What are the differences between stereo and mono sound systems, and how do they affect the audio quality of a recording?

Stereo sound systems use two separate audio channels to create a sense of space and direction in the sound, while mono sound systems use a single audio channel. Stereo systems provide a more immersive and realistic listening experience by separating different sounds into left and right channels. This can enhance the audio quality of a recording by creating a sense of depth and dimension. Mono systems, on the other hand, combine all sounds into a single channel, which can result in a more basic and flat audio experience with less spatial separation.
