Abstract: In one embodiment, a method includes determining human directivity index (DI) pattern data corresponding to a location of a listener, based on vocalization recorded by a microphone at each of a plurality of loudspeakers. The method further includes extracting a set of DI features from the DI pattern data; providing the set of DI features to a trained machine-learning model; and determining, by the trained machine-learning model and based on the set of DI features, a placement of each of the plurality of loudspeakers relative to the listener.

Abstract: One embodiment provides a method of automatic spatial calibration. The method comprises estimating one or more distances from one or more loudspeakers to a listening area based on a machine learning model and one or more propagation delays from the one or more loudspeakers to the listening area. The method further comprises estimating one or more incidence angles of the one or more loudspeakers relative to the listening area based on the one or more propagation delays. The method further comprises applying spatial perception correction to audio reproduced by the one or more loudspeakers based on the one or more distances and the one or more incidence angles. The spatial perception correction comprises delay and gain compensation that corrects misplacement of any of the one or more loudspeakers relative to the listening area.
