Dolby surround sound system is very important for cinematic sound effects. At first Dolby surround sound system is only used to produce the effects in cinema. Star Wars had used the system to create better sound effects that are real time and of quality impact. However, with the innovation in the sound system industry, Dolby surround sound system can already be applied at home.
Dolby surround sound system can work perfectly with 5.1 surround system. The speakers can localize the production of sound effects giving the entire sound a cinematic impact. For soundtracks that are encoded with more sound localizations, 7.1 surround systems can be best used. Dolby surround sound system has truly made a tremendous impact to the aspect of sound experience at home.
It is hard for 5.1 surround system or even the 7.1 to totally preserve all sound effects that are produced in movies and music. Engineers have been looking for ways to enhance the capability of the sound system to produce sounds that are real time and with proper effects. However, certain localization of sound may prove to waste some of the effects.
To answer the problem, Dolby surround sound system aims to preserve all sound waves and optimize them as they travel to the speakers. With out any loss of the sound waves, you will heart all sound effects that are created during the production of movies and songs.
On the other hand, low frequency speaker or the subwoofer is designed for bass and bass-based sound effects. With 5.1 surround system, some of the low frequency sounds are lost during production or playback. With the best of Dolby surround sound system, bass and bass-based sound effects are preserved and processed to give a more realistic impact to the sound system results
