Okay so, I've been listening to a genre of music called sigilkore recently, which is essentially plugg rap music but with more of a demonic type of sound, and it also mixes glitchcore and hyperpop to make it what it is. But anyway, in this type of music the rappers tend to litter their music with sound effects of all kinds. So I was listening to one of my favorite sigilkore artists, islurwhenitalk, and I'm usually able to identify the sound effects used in these type of songs but I've been searching for the one used in this song and I can't find it anywhere. Song link below:

It's the sound effect right at the start. I've heard it been called a teleportation sound effect, a space sound effect, a warping sound effect, a ufo sound effect, but I can't find it at all. Please someone assist me in finding this. Thanks in advance.

Yeah, it's a sine wave effect.
I think it's from the old Zero-G Datafile CDs
