The Intersection of Analog and Digital Audio Processing
An Introductory Guide to Virtual Analog Modelling
Audio circuits, such as guitar pedals and amplifiers, process input signals to output signals with specific audio effects. The process of replicating the electrical behaviour of these circuits in a digital environment is known as Virtual Analog (VA) modelling. This session aims to provide a basic understanding of VA modelling and explore various methods to achieve it. Finally, using these methods as a foundation, we will look at modelling the circuit of the MXR Distortion+ guitar pedal and examine the process of creating a real-time safe audio plugin that emulates the reference circuit’s behaviour.
