Chirp: Sound-Based Data Transfer App

Chirp is an application that transmits data via sound. It uses a simple encoding scheme to convert text into audio frequencies, which are played through speakers and picked up by a microphone. Features include real-time frequency visualization, text-to-sound transmission, and sound-to-text reception, using distinctive start and end signatures. Built with Node.js, React, TypeScript, and Vite, leveraging the Web Audio API for audio processing.
