Equipment, systems, and methods for processing audio input signals for automatic adaption of speakers to the listening environment

Abstract

The invention relates to an apparatus, system and method for processing audio input signals for the automatic adaptation of a loudspeaker to the listening environment, apparatus (100) for processing audio input signals including one or more audio input channels to obtain an audio output signal including one or more audio output channels. The device (100) includes an estimator (110) configured to estimate the radiation resistance of each driver in one or more drivers of each loudspeaker in one or more loudspeakers for which the radiation resistance is estimated; or configured to estimate the radiation impedance of each driver among one or more drivers of each speaker among one or more speakers as estimated radiation impedance, wherein the estimated radiation impedance of the said driver includes estimated information about the radiation resistance of that driver. In addition, the device (100) includes a processor (120) configured to obtain one or more audio output channels by processing each of the one or more audio input channels depending on the estimated radiation resistance or depending on the estimated radiation impedance of each of the one or more drivers of each of the one or more loudspeakers, To estimate the estimated radiation resistance or estimated radiation impedance of each driver among one or more drivers of each loudspeaker in the number of one or more loudspeakers, The estimator (110) is configured to estimate the estimated radiation resistance or estimated radiation impedance depending on the estimated sound pressure information which gives the estimated sound pressure at the specified driver of the specified loudspeaker and depending on the estimated velocity information which gives the estimated velocity of the specified driver of the specified loudspeaker.
