Introduction
The process of capturing audio/sound data on a computer is known as sampling. Sound is usually sampled via a microphone which is connected to the computer's sound card.



ADC
Sound is an analog signal. The sound card has an analog-to-digital converter (ADC) which takes the analog sound signal and converts it to a digital signal.

Sampling
Capturing audio is known as sampling because the process "samples" part of the analog signal a number of times per second

Watch this video which explains how sampling works, and what the sample rate is
