Sound field calibration using listener localization
View Patent ↗An example implementation involves a first device receiving, from a sensor, first location data that is associated with the first device, and, from a second device, second location data that is associated with the second device. The first device determines a first location of a listener relative to the first device based on the first and second location data. The first device generates a first sound field during media content playback based on the determined first location. The first device receives, from the sensor, third location data that is associated with the first device, and, from the second device, fourth location data associated with the second device. Based on the third and fourth location data, the first device determines a second location of the listener relative to the first device. Based on the second determined location, the first device generates a second sound field during media playback.
