Room Analysis-How?

So I’ve seen a number of YouTube videos and the like where people have conducted an analysis of their listening room or home theater to help optimize speaker placement, room treatment and subwoofer settings. It appears that they use a variety of software and microphones. And then the result is a series of graphs that show high and low spots in the frequency range.  And the it helps them with placement and room treatment. I like my system and it sounds pretty good to me in my room. That said, I’ve always been a little intellectually curious as to what the charts and graphs would say about my room. And if I could make it sound better.  So are there companies that do this sort of analysis you can hire? Or is there downloadable apps that are relatively dummy proof and user friendly while doing a good job?  Other?

Thanks to everyone that chimed in on this thread.  My wife was out of town this weekend which gave me the opportunity to spend a lot of time on Saturday and Sunday becoming a novice, yet capable user of REW and analyzing my room.  I also bought the Master Handbookf of Acoustics and began to read.  I've already learned a ton!  My analysis this weekend led me to make meaningful changes to my main speaker positions and primary listening spots.  I made sub woofer adjustments in the crossovers and volumes.  I experimented with moving certain furniture around.  I had a large null in the 200-230HZ range in the beginning that I've now worked to an acceptable level.  And then after all the adjustments I applied my ears and tweaked a little more.  My room, which was impressively pretty good before I even started this analysis (dumb luck I suppose, perhaps helped by a wife with good furniture/decoration taste and placement!) sounds better than ever!  This will be iterative over time.  I'm guessing I'll experiment with panels, diffusers and traps as time goes on.  Who knows.  But this was fun, my room is better today and I'm thankful to those of you who posted to encourage and guide my endeavors in acoustical analysis!
