    It's so nice to see an update to this software in 2017. I though the project would be dead after having stopped releases in 2012. This software deserves five stars for the reason alone that there is no freely available software than can do DRC like this can. I've looked at a lot of the commercial alternatives (Acourate, Dirac, and others) but all they have restrictions in their useability if you don't want to conform to the manufacturer's vision of how to use their software. I do my DRC all with freeware tools. I measure the impulses with Room EQ Wizard - it's become somewhat of a standard in that regard and it's easy to compare the measurements to other people's. The resulting conolver files are then convolved by EqualizerAPO which is also used as crossover - if you only listen to stereo a 5.1 soundcard is very handy in that regard. I also gain the advantage of having the correction for the whole system, not just a single playback application like foobar2000 or JRiver. This means my audio is always correct - YouTube, movies, games, whatever. Of course, that requires you to have a PC as central playback station. I even route my turntable into my PC for this reason. From there, I go directly into several power amplifiers. The acoustic performance this enables me for literally 0 bucks spent is amazing. Plus I get to do things my way without being restricted to some manufacturer's choices.

    Sorry to see that it is completely and only Windows. No linux (or mac) config can be seen. Why?

    I'm having a lot of fun with this software and I'm only scratching the surface yet. I use it to straighten out my Full Range Line Arrays, home brewed. More info on my journey can be found on DIYaudio if you look for The Two Towers, a 25 driver full range line array. I hope the interest in this great piece of software will rise again, I will do my part to ensure it will. For people trying to get their feet wet, start with something like DRC Designer and move on from there. A big thank you to Dr. Denis Sbragion for developing this tool.
