This is slightly wrong. I used to do it this way, but the better way is: Reverse > Reverb > Cut > ReverseTheRavestyler wrote:with that "ahhhh" u mean that reverse vocal effect maybe ?
if u yes just add a reverb to the vocal cut out the reverb and reverse it
if u want to do it with a Letter (like "T" from "This" for example) just cut out that letter > reverb > cut > Reverse
if u mean something else explain better
so that the reverb ends up more similar to the forward direction sample when reversed.
