with 16-bit audio, the quality is comparable to that of compact discs, which can have much louder 'louds', and much softer 'softs'. So, where the sample rate (divisions in time) determines the highest frequency sound that can be represented, the quantization level (divisions in amplitude) determines the highest dynamic range that can be represented. If the divisions in amplitude are not evenly spaced,。

一、降噪处理我们先做一个降噪的实例感觉一下它的功能。

说到降噪有好多种方法,大致上有采样、滤波、噪音门等几种。

这当中效果最好的应该是采样降噪法。

所以我们就先录取一段声音,再给它降噪。

Cool Edit 2000可以录入多种音源包括:话筒、录音机、CD播放机等。

将这些设备与声卡连接好。

然后,将录音电平调到适当位置,就可以准备录音了。

点击菜单File中的New,出现New waveform对话框,选择适当的录音声道(Channels)、分辨率(Resolution)和采样频率(Sample Rate)。

一般使用Stereo、16-bit、44100Hz,这是用于CD音质的设置,效果已经不错了点击Cool Edit 2000主窗口左下部的红色录音按钮,开始录音,并播放CD音源。

完成录音后,点击Cool Edit 2000主窗口左下部的Stop按钮。

Cool Edit 2000窗口中将出现刚录制好的文件波形图。

要播放它,点击Play按钮就可以了。

把波形放大后,将噪音区内波形最平稳且最长的一段选中(一般为没有音乐信号的间隔处)。

然后依次选取菜单里Transform项中的NoiseReduction 命令,就会弹出Noise Reduction的工作界面将界面中Snapshots in profile的参数改为800,FFT Size的数值改为8192,Precision Factor的数值改为10,SmoothingAmount的数值改为10左右,这样可以达到比较好的效果。

改好各参数后,点击Get Profile from Selection按钮,几秒后出现噪音样本的轮廓图关闭窗口,可以听听效果,噪音是不是没有了?不满意就再调调参数,因为音源与录音设备不同,所以需要反复的调试才能达到一个十分满意的效果。

二、自制卡拉OK伴奏带下面一个实例是自制卡拉OK伴奏带。

你是否曾经遇到过自己十分喜欢的歌,但是又找不到卡拉OK伴奏带呢?现在有了Cool Edit 2000帮你,你就不会再为找不到伴奏带而烦恼了!我们可以自制伴奏带。

首先我建议大家安装一个软件,叫豪杰超级音乐工作室。

它不仅可以抓取音轨,还可以互相转换多种格式的音频文件,我们这里需要.wav 格式的文件。

运行数字CD抓轨一项,光驱中的曲目就会显示在菜单上方,挑选你要转的曲目转换即可在Cool Edit 2000中调入转好的文件,选择菜单Transform项中的Amplitude里Channel Mixer项,在弹出的对话框中选择原厂预设参数中的VocalCut一项然后关闭对话框听一下效果,这时你会觉得人声几乎没了,但听一会儿你会发觉似乎缺少了什么。

没错,一些乐器的声音也被消掉了。

那么只有从原曲中抽取这部分内容了(别忘了在下一步之前先把刚才做好的存一下盘)。

将源文件重新打开,选择菜单Filters项中的Graphic Equalizer项(是Cool Edit 2000的插件)。

为了更精确的调节频段,请将视窗切换为30段均衡视窗。

然后调整增益范围,图中正负45dB,中间的10个增益控制基本上就是人声的频率范围。

我们将人声覆盖的频段衰减至最小,边调节,边监听,直到人声几乎没有就可以了按下Switch Mulititrack Mixer View钮,打开CoolEdit Pro的多轨编辑视窗。

将时间指针停在开始处,以便于多轨音频对齐。

在第一轨中按鼠标右键点击Insert项中的Wave from File,选择第1步中处理好的消除人声后的音频文件插入第一轨,再在第二轨中按鼠标右键插入均衡处理后的音频文件插好之后,播放听一下,是不是还可以?不行的话,就分别调大这两轨的音量最后,如果满意了,那么在Edit菜单中选择Mix Down to Track项中的All Waves,将两轨混合输出为另一个文件。

等混音结束后,将它存盘即可使用了不过用这种方法,不可能完全的消除人声,若是完全的消除人声,所付出的也是音乐失真的代价。

不过你在演唱时,你的声音完全可以盖住没消干净的原声,也就没问题了!三、添加音效其实在Cool Edit 2000中最激动人心的功能莫过于可以随意添加音效。

在Cool Edit 2000的菜单Transfrm下,有20个子菜单,通过它们,用户可以方便地制作出各种专业、迷人的声音效果。

如Reverb(余音),可以产生音乐大厅的环境效果;Dynamics Processing(动态处理),可以根据录音电平动态调整输出电平;Time/Pitch(时间/音调),能够在不影响声音质量的情况下,改变乐曲音调或节拍等等。

