8.1 DAB / DAB+ radio

8.1.1

What is DAB?

DAB is a new digital format that delivers crystal-clear sound in CD quality. So even if you're
in the car or on the train, you can still enjoy good, noiseless reception. DAB broadcast uses a
high-speed datastream in the radio channel. Contrary to conventional analog radio transmitters,
in the case of DAB, multiple stations are transmitted on one and the same frequency. This is
referred to as an ensemble or multiplex. An ensemble is comprised of the radio station as well
as several service components or data services which are broadcast individually by the radio
stations.

Data compression
By doing so, digital radio takes advantage of the properties of human hearing. The human ear
does not perceive sounds which are found under a specific minimum volume. Data which are
found under the so-called audibility threshold can, therefore, be filtered out. This is possible
because, in a digital data stream, the relevant relative volume for other units is saved for every
unit of information. Moreover, in an audio signal, the quieter parts are superimposed by louder
ones at a specific limit value. All the sound information below the threshold of hearing in a piece
of music can be filtered out of the signal to be broadcast. This reduces the size of the datastream
to be broadcast without a perceptible difference in sound for the listener (MUSICAM procedure)
