Listed simply as Tier4, this short clip circulates on soundboards as a generic tier and upgrade cue, with no confirmed original game, show or creator attached to it. Its vague name is part of why it works so widely, fitting any ranking, loadout or progression system an editor is showing. Shared as a quick MP3 for streams, edits and group chats, it has become a reusable shorthand for reaching a new level, similar in spirit to a ding sound effect used to mark a completed step.
