摘要： The method for adapting a sound converter to a reference sound converter includes the sound converter having a first linear transfer function with a first frequency response, a second linear transfer function with a second frequency response, and a trivial nonlinearity. The sound converter has a non-linear transfer function corresponding to the frequency response from combination of the first linear transfer function, the trivial nonlinearity, and the second linear transfer function. A first frequency spectrum of the reference sound converter is determined at a low input level. A second frequency spectrum of the reference sound converter is determined at a high input level. The second determined frequency spectrum is used as the second frequency response in the second linear transfer function, and the division of the first frequency spectrum by the second frequency spectrum is used as the first frequency response in the first linear transfer function.

摘要： A method is proposed for adapting a sound converter to a reference sound converter at a target setting of an analog circuit of the reference sound converter. The sound converter has a sound transfer function. The analog circuit is digitally modeled by an analog function. At a default setting of the analog circuit, parameters of the sound transfer function of the sound converter are adapted to the reference sound converter. An analog function inverse to the analog function with default analog parameters corresponding to the default setting and the analog function with target analog parameters corresponding to the target setting are applied before or after the sound transfer function. Furthermore, a sound converter adapted for carrying out the method is proposed.
