Correcting room acoustical issues electronically is a very complex undertaking requiring sophisticated software and dedicated fast hardware . Doing proper measurements alone takes a massive amount of processing time because it involves running iterations of sweeps and adjustments. More calculations are required for the bass frequencies because of the nature of long wavelengths in the room.
The few programs that come close to doing it properly are the Audessey PRO which is very expensive and can be connected to a PC and takes a while to run; or Room EW which is free software used with a notebook. All the Audessey eq programs liscenced for receivers are ineffectual watered down versions with simplified algorythms designed to run just a few iterations, make computations then recommendations made on simplyfing assumptions. Those simplified rules rarely correspond with your unique room acoustical requirements.
That's why I always say that based on current technology in receivers, there is no way such a program can do as good a job as someone with a RS metre and a measurement tape. Perhaps one day they will as the technology gets better and the cost of processing falls but don't hold your breath anytime soon.
