Shortened form of reverberation, a type of echo.

From Reverberation.
Reverberation is the collection of reflected sounds from the surfaces in an enclosure like an auditorium. It is a desirable property of auditoriums to the extent that it helps to overcome the inverse square law dropoff of sound intensity in the enclosure. However, if it is excessive, it makes the sounds run together with loss of articulation - the sound becomes muddy, garbled. To quantitatively characterize the reverberation, the paramater called the reverberation time is used.
May also refer to an effects processor. The Yamaha Rev 5 is a reverb unit.
