Wave-share [https://ggerganov.github.io/wave-share] [https://github.com/ggerganov/wave-share] Serverless, peer-to-peer, local file sharing through sound A proof-of-concept for WebRTC signaling using sound. Works with all devices that have microphone + speakers. Runs in the browser. Nearby devices negotiate the WebRTC connection by exchanging the necessary Session Description Protocol (SDP) data via a sequence of audio tones. Upon successful negotiation, a local WebRTC connection is established between the browsers allowing data to be exchanged via LAN.
