Are you sure sample rate conversion was done on the sound file when saved out?
The lack of conversion would result in a faster sound file due to more data
being packed into it. I do not see an explicit sample rate conversion function
in Audacity in the menus, just project settings. Perhaps it does not work for 
you when you save.
