Ring-and-spring microphones, such as this Western Electric microphone, were common during the electrical age of sound recording c. 1925–45.. The second wave of sound recording history was ushered in by the introduction of Western Electric's integrated system of electrical microphones, electronic signal amplifiers and electromechanical recorders, which was adopted by major US record labels in ...
The device's true significance in the history of recorded sound was not fully realized prior to March 2008, when it was discovered and resurrected in a Paris patent office by First Sounds, an informal collaborative of American audio historians, recording engineers, and sound archivists founded to make the earliest sound recordings available to ...
Players typically describe recorder pitches by the number of nodes in the air column. Notes with a single node are in the first register, notes with two nodes in the second register, etc. As the number of nodes in the tube increases, the number of notes a player can produce in a given register decreases because of the physical constraint of the ...
The Encyclopedia of Recorded Sound is a reference work that, among other things, describes the history of sound recordings, from November 1877 when Edison developed the first model of a cylinder phonograph, and earlier, in 1857, when Léon Scott de Martinville invented the phonautograph. [1]
Between the invention of the phonograph in 1877 and the first commercial digital recordings in the early 1970s, arguably the most important milestone in the history of sound recording was the introduction of what was then called electrical recording, in which a microphone was used to convert the sound into an electrical signal that was ...
By 1881 the Volta associates had success in improving an Edison tinfoil machine to some extent. Wax was put in the grooves of the heavy iron cylinder, and no tinfoil was used. The basic distinction between the Edison's first phonograph patent, and the Bell and [Charles Sumner] Tainter patent of 1886 was the method of recording. Edison's method ...
The first wire recorder was the Telegraphone invented by Valdemar Poulsen in the late 1890s. Wire recorders for law and office dictation and telephone recording were made almost continuously by various companies (mainly the American Telegraphone Company) through the 1920s and 1930s.
The first Western system of functional names for the musical notes was introduced by Guido of Arezzo (c. 991 – after 1033), using the beginning syllables of the first six musical lines of the Latin hymn Ut queant laxis. The original sequence was Ut Re Mi Fa Sol La, where each verse started a scale note higher. "Ut" later became "Do".
