Method and apparatus for controlling acoustic signals to be recorded and/or reproduced by an electro-acoustical sound system

An apparatus configured to control acoustic signals to be recorded and/or reproduced by an electro-acoustical sound system, wherein the apparatus comprises:

• an initial digital filter determining entity configured to determine an initial digital filter 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 determining entity configured to determine a frequency-dependent articulation parameter by executing a time spectral psychoacoustic automatic audio quality test on the initial digital filter;
• a frequency-dependent regularization parameter tuning entity configured to tune a frequency-dependent regularization parameter, used for determining the initial digital filter, by use of the frequency-dependent articulation parameter;
• and
• a digital filter determining entity configured to determine, by use of the tuned frequency-dependent regularization parameter, a digital filter configured to control acoustic signals to be recorded and/or reproduced by the electro-acoustical sound system.
