Dolby Surround was the earliest consumer version of Dolby's multichannel analog film sound decoding format Dolby Stereo introduced to the public in 1982 during the time home video recording formats (such as Betamax and VHS) were earlier introducing Stereo and HiFi capability.

The term Dolby Surround is used as not to confuse theater stereo which is at least four channels of audio with home stereo which is two.

The Dolby Surround decoding technology was updated during the mid-1980s and re-named Dolby Pro Logic in 1987. The terms Dolby Stereo, Dolby Surround and LtRt are used to describe soundtracks that are matrix-encoded using this technique.
