This sound is known online as the Shroud donation sound, a label tied to streamer culture and especially gaming clips shared around 2020. It spread through reposted highlights, short edits, and meme compilations where creators wanted the feel of a real livestream alert without needing a full stream setup. Its staying power comes from how instantly it signals Twitch-style interaction: the audience reads it as a donation, interruption, or sudden attention shift, even in very short videos.
