The advantage of having a physical mixer is also that it will always be possible to broadcast even if

the central computer breaks down – which it will do occasionally!

Once the sound files are inside the computer, one will need editing software to process the

recordings. There are several different brands, and some are designed primarily for stand-alone

computers, while other programmes are more suitable for networking several workstations in a

bigger radio station. But all programmes have the common feature that it is possible to work with

sound and sound bytes exactly the way that one can work with text in a word processing software. It

is possible to select words or even parts of a word and move it around, make the sound louder or

softer, and one can play recordings faster or slower. And naturally one can combine several

different recordings. When the Beatles recorded their first songs it was done on a four-track

recorder – today any standard computer can be turned into an 80-track recorder if that is what you

need.

All editing programmes have a graphic user interface, which enables the producer to physically see

how loud a sound is, and it is possible to see where a word starts or ends, so sound editing on a

computer is quite easy to learn. The difficult part of computer editing is the basic knowledge about

computers. If you have never operated a computer mouse or saved, copied or moved a file, it can be

quite a job to start working on a computer – but the actual editing process is astonishingly simple.

Even illiterate persons can learn the editing skills very fast.

As mentioned above, one can use practically any sources to gather the sound. Although the sound

processing is digital, the recording do not have to be digital. One can easily use sound from a

cassette recorder – but the quality is not as good as in the new digital recorders.

The digital Mini Disc (MD) player/recorders were actually designed for the mass consumer market,

but they never caught on like the CD. But they did change the possibilities of the broadcasting

industry because the MD’s proved excellent for radio production. The recorders are small and

handy and the sound quality is superb. Furthermore, the actual discs can be used for recordings

hundreds of times without loosing quality, and an experienced user can even edit interviews and

other recordings directly on the MD.
