Using jack_capture to copy rosegarden audio output as
a *.wav file
This guide is valid this day, tomorrow it could be totally obsolete,
you have been warned.
After having tried every which way to use ffmpeg to screencast audio
with video or audio only but always without success as far
as audio goes, I downloaded jack_capture and bingo!
I didn't see any installation instructions so I just did this:
Thence, with jack runing, I enter
- Got jack_capture @ http://archive.notam02.no/arkiv/src/jack_capture-0.9.69.tar.gz
- unpacked it to my /0/comp/build-lin/xtra-progs/tarballs/
folder (use your own path)
- made a .jack_capture (dot jack_capture)
folder in my home folder & copied the config
file to it (else, error).
- entered make
- entered make install
and the rosegarden output saves to a jack_capture_##.wav
file in my home folder
It should be a simple edit in the rosegarden code to include an
"Export to wave file" menu item.
A provisional workaround under KDE
Save the following 3 lines as a text file under something like
~/command/jack-cast.txt & make it exetutable
# saves to
Place a "Quick Access" browser on your panel & set it up for
directory ~/command using single or double
click activation (trigger).
Next time your rosegarden is ready to play
something start jack_capture from your panel with
a click and hit the rosegarden play button.
When done hit enter into the terminal window opened for jack_capture.
Copy out the generated jack_capture_##.wav file as
To turn it into an mp3 I done did
ffmpeg -i jack_capture_##.wav
