edit audio

First, you'll need to read the post about Audacity audio editing software:

Once you're pretty sure you've downloaded the program into your computer, and that you THINK it might work, you can find free sounds to edit at the FreeSound Project here:

You should probably build a folder in your computer for SFX. That's shorthand for "Sound Effects." You can download a few sound files there.

Now, go back to your Audacity program. Open one of those sound files. Read the Audacity tutorial. The Transom.org tutorial can be a big help, and Audacity has help & tutorials, too.

Try cutting the soud file up. Maybe you can put a 2nd sound file on another track.

Follow the instructions on how to save the file. Again, you might want to create a special folder for your audio work. You can call it, "Radio" or "Audio," etc. Imagine the future. You'll want to create seperate folders for each radio piece you'll make. It's easier to keep individual sound files seperated into folders, within folders. That way, you won't be hunting all over your computer to find the sounds you've downloaded and saved.

Practice. Just practice.
