These files came from some analog-to-digital converter?  If you look  
at them with hexdump, there is stuff that looks like data only in the  
first 200 bytes or so.  The rest of the file looks likes zeros and  
the occasional 0x80bf.  I wouldn't expect the data read from these  
files to have a meaningful Fourier transform.

Cheers,
