Reverb, short for reverberation, is an audio effect that simulates the persistence of sound in a space after the original sound has stopped. It occurs when sound waves reflect off surfaces like walls, floors, and ceilings, creating a series of echoes that blend together. This effect is commonly used in music production and live sound to add depth and richness to recordings. In music, reverb can enhance vocals and instruments, making them sound more natural and immersive. Different types of reverb, such as hall, plate, and spring, can be used to create various atmospheres, from the spaciousness of a concert hall to the warmth of a small room.
