The “high” in high-fidelity refers to the level of comprehensiveness that allows you to examine usability questions in detail and make conclusions about the user behaviour. Although some high-end manufacturers do produce integrated systems, such products are generally disparaged by audiophiles, who prefer to build a system from separates (or components), often with each item from a different manufacturer specialising in a particular component. Audio professional Dr. Sean Olive of Harman International shares this view.. This integration is also available for high-end audio systems. ", Doug Schneider, editor of the online Soundstage network, refuted this position with two editorials in 2009. Definition of high-fidelity noun in Oxford Advanced Learner's Dictionary. What made you want to look up high fidelity? In the 2000s, modern hi-fi equipment can include signal sources such as digital audio tape (DAT), digital audio broadcasting (DAB) or HD Radio tuners. Streaming services typically have a modified dynamic range and possibly bit rates lower than audiophiles would be happy with. With the rise in popularity of home theater, however, multi-channel playback systems became popular, and many consumers were willing to tolerate the six to eight channels required in a home theater. There is now a push from certain streaming services to offer hi-fi services. Some multitrack recordings were made on optical sound film, which led to new advances used primarily by MGM (as early as 1937) and Twentieth Century Fox Film Corporation (as early as 1941). 1. He wanted to make a radio that would sound like he was listening to a live orchestra—that would achieve high fidelity to the original sound.

John Atkinson, current editor of Stereophile, stated that he once purchased a solid-state amplifier, the Quad 405, in 1978 after seeing the results from blind tests, but came to realize months later that "the magic was gone" until he replaced it with a tube amp. Audiophiles paid attention to technical characteristics and bought individual components, such as separate turntables, radio tuners, preamplifiers, power amplifiers and loudspeakers. Most people chose this as the best definition of high-fidelity: The electronic reproducti... See the dictionary meaning, pronunciation, and sentence examples.

In the world of the audiophile, however, the concept of high fidelity continued to refer to the goal of highly accurate sound reproduction and to the technological resources available for approaching that goal. Accessed 18 Dec. 2020. It is too expensive and frankly, too dangerous, to allow novice pilots to clock actual air time during flight school. The metal-oxide-semiconductor field-effect transistor (MOSFET) was adapted into a power MOSFET for audio by Jun-ichi Nishizawa at Tohoku University in 1974. If a listening test is done in such a way that the listener who is assessing the sound quality of a component or recording can see the components that are being used for the test (e.g., the same musical piece listened to through a tube power amplifier and a solid-state amplifier), then it is possible that the listener's pre-existing biases towards or against certain components or brands could affect their judgment.  CDs are capable of reproducing frequencies as low as 0 Hz and as high as 22.05 kHz, making them adequate for reproducing the frequency range that most humans can hear. Fidelity definition is - the quality or state of being faithful. The best example of a high-fidelity simulation is the flight simulator used by pilots in training.

High Fidelity is a musical with a book by David Lindsay-Abaire, lyrics by Amanda Green, and music by Tom Kitt. 'Nip it in the butt' or 'Nip it in the bud'. High-fidelity simulations strive to be as realistic as possible and include many elements, and also simulate the relationship or interactions between said elements.  The equipment must also provide no noticeable distortion of the signal or emphasis or de-emphasis of any frequency in this frequency range. That way, they could choose models of each component with the specifications that they desired. In this sense, a high-fidelity (sometimes referred as high-fi or hi-fi) prototype is a computer-based interactive representation of the product in its closest resemblance to the final design in terms of details and functionality.
