Ambiance -- Low level sounds that set a mood or suggest the character of a particular place. Analog vs. digital -- The difference between analog and digital sound is explained best in terms of the analog and digital soundtracks on the Dolby Digital print shown in Figure 1. Figure 1 The width of the analog soundtrack varies in a way that is directly analogous to the varying soundwaves of the original sound. All analog formats have an equivalent varying parameter, such as the strength of the magnetic field on recording tape, or the side-to-side swings of the groove on a phonograph record. When played back, the varying width of the track is translated to a varying electrical voltage which ultimately causes the theatre's loudspeakers cones to move back and forth to recreate the original sound. With a digital optical soundtrack, points along the soundwaves of the original sound are assigned a numeric (or digital) value, which are represented as tiny dots on the track.

Dolby Is a Deep Company That Owns Many Technologies. Keeping the Terminology Straight Is Challenging
Dolby is a deep company that owns many technologies. Keeping the terminology straight is challenging. Here is my version: Dolby Surround (LCRS-->Lt/Rt-->files/tape/broadcast-->LCRS) 4:2:4 matrix process only. The mono surround channel is bandwidth limited between 100hz and 7khz. The term was originally used to mean Dolby Stereo, but now the term is used for non-film delivery formats. See Dolby Pro Logic Dolby Stereo (LCRS-->LtRt-->Dolby A encode-->OpticalTrack-->Dolby A decode-- >LCRS) 4:2:4 matrix described above with Dolby A type noise reduction. Dolby A is no longer favored, instead use Dolby SR. Dolby SR (LCRS-->LtRt-->Dolby SR encode-->OpticalTrack-->Dolby SR decode-- >LCRS) 4:2:4 matrix described above with Dolby SR type noise reduction. This is the same as Dolby Stereo except that the optical track is encoded with SR instead of A type noise reduction. This format is still used for surround audio from film optical and as the backup track for Dolby Digital. The terms Dolby SR and Dolby Stereo are often interchanged, incorrectly. Dolby Digital a.k.a. AC-3 5.1-->AC-3 data stream-->5.1 The compressed data stream supports up to 5 full bandwidth plus one low frequency effects channel. It is designed for film, broadcast, and DVD final audio delivery. It is NOT considered "editable", which means you cannot just "punch in" on the data stream without consequences. This is the digital audio part of Dolby SR-D and Digitial Cinema. Dolby SR-D is a dual-stream audio delivery system printed on the film, with a Dolby SR optical track and blocks of bits printed between sprocket holes that, when reconstructed, form the AC-3 digital audio stream.

R59-1998 Dolby Stereo, Dolby SR and Dolby Surround in a TV
EBU Technical Recommendation R59-1998 Page 1 of 2 EBU Technical Recommendation R59-1998 Dolby* Stereo*, Dolby SR* and Dolby Surround* in a Television Environment EBU Committee First Issued Revised Re-issued PMC 1989 1997,1998 Keywords: Keywords: Audio in television, Film Film programmes More and more 35-mm feature films are made in multichannel sound and are available in a version with a matrixed surround sound track using the Dolby Stereo or more recently the Dolby SR system. Broadcasting these sound tracks on television would offer viewers with suitable equipment the benefit of an enhanced experience. However, to provide other viewers with different receiving equipment with the best possible reception in mono, stereo and surround forms, and requires the correct technological procedures before transmission. To meet this requirement, the EBU recommends that the following practices are adopted when Dolby Stereo or Dolby SR films are processed in the studio: · Whenever possible, a stereo magnetic master or magnetic soundtrack should be used for sound reproduction. However, the most common source of sound accompaniment on film is the stereo optical soundtrack on a positive copy. It is recommended to clean such a copy before transfer. · As a principle, avoid reproducing stereo optical sound track from a negative copy. Such a track should always be converted into a positive form. · A Dolby Stereo optical track should always be reproduced using a stereo optical pickup. If only a mono signal is required, it should be derived as a down mix from the two-channel Dolby Stereo signals. · Films marked “Dolby Stereo” should be reproduced using an expander of the Dolby A noise reduction system.

The History of Sound in the Cinema
A fascinating article by Dion Hanson of Dolby Laboratories, Chairman of the BKSTS Cinema Technology Committee, based on the 1997 Annual BKSTS Bernard Happé Memorial Lecture which Dion presented under the title Fantastic Formats. Bernard Happé was a Member, Fellow, and Past- president of the BKSTS and a member of the Technicolor team who played a great part in the development of film formats, including 70mm. Fantastic Formats is a visual experience giving the audience a chance to see some of the older formats they have only read about. Dion says that it is impossible to recreate in print, but this article is based upon the presentation, and provides useful reminders for the older members who can remember some of the developments taking place, and gives an excellent history lesson for those who are newer to the cinema sound scene. Thanks are due to Dolby who kindly sponsored the Bernard Happé Lecture.

And what the audience hears today, both in the cinema and at home, is very much the result of a continuing effort to improve film sound originally undertaken by Dolby Laboratories more than twenty years ago. Indeed, the evolution of motion picture sound over the past two decades is, in great part, that of Dolby film sound technologies. Optical Sound The photographic or "optical" soundtrack was the first method of putting sound on film, and today it remains the most popular. An opaque area adjacent to the picture contains narrow, clear tracks that vary in width with variations in the sound (Figure 1). As the film is played, a narrow beam of light from an exciter lamp in the projector's soundhead shines through the moving tracks. Variations in the width of the clear tracks cause a varying amount of light to fall on a solar cell, which converts the light to a similarly varying electrical signal.

Introduction
Surround Sound System Introduction We are now entering the Third Age of reproduced sound. The monophonic era was the First Age, which lasted from the Edison’s invention of the phonograph in 1877 until the 1950s. during those times, the goal was simply to reproduce the timbre of the original sound. No attempts were made to reproduce directional properties or spatial realism. The stereo era was the Second Age. It was based on the inventions from the 1930s, reached the public in the mid-‘50s, and has provided great listening pleasure for four decades. Stereo improved the reproduction of timbre and added two dimensions of space: the left – right spread of performers across a stage and a set of acoustic cues that allow listeners to perceive a front-to-back dimension. In two-channel stereo, this realism is based on fragile sonic cues. In most ordinary two-speaker stereo systems, these subtle cues can easily be lost, causing the playback to sound flat and uninvolved. Multichannel surround systems, on the other hand, can provide this involving presence in a way that is robust, reliable and consistent. The purpose of this seminar is to explore the advances and technologies of surround sound in the consumer market. Surround Sound System 1. How we hear 3-D Sound? Human hearing is binaural (based on two ears), yet we have the ability to locate sound spatially. That is, we can determine where a sound is coming from, and in most cases, from how far away. In addition, humans can distinguish multiple sound sources in relation to the surrounding environment.
