Virtual analog modeling is the practice of digitally emulating analog audio gear. For many years, because of the limited amount of computational power, only the emulation of nonlinear audio circuits containing few one-port nonlinearities was tabled. Recently, with the rise of high-performing processors, different techniques have been proposed to accomplish the emulation of increasingly complex circuits. Among white-box methods, Wave Digital Filters (WDFs) are gaining resounding success thanks to their remarkable features, such as stability, accuracy, and efficiency. This talk first provides background knowledge on WDFs and then addresses the latest research trends and developments regarding the emulation of audio circuits with multiple one-port nonlinearities in the Wave Digital domain.
