What is Surround Sound?

What is Surround Sound

There are many ways to create and present a soundtrack. The simplest method and that used in the first sound films is called mono or merely mono.

Mono means that all sound is recorded on an audio track or channel (for example, a spiral track on a track or a magnetic track on a tape), which is usually reproduced on the speaker.

Two-channel recordings in which sound is output from the speakers on either side of the listener are often called stereotypes.

This is not entirely true, as true stereo (or stereo) refers to a broader range of multichannel recordings.

Dual-channel sound is the standard format for home music systems, TV shows, and FM radio. 

The most unaffected two-channel records, called binaural recordings, are produced with two microphones installed at a live event (for example, a concert) to replace two human ears.

When you pay attention to these two channels on different speakers, you recreate the experience of participating in the event.

Green recordings take this idea a step further, adding audio channels so that sound comes from three or more directions.

Although the term “surround sound” technically refers to specific multichannel systems created by Dolby Laboratories, it is more frequently used as a generic term for multichannel and home theater sound systems.

In this article, we are going to use it in a conventional sense. There are exceptional microphones that will record surround sound (recording sound in three or more directions), but this is not a standard way to create surround sound.

Almost all of the film’s surround-sound recordings were made in a mixing studio.

Editors and sound mixers take different audio recordings (dialogues recorded on a film set, sound effects recorded in a dubbing studio or generated on a computer, sharing music) and decide on the channel or channel to define their own.

Basic Types of Surround Sound

Surround sound can be very confusing with all the different channel configurations and associated technologies.

If you are looking for a surround sound system, you have to overcome the clutter.

Here is an essential guide to surround sound that I hope will help you. Surround sound is one of the adequate ways to boost the entertainment value of your big-screen TV.
The main species

The three significant types of surround sound are 5.1, 6.1, and 7.1 channels.

The first number of orderly speakers and the number after is the number of subwoofers. So 5.1 applies to 5 speakers and a subwoofer; 6.1 has six speakers and a subwoofer, etc.

There are other permutations, like 7.2, which means seven speakers and two subwoofers (which you might need in a large room).

Another feature of many 7.2 receivers is that they can surround sound in one place and stereo sound in another.

5.1 Surround Channels

5.1 channel surround sound is the most common home theater setup, as it is the easiest of the three, will work in most rooms, is an excellent job in creating a true surround sound experience, and is generally less expensive.

The two most popular types of surround sound in 5.1 systems are Dolby Digital and DTS.

Dolby Digital is a common phenomenon in cinemas. Each channel is discrete, i.e., independent of the other channels), which means that sounds can be placed in the room for superb surround effects.

DTS is a little better than Dolby Digital in that the sound is less compressed, which makes it a little more precise and realistic.

6.1 Surround Channels

6.1-channel surround sound offers a slightly more impressive surround sound effect than the 5.1-channel system as there is an additional discreet center channel at the rear of the room.

It has three front and rear speakers in addition to the subwoofer. The audio electronics types for 6.1 systems are generally DTS-ES, Dolby Digital EX, and THX Surround EX. Most 6.1 surround receivers will support multiple audio formats.

DTS again has less compression for slightly more transparent sound, but both forms provide an incredible experience.

7.1 Surround Channels

7.1-channel systems are configured with three speakers on the front, one on each side and two on the rear for a surround effect. 7.1 audio formats are perhaps the most talented, with Dolby TrueHD and DTS-HD Master Audio.

Both are newer formats with lossless, uncompressed surround sound and can be identical to the original studio recording. Blu-ray discs support this full lossless audio format for 7.1 systems.
