Documentation
Generate a wav (mp3) file for packet data to differentiate data and ACK. Consider this module as a bonus module - the use may limited.
-h, --help show this help message and exit -v LOGLEVEL, --verbose=LOGLEVEL set the loglevel (info, debug, warning, error) -f CONNECTIONS, --data-flow=CONNECTIONS specify the number of relevant ID's -m MODE, --mode=MODE display packets or bytes in flight (default packets) -o FILENAME, --outfile=FILENAME name of the generated wav file (default: packets.wav) -i DURATION_MIN, --duration-min=DURATION_MIN minimum length of sound sample in seconds -a DURATION_MAX, --duration-max=DURATION_MAX maximum length of sound sample in seconds -b LINK_BANDWIDTH, --bandwidth=LINK_BANDWIDTH netto bandwith of channel in bit/s (default 100MB) -c ACCELERATOR, --accelerator=ACCELERATOR accelerator, 0.0001 times faster is default -r CUT_GAP_PERIODES, --cut-gap-periodes=CUT_GAP_PERIODES crop longer silence periodes to this, default 0.5
