If you don't have the original uncompressed recordings, I don't see how
you could be doing that. You'd have to guess how complex sounds are
supposed to fade out normally, to find out how much the fade out has been
And then, in the compressor, you have both a measurement of input volume
and a formula for turning that input volume into a gain to be applied, and
both of those parts are subject to a lot of variation and tweaking.
