Amplitude distortion is the unintended modification of a signal, typically while undergoing amplification. Amplitude modulation, in contrast, is the intended modification of a carrier wave in response to a varying audio, video or other information-bearing signal.

DISTORTION/FUZZ • Hard symmetrical clipping, producing a hasher sound. A non-linear function commonly used to simulate distortion/fuzz is given by: = | | (1− 𝑥2 𝑥) • This a non-linear exponential function. The gain, a, controls level of distortion/fuzz. • Output v/s input curve is more non-linear than that of Overdrive and produces a
Types of Audio Distortion
https://parallelhomeaudio.net/TypesAudioDistortion.html
Audio distortion can be placed in two broad categories. Type 1 — linear, altered amplitude content. Type 2 — nonlinear, added frequency content. Type 1 is also known as frequency response, which involves both amplitude (changes in the volume)and phase errors. These distortions can be corrected with signal processing.
Capacitor Distortion - Audio Amplifier Design

The distortion is relative to the voltage across the capacitor, which in my amplifier will be more than 400 times lower at 1kHz, and third harmonic can be expected to be proportional to the square of the signal level, so capacitor distortion relative to total input voltage at 1kHz could be something like -234dB.

Also keep in mind that a transmitter that cannot reproduce audio flatness would also be considered a form of distortion, since the resulting output audio frequency amplitude is a distortion of the original audio source.

Distortion product otoacoustic emissions were measured prior to and after music exposure. DPOAE amplitudes were measured at 9 different sound levels for 6 different f1/f2 frequency pairs, with tests conducted pre-music and at multiple post-music test times. Statistically reliable decreases in OAE amplitude were observed for the f2=3 kHz

Distortion occurs whenever the input/ output transfer function alters the waveform of a signal, discounting noise, interference, and amplification or at tenuation (Fig. 1). Distortion can be divided into two main categories [1]. a. Linear distortion: time and fre quency dependent characteristics of the amplitude and phase response
