I'll try to explain more clearly.

As an experiment, I reversed a 16-bit, 44.1KHz piece of audio digitally 
using ProTools. I then reversed it again so it was playing the correct 
way (note: I reversed it again, physically putting it through the 
process, NOT simply Undoing the process which would be pointless.)

I then pasted the double-reversed file over an inverted copy of the 
original in order to see if there were any artefacts remaining. It 
cancelled out. Ergo: no change to the audio.

It seems as though we actually agree here, but we're at cross-purposes 
as to what I mean.

Martin.
