What is Digital Audio Broadcasting?
Digital radio, commonly known as DAB+, offers significantly better sound quality compared to traditional AM radio. Unlike AM or FM radio, it is not affected by interference or static, ensuring a clearer and more consistent listening experience.
Tuning into stations is also much simpler. Instead of manually adjusting frequencies, you can easily choose your favorite ABC radio station from a convenient alphabetical station list on your device.
Additionally, many digital radios provide helpful on-screen information, such as the current song title and artist, as well as news headlines, weather reports, and traffic updates, enhancing the overall listening experience.
DAB+ coverage is available throughout all major Australian capital cities, as well as in regions like the Gold Coast and Launceston.
History of Digital Audio Broadcasting
Digital Audio Broadcasting (DAB) started as a European research project called Eureka-147 in the 1980s. The Norwegian Broadcasting Company (NRK) launched the world’s first DAB channel, NRK Klassisk, on 1 June 1995. The BBC and Swedish Radio (SR) followed suit by launching their first DAB broadcasts at the end of the same year.
Since the late 1990s, DAB receivers have been available in many countries. Initially, DAB used the MP2 audio codec. However, a more advanced version of this system was released in February 2007 under the name DAB+, which uses the more efficient and powerful HE-AAC v2 (AAC+) audio codec. It should be noted that DAB is not compatible with DAB+, so older DAB receivers cannot receive DAB+ broadcasts.
