Whois & Analysis for analogplanet.com

An audiophile is a person enthusiastic about high-fidelity sound reproduction.

Audiophile values may be applied at all stages of music reproduction: the initial audio recording, the production process, and the playback, which is usually in a home setting.

The phonograph is a device invented in 1877 for the mechanical recording and reproduction of sound.

In its later forms it is also called a gramophone (as a trademark since 1887, as a generic name since c.

1900).

The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record".

To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound.

In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones.

In later electric phonographs (also known as record players (since 1940s) or, most recently, turntables), the motions of the stylus are converted into an analogous electrical signal by a transducer, then converted back into sound by a loudspeaker.

Analog recording (Greek, ana is "according to" and logos "relationship") is a technique used for the recording of analog signals which, among many possibilities, allows analog audio and analog video for later playback.

A preamplifier (preamp) is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise tolerant and strong enough for further processing.

Without this, the final signal would be noisy or distorted.

They are typically used to amplify signals from analog sensors.

Because of this, the preamplifier is often placed close to the sensor to reduce the effects of noise and interference.

A gramophone record (phonograph record in the US), commonly known as a vinyl record or simply vinyl or record, is an analog sound storage medium in the form of a flat polyvinyl chloride (previously shellac) disc with an inscribed, modulated spiral groove.

The groove usually starts near the periphery and ends near the center of the disc.
