I was just editing normalise to use dB when I realized MLT requires
that you suffix the value with "dB" otherwise it is interpreted as
float (%), but Kdenlive effects XML system has no way to add that
suffix. (It has a suffix it can display as a label in UI, but that is
not added to the value passed to MLT.)
