Radio began with scratchy mono recordings that were transmitted on AM frequencies. Then a revolution occurred, and suddenly there was FM, with its clear stereo sound. Now its time for a new technology to revolutionise the way that we listen to music and catch our favourite radio programs - its DAB, or Digital Audio Broadcasting.
"DAB boasts a much superior sound quality than that of the conventional services. It also does not suffer like analogue services from noise sources such as power lines or other radio stations (adjacent channel interference). This means that the quality of transmission can be chosen between near CD quality stereo (256 kbps) right down to low bitrate mono transmission (less than 100 kbps)."
What is DAB, and how does it work? Read on over here.
