Dolby A is a 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 vs. Dolby SR
Dolby A is difficult to distinguish from Dolby SR by sight. Here are some tips on telling them apart:
- Many studio films made between 1975 and 1985 will have Dolby A tracks.
- Some (but not all) films with Dolby A tracks will display the word "Dolby" - or "Dolby Stereo" rather than "Dolby SR" - with the Dolby logo in the end credits.
- Some (but not all) films with Dolby A tracks will display the words "Stereo" on the edges of the film leader.
- A Dolby A track played in Dolby SR will usually sound harsh or blown out
