SOUND SAMPLING is performed by a small
and cheap hardware device called a
sampler and this simply converts the
Analogue audio data into Digital
data suitable for use by the computer.
ANALOGUE data can vary infinitely
and is so not defined in precise
steps but as a voltage.
DIGITAL data is represented by
either ON or OFF , HIGH and LOW in
digital electronics or 1 and 0 in
computing. When strings of these 1s
and 0s are strung together they can
form numbers.
