i've downloaded xACT, which comes with shntool and i get the following result on a testfile
shntool [cmp]: warning: WAVE data size differs between these files -- will check up to smaller size
Comparing [/Users/zeropc/Desktop/wav-compare/Audio 2.wav] (0:17.867) and [/Users/zeropc/Desktop/wav-compare/Audio.wav] (0:15.963) : 0% 18% ERROR
shntool [cmp]: error: WAVE data differs at byte offset: 466847
is that okay or bad?
