The Physical Architecture of Sound
Music is physically carved into vinyl records as a continuous, microscopic spiral groove. When a needle follows this track, the vibrations create the exact sounds you hear.
Think of a record as a physical map of a sound wave. As the needle bumps along the textured walls of the groove, it vibrates to mimic the original audio pressure. It is essentially a 3D sculpture of music that you can touch. Remarkably, this analog technology remains the only format where you can visually see the music encoded on the disc.
