General questions on mp3 Surround, mp3 SX, and mp3D

What is mp3D?

mp3D improves the quality of audio playback on headphones. Stereo music is enhanced to create a wider sound image and a more pleasant listening experience. Surround sound can be played back with mp3D on any set of stereo headphones, simulating the natural reception of multi-channel sound by the human ear. mp3D calculates the sounds that reach the ears from loudspeakers, reflections and echoes of a listening room. The "out-of-head" localization and the feeling of spatiality achieved that way increases the listening comfort noticeably compared to traditional stereo headphone listening. mp3D can be combined with mp3 Surround and mp3 SX.
