Open digital broadcasting techniques based on software defined radio. Digital radio transmission and development must also become democratized for experimenters and small broadcasters. Opendigitalradio.org wiki is about creating a community for documenting and exchanging experimentations and gather information about existing small-scale DAB projects. Please read [[Introduction]] for more information.
'''[[Association Opendigitalradio|Opendigitalradio is a non-profit association based in Switzerland]]''' (page in french), offering also a broadcast infrastructure for temporary radio stations.
This wiki is also the home of the '''ODR-mmbTools''', the continuation of the CRC-mmbTools from [http://mmbtools.crc.ca CRC]. Please see [[Introduction on DAB/DAB+]]
Have a look at the [http://opendigitalradio.github.io/mmbtools-doc/mmbtools.pdf guide]

The ODR-mmbTools are used in several real-world 24/7 broadcasts, as shown on http://www.opendigitalradio.org/software
A recipe for a low cost DAB transmission chain for local broadcasts based on the ODR-mmbTools is the [[RaspDAB]] description.
