One of the programs is a decoder for DAB(+) signals. This summer I wanted to learn Ada (again, after a period of well over 20 years) and I made a reimplementation of the DAB software in Ada. The resulting Ada program is limited compared to the C++ one in that it is not possible to change dynamically device and DAB mode, and the GUI - I used GtkAda - is pretty limited. It does work however fine. Supported input devices are the common dabsticks, the SDRplay device and the airspy.Output is currently using a "default" outputchannel on the PC. I would like to get some feedback on the use of the Ada language. I am using bindings to C (some libraries are in C), callbacks from C libraries and quite some tasking. The sources are available on github: you can download them by git clone https://github.com/JvanKatwijk/ada-dab. Any feedback and suggestions for improvement (it definitely runs slower than the C++ version) is welcome Thanks jan
