I went thru the process of installing and implementing digital room correction on my vista pc that I use for listening on occasion. My observations:
Good - a real improvement in the sound, clearly and immediately audible, unlike cables, DACs. You do not have to listen carefully to hear the improvement. Results - better imaging, smoother sound, particularly in bass, but throughout mids and highs as well. You listen thru the system back to the recording in the most transparent way I have heard yet, and I have been an audiophile since the days of Large Advents. Free. Pure software solution.
Bad - a real hassle to set up - documentation too technical for most users. Command line programs. Multiple pieces to fiddle with. So revealing that bad mixes call attention to themselves. My setup is just for me sitting in front of the computer with my head between the speakers. Not sure how it would work in a more typical listening room. Test tones can fry your speakers.
If you go to DRC wikipedia you will find all the links you need to download the DRC software and other tools you need for free.
Have fun. If you are an audiophile and computer geek, it is worth it. This would be a fantastic setup for a recording engineer who sits between the monitors on either side of the computer. My monitors and subwoofer are decent but mid-fi but when in the sweet spot and with DRC turned on sound like a million bucks.
