Haunted Audio

In the video below, Harry Frank and Aharon Rabinowitz go tag team for a tutorial in sound design, creating scary audio (backwards reverb) as heard in Poltergeist. Aharon covers how to create the effect using audio software, while Harry shows you how to recreate that effect in After Effects.

Whoops, no previews even low res, but there's links all around.
