Testing for bit-accuracy --
Actually, open both wavs up in soundforge, find and mark a common sample point a few seconds after the very beginning of the wavs. Select and copy one of the wavs from the common sample point forward.
then, go to the other wave and instruct soundforge to mix the inverse (invert the wav? -- don't have soundforge here) of one wav with the other.
The result, if both are identical will be a ruler-flat line (zero db) for the lenght of the entire mixed wave (since music plus the inverse of the music would be silence). Any dropped sample, etc. would cause a spike in the mixed wave, or "music" to appear along the wave (albeit strange sounding distored music)
hope this helps
