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 singer 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 finical 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 audio frequency recording and play back has gone through a series of revolutions. This provided society with some of the most important and red-letter audio thingmabobs such as the phonoautograph, telegraphone, and the 8-track tape system. The first catch 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 military personnel beings ear. It works by scratching representations of sound waves onto a typography cylinder covered in soot from an oil lamp. The energise that creates the etchings is moved by a diaphragm that vibrates in receipt to the sound.

The pros of this device were that it was the first device of its kind, it gave scientists a medium to set 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 youthful years, scientists have found a way to play phonoau tograms with good technology. The next mi! lestone 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 utilize a steal wire wrapped around a cylinder. The wire was swept over by an electromagnetic hug drug to record and playback.
