Fidelity is therefore a measure of the realism of a model or simulation. [4] Simulation fidelity has also been described in the past as "degree of similarity". [5] In quantum mechanics and optics, [6] the fidelity of a field is calculated as an overlap integral of the field of interest with a reference or target field.
Early digital audio machines had disappointing results, with digital converters introducing errors that the ear could detect. [36] Record companies released their first LPs based on digital audio masters in the late 1970s. CDs became available in the early 1980s.

Image fidelity, often referred to as the ability to discriminate between two images [1] or how closely the image represents the real source distribution. [2] Different from image quality, which is often referred to as the subject preference for one image over another, image fidelity represents to the ability of a process to render an image accurately, without any visible distortion or ...

Randall contributed guest vocals to "The Snow Falls" from The Baldwin Brothers' album The Return of the Golden Rhodes credited as 'The Train' and "Rest Easy" from Half's debut album Here Lies credited as 'Wrecked Train'.
Contrast, also known as gamma, is the slope of the tone reproduction curve in a log-log space. High contrast usually involves loss of dynamic range — loss of detail, or clipping, in highlights or shadows. Color accuracy is an important but ambiguous image quality factor. Many viewers prefer enhanced color saturation; the most accurate color ...
