DRM Cast

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! 🚀 ---- 개발자 연락처 : (주)알고코리아 양천구 목동중앙본로18길 31, B층 02호(목동, 이신빌라) 양천구, 서울특별시 07975 South Korea 408-81-78604 제2008-광주동구-83호 본인직접진행
