Digital Audio Broadcasting Plus
DAB+ is the acronym for Digital Audio Broadcasting Plus.
An enhanced version of the original DAB standard, which was developed to provide better audio quality and more efficient use of radio spectrum compared to traditional analog radio broadcasting systems, such as AM and FM.
DAB+ uses a more advanced audio codec called HE-AAC (High-Efficiency Advanced Audio Coding) in comparison to the original DAB’s MP2 codec. The HE-AAC codec allows for better audio quality at lower bit rates, resulting in more efficient use of bandwidth and the ability to accommodate a larger number of stations within the same frequency band.
Some advantages of DAB+ over traditional analog radio broadcasting include:
- Improved audio quality: DAB+ provides better audio quality with less noise and interference compared to analog radio systems.
- More stations: DAB+ allows for a higher number of radio stations to be broadcast within the same frequency band, providing listeners with a greater variety of content.
- Data services: DAB+ enables the transmission of additional data services alongside audio content, such as station information, traffic updates, and song information.
- Better reception: DAB+ offers more robust signal reception in challenging environments, such as urban areas with tall buildings or hilly terrain.
DAB+ is currently being adopted in many countries around the world as a replacement for, or in addition to, traditional analog radio broadcasting systems.
