Title: AUDIO DEVICE FILTER MODIFICATION
Abstract:
An audio device with a number of microphones that are configured into a microphone array. An audio signal processing system in communication with the microphone array is configured to derive a plurality of audio signals from the plurality of microphones, use prior audio data to operate a filter topology that processes audio signals so as to make the array more sensitive to desired sounds than to undesired sounds, categorize received sounds as one of desired sounds or undesired sounds, and use the categorized received sounds and the categories of the received sounds to modify the filter topology.
