How to.....

I had never made a radio broadcast before! However i am fully trained to use the radio equipment at out school and even train other users.
But i looked on the Internet to find quick guides which would help me know what sort of aspects i need to cover when producing my preliminary task. The main programme to edit any recording let alone a radio piece is Audacity and more specifically Version 3 as it was the newly upgraded and most recent version.
However having previously produced a sub standard piece of media i was furious at myself and vowed that this broadcast will be better.

How to Use Audacity

Audacity is a simple sound editing program that can be downloaded for free of the Internet. While it is fairly easy to use some people may found it difficult to get started so here are some instructions on creating a simple project:

Steps
1. Plug in your microphone and headphones or ensure your speakers are turned up.

2. Make sure "microphone" is selected in the top right hand corner.

3. Click on the red circle which will start recording and speak into your microphone. If it doesn't look like anything is recording make sure that you increase the dial next to the microphone icon. Your voice will appear as a long jagged line but it may look more like a series of blue shapes.

4. Adjust this to make the microphone more or less sensitive to your voice

5. Place your cursor at the beginning of the audio, click and drag towards to right to select all of the sound.

6. Go to "Effect" then Amplify to adjust the amplitude of your sound (i.e. loudness). If you click OK without adjusting anything then it will automatically make your sound as loud as possible before clipping occurs (where some sound is cut off and it will lose quality). You may not want it this loud though so you can adjust it to any volume. Setting it to a negative number will make it quieter.

7. Import some background music by going to project then Import audio and double clicking on selected music.

8. Edit the background to desired amplitude (See step 5)

9. (Optional) Select the part of the background music you want to have under your voice as it will likely be too long. Leave some extra to fade in and out. Then click the button shown in the image that will trim the out side selection.

10. Select the icon for the 'time shift tool" (double headed arrow) which will allow you to move round your sound. Align your voice with the background music.

11. Click back on the 'Selection Tool' (looks like an I).

12. Select a small section at the beginning of your background music.

13. Select a small section at the end and then go to Effect then Fade out.

14. Experiment with other effects on the music and your voice. Continue with the steps when you are happy with what your have produced.

15. Go to file then save project as to save your work. Type in a file name and click save. This is the version you will open in order to edit your project if you wish.

16. Go to file then Export... or Export as Mp3 (Depending on the version of audacity) and save similarly to the previous step. This is a compressed version you can use on websites or other applications.


I used Audacity to edit and export all my audio pieces for the broadcast and learned new and different skills in order to give a professional and neat edited piece of media.
For example i had to amplify pieces of audio up and down to make sure they were at similar levels and also wouldn't be too loud.
