About this app

This app is an app that enables DRM30 signal transmission (Tx) and reception (Rx) using the audio input and output of an Android smartphone.

🔹 Rx (Receive Mode)
- Receives DRM30 signals from an audio input device and decodes them using the OPUS codec
- Outputs audio and displays received data

🔹 Tx (Transmit Mode)
- Captures voice input from the smartphone’s microphone and encodes it into a DRM30 signal
- Allows attaching photos, documents, and other data for transmission via an audio output device

🔹Additional Features & Requirements
- Easily switch between Rx and Tx modes (cannot run simultaneously)
- Supports wired audio input/output by default
- For wireless transmission, a device supporting DRM30 signal with 10kHz bandwidth is required
- Due to the lack of built-in audio ports on modern smartphones, an external USB-C audio device is needed

Experience seamless DRM30 signal transmission and reception with this app! 🚀
