  • Measurement and calibration of a networked loudspeaker system
    Patent number: 10425759
    Abstract: A system and method for measuring and calibrating a time-synchronized network of loudspeaker participants. Each loudspeaker participant has a plurality of microphone arrays. The system and method generates a stimulus signal at each network participant and records precise sensor data including start and end timestamps of the stimulus signal. The sensor data is compiled to estimate locations of loudspeaker participants within the time-synchronized network to establish a global frame of reference for all of the loudspeaker components in the network.
    Type: Grant

  • Environment discovery via time-synchronized networked loudspeakers
    Patent number: 10412532
    Abstract: A method for creating a model of reflective surfaces in a listening environment that may be applied to noise cancellation for a network of AVB/TSN loudspeaker components. A coordinator determines co-planarity and estimates orientation of all echoes of a stimulus by using recorded precise times of arrival, determined angles of arrival and the known, or estimated, locations of each loudspeaker component. The coordinator groups reflection points into planar regions based on co-planarity and estimated orientations to determine a location of each reflective surface in the listening environment thereby creating a model of all of the reflective surfaces in the listening environment.
