5.1 surround sound - Wikipedia
Sound systems that use 5 speakers and one subwoofer Most common loudspeaker configuration for 5.1; used by Dolby Digital , SDDS , DTS , THX , and Dolby Pro Logic II . The white square in the center of the diagram depicts the low-frequency speaker. Each black square depicts a loudspeaker. The center speaker in the top line of the diagram is used for dialogue. The left and right speakers on either side of the center speaker are used to create stereo sound for music and other sound effects in the film. The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres . [1] It uses five full bandwidth channels and one low-frequency effects channel (the "point one"). [2] Dolby Digital , Dolby Pro Logic II , DTS , SDDS , and THX are all common 5.1 systems. 5.1 is also the standard surround sound audio component of digital broadcast and music. [3] All 5.1 systems use the same speaker channels and configuration, having a Front Left ( FL ) and Front Right ( FR ), a Center Channel ( CNT ), two surround channels (Surround Left - SL and Surround Right - SR ) and the low-frequency effects ( SW ) channel designed for a subwoofer . [4] [5] History [ edit ] A prototype for five-channel surround sound, then dubbed "quintaphonic sound", was used in the 1975 film Tommy . [6] 5.1 dates back to 1976, [7] when Dolby Labs modified the track usage of the six analogue magnetic soundtracks on Todd-AO 70 mm film prints . The Dolby application of optical matrix encoding in 1976 (released on the film Logan's Run ) did not use split surrounds, and thus was not 5.1. Dolby first used split surrounds with 70 mm film, notably in 1979 with Apocalypse Now . Instead of the five screen channels and one surround channel of the Todd-AO format, Dolby Stereo 70 mm Six Track provided three screen channels, two high-passed surround channels and a low-frequency surround channel monophonically blended with the two surround channels. A system of digital 5.1 surround sound was also used in 1987 at the Parisian cabaret the Moulin Rouge , created by French engineer Dominique Bertrand. To achieve such a system in 1985, a dedicated mixing console had to be designed in cooperation with Solid State Logic , based on their 5000 series, and dedicated speakers in cooperation with APG. [8] The console included ABCDEF channels: respectively, A left, B right, C centre, D left rear, E right rear, F bass. The same engineer had already developed a similar 3.1 system in 1973, for use at the official International Summit of Francophone States in Dakar . [ citation needed ] Digital sound and the 5.1 format were introduced in 1990, by Kodak and Optical Radiation Corporation, with releases of Days of Thunder and The Doors using the CDS ( Cinema Digital Sound ) format. When digital sound was applied to 35 mm release prints, with Batman Returns in 1

Dafür braucht man zuhause spezielle Lautsprecher bei denen auch der Sound von hinten kommen kann.
