APPARATUS FOR PROVIDING AN AUDIO SIGNAL FOR REPRODUCTION BY A SOUND TRANSDUCER, SYSTEM, METHOD AND COMPUTER PROGRAM

摘要

An apparatus for processing an audio signal for reproduction by a sound transducer includes an equalization parameter determinator for determining a set of equalization parameters and an equalizer configured to equalize an input audio signal, to obtain an equalized audio signal. Different concepts for the determination of the set of equalization parameters include 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.

1. A system, comprising:
a global equalization database, which defines an association between types of sound transducers and corresponding sets of equalization parameters and which is accessible by multiple apparatuses for processing an audio signal of multiple users, such that it is possible to share an equalization parameter setting identified by a user with other users; an apparatus for processing an audio signal for reproduction by a sound transducer, the apparatus comprising:
an equalization parameter determinator for determining a set of equalization parameters; andan equalizer configured to equalize an input audio signal, to acquire an equalized audio signal;wherein the equalization parameter determinator is configured to set the equalization parameters in dependence on a user input from a user interface; andwherein the equalization parameter determinator is configured to upload the set of equalization parameters and an information about the sound transducer to the global equalization database, which is accessible by multiple apparatuses for processing an audio signal of multiple users, such that it is possible to share an equalization parameter setting identified by a user with other users.
