I supposedly attempted to record myself speaking like a Demonic Scientist and used Audacity to put in the specific effect I know, which was a lower pitched version of the record playing at the same time as the normal pitched record.

Anyhow, I would appreciate if anyone remembers or rather knows the name of the effect, I searched all around Google to find the name.
Best Regards.

WOOF!
