From the developer:
SDRadio is only a subset of the above definition, dealing only with the receiver part, and the ADC is not exactly wideband, but it is what is offered by the majority of today's sound cards, i.e. either 48 or 96 kHz. Nevertheless it can be considered as a first step in that direction.
A software radio is a radio whose channel modulation waveforms are defined in software.
