DSP Room Corrections has been in use in the home cinema market for years, (Its been built in to pretty much all AV receivers for years (With some better than others) higher end Hi-Fi amps also have it, plus there are plenty of similar options if you are using a computer based system. (My favourites are Dirac, ARC (Anthem) and Room Perfect)
It is not however a magic fix for a bad room (You will need to do some room treatment first) but to finish off it is great.
A lot of HC subwoofers also have it built in. (The lower frequency's are what benefit the most)
A calibrated mic and mic stand are also essential to get the best results. (A lot of High End amps and receivers come with them)
There are also external modules and plug-ins available.
Best way to run Roon is via a NAS, as it makes it easy to service as many Roon players as you want.
Have fun using it, and don't be afraid to fine tune it to your personal preferences.
