[amsat-bb] Audio file to .kss file - part 2

I got one step further, but haven't succeeded yet. I have some recorded 
telemetry from XW2D and the decoded program from DK3WN up and running on 
Linux using Wine. The telemetry program needs a .kss file to give some 
useful data.

This is how far I got:

1) run a PulseAudio null sink with this command: pactl 
load-module-null-sink sink-name=virtual-cable

2) play the audio with Audacity

3) run Dire Wolf

4) use pavucontrol to set the output (Playback tab) for Audicity and the 
input (Recording tab) for Dire Wolf to the null sink

5) Dire Wolf will now happily take the audio from Audacity, which you 
can see by checking the VU meter in pavucontrol

That's it.

Dire Wolf has the -l command line option to set a directory for log 
files, but no option to set the file name or any other hint on how to 
save data as a file. I know it is mainly used as a pipe to decoding 
programs, but what is the option to save to file? It is not always 
feasible to decode from a live signal, so what I try to achieve is to 
decode from recorded material. Any hints appreciated.
