How do I create a Dalek voice in Audition?

[David Goodwin]

There are various tutorials around the web but the one’s I’ve seen always result in something that just sounds like normal voice distorted a bit, nothing like the 2005+ era Daleks with the ring modulator.

An actual ring modulator machine is very expensive. I have seen (or rather, heard) some very good recreations on some videos but have no idea how they achieved it.
