Abstract

An apparatus (100) for processing an input audio signal (122) for reproduction by a sound transducer (130) comprises an equalization parameter determinator (110) for determining a set of equalization parameters (112) and an equalizer (120) configured to equalize the input audio signal (122) to obtain an equalized audio signal (124). Different concepts for the determination of the set of equalization parameters (112) comprise an image recognition an evaluation of an identification signal which is provided by the sound transducer via an audio connection and a measurement of the impedance of the sound transducer over frequency. Also an upload functionality and a download functionality are provided.
