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.

multimon-ng 用法示例

从rtl_fm以raw导入(-t raw),添加POCSAG512,POCSAG1200,POCSAG2400和SCOPE模块(-a POCSAG512 -a POCSAG1200 -a POCSAG2400 -a SCOPE),解码字符模式(-f alpha),从标准输入读取(/dev/stdin):

:~# rtl_fm -f 149.614M -s 22050 -p -19
multimon-ng -t raw -a POCSAG512 -a POCSAG1200 -a POCSAG2400 -a SCOPE -f alpha /dev/stdin
