Zusammenfassung:	Embodiments of the present disclosure include an apparatus (116) configured to perform beamforming on multiple audio input signals. The apparatus (116) includes a first plurality of microphones (302, 502) configured to resolve first audio input signals within a first frequency range. The apparatus (116) also includes at least one microphone (504) configured to resolve second audio input signals within a second frequency range. A lowest frequency in the first frequency range is greater than a lowest frequency in the second frequency range.
