This paper discusses an application of block-oriented modeling to a popular analog dynamic range compressor using iterative minimization. The reference device studied here is the UREI 1176LN, which has been widely used in music production and recording. A clone of the circuit built in a previous project has been used as a reference device to compare the results of the implementation. A parametric block-oriented model has been designed, improved, and tuned using the Levenberg-Marquardt iterative error minimization algorithm. Only input/output measurements have been performed following a gray-box modeling approach. Finally the model has been evaluated with objective scores and a listening test. This work led to very convincing modeling results.
