Abstract:
1. A method for optimizing acoustic localization at least at one listening position in a listening environment, comprising: generating a sound field by a group of loudspeakers assigned to the at least one listening position, where the group of loudspeakers includes a first and at least a second loudspeaker, and where each loudspeaker receives an audio signal from an audio channel; calculating filter coefficients of a phase equalization filter for at least the audio channel supplying the second loudspeaker, where a phase response of the phase equalization filter is configured such that a binaural phase difference (Δφ filtering the respective audio channel with the phase equalization filter; where the calculating of the filter coefficients of the phase equalization filter comprises performing a minimum search within an array of phase differences dependent on frequency and phase-shifts for at least one audio-channel, where the minimum search provides an optimum phase function φ smoothing the optimum phase function φ performing the smoothing of the optimum phase function φ
