Beschreibung
Zusammenfassung:	A device is operative to locate a target audio source. The device includes multiple microphones arranged in a predetermined geometry. The device also includes a circuit operative to receive multiple audio signals from each of the microphones. The circuit is operative to estimate respective directions of audio sources that generate at least two of the audio signals; identify candidate audio signals from the audio signals in the directions; match the candidate audio signals with a known audio pattern; and generate an indication of a match in response to one of the candidate audio signals matching the known audio pattern.
