There is still the kilo-buck up front to deal with.

i do not know if and how jan licensed his soft ...

if you would have to pay 1 euro per user ... then the user should pay it (or it will be a very expensive hobby for you hi hi)

means you build your soft without the dab decoder and if a user wants that dab decode he can buy a plugin for a euro?!?!

i do not know if it is possible to "split" that in half (means give your sdr console for free but have a paid plugin)

But,

 

Software like this needs an AAC licence even if it’s free. I think I will have to pay $1,000 one-off, then 98 cents per user to add AAC.

look for qt dab ... soft from jan

https://github.com/JvanKatwijk/qt-dab

lots of hardware included (rtl dongle, sdrplay, lime, pluto etc etc) ... he even works on receive via dab and retransmit on analog fm stereo (if you use a pluto) ... then you can receive your favourite dab station on any normal fm radio in your house (retransmitting not finished yet)

jan is now on holiday but will be back in a few weeks (mid of july?!?)

Welle.io is not bad but uses a lot of CPU and I don’t think it drives my Airspy R2 correctly.

It depends. If it is built to use FFTW, then yes. The CPU-load in my case is around 17%.
But if I build Welle-IO using Kiss-FFT and compiled using fast-calls (option -Gr), then the CPU drops to only 10%.

Edit: the Airspy problem is proably related to how Welle-IO handles SoapySDR. Not very good IMHO.
