Distortion, Saturation, and ClippingElement-Wise Processing: Nonlinear Effects

10.1 Introduction: Linear and Nonlinear Processing

Methods of processing a signal by multiplying and/or adding a scalar to each element are linear types of processing. All processing methods presented previously are based on linear processing. Nonlinear processing is based on methods other than scalar multiplication and addition.

10.1.1 Audio Distortion Effects

Audio distortion effects process signals using a nonlinear function. There are many audio effects categorized as distortion effects including overdrive, fuzz, harmonic saturation, and aural exciters. Additionally, many audio technologies process signals in a nonlinear manner such as guitar tube ...
