Chirp: Sound-based Data Transfer
This application allows you to transmit and receive data through sound. It uses a simple encoding scheme to convert text into audio frequencies, which can be played through your speakers and picked up by a microphone.
Features
Real-time frequency visualization of audio input
Send messages by converting text to sound
Receive messages by listening to sound and decoding it back to text
Distinctive start and end signatures to mark transmissions
How It Works
Text Encoding: Each character is mapped to a unique frequency Transmission: The app plays a start signature, followed by the encoded text, and ends with an end signature Reception: The app listens for frequencies, looks for the start signature, decodes the frequencies back to text, and stops at the end signature Visualization: Real-time visualization of the frequency spectrum lets you see the data being transmitted and received
