I guess so. But its only guessing: You should never, never ever compress
a soundfile to MP3 or ogg if you plan to use it for anything else but
listening to it. Always use uncompressed WAV if you export a file to be
used in another app.
If the same data is compressed twice (first after exporting from Ardour
then again if exported from KDEnlive) the sound is bound to suffer.
You also should use the samplerate you plan to use in the Video, if you
export a file for soundtrack-purposes. 48KHz that is, even the jump from
a 44.1-file to 48 produces liestenable artifacts since the missing 400Hz
of data need to be interpolated.

best of luck, and keep us informed, weather this works or not...
