Stereo sound is a method of audio reproduction that uses two or more channels to create a sense of space and direction in sound. This technique mimics how humans naturally hear, allowing listeners to perceive sounds coming from different directions. Stereo sound enhances the listening experience in music, movies, and video games by providing a more immersive environment. In a typical stereo setup, speakers are placed apart to create a left and right channel. This arrangement allows for a richer sound experience, as instruments and voices can be positioned within the sound field. Devices like stereo speakers and headphones are commonly used to deliver stereo sound.
