Description: a DRM (Digital Radio Mondiale) and AM Software Defined Radio Digital Radio Mondiale (DRM) is the digital radio standard for the long-, medium- and short-wave ranges. The standard was formed by a consortium in co-operation with the International Telecommunication Union (ITU).  For more information visit www.drm.org.  Dream uses the sound card as the input and output device. A long, medium and short wave front-end with an intermediate frequency (IF) between 5 kHz and 15 kHz is used to receive the DRM signal. Any commercial front-end with an IF of 455 kHz should be usable by adding a 455 kHz to 12 kHz adaptor (assuming the receiver bandwidth is sufficient for a DRM signal).

The Dream software development was started at Darmstadt University of Technology at the Institute of Communication Technology by Volker Fischer and Alexander Kurpiers in 2001-2005. The core digital signal processing and most of the GUI were the result of this development.

Dream creates an ini file in the directory it is run from. Sub folders for AFS, EPG and MOT files are also created.
