Capturing Audio

 

 

 

Prerequesites for Capturing Audio

Some people have a professional recording team record their lectures or sound clips, but most of us record our own. This is a brief guide for those who do it themselves.

You need a sound card installed in your computer, a microphone to record sound, and speakers to hear how it sounds.

These instructions are for those people using Windows95, 98 or NT and describe the use of the Sound Recorder that is built into Windows. You may have more sophisticated software installed with your sound card. Refer to the documentation or help files that came with your computer hardware.

The general steps are illustrated below.


Recording

From the Start menu, select Programs, then Accessories, Multimedia, then Sound Recorder.

Click on the Begin Record button (with the red dot) and start speaking into the microphone. You can see the pattern of the sounds as the green line changes to reflect the intensity of your voice.


Saving the File

When you have finished, click on the Stop button. From the File menu, select Save As... Name your file with the extension .wav.

Before you click OK to save the file you have the opportunity to change the Format and Attributes of the file. You may wish to experiment, but changing the Attributes may also increase the size of the file. For your students' comfort, the file should be as small as possible.

Click on the Play button to hear your sound file as you recorded it.


Optimizing and Editing the Audio

Now you have a .wav file of your voice. You can use an audio editor to edit and optimize your file. Some instructions for using the audio editor CoolEdit 96 are given below. You can download and use a shareware copy of CoolEdit 96.
