Using Cool Edit 96

Cool Edit 96, produced by Syntrillium Software Corporation, comes in two versions. Cool Edit Pro has all featured enabled for use at any time. The cost is $399.00. If you plan to edit lots of audio for your course, it might be worth it to purchase the fully enabled version.

Syntrillium also has a shareware version, called Cool Edit 96. If you choose not to register it, you can only use two features per session. If you register for $50.00 you can use all features. Registering for $25.00 allows you to use most, but not all features.

To experiment with, the unregistered version will work just fine.

This is only a brief introduction to this complex and sophisticated program. To use its features fully, some knowledge of sound is required. The Help menu can help you learn more about sound.

From the Start menu, select Programs, then select Syntrillium, then select Cool Edit 96.

From the dialog box that asks which two functions you would like to use in the unregistered version click OK to select the default options.

The Cool Edit 96 program opens.

From the File menu, select Open and open the .wav file you have recorded. Or, open the audio1.wav file on the diskette for this workshop. A visual pattern (waveform) of the sound file appears.

Click the Play button in the lower left hand corner. Notice that a white line begins to move from the left side to indicate how far along in the file you have played. Clicking Stop moves the white line back to the beginning of the file. Clicking Pause stops playing temporarily. Click Continue to continue playing.

The image above shows a .wav file that was recorded in stereo. Notice that there are two different waveforms, one above the other. For files that are monaural, there would be only one waveform.

The boxes in the lower right corner provide information about your file and how it was produced.

In the example above, the file was recorded as a 16 bit stereo file. It contains 645645 samples. The more samples in an audio file, the closer the file comes to the actual sounds that were made when the file was recorded. the more samples, the larger the file and the longer it will take to download.

The Time box gives the length of the file in minutes and seconds.

Deleting Part of a Sound File

Editing sound files for use in a course often involves removing unwanted sections, such as sections that contain "dead space" at the beginning or the end. Cool Edit 96 does this very easily.

First, use the Play button to identify the part you want to delete. Use the Zoom, In and Out buttons to zoom in on the part of the audio you want to edit out. The green/black bar at the top of the waveform acts as a slider so that you can find the section of audio you are interested in.

When you have identified the part you wish to remove, click and hold down the left mouse button. Drag it to the right or left to select a portion of the waveform. From the Edit menu, select Cut, or use the keyboard shortcut, Ctrl X.

If you find you have made a mistake, from the Edit menu, click Paste. Note that you can use a similar procedure to move a piece of audio. After cutting, find the place you want to insert the clip, select it with your mouse, and from the Edit menu, select Paste.

Resampling Audio

Sometimes audio is initially recorded at settings that produce a high quality audio file that is too large to use. By resampling, the file can be made smaller (and poorer quality).

Click and drag your mouse to select all or a portion of a file that you have opened in Cool Edit 96. From the Edit menu, select Copy.

From the File menu, select New Instance. A new empty Cool Edit window opens.

From the File menu of the new empty window, select New.... A dialog box opens asking for the sampling information and other characteristics of the file.

Select the options you want and click OK.

Saving a File

From the File menu, select Save As. The save file dialog box opens allowing you to choose a number of options including file name and location. At this time, you can also save the file in the audio format of your choice. Save the file to the Desktop.

Click the Save as type dropdown arrow to see the filetypes available to you. If you are planning on using the file on a Real Media server, select RealAudio, .ra.

Close Cool Edit 96. From the Start menu, select Windows Explorer. Find the Desktop and double click the .ra file that you saved. It should open and play in the Real Player.
