A method for automated setting of digital processing parameters intended to be applied to digital signals before broadcast by at least one loudspeaker placed in an environment. The method includes a step of determining a set of frequency responses of the environment, an equalization step applied for each subset of at least one loudspeaker and a second equalization step applied to at least one subset of at least one loudspeaker. A device for the implementation of the method is also provided.

Method for automated setting of digital processing parameters applied to signals before broadcast by loudspeakers and device for the implementation of such a method

A method for controlling the distortion generated by a system having at least one loudspeaker on board a vehicle, the loudspeaker being designed to receive an audio signal. The method includes measuring at least one indicator of the distortion of the at least one loudspeaker, determining an acceptable distortion threshold for each distortion indicator, which can be used to determine a maximum acceptable amplitude for each frequency in a frequency range of interest of the audio signal entering the loudspeaker system, generating an assembly comprising at least one filter, correcting the audio signal entering the loudspeaker system by applying at least one filter determined in the generating step.
