Audacity Editing existing files

The Birth of Radio Radio was invented at the end of the 19 th Century by Guglielmo Marconiinvented At first, it was used to send morse code without using wires. Later, speech and other sounds were carried using the new technology. In the 1920’s, Radio broadcasting was born.

Broadcasting Presenters and performers would assemble in a studio and make a live broadcast. Powerful transmitters sent out radio waves representing the sound. These radio signals could be picked up by anyone within range with the right receiving equipment. The same basic technology is still in operation today.

Internet Radio In recent years, a new form of Radio broadcast over the Internet has arisen. It has the advantage that you can pick up stations from anywhere in the world. The expensive transmission equipment necessary to make normal radio broadcasts is not required, so virtually anyone can start an Internet radio station.

What we’re doing You COULD create your own radio station! Over the next few lessons we will learn how to edit existing content. We will use a program called Audacity to record and edit the content.
