Real-Time Digital Modeling of Analog Circuitry for Audio Applications

Abstract

The goal of this project was to develop a scalable digital signal processing platform capable of modeling analog audio circuits using state-space modeling techniques. Using circuit theory as a foundation, the analog models were built around time-domain solution of circuit analysis. The resultant platform was capable of indistinguishably modeling variable analog filter circuits, with order being only restricted by hardware capabilities. Various continuous-to-discrete time conversion methods were investigated to determine the optimal sounding and performing algorithm