这些功能就有待你的开发了!音调调整。

在这里,你可以对你的声音做一些润色。

例如,你的音调较低沉,可以提升高音使它更清晰;如果声调偏高,可将它调整的柔和悦耳。

依你所需,选取波形局部或全部,用菜单effect/filters/graphic equalizer打开图示均衡器对话框,如图5。

对话框的标签有三个,分别是10、20、30段的图示均衡器,够专业的吧,任选其一,做适当的调整,单击预览按钮试听效果,可边听边调整。

满意后,单击确定按钮。

注意,为了提高运行与预览的速度,你可以只选一小部分波形来操作。

但是,必须做如下步骤以作用于全部波形:1、按工具栏撤销按钮取消刚才的调整作用;2、选取全部波形,按F2(“重做”的快捷键),按回车。

那么,第“1”步骤的作用是为什么呢?不能对那部分波形做两次处理啊,因此,要撤销它。

除了降噪可勉强做两次,其余效果千万不能这样做。

美化声音。

通过以上的几步,声音已经很清晰了,可你一定觉得还是那样干巴巴的不好听。

在这儿,将是CEP的精华所在。

它居然有超过45种的效果器等着你来选用。

不要太贪心呀,你要是全用上的话,最后效果也不见得多么好,够用就算了。

在菜单effect/delay effect(常用效果器)之下,还有几个子菜单,分别是合唱、延迟、动态延迟、混响、房间混响、回声等。

可选中一部分波形打开相应对话框后,按下预览按钮边试听,边调整。

因为涉及大量专业术语,建议采用预设窗口中提供的现成效果,比你自己调整滑杆要强的多。

这样,用效果器为自己的声音加上恰当的诸如回声、混响等效果。

播放一遍,是不是动听的很。

我已经听到你在偷偷地笑呢。

如English不太好,可借用金山快译等工具来帮忙。

音量量化。

无论进行到哪一步,你发现声音波形过小或是太大,CEP 都提供了顺手的工具。

小比大要好办的多,过大就会造成波形上下两边特别整齐,这表明已经大于0db,形成了“消峰”失真,虽然有工具提供这种消峰现象的修整,但也要尽量地避免。

我们使用音量控制效果器,可以说是CEP中用处最广泛的效果器了。

先选取波形,依次打开effect/amplitude/amplify,打开音量控制对话框,如图3。

从它左上角的两个标签中,可以分别打开constand amplifiction(恒定音量)与fade(渐变)两个对话框,使用方法大同小异,一般的情况下,使用右侧的预置窗口的现成效果就可以了。

我们要调整整个声波的音量,选取右侧的一个预置效果,以分贝(db)为单位的boost(提升)或cut(衰减),可以单击右下侧的预览按钮监听效果,满意后,单击确定。

淡入、淡出的效果与上述相似,选取开头或结尾的约5秒以下的波形片段,再在预置效果里选择fade in(淡入)或fade out(淡出)即可,一般应锁定左右声道。

试听效果后,单击确定按钮。

注意,淡入淡出的效果可千万别反着用上啊,那可太难听了。

波形编辑。

象大多数windows程序一样,CEP对波形的操作也支持删除、剪切、复制、粘贴等操作,且功能更全面、复杂,通过这些操作,你就可以把整个声波处理的毫无瑕疵。

具体操作你可以象在其它程序中一样。

CEP为你提供了相当好用的剪贴板功能,打开edit/set current clipboard(设置当前剪贴板),会发现,它为你增加到六个剪贴板供你使用。

这在编辑文件时就方便的多,特别是重复使用的乐曲或是声响循环,到时,在相应的剪贴板提取就行了。

别忘保存你的文件。

多轨窗口。

在波形上单击鼠标右键,点选insert in multitrack(插入多轨窗口),单击窗口左上角的单轨、多轨切换按钮,切换到多轨窗口,如图1。

你编辑好的波形已在最上面一轨等候了。

CEP的多轨窗口,与premiere、flash、cakewalk等的“时间线窗口”相似,它有一条竖状的亮线,播放时,随着它的移动,作用于经过的所有轨道。

可以用右键向两边拖动某轨的波形,以改变它的“出场”时间。

也可以上下拖动,移至其它轨道。

各个轨道的左边按钮中,有三个较醒目的按钮R、S、M ,分别代表录音状态、独奏、静音,可按照需要选用与取消对此轨道的作用。

三个按钮左侧还有VOL与PAN的选取项,可用直接输入数值或是右击鼠标打开控制推杆的方法,调整该轨的音量或是相位(声音来源的方向,即声相位置)如图1。

按照我们的意图,下面为这首诗加入配乐。

单击左上角的切换按钮回到单轨编辑窗。

单击工具栏新建、打开按钮,在对话框中选择一首合适的音乐,支持WAV、MP3甚至CD音轨等很多格式,在文件类型下拉列表中看看就知道了,可在确定之前,单击play试听此曲。

最让人高兴的是,CEP可以提取视频文件中的配音,不信你看看file/extract audio from video(自视频提取音频),支持AVI、MPEG等。

在打开的乐曲波形上右击鼠标,点选insert in multitrack ,将它插入多轨窗口。

如果需要,当然可以在这之前进行诸多的效果处理。

插入到多轨的波形将被自动放置在空缺的最上面一个轨道。

多轨混音。

进行到这儿,多轨窗中,应该有两轨波形,第一轨是你读的那首诗,第二轨是配乐。

按住鼠标右键左右拖动某轨波形,将它的“出场”时间调整合适。

下面要做的我觉得应该是调整两轨的音量比例了。

它们之间,既不能喧宾夺主,也不能唯我独尊。

对某轨做整体的调整可能过于片面。

这样,我们让音乐开始时照常,你的声音出现前,乐曲渐弱至一恒定音量,等到诗歌读罢,乐曲音量回到正常。

依次选取view/enable envelope editing(允许包络线编辑),并且在show volume envelopes(显示音量包络)之前勾选,如需要,还可勾选show pan envelopes(显示相位包络)。

在每条音轨的上部将出现亮绿色的音量控制包络线,和位于中间的亮蓝色的相位控制包络线(当然,这些颜色可以自定义),如图7。

用鼠标可对各个轨道声波的局部或者全部,进行音量与相位(声音在左右声道间的位置)的控制。

我们单击第二轨任一空白处而选中此轨,在朗读声相应部位的音量控制线上,单击鼠标加入控制点,上下拖动控制点,以减弱音量,音量百分比同时会显示出来。
