Also to know is, what is the difference between Dolby Digital and Dolby Surround?
Dolby offers two different 7.1 surround versions. Dolby Digital Plus is the “lossy” version, which still involves data compression and takes up less space on a Blu-ray disc. Dolby TrueHD, on the other hand, is lossless. Since no compression is involved, Dolby TrueHD is intended to be identical to the studio master.
Beside above, is stereo better than Dolby Digital? Stereo has 2 channels. Dolby 5.1 has 6 channels. A stereo system can't do that, you would just hear a bang from all speakers. If you don't have 6 or more speakers wired up to a surround sound system, you should just stick with stereo.
Keeping this in view, what is a Dolby sound system?
Dolby Stereo is a sound format made by Dolby Laboratories. There are two basic Dolby Stereo systems: the Dolby SVA (stereo variable-area) system used with optical sound tracks on 35mm film, and Dolby Stereo 70mm which refers to Dolby noise reduction on 6-channel magnetic soundtracks on 70mm prints.
