The present invention relates to a method and to an apparatus, both arranged for controlling acoustic signals to be recorded or reproduced by an electro-acoustical sound system. For this purpose: an initial digital filter is determined by solving an inverse problem, wherein the initial digital filter is configured to control acoustic signals to be recorded and/or reproduced by the electro-acoustical sound system; a frequency-dependent articulation parameter is determined by executing a time spectral psychoacoustic automatic audio quality test on the initial digital filter; a frequency-dependent regularization parameter, used for determining the initial digital filter, is tuned by use of the frequency-dependent articulation parameter; and, by use of the tuned frequency-dependent regularization parameter, a digital filter configured to control acoustic signals to be recorded or reproduced by the electro-acoustical sound system

Abstract

The present invention relates to a method and to an apparatus, both arranged for controlling acoustic signals to be recorded or reproduced by an electro-acoustical sound system. For this purpose: an initial digital filter is determined by solving an inverse problem, wherein the initial digital filter is configured to control acoustic signals to be recorded and/or reproduced by the electro-acoustical sound system; a frequency-dependent articulation parameter is determined by executing a time spectral psychoacoustic automatic audio quality test on the initial digital filter; a frequency-dependent regularization parameter, used for determining the initial digital filter, is tuned by use of the frequency-dependent articulation parameter; and, by use of the tuned frequency-dependent regularization parameter, a digital filter configured to control acoustic signals to be recorded or reproduced by the electro-acoustical sound system
