A Flutter Android application that integrates multimon-ng for decoding various digital radio protocols from audio input on Android devices.

This project combines:

• Flutter - Cross-platform UI framework
• Multimon-ng - Multi-protocol digital signal decoder
• TCP Audio Input - Receives audio data via TCP from SDR++ or similar applications

Note: This is primarily an audio decoding tool. It accepts TCP audio input from SDR++ and does NOT include integrated RTL-SDR support. Use SDR++ or another SDR application to handle radio tuning and demodulation, then stream the audio to this app via TCP.

• TCP audio input from SDR++ or compatible applications
• Real-time signal decoding
• Support for multiple protocols (POCSAG, FLEX, DTMF, ZVEI, EAS, etc.)
• Simple UI for message display
• Audio processing via multimon-ng

cd multimon_android
flutter pub get
flutter build apk

1. Configure SDR++ to output audio via TCP
2. Launch the app and connect to the TCP audio stream
3. View decoded messages in the list
