Qt-DAB-6.9 differs in details from the previous version, most of them are deep inside the software.
A few observations though
a. a new implementation of a viterbi decoder is installed, and made default in constructing an executable. The implementation is parameterized on the cpu support for either none, SSE4 or AVX2 instructions. The software will dynamically select the support value
b. merely as a gadget, clicking on any of the widgets {main widget, configuration and control widget, spectrum widget} instructs the software to generate a picture of the widget involvded. The picture is stored in the Qt-DAB-files filder.
The transition to Qt6 seems complete, therefore in this release only the Qt6 based versions are shown
