Quadraphony, or quadrophonics, is a four-channel sound system. 🎧 It uses four speakers positioned in the corners of a room. This setup aims to recreate a more realistic and immersive sound field. Think of it like surround sound, but with a specific focus on four distinct audio channels. It was popular in the 1970s, but has been largely superseded by more advanced surround sound formats. It's like stereo, but amplified!
