Reverb Tail

A ‘Reverb Tail’ is the decay of the reverb when the dry, direct sound signal has stopped. 

Reverb itself can be broken into 2 essential components: early reflections (the sound of the room that almost melds into the original signal), and late reflections (the tail).

Sometimes, reverb tails are added to dialogue when edits have to be made that cause the line to abruptly end. In this situation the reverb tail helps place the line in the world of the movie.

You can hear an example of a long reverb tail here: Soundsnap: Epacridal.wav
