Definitions of digital audio broadcast:

• the TLA for wireless digital radio services, also known as IBOC/DAB. DAB is terrestrial radio in that it's local or location-based, as opposed to national digital satellite “radio.” IBOC, or in-band on-channel, means that DAB shoehorns a digital stream into the existing AM and FM analog services, maintaining backward compatibility. DAB employs lossy codecs to reduce the transmitted data rate.

• Digital audio broadcasting or DAB is a developing technology for broadcasting audio programming in digital form. Broadcast radio has been in widespread use since the 1920s, and to this time has remained largely based on the analog "amplitude modulation" (AM) technologies used at the beginning and the "frequency modulation" (FM) technologies introduced in the mid-20th Century. The objective of converting to digital systems is to enable higher fidelity, greater noise immunity, and new services.
