In common usage, a "stereo" is a two-channel sound reproduction system, and a "stereo recording" is a two-channel recording. This is a cause for much confusion, since five-channel home theater systems are not popularly described as "stereo". It is thus worth noting that most film soundtracks are not recorded using stereo techniques, so while they are capable of stereo reproduction, most home theater systems rarely are called upon to do this. Synchronization was achieved by making the recordings in the form of three motion-picture soundtracks recorded on a single piece of film. Because of dynamic range limitations, volume compression was used, with a fourth track being used to regulate volume expansion.

The Dolby noise reduction system of the 1970s was a far more sophisticated version of a basically similar technique. The volume compression and expansion were not fully automatic, but were designed to allow manual studio "enhancement", i.e., the artistic adjustment of overall volume and the relative volume of each track. Most two-channel recordings are stereo recordings only in this weaker sense. Pop music, in particular, is usually recorded using close milking techniques, which artificially separates signals into several tracks. The separate tracks are then mixed into a two-channel recording which often bears little or no resemblance to the actual physical and spatial relationship of the musicians at the time of the original performance.

Indeed, it is not uncommon for different tracks of the same song to be recorded at different times, and even in different studios, and then mixed into a final two-channel recording for commercial release. Classical music recordings are a notable exception.
