because the audio files are highly compressed whilst retaining a high level of sound quality. For example a raw audio file of 36MB will become a high quality MP3 file of 3.6MB. You can squeeze around 10 hours of audio in MP3 format onto a CD (which usually only stores around one hour of non-compressed audio).

Nyquist Rate. The Nyquist rate is a concept derived from digital sampling theory which states that to accurately represent a particular frequency, the signal must be sampled at twice the rate of that frequency. For example, to create an accurate digital representation of 10 kHz, you would need to use a minimum 20 kHz sampling rate.
