Apparatus And Method For Automatic Adaption Of A Loudspeaker To A Listening Environment

Abstract: An apparatus (100) for processing an audio input signal comprising one or more audio input channels to obtain an audio output signal comprising one or more audio output channels according to an embodiment is provided. The apparatus (100) comprises an estimation unit (110) configured to estimate a radiation resistance of each driver of one or more drivers of each loudspeaker of one or more loudspeakers as an estimated radiation resistance; or configured to estimate a radiation impedance of each driver of the one or more drivers of each loudspeaker of the one or more loudspeakers as an estimated radiation impedance, wherein said estimated radiation impedance of said driver comprises estimated information on the radiation resistance of said driver. Moreover, the apparatus (100) comprises a processing unit (120) configured to obtain the one or more audio output channels by processing each audio input channel 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 the estimated radiation impedance of each driver of the one or more drivers of each loudspeaker of the one or more loudspeakers, the estimation unit (110) is configured to estimate the estimated radiation resistance or the estimated radiation impedance depending on estimated sound pressure information indicating an estimation of sound pressure at said driver of said loudspeaker, and depending on estimated velocity information indicating an estimation of a driver velocity of said driver of said loudspeaker.
