Audio fencing system and method

A system comprising:

• at least one microphone configured to:
• deploy a first microphone lobe towards a first location to capture one or more first audio signals from a first audio source located within a first audio pick-up region, and
• deploy a second microphone lobe towards a second location to capture one or more second audio signals from a second audio source located outside the first audio pick-up region;
• and
• at least one processor communicatively coupled to the at least one microphone and configured to remove off-axis noise from the one or more first audio signals by applying, to the one or more first audio signals, a mask determined based on the one or more second audio signals.

A non-transitory computer-readable storage medium comprising instructions that, when executed by at least one processor, cause the at least one processor to perform:

• deploy, using at least one microphone, a first microphone lobe towards a first location, the first microphone lobe configured to capture one or more first audio signals from a first audio source located within a first audio pick-up region;
• deploy, using the at least one microphone, a second microphone lobe towards a second location, the second microphone lobe configured to capture one or more second audio signals from a second audio source located outside the first audio pick-up region;
• and
• remove off-axis noise from the one or more first audio signals by applying, to the one or more first audio signals, a mask determined based on the one or more second audio signals.
