Actually, you want to whiten it before output, not before input. Whitening before input is a problem, because you can't run an estimator on the input -- because it's been whitened.

If you want to know the unbiased entropy of a source, you want the raw inputs. If you don't care about the unbiased entropy, then you don't.
