Real-Time Circuit Simulation with Wave Digital Filters in C++ Pt. 2

Abstract Real-time circuit simulation is a common challenge in audio signal processing, as many digital synthesizers and audio effects are based on emulations of existing analog hardware. Wave Digital Filters (WDFs) are a powerful tool for modelling the behaviour of electronic circuits. We'll give a brief introduction to the theory behind wave digital filters, and discuss the implementation of a C++ WDF library designed to perform circuit simulations in real-time. Along the way, we'll see how C++ concepts including object-oriented programming, template meta-programming, and RAII, have factored into the design of the library.
