Abstract
In one implementation, an apparatus includes a camera, a loudspeaker, a plurality of microphones, and a controller. The apparatus may be a computer, a mobile device such as a smart phone, or a dedicated videoconference device. The plurality of microphones are configured to produce sound data. A first number of the plurality of microphones are arranged on a first side of the loudspeaker, and a second number of the plurality of microphones are arranged on a second side of the loudspeaker. Different quantities of the microphones may be included on each side of the loudspeaker. The controller is configured to calculate a cross-correlation of the plurality of microphones based on the sound data and attenuate the cross-correlation based on a time-delay window and an attenuation factor. A participant location is determined based on the attenuated cross correlation functions.
