1. A system comprising:
- a microphone array; and
a control system coupled with the microphone array, the control system programmed to control the microphone array by;
processing a signal from a beacon device to identify a physical location of the beacon device relative to the microphone array; and
focusing the microphone array in a direction based upon the physical location of the beacon device prior to receiving an audio input at the microphone array,wherein the beacon device includes a negation mode for pre-focusing the microphone array away from the beacon device.

14. A system comprising:
a control system programmed to control a microphone array by; providing a prompt to initiate at least one noise source for sampling using the microphone array; receiving a set of noise source samples of the at least one noise source at the microphone array; creating a microphone array filter configured to at least partially reject the at least one noise source from the set of noise source samples; and storing the microphone array filter in a library of microphone array filters. - View Dependent Claims (15, 16, 17, 18, 19, 20)
