What is surround sound?
There are many ways to make and present recordings of music. Mono is the simplest method and the oldest used in the world of audio playback. Mono means that all the sound is recorded to one audio track or tracks (e.g. , a single looped spiral groove in a record, or a single track on a tape), which is then played through a single speaker
Two-channel sound is played on speakers on both sides of the listener, which is what we usually call stereo. But that's not entirely accurate, as "stereo" actually refers to the broader "multi-channel" recording. (Binaural sound formats are now common in home stereo receivers, televisions, and FM radio.) The simplest form of binaural recording, also known as "binaural recording," involves using two microphones instead of two human microphones at the recording site. The ears "get" it. When you listen to the playback of these two channels on the speakers, it recreates the "immersive" experience for you
"Surround sound" recording takes this idea a step further, adding more audio channels so sound comes from three or more directions. While the term "surround sound" technically refers to a specific multichannel system designed by Dolby Laboratories, it is more commonly used as a general term for multichannel sound systems such as theaters and home theaters.
