  • Detection of microphone orientation and location for directional audio pickup
    Patent number: 11425502
    Abstract: Methods and a system that automatically determines the spatial relationship of microphone assemblies with respect to a camera of a video conference endpoint through audio signal processing. The video conference endpoint may include at least a microphone assembly and a loudspeaker. The microphone assembly may include a plurality of co-located directional microphones. The video conference endpoint may detect, by the plurality of co-located directional microphones of the microphone assembly, audio emitted from the loudspeaker of the video conference endpoint. The video conference endpoint may then generate data representing a spatial relationship of the microphone assembly with respect to the loudspeaker based on a compilation of the audio detected by the co-located directional microphones of the microphone assembly.
