Digital Audio Broadcasting (DAB), also known as Eureka 147, is a technology for broadcasting of audio using digital radio transmission. The original objectives of converting to digital transmission were to enable higher fidelity, more stations and more resistance to noise, co-channel interference and multipath than in analogue FM radio. However, in the UK, Denmark, Norway and Switzerland, which are the leading countries with regard to implementing DAB, the vast majority of stereo radio stations on DAB have a lower sound-quality than FM due to the bit rate levels used on DAB being too low. This assumes that the listener has good reception on both DAB and FM, however, but FM can suffer from fading caused by multipath when the receiver is travelling at high speed which DAB is less prone to. For stationary reception, FM can suffer from hiss when the signal is weak, whereas DAB produces a "bubbling mud" sound when the received signal is too weak for proper decoding.

Digital radio describes radio technologies which carry information as a digital signal. The topic covers both broadcasting by radio and two-way communications. The acronym DAB has been used to identify the generic technology of digital audio broadcasting, although now it has become synonymous with the Eureka 147 standard.
