The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods: Experiments in capturing sound on a recording medium for preservation and reproduction began in earnest during the Industrial Revolution of the 1800s.
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording . Acoustic analog recording is achieved by a ...
Timeline of audio formats. 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.
The phonautograph is the earliest known device for recording sound. Previously, tracings had been obtained of the sound-producing vibratory motions of tuning forks and other objects by physical contact with them, but not of actual sound waves as they propagated through air or other mediums. Invented by Frenchman Édouard-Léon Scott de ...
Digital audio. Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth.
Wire recording, also known as magnetic wire recording, was the first magnetic recording technology, an analog type of audio storage. It recorded sound signals on a thin steel wire using varying levels of magnetization. [1] [2] The first crude magnetic recorder was invented in 1898 by Valdemar Poulsen. The first magnetic recorder to be made ...
The history of modern multitrack audio recording using magnetic tape began in 1943 with the invention of stereo tape recording, which divided the recording head into two tracks. In 1948, Chicago's Armour Research Foundation announced that its staffer, physicist Marvin Camras, had produced a three-channel machine with "three parallel magnetic ...
Analog recording is a category of techniques used for the recording of analog signals. This enables later playback of the recorded analog audio . Analog audio recording began with mechanical systems such as the phonautograph and phonograph. [1] Later, electronic techniques such as wire [2] and tape recording [3] were developed.
