There are many ways to create and present a soundtrack. The simplest method used in the first sound films is 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), 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 “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 will use it in a conventional sense. There are exceptional microphones that record surround sound (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.
You must overcome the clutter if you are looking for a surround sound system.
Here is an essential guide to surround sound that I hope will help you. Surround sound is an adequate way to boost your big-screen TV’s entertainment value.
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 is the number of subwoofers, and the number after is the number of speakers. 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), meaning sounds can be placed in the room for superb surround effects.
DTS is slightly better than Dolby Digital because the sound is less compressed, which makes it 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 room’s rear.
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.
