It is called Audyssey. The difficult part of Audyssey is that there is no room for error and to make any mistakes. You need to work at mm precision.
Systems like Dirac are more easy to use, but they have a big limitation compared to Audyssey. When you use Audyssey the right way you will not loose low, mid and high frequency details compared to most other room correction systems.
