Production facilities

   There are two different ways a radio commercial can be produced the first way is through a commercial radio company such as Key 103, smooth and capital who has their own production studios for clients. They'll also be able to produce commercials independently.  Independent companies such as http://www.radioproductioncompany.co.uk/studio.html make ads for clients. They must have facilities such as sound proof voice recording booth, a mixing desk and an editing workstation/s that has editing software like Audacity, reaper, adobe audition or something similar to these. 

Sound proof voice recording booths can stop the sounds of instruments, vocals and other equipment getting outside. When in one of these you'll find if you sing loudly or play an instrument with the doors and windows closed you will not be heard outside of that room or you will sound very distant. They use these so no background noises like phone calls, conversations and other noises aren't in the recording. 

Both will also need a mixing board in order of them to be produced professionally, these are used to mix, route and change the level timbre or dynamic of audio signals. They can mix a variety of things such as analog and music. 
The last thing they must have is at least one working station which has editing software like Audacity, reaper, adobe audition or some other similar to these to achieve the commercial at professional standards. 'Reaper is digital audio workstation software: a complete multitrack audio and MIDI recording, editing, processing, mixing and mastering environment.' I've used this editing software at college when producing 3 different radio news stories.

We haven't used Audacity editing software in college for any projects.

'Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. The interface is translated into many languages. You can use Audacity to: 

1.  Record live audio.                                                                                                                              
2. Record computer playback on any Windows Vista or later machine.                                                          
3. Convert tapes and records into digital recording or CDs.                                                                          
4. Edit WAV, AIFF, FLAC, MP2, or Ogg Vorbis sound files.                                                                             
5. Cut, copy,splice or mix sounds together.                                                                                               
6. Change the speed or pitch of a recording.'                                                                                            

 I also haven't used Adobe Audition in college for any projects, it erases, repairs and creates sound with powerful new features and seamless integration across tools. Some of the new tools are:

1. Sound remover                                                                                                                                
2. Preview editor                                                                                                                                   
3. Enhanced multitrack editing                                                                                                                
4. Advanced sound design                                                                                                                      
5. Roundtrip editing workflow

7. Enhanced spectral display
