Dynamic range compression (DRC) systems reduce the dynamic range of an input signal by amplifying low amplitude levels and attenuating higher ones. This work describes a method to digitally model any analog dynamic range compression unit solely with the help of input/output measurements. For this purpose a generic dynamic range compression model is chosen and its structure is adapted to be able to recreate an analog reference device. The linear characteristic as well as the static curve of the reference device are extracted and directly used in the model. Afterwards the parameters of the digital model are adapted with an iterative optimization routine. Finally the output of the digital model and the analog reference system are compared to evaluate the quality of the emulation.
