[SOLVED] The flashback voice effect

[Theforgot3n1]

Hm, I tried using reverb, the echo, but it didn't sound close to what they do in the flashbacks.

A cool trick with reverb is to first reverse your vocal-track, apply the
reverb, then reverse it back to normal, gives a nice ghostly sound

What exactly did you mean? Should I have two tracks? One echoing with the reverse, and one normal?
Tried the two-tactic but it sounded just odd, not flashbackly.

Using Audacity.
