Have you ever thought of sending messages using sound? Not your voice, but actual encoded sound waves? Meet Rattlegram, a fascinating new way to transceive short UTF-8 text messages using COFDMTV-encoded audio signals.
Developed by the team at aicodix GmbH, Rattlegram brings together advanced digital signal processing and clever open-source software to let your phone do something truly unique: send and receive messages through sound, much like how old-school modems used to—but way more modern and mobile-friendly.
What Is Rattlegram?
Rattlegram is an innovative app that turns your smartphone into a two-way audio communicator for text. It uses a method called COFDMTV (Coded Orthogonal Frequency Division Multiplexing with Time Variation) to encode text into sound. Your phone’s microphone and speaker become the only tools needed to “hear” or “speak” messages.
You can try it out yourself on both iOS and Android:
