Discord launched in 2015 as a voice and text platform for gamers, and its interface sounds quickly became familiar to millions of daily users. The undeafen chime is part of that built in set, played when a user who had deafened themselves restores both microphone and speaker audio. As Discord moved beyond gaming into general communities, clips of its join, mute and undeafen sounds spread across YouTube edits, TikTok videos and soundboards alongside other call sounds like the bass boost discord call effect. Its lasting use comes from instant recognition among regular callers.
