gnu/linux cards for dummies

required software:
https://wiki.archlinux.org/index.php/Xbindkeys
https://wiki.archlinux.org/index.php/FFmpeg
https://wiki.archlinux.org/index.php/PulseAudio
https://wiki.archlinux.org/index.php/Screen_capture#maim
https://github.com/astrand/xclip - can probably be installed with package manager on any major distro2
*maybe something else i dont remember, probably not

recording audio:
after installing ffmpeg and pulseaudio you open cml and type pacmd list-sinks | grep -e 'name:' -e 'index:' then choose which index is your soundcard (if you have more than one output source). in my case i only have my soundcard with index 0 as a default output source so i choose that. remember that number and open a text editor of your choice and create a bash script. paste this into it and save quit

#!/bin/bash
#Script for checking if ffmpeg is running and either starting the recording or terminating it.
SERVICE='ffmpeg'

if ps ax | grep -v grep | grep ${SERVICE} > /dev/null
then
        pkill ${SERVICE}
else
        timestamp=$(date +%s)
        echo -n "[sound:${timestamp}.mp3]" |xclip -sel cli
        ffmpeg -f pulse -i YOUROUTPUTSOURCEINDEX -map '0' ~/.local/share/Anki2/'User 1'/collection.media/${timestamp}.mp3
fi

what does this script do? it checks if ffmpeg is running. if it is, it terminates it. if it doesn't, it creates a UNIX timestamp that's copied to your clipboard and starts recording sound to your anki media folder (make sure that your media folder is placed there, and change accordingly). also remember to switch YOUROUTPUTSOURCEINDEX for the index you've previously determined with pacmd command. after recording you simply paste the contents of your clipboard to desired field in anki.

screenshots:
install maim and u can invoke screencapture of region of screen of ur choosing and copying to clipboard with maim -s | xclip -selection clipboard -t image/png in the cml

key shortcuts:
if u want key shortcuts read the page on Xbindkeys and configure it accordingly, dunno what ur distro might be using to init the DE/WM so that's on u. just read the arch wiki on xbindkeys linked above and u should be fine probably it explains everything very well. below are the contents of my ~/.xbindkeysrc file

#record audio for anime cards with recordingsound.sh script
"bash ~/bin/recordingsound.sh"
Control + slash

#screenshot an area and copy to clipboard
"maim -s | xclip -selection clipboard -t image/png"
Control + period
