Audio I/O App for DRM30 Signal Transmission and Reception
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! 🚀
