How does stereo audio differ from mono audio?

Stereo audio is defined by the use of two channels, which allows for a more immersive and realistic sound experience compared to mono audio. In stereo sound, separate audio tracks can be played through the left and right channels. This separation creates a spatial effect, enabling listeners to perceive sounds coming from different directions. For instance, in a musical track, vocals might be placed in the center with instruments spread out across the stereo field.

This contrasts with mono audio, which relies on a single channel, thus blending all sounds into one track without spatial differentiation. The addition of two channels in stereo audio enhances the listening experience by simulating a more natural auditory environment and providing depth to the sound, making it richer and more dynamic.
