Step For Using Audio Visual

STEP FOR USING AUDIO VISUAL IN CLASSROOM

Step 1
Read your program's instructions. This will give you an idea about what kind of computer and audio equipment you should use. It will also take you through a step-by-step process to help you use your audio program.

Step 2
Load your sound into your computer. Open your audio program and find an option in your tool bar that allows you to record. Start recording before you speak into a microphone, start a cassette or load a CD.

Step 3
Identify changes in your sound file. Your sound will appear like a line graph across your screen. The parts of the line that are horizontal are whispers or dead air. The parts that look like mountains are parts of actual words or sounds you recorded.

Step 4
Eliminate the dead space by dragging a cursor across a horizontal line in your sound. Press deletes to get rid of it.

Step 5
Rearrange parts of your sound by using cut, copy and paste options on your computer. Highlight the part you want to copy or cut. Then place the cursor where you want the sound to reappear.
