What is DAB (digital audio broadcasting)?

Digital audio broadcasting (DAB) is an advanced radio standard for broadcasting digital audio radio administrations in numerous nations, characterized by the WorldDAB forum. The DAB standard was a European research project called Eureka-147 in the 1980s.
DAB is more efficient in its utilization of spectrum than analog FM radio and thus can provide more radio frameworks for the similarly provided bandwidth. DAB provides compact disc-quality audio on the frequency modulation broadcast band and provides FM-quality audio on the amplitude modulation broadcast band.
