“Critical Synthesis”, “Cosmic Sound” or simply “Cool Stuff”!
You can call it like you want but essentially it does not change. This is the high quality, 100% exclusively produced and absolutely ready for your project sound effect. It can be use in a game, movie, cartoon, audiobook or something else, preferably on the alien/cosmic theme, but maybe you can find better use for it.
This sound also included in Critical Synthesis Sound Pack
