[Stk] FileWvIn question

Hi,

I have been trying to use the classes FileWvIn and FileWvOut to test some 
signal processing code that I have been working on.  I have noticed that by 
default FileWvIn normalizes the sound file.  So, if I try to just make a 
copy of a sound file via FileWvIn and FileWvOut, the resulting sound file is 
quite a bit louder than the source file.  If I however turn off the 
normalization, FileWvIn outputs values that don't fall between -1 and 1 but 
are instead in the thousands.  These values obviously need to be scaled by 
some factor to get useable audio output.  So my question is: by what factor 
would these values have to be scaled in order to make an identical copy of 
the original sound file?

Thanks,
Greg
