Talking machine made the first sound recording

The first sound recording in history took place in 1877 with the device developed by Thomas Edison (1847-1931) and called the "talking machine". Called the "phonograph", or more commonly, the "gramophone," this device recorded sound vibrations in traces on a tin foil wrapped in a rotating cylinder. To test the Edison machine, he first shouted "Hello" to the handset, and when he passed the foil under a needle attached to a diaphragm, he heard the same word repeat. This method of mechanical-acoustic recording lasted until the advent of electrical systems in 1920. Magnetic principles were used to develop tape recording systems. These systems achieved great commercial success with the introduction of magnetic plastic tape in 1935, followed by the use of microelectronics in the 1960s.
