Dolby Surround is an audio technology designed to create an immersive sound experience for listeners. It uses multiple audio channels to simulate a three-dimensional sound environment, allowing sounds to come from various directions. This enhances the overall experience when watching movies or listening to music. Originally developed in the 1980s, Dolby Surround has evolved into more advanced formats like Dolby Digital and Dolby Atmos. These technologies provide clearer sound and more precise audio placement, making it feel as if the sound is coming from all around you, rather than just from the front speakers.
