Explanation:
Detailed explanation-1: -An analogue sound wave is picked up by a microphone and sent to an Analogue to Digital (ADC) converter in the form of analogue electrical signals. The ADC converts the electrical signals into digital values which can be stored on a computer. Once in a digital format you can edit sounds with programs such as audacity.
Detailed explanation-2: -All audio that is recorded or played through a computer system is digital, but all audio that is played out of a speaker system is analog.
