Yes and yes, kind of.
If you just want to make your room sound better, talk to GIK for help.
If you want to see what your room "sounds like" I like OmniMic a lot, but most people use Room EQ Wizard.
You can't fix everything wrong with room acoustics with Dirac, but you can adjust it. The best approach is a combination of room acoustics and appropriate equalization such as from Dirac.
