Hi Rodolfo, Should I have to mention, that it’s not recommended to work on the original files? Copy them within the Finder or your desktop of choice, so Audacity can manipulate the files, as it likes..

That’s strange! As playing two files at the same time, technically is a summing-function, if the result is louder than the single pieces, the invert didn’t work. Maybe one of the files was already inverted, before you got it. Just invert on one of the tracks again. Essential to the process is too, that both tracks sync exactly. So when you manually sync the beginning, do they still sync-match at or near the end of the file? You can and should zoom in on the waveform to do the syncing and checking. If they don’t sync-match completely, they are not identical, source-wise.
I wish a tool that detect the differences from files with different origines, sources and respective histories... Is that possibile?
I’m not aware of an application to do this job, automatically. Sorry! With kindest regards… …Maik Waschfeld
