I've never had that problem. I actually do this for every video
I've made for plug. I just use the export audio function from
within kdenlive and then do whatever processing I need to do on it
and then simply save it back out as a wav again (or more recently a
flac file so save space) and load it into kdenlive, making sure to
line the beginning of the audio clip up with the beginning of it's
video. They've lined up every single time. You just have to make
sure that you don't cut any parts out from either the video or the
audio before reassembling them in kdenlive.
That being said if you somehow did get your audio off, you'll need
for look for some visual clue as to when things happen and simply
slide the audio over until it lines up. I used to have to do this
for every single plug video when I first started because I was
capturing the audio completely separate from the video. Ideally you
would use a clapperboard or just simply have someone on camera clap
once so you could see the clap and line up the corresponding clap
sound with the clap motion.

All,
I have a video that I want to reduce noise. I can extract
the audio and cancell the noise via Audacity. However when I
try to join it to the video clip in Kdenlive it is out of
sync. I have looked and cannot find a solution for this. Any
help would be appreciated.
