Room correction, DSP for dummies.

I have not paid a lot of attention to audio for some time, almost 15 years and as a result I am trying to catch up on some of the innovation and tech developments that have been popping up in that time. 

One of the more interesting to me is the advent of electronically guided digital signal manipulation to help quell small system issues and room reflections. It seems wildly promising but  the few systems that I have read about that seem to work well look to be  painfully expensive. 

Reports have seemed to indicate that this technology was making its way into other, more affordable formats but I guess I just don't understand or grasp where the field is going well enough to know where the bulk of the technology is and how its manifesting in our hobby. 

Who can help shed some light on where this tech is, how  its being applied and how can I make use of it without selling a kidney? Maybe that last part is not possible yet? 

Thanks in advance!

OP: My recommendation is to buy a calibrated microphone, a miniDSP mic goes for $100 on Amazon, and down load the free Room Eq Wizard (REW) software and measure your own room. Based on that data, you could have a more meaningful discussion about what DSP can do to improve your room/ speaker acoustics.

I’ve done the measurements and it’s a lot of fun.  You can get a miniDSP equalizer for $200 and program it with the same tools you used to measure the room.  It works as advertised. My room/ speaker set up has some SBIR issues but DSP cannot fix a null.  In the end, I didn’t use DSP.  I did some room treatment (a more general solution) and was satisfied.
