console convert pcap to wav: not easily possible; use the WireShark GUI to do

Posted by jpluimers on 2021/12/01

Wanting a simple way on the console to convert a .pcap file to a .wav file, I searched for [Wayback] console convert pcap to wav – Google Search.

The reason is that [Wayback] fritzcap (written in Python) sometimes crashes while doing the conversion of a phone recording, so then only the .pcap file is available. I still want to figure this out, but given my health situation, I might not be able to in time.

If anyone with Python experience can help, I have failing capture files lying around, and the fritzcap command-line does support decoding [Wayback/Archive.is]:

# feature/re-add_documentation(+0/-0)* ± python fritzcap.py --help
usage: fritzcap.py [-h] [-v] [-c] [-d [file [file ...]]] [-m] [-p password]
                   [-u username] [-s] [--config_file path_to_file]
                   [--logging_config path_to_file] [--box_name host_or_IP]
                   [--call_service_port port] [--login_not_required]
                   [--protocol protocol] [--cap_folder path_pattern]
                   [--cap_file file_pattern] [--cap_interface cap_interface]
                   [--after_capture_time time_in_seconds]
                   [--decode_workers_count int]

...
main arguments:
...
  -d [file [file ...]], --decode_files [file [file ...]]
                        the list of captured files to decode. All the new
                        captures files will be decode automatically if the
                        --capture switch is set. Read the files from the
                        standard input if the list of files is empty and there
                        is no capture work.

Back to other tooling for decoding VoIPcap/pcap files

Too bad there are no easy solutions. You can use the WireShark GUI to do this, which is OK for infrequent conversions.

Here were some of the results leading me to that conclusion:
