AB  - In many sound synthesis applications, once the salient properties of a sound source are defined, equalization is undertaken in order to fit it to the musical context. This is normally done by linear filters.When the sound synthesis algorithm, however, is as flexible as a physical model, Computational Sound Design techniques can be employed to perform offline equalization at the model level, saving real-time computational resources. In this work we extend the use of a recently proposed algorithm, MORIS, to equalize the harmonic content of a synthesized sound obtained by physical modeling according to equalization curves. We evaluate the effectiveness of the approach by considering an open-source clarinet model and pipe organ physical model, comparing our results with those obtained by online filtering and showing the advantages of the new method.
