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).
