Compare WAV files, Compare different WAV files of the same song Options

[Edskes]

I want to compare different WAV files containing the same song, these WAV files come from different CDs from different record companies and the WAV files are almost, but not exactly, the same filesize.
If I use WinDiff from the Microsoft Support Tools that sometimes works, then I see that both files are the same except the beginning and the end or that they are totally different. Only the problem is that WinDiff hangs on a lot of files, so that it doesn't show results.

So now I'm looking for either a better working version of WinDiff or another compare tool with support for binary files, or another way to compare WAV files with each other.

I think you're using the wrong approach. You're trying to see how different two audio files are by looking at the binary data. What you should do is load them in an audio editor like Adobe Audition and compare them in spectral and waveform view, and probably inverse-mixpasting both tracks (what's left will be the difference signal). As you know, half a second more silence before the start of one track can lead to 99% difference from then on, even when the actual audio is identical...
