Audio Recording

Evolution of Audio Recording and Play Back The oldest cognise transcription of sound was new-fashionedly found and played by scientists at the Lawrence Berkeley National Laboratory in Berkeley, California. It was discovered to be a haunting ten second portion of a vocaliser performing Au Clair de la Lune. This arrangement predates what was previously believed to be the oldest sound recording (Thomas Edison singing Mary had a incident Lamb into his phonograph) by nearly two decades. Since the recording of Au Clair de la Lune was made in the late 1800s, the technology of speech sound recording and play back has gone through a series of revolutions. This provided society with some of the most important and haunting audio thingmabobs such as the phonoautograph, telegraphone, and the 8-track tape system. The first plait capable of recording sound was the phonoautograph. It was invented by the Frenchmen Leon Scott in 1857. He based the design of the device o n the anatomy of the charitable beings ear. It works by scratching representations of sound waves onto a opus cylinder covered in soot from an oil lamp. The evoke that creates the etchings is moved by a diaphragm that vibrates in response to the sound.

The pros of this device were that it was the first device of its kind, it gave scientists a medium to messiness sound waves in, and it was fairly accurately. Some negative qualities of the device were that it was fragile, and not actually capable of playing back the sound. Yet, in recent years, scientists have found a way to play phonoautograms with respectable technology. The next milesto! ne in the technology of audio recording and playback was the telegraphone. It was the first practical device for magnetic recording and reproduction. It was invented by the Danish telephone engineer Valdemar Poulsen and patented in 1898. The telegraphone engross a steal wire wrapped around a cylinder. The wire was swept over by an electromagnetic project to record and playback.
