Chirp Pong: Two-Player Game Demonstrates Audio-Based Network Communication

1 reports1 sources10/15/2026 updated

Current overview (not historical)

AI overview

Simon Willison showcased a two‑player Pong game that uses chirps—short audio bursts—to enable network communication between two phones. Leveraging Claude Opus 5.5 Extra within Claude Code, the demo proves that a static HTML page can transmit game state through the browser’s microphone API, adding graphics and gameplay variations for a more engaging experience. The experiment highlights the feasibility of low‑latency, audio‑only networking for simple web games, illustrating how existing AI models and web APIs can be combined to create novel interactive experiences without traditional internet connections.

    Report first recorded Oct 16, 04:46

    Simon Willison successfully built a two-player competitive Pong-like game running in static HTML on two separate phones. The game state is transmitted via audio noises (chirps) interpreted by the web microphone API, demonstrating the feasibility of audio-based networking in this environment.
