An analog signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal.
An audio power amplifier (or power amp) is an electronic amplifier that reproduces low-power electronic audio signals such as the signal from radio receiver or electric guitar pickup at a level that is strong enough for driving (or powering) loudspeakers or headphones.
A bandsaw (also written band saw) is a saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material.
A bass drum, or kick drum, is a large drum that produces a note of low definite or indefinite pitch.
Berliner Gramophone – its discs identified with an etched-in "E.
Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model.
Sound can be recorded and stored and played using either digital or analog techniques.
Denmark (Danmark), officially the Kingdom of Denmark,Kongeriget Danmark,.
In digital recording, audio signals picked up by a microphone or other transducer or video signals picked up by a camera or similar device are converted into a stream of discrete numbers, representing the changes over time in air pressure for audio, and chroma and luminance values for video, then recorded to a storage device.
In the context of digital signal processing (DSP), a digital signal is a discrete-time signal for which not only the time but also the amplitude has discrete values; in other words, its samples take on only values from a discrete set (a countable set that can be mapped one-to-one to a subset of integers).
In mathematics and in particular mathematical dynamics, discrete time and continuous time are two alternative frameworks within which to model variables that evolve over time.
Electrical polarity is a term used throughout industries and fields that involve electricity.
Emile Berliner (May 20, 1851 – August 3, 1929), originally Emil Berliner, was a German-born American inventor.
Fidelity is the quality of faithfulness or loyalty.
In physics, field strength means the magnitude of a vector-valued field (e.g., in volts per meter, V/m, for an electric field E).
Fritz Pfleumer (20 March 1881 in Salzburg – 29 August 1945 in Radebeul) was a German-Austrian engineer who invented magnetic tape for recording sound.
Experiments in capturing sound on a recording medium for preservation and reproduction began in earnest during the Industrial Revolution of the 1800s.
An instrument amplifier is an electronic device that converts the often barely audible or purely electronic signal of a musical instrument into an audible sound.
An integer (from the Latin ''integer'' meaning "whole")Integer 's first literal meaning in Latin is "untouched", from in ("not") plus tangere ("to touch").
Iron is a chemical element with symbol Fe (from ferrum) and atomic number 26.
In physics, specifically electromagnetism, the magnetic flux (often denoted or) through a surface is the surface integral of the normal component of the magnetic field B passing through that surface.
Magnetic storage or magnetic recording is the storage of data on a magnetized medium.
Magnetic tape is a medium for magnetic recording, made of a thin, magnetizable coating on a long, narrow strip of plastic film.
Magnetophon was the brand or model name of the pioneering reel-to-reel tape recorder developed by engineers of the German electronics company AEG in the 1930s, based on the magnetic tape invention by Fritz Pfleumer.
Mass production, also known as flow production or continuous production, is the production of large amounts of standardized products, including and especially on assembly lines.
Multitrack recording (MTR)—also known as multitracking, double tracking, or tracking—is a method of sound recording developed in 1955 that allows for the separate recording of multiple sound sources or of sound sources recorded at different times to create a cohesive whole.
Principle of the burn cutting Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S.) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively.
The phonautograph is the earliest known device for recording sound.
The phonograph is a device for the mechanical recording and reproduction of sound.
Phonograph cylinders are the earliest commercial medium for recording and reproducing sound.
A phonograph record (also known as a gramophone record, especially in British English, or record) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove.
Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set.
A recording head is the physical interface between a recording apparatus and a moving recording medium.
A recording studio is a specialized facility for sound recording, mixing, and audio production of instrumental or vocal musical performances, spoken words, and other sounds.
Soldering (AmE:, BrE), is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal.
In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.
Tape bias is the term for two techniques, AC bias and DC bias, that improve the fidelity of analogue tape recorders.
An audio tape recorder, tape deck, or tape machine is an audio storage device that records and plays back sounds, including articulated voices, usually using magnetic tape, either wound on a reel or in a cassette, for storage.
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman, who has been described as America's greatest inventor.
An audio format is a medium for sound recording and reproduction.
Valdemar Poulsen (23 November 1869 – 23 July 1942) was a Danish engineer who made significant contributions to early radio technology.
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.
A wind instrument is a musical instrument that contains some type of resonator (usually a tube), in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator.
Wire recording or magnetic wire recording was the first early magnetic recording technology, an analog type of audio storage in which a magnetic recording is made on thin steel wire.
