Abstract
An audio conference system for automatically forming a single combined physical microphone array aperture across associated and/or disassociated ad-hoc microphone elements in a shared 3D space is provided. The audio conference system includes a plurality of microphone/speaker units, each including at least one microphone and/or at least one speaker and a system processor communicating with the microphone/speaker units. The system processor instructs the microphone/speaker units to transmit unique calibration signals sequentially or simultaneously and to calculate time difference of arrival (TDOA) between the microphone/speaker units. A physical array structure of the microphone/speaker units is obtained based on TDOA between the microphone/speaker units, and a consolidated target coverage zone common to the microphone/speaker units is generated based on the physical array structure.
