As the name suggests, Analog to Digital converters take raw analog electrical signals and convert them into digital information. Microphones convert sound energy into electrical currents, which can travel throughout a computer, but electrical currents can't be stored as information. The ADC is charged with the duty of changing that current into digital data that the computer can access and manipulate.
The current that comes from the microphone will vary in voltage based on the audio. When it travels to the ADC, it takes samples of the current. A lot of ADCs take 44, samples every second, while others take even more. The ADC measures each sample and, based on the voltage, assign a sequence of binary digits to it.
The number of digits per sample corresponds to the number of output pins on the ADC. These sequences of binary digits are then compiled into a digital file which can be stored. ADCs have multiple input and output pins, usually 8, 16, 24, or 32 pins.
