Edit the project in Kdenlive using unnormalized video clips you have, 
then render using audio-only profile to a .wav file, then normalize the 
file using an audio editor (for example the Audacity as suggested), then 
open up the kdenlive project again, add an empty audio track, put the 
edited wav to this track right from the beginning of the timeline, then 
mute or remove original sound track. I do it all the time (although 
using Ardour not Audacity).
