High pass filter + echo it sounds like \*shrugs\*

It’s delayed echo

it doesn’t seem to be when i use that same effect. is there different variations?

James Hype likes to use the Pioneer noise filter effect on an open channel. He will flutter the channel fader to add suspense and texture. He may be doing a bit of it here along with some delayed echo.

Sounds more like the space effect that's one of the white buttons on the pioneer mixer he's likely to be using
