Digital Radio Mondiale (DRM) is the new standard for digital terrestrial broadcasting in the existing long, medium/AM and short wave bands. The transition from analog to DRM digital broadcasting is the ultimate way to revitalize these broadcast bands by eliminating the main reason for their decreasing popularity: the inferior audio quality compared to analog FM, and new digital satellite and Internet radio services. Enabled by Coding Technologies' highly efficient aacPlus audio compression scheme, DRM provides FM-like audio quality, formerly unknown in the bandwidth restrained AM channels.

Standardized by the International Telecommunications Union (ITU), the International Electrotechnical Committee (IEC), and the European Telecommunications Standards Institute (ETSI), the DRM broadcasting system is the only open standard for digital broadcasting in the AM bands. The DRM consortium, founded 1998, today comprises nearly 100 members including world's leading international broadcasters, manufacturers, network operators, researchers and regulatory bodies. In June 2003, only five years after its foundation, the DRM consortium officially launched Digital Radio Mondiale with nearly all international broadcasters providing DRM services, and the first receivers available from Coding Technologies.

As the leading provider of audio encoders and decoders for Digital Radio Mondiale, Coding Technologies offers state-of-the-art solutions to facilitate DRM transmitter applications and DRM radio receivers.
