I just learned about Audyssey and it’s various technologies. One of them being MultEQ. I cannot speak of whether the concept / system works or not but it’s interesting to consider.
Quote:
“At the core of everything Audyssey creates is our first technology, MultEQ™. Based on 6 years and $6 million of research at the USC Immersive Audio Lab, MultEQ delivers accurate, enveloping, and distortion-free sound in any listening environment. It has won numerous awards and is the basis of several other Audyssey technologies. MultEQ has been established as the standard room correction technology for today’s leading audio products.”
