Now it seems so easy … But 160 years ago it wasn't. Many don't know what the first human voice recording was. Registration takes only ten seconds. It is an interpretation of the French folk song "Au Clair de la Lune". This month is 160 years old. Do you want to hear it Go to this link.
Test one, two …
It dates from 1860. It was manufactured by the French bookseller and writer Édouard-Léon Scott de Martinville. He is also the inventor of the phonoautograph, the first sound recording device.
It is the first known human voice recording before the first recording by Thomas Edison in 1877. The phonoautograph was created by recording soot-coated paper and was only developed to record sounds. It could later be reproduced by American scientists using a "virtual pen" to read the lines.
The recording was believed to be the voice of a woman or a teenager. However, studies from 2009 indicated that the playback speed was too high. It was actually Scott's own voice. This is because, according to firstsounds.org, it is easier to determine the time when the same person produces the sound.
A historical invention
The phonoautograph was the first device that could record sound. The sound was recorded in the form of a line with slight deviations on a carrier consisting of a "smoked" cylinder with a lamp. Although it was later impossible to reproduce. Nevertheless, this artifact was used to demonstrate that a sound recording was possible. It has also been used to experiment in the field of hearing.
The traction was already achieved through the vibration movements that make noise. But never from real sound waves that spread in the air or in any other way.
With this invention, the sound waves were transcribed. Waves or other deviations in the form of a line on paper or blackened smoked glass. It was intended as a laboratory instrument for acoustic examinations. It could also be used to visually examine and measure the amplitude and waveforms of voice and other sounds. He was able to determine the frequency of a musical tone by comparing it to a reference frequency recorded at the same time. Only after the development of the phonograph was it understood that the wave recorded by the phonoautograph was exactly a sound recording that only needed a suitable playback medium to reproduce itself.
One can say that this first recording of the human voice was a song for the future.
