Abstract
Methods and apparatus are disclosed for processing an audio sound source to create four-dimensional spatialized sound. A virtual sound source may be moved along a path in three-dimensional space over a specified time period to achieve four-dimensional sound localization. The various embodiments described herein provide methods and systems for converting existing mono, 2-channel and/or multi-channel audio signals into spatialized audio signals have two or more audio channels. The incoming audio signals may be down-mixed, up-mixed or otherwise translated into fewer, greater or the same number of audio channels. The various embodiments also describe methods, systems and apparatus for generating low frequency effect and center channel signals from incoming audio signals having one or more channels.
