Reverberation is the persistence of sound in a space after the original sound has stopped. When you clap your hands in a large room, the sound waves bounce off the walls, ceiling, and floor, creating echoes. This effect can make the sound seem richer and fuller, as it lingers in the air for a moment before fading away. In music, reverberation is often used to enhance recordings, giving them a sense of depth and atmosphere. Instruments and vocals can sound more vibrant and alive when mixed with reverb, making it a popular tool in studios and live performances.
