Automatic spatial calibration for a loudspeaker system using artificial intelligence and nearfield response

A system of automatic spatial calibration, comprising:

• at least one processor;
• and
• a non-transitory processor-readable memory device storing instructions that when executed by the at least one processor causes the at least one processor to perform operations including:
• 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;
• 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;
• and
• 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, wherein 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.

A non-transitory processor-readable medium that includes a program that when executed by a processor performs a method of automatic spatial calibration, the method comprising:

• 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;
• 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;
• and
• 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, wherein 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.
