Method, apparatus, and computer-readable media focusing sound signals from plural microphones in a 3D space, to determine audio signal processing profiles to optimize sound source(s) in the space. At least one processor determines plural virtual microphone bubbles in the space, and defines one or more bubble object profiles which comprise(s) specific attributes and functions of audio processing functions for each bubble, each bubble object profile including: (a) an individual bubble object profile when the bubble has been configured for an individual bubble; (b) a region object profile when the bubble has been configured for a region of one or more bubbles; and (c) a group object profile when the bubble has been configured for a group having one or more bubbles. The audio signal processing functions are used for the at least one bubble, for any combination of (a), (b), and (c).

Method, apparatus and computer-readable media to create audio focus regions dissociated from the microphone system for the purpose of optimizing audio processing at precise spatial locations in a 3D space

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.
