How does the Reverse effect work?

Reversing digital audio consists of reading the sequence of samples from end to beginning. This completely alters the attack transients of instruments, creating an ethereal and mysterious sound widely used in sound design.

Apply this effect to cymbals or pianos to create atmospheric transitions.
