Abstract:
1. A system for optimization of three-dimensional audio listening having a media player and a multiplicity of speakers disposed within a listening space, said system comprising: a portable sensor having a timing unit for receiving test signals from said speakers and for transmitting a signal based on said test signals to a processor connectable in the system, wherein said portable sensor has a multiplicity of transducers strategically arranged thereabout to define the disposition of each of said speakers, both in the horizontal plane as well as in elevation, with respect to the location of the portable sensor, said processor including: a) means for initiating transmission of test signals to at least one of said speakers and to said timing unit for receiving said test signals from said speakers to be processed for determining the location of each of said speakers relative to a listening place within said space determined by the placement of said sensor; b) means for manipulating each sound track of said multi-channel sound signals with respect to intensity, phase and/or equalization according to the relative location of each speaker in order to create virtual sound sources in desired positions, and c) means for communicating between said sensor and said processor.
