My guess is that SoundConverter decimates the sample value or that the 
sample values were decimated during export to wav.
If you run the 'file' command on each of the FLAC files you'll probably 
see that the one exported from ardour is 24 bit and the one made with 
SoundConverter is 16 bit.

The file you filter through SoundConverter I assume you exported from 
Ardour to wav? If that is the case, did you perhaps export to 16 bit 
there (CD quality)?

If you export to 24 bit wav or perhaps even float wav from Ardour and 
then run the 'flac --best' command on it yourself how big is the 
resulting file then?
