About this project

Mic Drop is a PvP karaoke battle where two players sing the same song and the higher score wins the other person's solana. One player hosts on a laptop and the other joins by scanning a QR code on their phone. Both ante up SOL into an Anchor escrow program before the game starts. They take turns singing into the laptop mic, then the backend scores each take on lyrics timing (80%) and pitch accuracy (20%), and the user with the higher score gets the pot. The whole match is run by a live AI game show host powered by Gemini Live and ElevenLabs. It greets the room, asks each player if they're ready, starts turns by calling tools, then counts down the reveal on its own voice. ElevenLabs voices the host in a custom game show persona and generates all the custom sound effects. The backend runs pitch detection and speech to text for lyrics timing. The backend recomputes everything from the raw audio and sends the match results to Snowflake and feed a live leaderboard. We also implemented a "dance mode". It uses your laptop webcam and MediaPipe Pose to track your body in real time, showing a ghost skeleton of the choreography on screen so you know exactly what moves to hit. You're scored on how closely your joint angles match the reference frame by frame where the overall higher accuracy wins the pot.
