Place it at the decision point in the middle of your edit, just after the options are shown and before the winner is revealed. Follow it with a cheer for a happy pick, or a game show buzzer for a rejected choice, so the sequence reads as a complete judging moment.
About this sound
This is a short, sharp button-style sound lasting about five seconds, built around a single dramatic cue that signals selection and approval. It feels tense, exciting and slightly over the top, turning an ordinary pick into a talent-show moment. It comes from The Voice, the television singing competition where coaches press a button and turn their chairs to choose a contestant.
