Abstract
A system and method is configured to generate a sound wave field around a listening position in a target loudspeaker-room-microphone system in which a loudspeaker array of K≥1 groups of loudspeakers is disposed around the listening position, and a microphone array of M≥1 groups of microphones is disposed at the listening position. The system and method include equalizing filtering with controllable transfer functions in signal paths upstream of the K groups of loudspeakers. The system and method further include controlling with equalization control signals of the controllable transfer functions for equalizing filtering according to an adaptive control algorithm based on error signals and an input signal. The microphone array includes at least two first groups of microphones that are annularly disposed around a listener's head, around or in an artificial head or around or in a rigid sphere.
