摘要： One embodiment provides a method of automatic loudspeaker directivity adaptation. The method comprises measuring one or more room impulse responses (RIRs) from one or more loudspeakers to one or more microphones of the one or more loudspeakers, estimating reverberation time and clarity based on the one or more RIRs, and estimating one or more positions of the one or more loudspeakers based on the one or more RIRs. The method further comprises automatically adapting directivity of the one or more loudspeakers based on the reverberation time estimated, the clarity estimated, and the one or more positions estimated.

摘要： One embodiment provides a computer-implemented method that includes acquiring, via at least one microphone, sound pressure data at one or more discrete frequencies obtained from a frequency response of a loudspeaker in a room. The sound pressure data is input into an artificial intelligence (AI) model that analyses and processes information, and that incorporates a relationship between the frequency response and at least one of an energy average (EA) in a listening area or a total sound power (TSP) produced by the loudspeaker. The AI model automatically estimates, without user interaction, the at least one of the EA in the listening area or the TSP produced by the loudspeaker.

摘要： 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.

摘要： A method includes detecting, by a speaker system including a microphone, one or more boundaries within a proximity to the speaker system. The speaker system adjusts an output of the speaker system based on the one or more detected boundaries. A sound quality of the speaker system is improved based on adjusting the output.
