General questions on mp3 Surround, mp3 SX, and mp3D

Are mp3 Surround files much bigger than regular mp3 files?

No, fortunately not. The algorithm used in mp3 Surround employs psychoacoustics to recreate the surround image out of very compact spatial information. By adding surround information, mp3 file sizes increase by just about 10 percent.
