Place it as the final beat of a study or progress edit, after the last answer or result appears. Follow it with a Bell Ding for a second reward, or put a Vine Boom before it when a failed attempt turns into a win.
About this sound
The short cue marks the close of a Duolingo lesson, with a clean, upbeat chime that rings once and settles quickly. It gives a small, satisfying lift, turning a finished exercise into a clear win rather than a quiet stopping point. The cue comes from Duolingo, the language-learning app, where it plays when a learner completes a lesson.
