Abstract
A system enhances spatialization in which spatial information about sound sources at an originating location is represented in an audio signal. The system applies a phase difference analysis to the signals received from an array of spaced apart input devices or microphones to derive spatial or directional information about the relative directions of one or more satellite input devices or microphones. The signals from the satellite input devices or microphones are mixed by a function of their respective directions to generate a multichannel output signal. When processed by a remote or local system, the output signal provides a representation of the relative directions of the sound sources at the originating location at a receiving location.
