1. A system for detecting a gunshot comprising:
a device for capturing acoustic data that is potentially sound emanating from an actual gunshot;
circuitry configured to receive electrical signals and to generate digital signals comprising digital data which corresponds to the received acoustic data;
a processor including non-transitory, computer-readable medium comprising computer-executable instructions for determining whether the captured acoustic data or sampled portions of the captured acoustic data contains an ultrasonic burst that corresponds to an ultrasonic signature of an actual gunshot having contiguous ultrasonic component sound frequency content in excess of 20 kHz,
whereby the determination is used to identify an actual gunshot and distinguish it from that of a sound burst that is not an actual gunshot.
