Discord launched in 2015 as a voice and text platform built for gamers, and its interface sounds quickly became familiar to anyone using voice channels. The join chime was designed to alert people in a channel that someone new had arrived, without interrupting the conversation. As Discord grew into a mainstream tool for communities, streamers and creators, the sound moved beyond the app and began appearing in videos, streams and memes as shorthand for someone entering a chat. Its brevity and clarity keep it useful today, in gaming and reaction content where a new arrival needs to be signalled instantly.
