Microphone array with automated adaptive beam tracking

An apparatus, comprising:

• a processor configured to:
• modify, via a central controller, based on an acoustic stimulus, at least one control function associated with at least one microphone and at least one loudspeaker, of a plurality of loudspeakers, to minimize acoustic feedback produced by the at least one loudspeaker;
• output, from each loudspeaker of the plurality of loudspeakers, the acoustic stimulus, at a known signal level, one loudspeaker zone at a time, wherein each loudspeaker zone comprises one or more of the least one loudspeaker;
• and
• determine a delay for each combination of the at least one microphone and the each loudspeaker of the plurality of loudspeakers;
• wherein when a measurement of an acoustic gain is less than a predefined threshold value, a feedback decay rate is set based on the acoustic gain to minimize the acoustic feedback.

A non-transitory computer readable storage medium configured to store at least one instruction that when executed by a processor causes the processor to perform:

• modifying, via a central controller, based on an acoustic stimulus, at least one control function associated with at least one microphone and at least one loudspeaker, of a plurality of loudspeakers, to minimize acoustic feedback produced by the at least one loudspeaker;
• outputting, from each loudspeaker of the plurality of loudspeakers, the acoustic stimulus, at a known signal level, one loudspeaker zone at a time, wherein each loudspeaker zone comprises one or more of the least one loudspeaker;
• and
• determining a delay for each combination of the at least one microphone and the each loudspeaker of the plurality of loudspeakers;
• wherein when a measurement of the acoustic gain is less than a predefined threshold value, a feedback decay rate is set based on the acoustic gain to minimize the acoustic feedback.
