Surround sound processing is a technology that enhances audio experiences by creating a three-dimensional sound environment. It uses multiple speakers placed around a listener to simulate sounds coming from various directions, making the audio feel more immersive. This technique is commonly used in home theaters, cinemas, and gaming systems. The process involves encoding audio signals into different channels, such as 5.1 surround sound or 7.1 surround sound, which correspond to specific speaker placements. Surround sound processing can also be found in Dolby Atmos and DTS:X, which add height channels for an even more realistic sound experience.
