DAB+ is a digital radio broadcasting technology that offers improved sound quality and more efficient use of the radio spectrum compared to traditional analog radio. It allows multiple radio stations to transmit their signals on a single frequency, providing listeners with a wider variety of channels without interference. The "plus" in DAB+ refers to enhancements over the original DAB system, including better audio compression and error correction. This means that listeners can enjoy clearer sound and a more reliable signal, even in areas with weak reception. Many countries are adopting DAB+ as a standard for digital radio broadcasting.
