The left side of the stage corresponds to an imaginary line drawn from the left side of your left speaker straight back through your front wall. (Surround sound recreates this same performance stage, but it adds the ability to place sounds to the sides and behind the listener.) The front edge of the stereo soundstage corresponds to an imaginary line drawn between the fronts of your two speakers. Stereo creates a sound-field that, more or less, is shaped like a performance stage that is situated in front of you–as if you’re sitting in a theater. Stereo systems require a front left and front right speaker. The alternative to surround sound is stereo sound.

Most avid action movie fans get surround sound. drama) happening behind you sounds fun, surround sound may be for you. side wall and rear wall speakers), again to immerse you in the sonic environment that is suggested by the scene. In a movie scene with a couple strolling through a city park, for instance, the surround system might play traffic and bird noises in the surround speakers (i.e. Such blatant use of surround sound happens frequently in action movies, while in dramas its application is subtle. To the listener, it sounds like the arrow travels from the front of the room to the rear of the room. That is, if a character shoots an arrow into the camera, the whooshing sound of the arrow traveling towards the camera and then continuing behind the camera will be handled by the surround system. The goal of surrounding you with sound in all directions is to immerse you in the sonic environment that is suggested by what you’re seeing on the screen. One or two pair of speakers are installed along the side and/or rear walls. the viewer’s left) and a speaker to the right of the screen. These include a center speaker, which is above or below the screen, and then a speaker to the left (i.e. Three speakers are installed along the wall with the TV–this wall is referred to as the front wall. Typically, a surround sound system uses five speakers and a subwoofer, and when the room is long, seven speakers and a subwoofer. Very little music is recorded in surround sound. (This is used to creepy effect in the movie, The Others, where footsteps can be heard as if coming from the room above you.) Most all modern movie soundtracks are recorded for surround sound. Surround sound is designed to provide a sound-field in front of you, to your sides, and behind you. Stereo is their other option, and so I explain that as well. Anyway, it’s only natural that clients assume surround sound is what they’ll be buying. The first time I heard it I thought that there was baby in the movie theater. There is an organ like sound that ramps up in volume and contains a low rumble, there is the sound of glass breaking, and the one I find most impressive, the baby crying. THX, a company involved in establishing surround sound standards, runs strikingly bold and clear sound clips coming from all around the theater, or maybe just to the side or just behind you. They get bombarded with advertising touting surround sound, and it gets promoted very well in the movie theaters right before the picture starts. Surround sound is simply what’s been sold to them. After probing further I realize that they don’t know what surround sound is. Often I’ll meet clients who say that they want surround sound.
