I think it is still a two step process until it is added to ld-decode. There is FPGA code in staffanu's repo which opens the door to new AC-3 RF demodulators or modding players to output the demodulated signal.

I'm no expert but I'd think at that frequency you'd be better off building a board based around a DSP, no? Much cheaper than an FPGA...

Yeah, it's not properly integrated with the original workflow. I think there are intentions to do that at some point, contingent on the usual open source caveats (time, desire, etc.). But, for now, it is a functioning proof-of-concept. :)
