Distortion occurs when the transfer function F is more complicated than this. If F is a linear function, for instance a filter whose gain and/or delay varies with frequency, the signal suffers linear distortion. Linear distortion does not introduce new frequency components to a signal but does alter the balance of existing ones.
The outer distortion can also be characterized by means of an inequality similar to that given in the two-dimensional case. If Ω is an open set in R n, then a function ƒ ∈ W 1,1 loc (Ω,R n) has finite distortion if its Jacobian is locally integrable and does not change sign, and there is a measurable function K O (the outer distortion ...
The DS-1 was the first ever distortion guitar effect pedal manufactured by Boss An auditory example of the distortion effect with the clean signal shown first.. Distortion and overdrive are forms of audio signal processing used to alter the sound of amplified electric musical instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone.
Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping may cause it to output power in excess of its power rating .
A waveshaper is an audio effect that changes an audio signal by mapping an input signal to the output signal by applying a fixed or variable mathematical function, called the shaping function or transfer function, to the input signal (the term shaping function is preferred to avoid confusion with the transfer function from systems theory). [3]
Clipping is a form of distortion that limits a signal once it exceeds a threshold. Clipping may occur when a signal is recorded by a sensor that has constraints on the range of data it can measure, it can occur when a signal is digitized , or it can occur any other time an analog or digital signal is transformed, particularly in the presence of ...
A Bitcrusher is an audio effect that produces distortion by reducing the resolution or bandwidth of digital audio data. The resulting quantization noise may produce a "warmer" sound impression, or a harsh one, depending on the amount of reduction.
Distortion synthesis is a group of sound synthesis techniques which modify existing sounds to produce more complex sounds (or timbres), usually by using non-linear circuits or mathematics. [ 1 ] While some synthesis methods achieve sonic complexity by using many oscillators , distortion methods create a frequency spectrum which has many more ...
