Usage: multimon-ng [file] [file] [file] ...
If no [file] is given, input will be read from your default sound
hardware. A filename of "-" denotes standard input.
-t <type> : input file type (any other type than raw requires sox)
-a <demod> : add demodulator
-s <demod> : subtract demodulator
-c : remove all demodulators (must be added with -a <demod>)
-q : quiet
-v <level> : level of verbosity (for example '-v 10')
-f <mode> : forces POCSAG data decoding as <mode> (<mode> can be 'numeric', 'alpha' and 'skyper')
-h : this help
-A : APRS mode (TNC2 text output)
-m : mute SoX warnings
-r : call SoX in repeatable mode (e.g. random seed for dithering)
Raw input requires one channel, 16 bit, signed integer (platform-native)
samples at the demodulator's input sampling rate, which is
usually 22050 kHz. Raw input is assumed and required if piped input is used.

Would send a comment that looks like
