Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog formats.

An analog recording is one where the original sound signal is modulated onto another physical medium or substrate such as the groove of a gramophone disc or the iron oxide surface of a magnetic tape. A physical quality in the medium (e.g., the intensity of the magnetic field or the path of a record groove) is directly related, or analogous, to the physical properties of the original sound (e.g., the amplitude, phase, etc.)

A digital recording is produced by converting the physical properties of the original sound into digital information (called bits), which can then be stored and played back for reproduction. The accuracy of the conversion process depends on the sampling rate (how often the sound is sampled) and the sampling depth (how much information each sample contains). However, unlike analog recording which depends critically on the long-term durability of the fidelity of the waveforms recorded on the medium, the physical medium storing digital samples is essentially immaterial in playback of the encoded information so long as the individual bits can be recovered.
