Stereo sound

Definition

Stereo sound is an audio reproduction system that uses two or more independent audio channels to create a sense of space and dimension in sound. By simulating how humans naturally hear sounds from different directions, stereo sound enhances the listening experience, making it more immersive and realistic. This technique is vital in various applications, especially in film and music, where spatial audio cues help convey emotions and storytelling.
