So i am working on a drop, and i have the synths that i want to use and i tihink they sound good, but something is missing, there is this kind of background sound that i hear and i dont know what it is exactly or what they are doing to accomplish it. i have a sub bass under my High Pitch Hits (scream bass), but if you listen to the scream bass on this song, there is this extra sound there, anyone know where i can get some information on what he is doing, or does anyone know what hes doing, and have other examples?

Thanks. also if anyone knows how to make some of those scream basses that would cool too man.

Parallel distortion/birtcrushing and a shit ton of white noise.

Some tips when making a drop:

Have a background arp.
Have a vocal, "heur", "yo" skanking.
Use loads of crashes.
