  We propose a general approach to freezing out fluctuations in heavy-ion
collisions using the principle of maximum entropy. We find the results
naturally expressed as a direct relationship between the irreducible relative
correlators quantifying the deviations of hydrodynamic as well as hadron gas
fluctuations from the ideal hadron gas baseline. The method also allows us to
determine heretofore unknown parameters crucial for the freezeout of
fluctuations near the QCD critical point in terms of the QCD equation of state.
