Neo6 is one of a bunch of "expand stereo content out to multiple channels" algorithms -- like Dolby Pro Logic (PL), PLII, the Logic7 algorithm offered by Harman Kardon and others. Different recordings sound best with different algorithms, but many of us find that Neo6 is a good choice for most stereo content.

It's not the same as a real 5+ channel recording (DVD, DVD-A, SACD) with 5 or more channels cabled from the player to the receiver, but it can sound really good anyways.
