	'''Dolby A''' is a noise reduction process created by Dolby Laboratories. It is used in many aspects of analog recording but for the purposes of Sprocket School we will be talking exclusively about ~~it's~~ use with 35mm and 70mm film prints. Dolby A can be used to refer to the noise reduction process itself, or to the four channel sound format – left, center, right and surround. It was in use from approximately 1975 to 1986, when it was largely replaced by [[Dolby SR]].		'''Dolby A''' is a noise reduction process created by Dolby Laboratories.
