8 The DAB function
8.1 What is DAB+?
DAB+ is a new digital format through which crystal clear sound with no noise can be heard. Contrary to conventional analogue
radio transmiers, in the case of DAB several stations are transmied 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. Information is available on e.g. www.dabplus.de or www.dabplus.ch.
8.1.1 Data compression
With this, 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, for every unit of information the relevant relative volume for other
units is saved. Moreover, in an audio signal, the quieter parts are superimposed by louder ones at a specific limit value. All audio
information in a piece of music that is below the so-called listening threshold can be filtered out of the transmied signal. This
leads to data reduction in the data stream being transmied, with no perceptible dierence in sound for the listener (HE AAC v2
process as a supplementary codification process for DAB+).
