Digital Audio Broadcasting

Digital Audio Broadcasting (DAB) is a digital radio standard for broadcasting digital audio radio services in many countries around the world, defined, supported, marketed and promoted by the WorldDAB organization. The standard is dominant in Europe and is also used in Australia, and in parts of Africa and as of 2025, 55 countries are actively running DAB broadcasts as an alternative platform to analogue FM. DAB was the result of a European research project and was first publicly released in 1995, with consumer-grade DAB receivers appearing around the late 1990s.
