NEW.dsc is made from your modified pulseaudio source tree (that was based on 'apt-get source'). Inside the source tree run 'debuild -S' to automatically generate a NEW.dsc in the parent directory of the source tree.
Now that you have both OLD.dsc and NEW.dsc you can make a debdiff:
debdiff OLD.dsc NEW.dsc > RESULT.debdiff
To make a debdiff you need two input files OLD.dsc and NEW.dsc.
OLD.dsc you get from the current release; either from 'apt-get source' or from: /launchpad. net/ubuntu/ +source/ pulseaudio/ 1:8.0-0ubuntu3. 4
