'''Dolby Spectral Recording''', commonly called '''Dolby SR''',is a sound format that incorporates a Dolby SR-Type noise reduction process. It is used in many aspects of analog recording but for the purposes of Sprocket School we will be talking exclusively about its use with 35mm stereo optical track prints and 35mm/70mm film prints with [[magnetic soundtracks]]. It is a 4 channel format- left, center, right and surround. | '''Dolby Spectral Recording''', commonly called '''Dolby SR''',is a sound format that incorporates a Dolby SR-Type noise reduction process.

It is important for projectionists to be able to distinguish between Dolby A and Dolby SR because different circuitry within the sound processor is required to play them back correctly. If you playback Dolby A as SR or vice versa, it will not sound correct. | It is important for projectionists to be able to distinguish between Dolby A and Dolby SR because different circuitry within the sound processor is required to play them back correctly.
