multimon-ng is a command-line decoder for digital transmission modes such as POCSAG, FLEX, AFSK/FSK, DTMF, ZVEI, EAS, and Morse code, succeeding the original multimon. It accepts live audio (PulseAudio), WAV files, or piped raw samples from tools like rtl_fm and sox.

Use cases

• decode POCSAG pager messages from an RTL-SDR dongle
• decode FLEX pager traffic from a wav recording
• demodulate AFSK1200 data from radio audio
• decode DTMF tones from an audio file
• decode EAS emergency alert broadcasts
• pipe rtl_fm output into a digital mode decoder
• decode Morse code (CW) from audio

When to choose

• you need to decode pager, FSK, or tone signaling protocols from SDR or recorded audio
• you want a scriptable CLI decoder that fits into pipelines with rtl_fm or sox
• you need broad protocol coverage including POCSAG, FLEX, DTMF, and EAS in one tool

When to avoid

• you need a GUI-based signal analysis suite
• you want to decode modern digital voice modes like DMR, P25, or D-STAR
• you need software-defined radio reception itself rather than decoding of demodulated audio
