Sound is a wave. To store sound in a computer, waves of air pressure are converted into voltage via a microphone and sampled with an analog-to-digital converter where the output is stored as a one-dimensional array of numbers. Simply saying, an audio file is just an array of amplitudes sampled with a certain rate known as the sampling rate and it has a sample rate, number of channels of sound, and precision (bit depth) as meta-property.
