sound is made up of waves in the form of vibrations in the air, and can be detected by the human ear. Using magnets analoque technology takes sound waves and turns them into electrical pulses. When a metal conductor is moved inside the magnetic field an electric current is produced in that wire.
Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.
In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.
