The Complete Guide to Surround Sound

Surround sound is an immersive audio experience that creates sound from multiple directions, angles, and heights, making you feel like you’re in the middle of the action. Whether overseeing a movie, recreating a video game, or hearing to music, surround sound can enhance your experience and make it more realistic.


The Complete Guide to Surround Sound is a comprehensive guide to the technology and products behind surround sound. In this direction, we will take a more intimate glimpse at how surround sound works, the different types of surround sound formats, the various components that make up a surround sound system, and how to set up and configure a surround sound system for the best possible audio experience.

First, surround sound format was developed:

Surround sound technology has come a long way since its inception. The first surround sound format developed in the 1930s was “Fantasound.” It was used in the movie “Fantasia” and required a multi-channel audio setup with multiple speakers in a theatre. Surround sound technology is much more advanced and can be found in many different forms, including movie theatres, home theatres, and even headphones.


The most common surround sound format is 5.1 channel surround sound, which consists of five full-range speakers (left, center, right, left surround, and right surround) and one subwoofer. The subwoofer reproduces low-frequency sounds, such as bass and explosions, while the other five speakers reproduce higher-frequency sounds.

Another popular surround sound format is 7.1 channel surround sound, which adds two additional speakers (left rear and right rear) for even more immersive audio.

Dolby Atmos and DTS: X

In complement to traditional surround sound formats, there are also newer surround sound technologies such as Dolby Atmos and DTS: X. These technologies use multiple speakers placed in different locations in a room to create a 3D soundstage, where sounds can be heard from above, in addition to the traditional left, right, and center channels.

This creates a more realistic and immersive audio experience, as the sound can be heard from all around the room, making it feel like it is coming from all directions.


You will need critical components to set up a surround sound system. The first component is an AV receiver or preamp, which is responsible for processing the audio signal and sending it to the speakers. You will also need a set of speakers, including a combination of floor-standing speakers, bookshelf speakers, and in-wall or in-ceiling speakers. A subwoofer is typically included in a surround sound system, reproducing low-frequency sounds.

Correct locations:

When configuring your surround sound system, it is vital to place the speakers in the correct locations. The center channel speaker should be placed in the center of the room, directly in front of the listener. The left and right speakers should be positioned at an equal distance from the listener and angled toward the listener. The surround speakers should be placed behind the listener and turned towards the listener.

The subwoofer can be put anywhere in the space, but it should be near a wall or corner for the best bass response.


Another important aspect of setting up a surround sound system is room tuning. This involves adjusting the speakers and the room’s acoustics to optimize the goexcellentuality. This can include using bass traps, diffusers, and absorbers to control the room’s sound reflections and adjust the speaker’s position and orientation. A speaker’s status and orientation can significantly affect good quality.


It is also essential to mention that the room’s layout, size, and type of furniture can significantly affect it.

What About Other Surround Sound Variations?

One such variation is DTS:X, similar to Dolby Atmos in that it uses an object-based audio system and allows for sounds to be heard from above. DTS:X also allows for a more flexible speaker setup and can be found on some home theatre systems and in some movie theatres.

Another variation is Auro-3D, a surround sound format that adds a height dimension to the audio experience. It uses a unique speaker layout, with speakers placed at the front, rear, and above the listener, to create a more immersive audio experience. Auro-3D is mainly used in commercial cinemas and high-end home theatre systems.

Lastly, IMAX Enhanced is a new surround sound format that combines the latest surround sound technologies, such as DTS:X, with the latest video technologies, such as 4K HDR. IMAX Enhanced is optimized for IMAX theatres, but it can also be found on home theatre systems and TVs.

All these surround sound variations are aimed to enhance the user’s audio experience and offer a more immersive and realistic experience. It’s important to note that not all these technologies are widely adopted, yet they provide a unique approach to surround sound technology.
