I'm just on my phone right now so i can't do this myself, but to generate a
debdiff I'd follow these steps:

1. Get the package from trusty. If you're running trusty, it's as easy as:

apt-get source soundconverter

If you're not on trusty, you can grab the package from launchpad. Just make
sure you get all the files, including the dsc and orig.tar.

2. Get the new package and download it to the same directory. Make sure the
new package has the debian directory in it already. If it doesn't, copy the
one from the trusty package and run "dch -i" to make a new changelog entry.

3. Build the new package by running "debuild"

4. You should now have two dsc files, one for the trusty version, one for
the new version. Run debdiff:

debdiff trusty.dsc new.dsc >soundconverter.diff

Hope that helps, let me know if you have any trouble.

Oh, and make sure that the diff doesn't contain anything that's not already
in vivid. SRU policy is that fixes must land in the development series
before being backported
