Wyoming protocol server that runs an external program to get microphone input.

The external program must stream raw PCM audio to its standard output, and its format must match the --rate, --width, and --channel arguments provided to the server. It's recommended that you only stream 16Khz 16-bit mono.

  --channels 1 \
