Stereo sound

Definition

Stereo sound is a method of sound reproduction that uses two or more independent audio channels to create a sense of depth and directionality in sound. This technique enhances the listening experience by simulating how human ears perceive sounds in real life, allowing for a more immersive audio experience in film and media. It plays a crucial role in sound design by enabling filmmakers to position sounds within a three-dimensional space, enhancing storytelling through auditory cues.
