Non linear convolution and its application to audio effects

none1noThe non linear convolution could be applied to enhance the linear convolution on acoustic musical instruments and audio devices. In this paper a novel technology, based on exponential sine sweeps measurements, is presented. The non linear convolution is based on the Volterra series approach and enables real time non linear emulation of acoustic devices (as valve amplifiers and musical instruments). The new developed tool (a VST plugin developed in C++ in JUCE framework) will be presented. The emulation of musical instruments will be compared with real recordings. The results will be finally analyzed and commented.L'articolo presenta i risultati della ricerca che ha condotto ad un brevetto internazionale dell'Alma Mater StudiorumnoneL. TRONCHINL. TRONCHI
