Digital signal processing is mainly based on linear time-invariant systems. The assumption of linearity and time invariance is for sure valid for a great variety of technical systems. Especially for the systems where input and output signals are bounded to a specific amplitude range. To be precise, several analog audio process…

Nonlinear Audio Processing. Digital filtering can improve audio signals in many ways. For instance, Wiener filtering can be used to separate frequencies that are mainly signal, from frequencies that are mainly noise (see Chapter 17). Likewise, deconvolution can compensate for an undesired convolution, such as in the restoration of old recordings (also discussed in …
Complex Nonlinearities for Audio Signal Processing
https://ccrma.stanford.edu/~jatin/papers/Complex_NLs.pdf
INTRODUCTION In digital audio signal processing it is common to find audio ef- fects that use nonlinear elements to add harmonic content to the signal being processed, or to achieve a “distortion” type of effect. Typically, this is done either as part of an analog model, or using a static memoryless nonlinear element.

Hence, audio nonlinear systems should be identified when they are excited by their real inputs (natural audio signals). But the properties of audio signals make them unsuitable for classical identification algorithms, since they are generally non-Gaussian, non …

Audio effect algorithms for dynamics processing, valve simulation, overdrive and distortion for guitar and recording applications, psychoacoustic enhancers and exciters fall into the category of nonlinear processing. They create intentional or unintentional harmonic or inharmonic frequency components which are not present in the input signal.

As you have stated in the first sentence of your post (post #6), hearing aids perform non-linear processing of the audio signal, and therefore their behavior is intentionally non-linear. The audio equipment we discuss in this forum are supposed to function linearly. (I'll leave those devices that add non-linear "euphoric distortions" to a separate discussion.) When …
