Ohhhh! Now it's my turn for not reading closely. You even said that it was it
was interpolating between the values, and I read that to mean that it was
creating new interpolated samples.

Yep; there it is--thanks. You know, for all the flexibility and configuration
options in Cool Edit, I'm surprised that there is not an option to either
change the interpolation algorithm, or disable it. However, for things such as
FFT analysis, is the interpolated analog data being used, or the actual sampled
data? I just checked some newsgroups, but did not find anything useful.
Dave.
