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 ...
Prior to this point, the earliest known record of a human voice was thought to be an 1877 phonograph recording by Thomas Edison. [7] [14] The phonautograph would play a role in the development of the gramophone, whose inventor, Emile Berliner, worked with the phonautograph in the course of developing his own device. [15]
This technology, the basis for almost all commercial recording from the 1950s to the 1980s, was developed in the 1930s by German audio engineers who also rediscovered the principle of AC biasing (first used in the 1920s for wire recorders), which dramatically improved the frequency response of tape recordings.
An audio format is a medium for sound recording and reproduction.The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
Ludwig Blattner, also known as Louis Blattner, [2] was a pioneer of early magnetic sound recording, licensing a steel wire-based design from German inventor Dr. Kurt Stille, [citation needed] and enhancing it to use steel tape instead of wire, thereby creating an early form of tape recorder. This device was marketed as the Blattnerphone. [3]
A humpback whale has stunned scientists with a journey that spanned three oceans and more than 8,000 miles, setting the record for the longest known migration between breeding grounds.
