High fidelity or hi-fi reproduction is a term used by home stereo listeners and home audio Home audio, essentially, refers to any audio electronics intended for home use, such as home stereos and surround sound receivers, which are becoming the most popular piece of home audio equipment. Home audio generally does not include such standard equipment such as built-in television speakers, but rather accessory equipment, which may be enthusiasts (audiophiles An audiophile, from Latin audio "I hear" and Greek philos "loving," is a hobbyist who seeks high-quality audio reproduction via the use of non-mass-produced high-end audio electronics) to refer to high-quality reproduction of sound Sound recording and reproduction is an electrical or mechanical inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a small microphone diaphragm that or images Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion that are very faithful to the original performance.[1] Ideally, high-fidelity equipment has minimal amounts of noise In common use, the word noise means any unwanted sound. In both analog and digital electronics, noise is an unwanted perturbation to a wanted signal; it is called noise as a generalisation of the audible noise heard when listening to a weak radio transmission. Signal noise is heard as acoustic noise if played through a loudspeaker; it manifests as and distortion A distortion is the alteration of the original shape of an object, image, sound, waveform or other form of information or representation. Distortion is usually unwanted. In some fields, distortion is desirable, such as electric guitar (where distortion is often induced purposely with the amplifier or an electronic effect to achieve an aggressive and an accurate frequency response Frequency response is the measure of any system's output spectrum in response to an input signal. In the audible range it is usually referred to in connection with electronic amplifiers, microphones and loudspeakers. Radio spectrum frequency response can refer to measurements of coaxial cables, category cables, video switchers and wireless as set out in 1973 by the German Deutsches Institut für Normung Deutsches Institut für Normung e.V. is the German national organization for standardization and is that country's ISO member body (DIN) standard DIN 45500. This standard was well intentioned, but only mildly successful in defining 'high-fidelity'. DIN 45 500 approval provided audio equipment buyers with reassurance that their equipment was capable of good quality reproduction. In theory, only stereo equipment that met the standard could bear the words 'hi-fi', but in practice, the term was widely misapplied to audio products that did not remotely approach the DIN basis specifications.
By the 1990s, the term hi-fi for expensive high-quality home-audio electronics was largely replaced with high-end audio High-end audio is a term used to describe a class of consumer home audio equipment marketed to audio enthusiasts on the basis of high price or quality, and esoteric or novel sound reproduction technologies. High-end audio can refer simply to the price, to the build quality of the components, or to the subjective or objective quality of sound.[citation needed]
