You’re welcome. The only combination which personally I used to be successful with, I described in another forum.

Even editors like Audacity or Cool Edit Pro screwed up the data on my system, however that doesn’t seem to be the issue in your case.

In terms of comparison, I’d just rely on built-in tools like “fc” under Windows or something similar and a hex editor of your choice for synchronization as after all, you’ll hardly be able to catch exactly the same position of several recording runs.
