History of the audio recording and now

Long before the sound was first recorded, the music was recorded, first by a musical code, then by instruments (for example, string music boxes, during which a mechanism spins a tooth, pulls its teeth, and then recreates a melody). The reproduction of automatic music dates back to the 9th century, when the Bane Mass brothers first invented a known instrument, in this case, a hydraulic (water powered) element that reads interchangeable cylinders. Charles B. According to Fowler, this "... cylinder with pegs raised above the surface was an essential device for the mechanical delivery and reproduction of music until the second half of the 19th century." The Bane Mass brothers also invented an automatic flute player, which seems to be the first programmable machine.

Sound recording and reproduction is the entertainment of sound waves such as electrical, mechanical, electronic or digital inscription and speaking voice, song, music or sound effects. The two main classes of sound recording technology are analog recording and digital recording.

The analog sound is recorded using a microphone diaphragm (in which a pencil cuts grooves on a disk), which detects changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of sound waves in the average type of phonograph record. In the magnetic tape recorder, sound waves vibrate and alternate the microphone's diaphragm, which is then converted into an electromagnetic switchable magnetic flux, which sounds like magnetized parts on a plastic tape with a magnet coating on it. Analog playback is a reverse process that produces acoustic sound waves with changes in atmospheric pressure by means of a large speaker diaphragm.

Digital recording and converting the analog sound signal taken by the playback microphone into a digital format using the sampling trick. This allows audio data to be stored and transmitted over a wide range of media. The digital signal transmits audio as a series of binary numbers (zeros and one) to the audio signal's amplitude at equal time intervals, capable of transmitting all sounds at a sampling rate. Multiply the digital audio signal and convert it to analog during playback before connecting to the speaker to provide sound.

Before the sound recording event, there were mechanical systems such as string music boxes and, later, playback pianos to play the coding and music.
