CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe nonlinear 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 nonlinear convolution is based on the Volterra series approach and enables real time nonlinear 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.
