Depends on the bats, but generally yes.  Some of them are on the edge of the 
human hearing range (I used to be able to hear the bats at my parents' house, 
although my hearing is no longer quite good enough).

First Google hit for "frequency range of bats" is a bit less optimistic than I 
am:

Either way, wouldn't the microphone be more of a limiting factor than the 
soundcard?
