AUTOMATIC SPATIAL CALIBRATION FOR A LOUDSPEAKER SYSTEM USING ARTIFICIAL INTELLIGENCE AND NEARFIELD RESPONSE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18195879 titled 'AUTOMATIC SPATIAL CALIBRATION FOR A LOUDSPEAKER SYSTEM USING ARTIFICIAL INTELLIGENCE AND NEARFIELD RESPONSE
Simplified Explanation
The patent application describes a method for automatically calibrating the spatial positioning of loudspeakers in a listening area.
- The method uses a machine learning model to estimate the distances between the loudspeakers and the listening area.
- It also estimates the propagation delays from the loudspeakers to the listening area.
- Based on these estimates, the method further calculates the incidence angles of the loudspeakers relative to the listening area.
- Spatial perception correction is then applied to the audio reproduced by the loudspeakers.
- The correction includes delay and gain compensation to address any misplacement of the loudspeakers relative to the listening area.
Original Abstract Submitted
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.
