Patent ID: 10251015

Abstract:
Disclosed is a method for determining filter coefficients of an audio precompensation controller for the compensation of an associated sound system, including N≥2 loudspeakers, including estimating, for each one of at least a pair of the loudspeakers, a model transfer function at each of M control points distributed in Z≥2 spatially separated listening zones in a listening environment of the sound system. The method also includes determining, for each of the M control points, a zone-dependent target transfer function at least based on the zone affiliation of the control point; and determining the filter coefficients of the audio precompensation controller at least based on the model transfer functions and the target transfer functions of the M control points. Consequently, an audio precompensation controller for an associated sound system can be obtained that enables improved and/or customized sound reproduction in two or more listening zones simultaneously.
