Digital Audio Broadcasting, known as DAB+ in Australia, is found in many Asian and European countries as DAB. Digital broadcasting allows you to receive radio as a digital stream, decoding it into a format capable of superior audio quality. Most Australian government funded and large commercial stations have a DAB+ option and a large array of digital-only stations are popping up. DAB+ is the upgraded standard of DAB, allowing for use of the AAC+ codec. It is available and very effective in all Australian major cities but is rarely effective in rural areas. If you live outside of the city, we would recommending avoiding DAB+.
