I have used Audessey XT32, YPAO, MCACC, and Dirac. IME, Dirac is probably the best of the bunch.
There are two room correction programs, Audiolense and Acourate, that I have used for 2 channel music and they are next level. Mitch Barnett has written several articles on both of these programs on Audiophilestyle.com. Mitch is the proprietor of Accurate Sound and offers DSP room correction service for those that don’t want to spend the time learning the programs. He is extremely knowledgeable and patient. These programs reside on your laptop. One measures their listening room with a calibrated mic and develops convolution filters that are loaded into ROON or JRiver. The improvement is not subtle. Highly recommended.
