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: -Bitrate, as the name implies, describes the rate at which bits are transferred from one location to another. It measures how much data is transmitted in a given amount of time. Bitrate is commonly measured in bits per second (bps), kilobits per second (Kbps), or megabits per second (Mbps).
