I was wondering if anyone knows how to get the effect that is used in a lot of death metal on the vocals. A great example of the is "Dead by Dawn" by Deicide, the sounds of the growling and screams in the beginning. It's sort of a phasing type sound that I have heard on many Deicide songs and also some Bloodbath songs like "The Soulcollector". It kind of makes the voice sound like you are riding past it in a tunnel. If you know what I'm talking about and know how to get this effect let me know.
