From smooth sound to stored data

Analogue sound wave sampled at regular intervals, then rounded to quantised levels with example binary values shown

Real-world sound is analogue, so its amplitude changes smoothly over time. Computers store data in binary, so they cannot keep the whole continuous wave directly.
