DIRECTIONAL AUDIO MICROPHONES IN A SURVEILLANCE SYSTEM

A system may be configured to implement directional audio capture via digital signal processing on audio captured by an array of microphones. In some aspects, the system may include a video capture device, a microphone array coupled to the video capture device, and a processing device. Further, the...

Zusammenfassung:	A system may be configured to implement directional audio capture via digital signal processing on audio captured by an array of microphones. In some aspects, the system may include a video capture device, a microphone array coupled to the video capture device, and a processing device. Further, the processing device may be configured to determine directional instruction information for the microphone array, the directional instruction information corresponding to a virtual capture direction for the microphone array, and generate a digital signal processing (DSP) plan based on the virtual capture direction. In addition, the processing device may be further configured to apply the processing plan to the plurality of audio captures captured by the microphone array to produce an audio output corresponding to the virtual capture direction.
