unit 11 readingCool Edit Guide1. IntroductionCool Edit is a sound manipulation program that allows you to open, create or record new sound files and edit them. You can use Cool Edit to record your own music, voice or other audio, edit it, mix it with other audio or musical parts, touch it up, and add effects.This guide gives you a concise introduction to Cool Edit's basic features and sound editing capabilities. For more assistance in working with sound files, such as mixing or publishing sound on the web, refer to the Electronic Resource Center's Audio Resource page, or consult the DMC staff.2. Basic Navigation in Cool EditCool Edit is designed for user-friendliness while containing a variety of different features for sound editing. There are several basic components that you will be using in Cool Edit:2.1 Waveform DisplayThis is the main window where your audio files are displayed for editing. Your audio appears in the shape of a waveform.2.2 Display Range BarThis indicates which part of the entire waveform is currently being viewed in the waveform display. When you zoom in on your waveform, the bar will become smaller in size, as you are viewing a smaller portion of your entire audio file.2.3 Transport ToolbarThis is where you access basic audio functions in Cool Edit. They are as follows:stop go to beginningplay rewindpause fast forwardplay to end go to endplay looped record2.4 Time and Amplitude RulersThe time ruler is on the bottom of the waveform display. The amplitude (intensity) ruler is to the right of the waveform display.2.5 Zoom ControlsThe zoom controls allow you zoom in either horizontally (magnifies time) or vertically (magnifies amplitude) with respect to your waveform.Time Display FieldsThese are useful when selecting and splicing audio. The Sel time display fields show the time at which your selection begins and ends as well as the total time of the selection. The View time fields show the beginning, ending, and total time of the part of the waveform currently in the Waveform Display.3. Working with Audio FilesTo record a new file:•elect New from the File menu•The New Waveform dialog box will appear, prompting you for a sample rate, channel, and bit resolution. If you are unsure of what to use, choose 44100, stereo, and 16-bit. These are the settings for CD-quality audio, which is roughly capable of producing the full range of human hearing. However, always choose files based on your needs for size and quality. Stereo files (left and right channels) take up twice the space of mono files.•To begin recording, set up your recording materials, such as inserting a CD into the CDdrive or preparing your microphone. See the PC Audio helpsheet for more specific information about making connections to the computer.•Hit the Record button•Start whatever audio it is you want to record. For example, click on Play in Cool Edit's CD player controls , or begin speaking into your microphone, etc.•When you have finished recording, press Stop . Your waveform is now ready forediting.To open an existing audio file:•Go to File > Open•Choose your file by browsing and selecting your desired file. Supported audio formats for Cool Edit are as follows:.WA V, .AU, .MP3, .PCM, .RM, .IFF, .SVX, .AIF, .SND, .TXT, .VOX, .DWD, .VOC•Click Open. Your selected audio file will be displayed in the waveform display.Using the Undo feature:•Cool Edit retains backup copies of your sound file as you edit so you can undo each edit that you perform. This enables you to travel back to previous states of the audio file, without having to worry about destroying the original audio file.•To use the undo feature, just go to the Edit menu and select Undo.To remove multiple edits, click on Undo again. Your edits are not finalized until you save and close the audio file.4. Making SelectionsSelecting is the essential tool you will be using in order to edit your sound files.For basic selection:•Place the cursor at the point in your waveform where you would like to begin the selection and then left-click and drag to the right to highlight your selection.•Hold down the right mouse button and drag to either side to extend your selection.•To adjust your selection by single pixels, use the right and left arrow keys.•You can also make a selection by double clicking on the Sel Time Display Fields and entering values for time.Fine-Tuning your Selection:•Use the zoom tools to magnify the waveform display. From here you havegreater control over what specific audio is selected.Zero Crossing adjusts the beginning and end points of a selection to the nearest place where the waveform crosses the center line. This makes for seamless transitions when cutting and pasting. The zero crossing commands are found under Edit > Zero Crossings.Find Beats, also under the Edit menu, allows you to define a selection based on the boundaries of musical beats.5. Editing SoundTo cut, copy and paste sound:•Use the Edit menu or the toolbar to Cut, Copy and Paste selections ofsound.•You can use multiple clipboards for greater versatility in working with your selections by using Set Current Clipboard.•The Mix Paste command mixes the audio data on the clipboard starting at theinsertion point. This allows for smoother transitions into the audio file. You can experiment with the settings in the Mix Paste dialog box to find the best option for your needs.To delete or insert silence:•Silence is defined as any audio below a given threshold for a given time period.•To delete silence in an audio file, select part or all of your waveform. Then go to Edit > Delete Silence to define your thresholds. Click OK to delete the silence.•To convert a selection to silence, select the part of the waveform you would like to silence and go to Transform > Silence.•To add silence to an audio files, select your insertion point, then choose Generate > Silence and set a time. This will increase the total time of your audio file.Special EffectsYou can add special effects to selections of audio by using the Transform menu. Here are a few options you might find useful:•Amplitude changes the volume of sound at different points in your audio file.•Delay Effects adds effects like echo, reverb, and flanger to simulate an acoustic space for your sound.•Noise Reduction reduces unwanted background noise such as tape hiss or microphone background noise.•Special > Brainwave Synchronizer can produce stereo files that will put the listener into any desired state of awareness.6. Exporting your SoundWhen exporting to MP3, real audio, or any other file format:•When you have finished editing, go to File > Save As.•Specify the file format you wish to save as in the Save as Type field.•Click Save.Your sound is now ready to be published or archived.New Words11 user-friendliness n. 用户亲善/友好11 touch up vt. 润色；提高Phrases〖BT3〗〖WTHZ〗Exercise to the Passage for Reading〖STHZ〗〖WTHZ〗［Ex 5］〖WTBX〗〖ST〗〓Decide whether the following statements are true (T) or false (F) in relation to the information in the passage. 〖WTBZ〗1.
