Trautonium
The Trautonium is an electronic synthesizer invented in 1930 by Friedrich Trautwein in Berlin at the Musikhochschule's music and radio lab, the Rundfunkversuchstelle. Soon afterwards Oskar Sala joined him, continuing development until Sala's death in 2002. Description Instead of a keyboard, its manual is made of a resistor wire over a metal plate, which is pressed to create a sound. Expressive playing was possible with this wire by gliding on it, creating vibrato with small movements. Volume was controlled by the pressure of the finger on the wire and board. The first Trautoniums were marketed by Telefunken from 1933 until 1935 (200 were made). The sounds were at first produced by neon-tube relaxation oscillators Example of a similar early neon keyboard invention by Winston E. Kock (later, thyratrons, then transistors), which produced sawtooth-like waveforms. The pitch was determined by the position at which the performer pressed the resistive wire into contact with the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oskar Sala
Oskar Sala (18 July 1910 – 26 February 2002) was a German composer and a pioneer of electronic music. He played an instrument called the Trautonium, an early form of electronic synthesizer. Early life Sala was born in Greiz, Thuringia, Germany. He studied piano and organ during his youth, performing classical piano concerts as a teenager. In 1929, he moved to Berlin to study piano and composition with composer and violist Paul Hindemith at the Berlin Conservatory. He also followed the experiments of Dr. Friedrich Trautwein, at the school's laboratory, learning to play with Trautwein's pioneer electronic instrument, the Trautonium. On 20 June 1930 Sala and Paul Hindemith gave a public performance at the Berliner Musikhochschule Hall called “Neue Musik Berlin 1930″ to introduce the Trautonium. Later Sala toured Germany with the Trautonium; in 1931 he was the soloist in a performance of Hindemith's Concert for Trautonium with String Quartet. He also soloed in the debut of Hinde ...

The Birds (film)
''The Birds'' is a 1963 American natural horror-thriller film produced and directed by Alfred Hitchcock. Loosely based on the 1952 short story of the same name by Daphne du Maurier, it focuses on a series of sudden and unexplained violent bird attacks on the people of Bodega Bay, California, over the course of a few days. The film stars Rod Taylor and Tippi Hedren in her screen debut, alongside Jessica Tandy, Suzanne Pleshette, and Veronica Cartwright. The screenplay is by Evan Hunter, who was told by Hitchcock to develop new characters and a more elaborate plot while keeping du Maurier's title and concept of unexplained bird attacks. At the 36th Academy Awards, Ub Iwerks was nominated for Best Special Effects for his work on the film. The award, however, went to the only other nominee, Emil Kosa Jr. for ''Cleopatra''. In 2016, ''The Birds'' was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress, and selected for pre ...

Friedrich Trautwein
Friedrich Trautwein ( August 11, 1888 in Würzburg – December 20, 1956 in Düsseldorf ) was a German engineer. Trautwein developed the Trautonium and is considered a pioneer of electronic music in Germany. Life As a child, Friedrich Trautwein learned to play the organ in church. He studied electrical engineering at the Technical University of Karlsruhe, followed by law and physics in Berlin and Heidelberg. In 1906, he joined the '' Teutonia fraternity'' in Karlsruhe. He passed the traineeship examination for the higher postal service in 1911. During WWI, he was a lieutenant in charge of a mounted radio squad. After passing the assessor exam in 1919, he went on to study physics in Heidelberg and Karlsruhe, where he earned his doctorate in engineering. He began working as a postal clerk at the ''Telegraphentechnisches Reichsamt'' the following year. In this capacity, he was involved in the establishment of the first German radio station, which was based in Berlin's Vox bu ...

Synthesizer
A synthesizer (also spelled synthesiser) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI. Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II Sound Synthesizer, RCA Mark II, which was controlled with Punched card, punch cards and used hundreds of vacuum tubes. The Moog synthesizer, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concertos
A concerto (; plural ''concertos'', or ''concerti'' from the Italian plural) is, from the late Baroque era, mostly understood as an instrumental composition, written for one or more soloists accompanied by an orchestra or other ensemble. The typical three- movement structure, a slow movement (e.g., lento or adagio) preceded and followed by fast movements (e.g. presto or allegro), became a standard from the early 18th century. The concerto originated as a genre of vocal music in the late 16th century: the instrumental variant appeared around a century later, when Italians such as Giuseppe Torelli started to publish their concertos. A few decades later, Venetian composers, such as Antonio Vivaldi, had written hundreds of violin concertos, while also producing solo concertos for other instruments such as a cello or a woodwind instrument, and concerti grossi for a group of soloists. The first keyboard concertos, such as George Frideric Handel's organ concertos and Johann Sebastia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Generator
A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. Theory There are several circuits used for noise generation. For example, temperature-controlled resistors, temperature-limited vacuum diodes, zener diodes, and gas discharge tubes. A source that can be switched on and off ("gated") is beneficial for some test methods. Noise generators usually rely on a fundamental noise process such as thermal noise or shot noise. Thermal noise generator Thermal noise can be a fundamental standard. A resistor at a certain temperature has a thermal noise associated with it. A noise generator might have two resistors at different temperatures and switch between the two resistors. The resulting output power is low. (For a 1 kΩ resistor at room temperature and a 10 kHz bandwidth, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formant
In speech science and phonetics, a formant is the broad spectral maximum that results from an acoustic resonance of the human vocal tract. In acoustics, a formant is usually defined as a broad peak, or local maximum, in the spectrum. For harmonic sounds, with this definition, the formant frequency is sometimes taken as that of the harmonic that is most augmented by a resonance. The difference between these two definitions resides in whether "formants" characterise the production mechanisms of a sound or the produced sound itself. In practice, the frequency of a spectral peak differs slightly from the associated resonance frequency, except when, by luck, harmonics are aligned with the resonance frequency. A room can be said to have formants characteristic of that particular room, due to its resonances, i.e., to the way sound reflects from its walls and objects. Room formants of this nature reinforce themselves by emphasizing specific frequencies and absorbing others, as exploited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandpass Filter
A band-pass filter or bandpass filter (BPF) is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. Description In electronics and signal processing, a filter is usually a two-port circuit or device which removes frequency components of a signal (an alternating voltage or current). A band-pass filter allows through components in a specified band of frequencies, called its ''passband'' but blocks components with frequencies above or below this band. This contrasts with a high-pass filter, which allows through components with frequencies above a specific frequency, and a low-pass filter, which allows through components with frequencies below a specific frequency. In digital signal processing, in which signals represented by digital numbers are processed by computer programs, a band-pass filter is a computer algorithm that performs the same function. The term band-pass filter is also used for optical filters, she ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
